SPDX-License-Identifier: GPL-2.0 + +==================== +Kernel Testing Guide +==================== + + +There are a number of different tools for testing the Linux kernel, so knowing +when to use each of them can be a challenge. This document provides a rough +overview of their differences, and how they fit together. + + +Writing and Running Tests +========================= + +The bulk of kernel tests are written using either the kselftest or KUnit +frameworks. These both provide infrastructure to help make running tests and +groups of tests easier, as well as providing helpers to aid in writing new +tests. + +If you're looking to verify the behaviour of the Kernel — particularly specific +parts of the kernel — then you'll want to use KUnit or kselftest. + + +The Difference Between KUnit and kselftest +------------------------------------------ + +KUnit (Documentation/dev-tools/kunit/index.rst) is an entirely in-kernel system +for "white box" testing: because test code is part of the kernel, it can access +internal structures and functions which aren't exposed to userspace. + +KUnit tests therefore are best written against small, self-contained parts +of the kernel, which can be tested in isolation. This aligns well with the +concept of 'unit' testing. + +For example, a KUnit test might test an individual kernel function (or even a +single codepath through a function, such as an error handling case), rather +than a feature as a whole. + +This also makes KUnit tests very fast to build and run, allowing them to be +run frequently as part of the development process. + +There is a KUnit test style guide which may give further pointers in +Documentation/dev-tools/kunit/style.rst + + +kselftest (Documentation/dev-tools/kselftest.rst), on the other hand, is +largely implemented in userspace, and tests are normal userspace scripts or +programs. + +This makes it easier to write more complicated tests, or tests which need to +manipulate the overall system state more (e.g., spawning processes, etc.). +However, it's not possible to call kernel functions directly from kselftest. +This means that only kernel functionality which is exposed to userspace somehow +(e.g. by a syscall, device, filesystem, etc.) can be tested with kselftest. To +work around this, some tests include a companion kernel module which exposes +more information or functionality. If a test runs mostly or entirely within the +kernel, however, KUnit may be the more appropriate tool. + +kselftest is therefore suited well to tests of whole features, as these will +expose an interface to userspace, which can be tested, but not implementation +details. This aligns well with 'system' or 'end-to-end' testing. + +For example, all new system calls should be accompanied by kselftest tests. + +Code Coverage Tools +=================== + +The Linux Kernel supports two different code coverage measurement tools. These +can be used to verify that a test is executing particular functions or lines +of code. This is useful for determining how much of the kernel is being tested, +and for finding corner-cases which are not covered by the appropriate test. + +:doc:`gcov` is GCC's coverage testing tool, which can be used with the kernel +to get global or per-module coverage. Unlike KCOV, it does not record per-task +coverage. Coverage data can be read from debugfs, and interpreted using the +usual gcov tooling. + +:doc:`kcov` is a feature which can be built in to the kernel to allow +capturing coverage on a per-task level. It's therefore useful for fuzzing and +other situations where information about code executed during, for example, a +single syscall is useful. + + +Dynamic Analysis Tools +====================== + +The kernel also supports a number of dynamic analysis tools, which attempt to +detect classes of issues when they occur in a running kernel. These typically +each look for a different class of bugs, such as invalid memory accesses, +concurrency issues such as data races, or other undefined behaviour like +integer overflows. + +Some of these tools are listed below: + +* kmemleak detects possible memory leaks. See + Documentation/dev-tools/kmemleak.rst +* KASAN detects invalid memory accesses such as out-of-bounds and + use-after-free errors. See Documentation/dev-tools/kasan.rst +* UBSAN detects behaviour that is undefined by the C standard, like integer + overflows. See Documentation/dev-tools/ubsan.rst +* KCSAN detects data races. See Documentation/dev-tools/kcsan.rst +* KFENCE is a low-overhead detector of memory issues, which is much faster than + KASAN and can be used in production. See Documentation/dev-tools/kfence.rst +* lockdep is a locking correctness validator. See + Documentation/locking/lockdep-design.rst +* There are several other pieces of debug instrumentation in the kernel, many + of which can be found in lib/Kconfig.debug + +These tools tend to test the kernel as a whole, and do not "pass" like +kselftest or KUnit tests. They can be combined with KUnit or kselftest by +running tests on a kernel with these tools enabled: you can then be sure +that none of these errors are occurring during the test. + +Some of these tools integrate with KUnit or kselftest and will +automatically fail tests if an issue is detected. + diff --git a/Documentation/devicetree/bindings/arm/amlogic.yaml b/Documentation/devicetree/bindings/arm/amlogic.yaml index 5f6769bf45bd9f31723b997d45b1806f2f69a18a..97fb9626634435d73314d91b285e6ebba66a4da1 100644 --- a/Documentation/devicetree/bindings/arm/amlogic.yaml +++ b/Documentation/devicetree/bindings/arm/amlogic.yaml @@ -109,6 +109,7 @@ properties: - libretech,aml-s905d-pc - phicomm,n1 - smartlabs,sml5442tw + - videostrong,gxl-kii-pro - const: amlogic,s905d - const: amlogic,meson-gxl @@ -120,8 +121,10 @@ properties: - khadas,vim2 - kingnovel,r-box-pro - libretech,aml-s912-pc + - minix,neo-u9h - nexbox,a1 - tronsmart,vega-s96 + - videostrong,gxm-kiii-pro - wetek,core2 - const: amlogic,s912 - const: amlogic,meson-gxm diff --git a/Documentation/devicetree/bindings/arm/apple.yaml b/Documentation/devicetree/bindings/arm/apple.yaml new file mode 100644 index 0000000000000000000000000000000000000000..1e772c85206c01347a2be88568587abbbd2c881b --- /dev/null +++ b/Documentation/devicetree/bindings/arm/apple.yaml @@ -0,0 +1,64 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/arm/apple.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Apple ARM Machine Device Tree Bindings + +maintainers: + - Hector Martin <marcan@marcan.st> + +description: | + ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon". + + This currently includes devices based on the "M1" SoC, starting with the + three Mac models released in late 2020: + + - Mac mini (M1, 2020) + - MacBook Pro (13-inch, M1, 2020) + - MacBook Air (M1, 2020) + + The compatible property should follow this format: + + compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform"; + + <targettype> represents the board/device and comes from the `target-type` + property of the root node of the Apple Device Tree, lowercased.

A device driver must include + either <linux/io-64-nonatomic-lo-hi.h> or <linux/io-64-nonatomic-hi-lo.h> to + get the function definitions along with helpers that redirect the normal + readq()/writeq() to them on architectures that do not provide 64-bit access + natively. + +__raw_readq(), __raw_readl(), __raw_readw(), __raw_readb(), +__raw_writeq(), __raw_writel(), __raw_writew(), __raw_writeb() + + These are low-level MMIO accessors without barriers or byteorder changes and + architecture specific behavior. Accesses are usually atomic in the sense that + a four-byte __raw_readl() does not get split into individual byte loads, but + multiple consecutive accesses can be combined on the bus. In portable code, it + is only safe to use these to access memory behind a device bus but not MMIO + registers, as there are no ordering guarantees with regard to other MMIO + accesses or even spinlocks. The byte order is generally the same as for normal + memory, so unlike the other functions, these can be used to copy data between + kernel memory and device memory. + +inl(), inw(), inb(), outl(), outw(), outb() + + PCI I/O port resources traditionally require separate helpers as they are + implemented using special instructions on the x86 architecture. On most other + architectures, these are mapped to readl()/writel() style accessors + internally, usually pointing to a fixed area in virtual memory. Instead of an + ``__iomem`` pointer, the address is a 32-bit integer token to identify a port + number. PCI requires I/O port access to be non-posted, meaning that an outb() + must complete before the following code executes, while a normal writeb() may + still be in progress. On architectures that correctly implement this, I/O port + access is therefore ordered against spinlocks. Many non-x86 PCI host bridge + implementations and CPU architectures however fail to implement non-posted I/O + space on PCI, so they can end up being posted on such hardware. + + In some architectures, the I/O port number space has a 1:1 mapping to + ``__iomem`` pointers, but this is not recommended and device drivers should + not rely on that for portability. Similarly, an I/O port number as described + in a PCI base address register may not correspond to the port number as seen + by a device driver. Portable drivers need to read the port number for the + resource provided by the kernel. + + There are no direct 64-bit I/O port accessors, but pci_iomap() in combination + with ioread64/iowrite64 can be used instead. + +inl_p(), inw_p(), inb_p(), outl_p(), outw_p(), outb_p() + + On ISA devices that require specific timing, the _p versions of the I/O + accessors add a small delay.

Unlike the normal + MMIO accessors, these do not perform a byteswap on big-endian kernels, so the + first byte in the FIFO register corresponds to the first byte in the memory + buffer regardless of the architecture. + +Device memory mapping modes +=========================== + +Some architectures support multiple modes for mapping device memory. +ioremap_*() variants provide a common abstraction around these +architecture-specific modes, with a shared set of semantics. + +ioremap() is the most common mapping type, and is applicable to typical device +memory (e.g. I/O registers). Other modes can offer weaker or stronger +guarantees, if supported by the architecture. From most to least common, they +are as follows: + +ioremap() +--------- + +The default mode, suitable for most memory-mapped devices, e.g. control +registers. Memory mapped using ioremap() has the following characteristics: + +* Uncached - CPU-side caches are bypassed, and all reads and writes are handled + directly by the device +* No speculative operations - the CPU may not issue a read or write to this + memory, unless the instruction that does so has been reached in committed + program flow. +* No reordering - The CPU may not reorder accesses to this memory mapping with + respect to each other. On some architectures, this relies on barriers in + readl_relaxed()/writel_relaxed(). +* No repetition - The CPU may not issue multiple reads or writes for a single + program instruction. +* No write-combining - Each I/O operation results in one discrete read or write + being issued to the device, and multiple writes are not combined into larger + writes. This may or may not be enforced when using __raw I/O accessors or + pointer dereferences. +* Non-executable - The CPU is not allowed to speculate instruction execution + from this memory (it probably goes without saying, but you're also not + allowed to jump into device memory). + +On many platforms and buses (e.g. PCI), writes issued through ioremap() +mappings are posted, which means that the CPU does not wait for the write to +actually reach the target device before retiring the write instruction. + +On many platforms, I/O accesses must be aligned with respect to the access +size; failure to do so will result in an exception or unpredictable results. + +ioremap_wc() +------------ + +Maps I/O memory as normal memory with write combining. Unlike ioremap(), + +* The CPU may speculatively issue reads from the device that the program + didn't actually execute, and may choose to basically read whatever it wants. +* The CPU may reorder operations as long as the result is consistent from the + program's point of view. +* The CPU may write to the same location multiple times, even when the program + issued a single write. +* The CPU may combine several writes into a single larger write. + +This mode is typically used for video framebuffers, where it can increase +performance of writes. It can also be used for other blocks of memory in +devices (e.g. buffers or shared memory), but care must be taken as accesses are +not guaranteed to be ordered with respect to normal ioremap() MMIO register +accesses without explicit barriers. + +On a PCI bus, it is usually safe to use ioremap_wc() on MMIO areas marked as +``IORESOURCE_PREFETCH``, but it may not be used on those without the flag. +For on-chip devices, there is no corresponding flag, but a driver can use +ioremap_wc() on a device that is known to be safe. + +ioremap_wt() +------------ + +Maps I/O memory as normal memory with write-through caching. Like ioremap_wc(), +but also, + +* The CPU may cache writes issued to and reads from the device, and serve reads + from that cache. + +This mode is sometimes used for video framebuffers, where drivers still expect +writes to reach the device in a timely manner (and not be stuck in the CPU +cache), but reads may be served from the cache for efficiency. However, it is +rarely useful these days, as framebuffer drivers usually perform writes only, +for which ioremap_wc() is more efficient (as it doesn't needlessly trash the +cache). Most drivers should not use this. + +ioremap_np() +------------ + +Like ioremap(), but explicitly requests non-posted write semantics. On some +architectures and buses, ioremap() mappings have posted write semantics, which +means that writes can appear to "complete" from the point of view of the +CPU before the written data actually arrives at the target device. Writes are +still ordered with respect to other writes and reads from the same device, but +due to the posted write semantics, this is not the case with respect to other +devices. ioremap_np() explicitly requests non-posted semantics, which means +that the write instruction will not appear to complete until the device has +received (and to some platform-specific extent acknowledged) the written data. + +This mapping mode primarily exists to cater for platforms with bus fabrics that +require this particular mapping mode to work correctly. These platforms set the +``IORESOURCE_MEM_NONPOSTED`` flag for a resource that requires ioremap_np() +semantics and portable drivers should use an abstraction that automatically +selects it where appropriate (see the `Higher-level ioremap abstractions`_ +section below). + +The bare ioremap_np() is only available on some architectures; on others, it +always returns NULL. Drivers should not normally use it, unless they are +platform-specific or they derive benefit from non-posted writes where +supported, and can fall back to ioremap() otherwise. The normal approach to +ensure posted write completion is to do a dummy read after a write as +explained in `Accessing the device`_, which works with ioremap() on all +platforms. + +ioremap_np() should never be used for PCI drivers. PCI memory space writes are +always posted, even on architectures that otherwise implement ioremap_np(). +Using ioremap_np() for PCI BARs will at best result in posted write semantics, +and at worst result in complete breakage. + +Note that non-posted write semantics are orthogonal to CPU-side ordering +guarantees.

Specifically, this locking mechanism +is intended to prevent the dGPU, positioned in the base of the device, from +being hot-unplugged while in use. More details can be found in the +documentation for the detachment procedure below. By default, the latch is +unlocked. + +Detachment Procedure +-------------------- + +Note that the detachment process is governed fully by the EC. The +``surface_dtx`` driver only relays events from the EC to user-space and +commands from user-space to the EC, i.e. it does not influence this process. + +The detachment process is started with the user pressing the *detach* button +on the base of the device or executing the ``SDTX_IOCTL_LATCH_REQUEST`` IOCTL. +Following that: + +1. The EC turns on the indicator led on the detach-button, sends a + *detach-request* event (``SDTX_EVENT_REQUEST``), and awaits further + instructions/commands. In case the latch is unlocked, the led will flash + green. If the latch has been locked, the led will be solid red + +2. The event is, via the ``surface_dtx`` driver, relayed to user-space, where + an appropriate user-space daemon can handle it and send instructions back + to the EC via IOCTLs provided by this driver. + +3. The EC waits for instructions from user-space and acts according to them. + If the EC does not receive any instructions in a given period, it will + time out and continue as follows: + + - If the latch is unlocked, the EC will open the latch and the clipboard + can be detached from the base. This is the exact behavior as without + this driver or any user-space daemon. See the ``SDTX_IOCTL_LATCH_CONFIRM`` + description below for more details on the follow-up behavior of the EC. + + - If the latch is locked, the EC will *not* open the latch, meaning the + clipboard cannot be detached from the base. Furthermore, the EC sends + an cancel event (``SDTX_EVENT_CANCEL``) detailing this with the cancel + reason ``SDTX_DETACH_TIMEDOUT`` (see :ref:`events` for details). + +Valid responses by a user-space daemon to a detachment request event are: + +- Execute ``SDTX_IOCTL_LATCH_REQUEST``. This will immediately abort the + detachment process. Furthermore, the EC will send a detach-request event, + similar to the user pressing the detach-button to cancel said process (see + below). + +- Execute ``SDTX_IOCTL_LATCH_CONFIRM``. This will cause the EC to open the + latch, after which the user can separate clipboard and base. + + As this changes the latch state, a *latch-status* event + (``SDTX_EVENT_LATCH_STATUS``) will be sent once the latch has been opened + successfully. If the EC fails to open the latch, e.g. due to hardware + error or low battery, a latch-cancel event (``SDTX_EVENT_CANCEL``) will be + sent with the cancel reason indicating the specific failure. + + If the latch is currently locked, the latch will automatically be + unlocked before it is opened. + +- Execute ``SDTX_IOCTL_LATCH_HEARTBEAT``. This will reset the internal timeout. + No other actions will be performed, i.e. the detachment process will neither + be completed nor canceled, and the EC will still be waiting for further + responses. + +- Execute ``SDTX_IOCTL_LATCH_CANCEL``. This will abort the detachment process, + similar to ``SDTX_IOCTL_LATCH_REQUEST``, described above, or the button + press, described below. A *generic request* event (``SDTX_EVENT_REQUEST``) + is send in response to this. In contrast to those, however, this command + does not trigger a new detachment process if none is currently in + progress. + +- Do nothing. The detachment process eventually times out as described in + point 3. + +See :ref:`ioctls` for more details on these responses. + +It is important to note that, if the user presses the detach button at any +point when a detachment operation is in progress (i.e. after the EC has sent +the initial *detach-request* event (``SDTX_EVENT_REQUEST``) and before it +received the corresponding response concluding the process), the detachment +process is canceled on the EC-level and an identical event is being sent. +Thus a *detach-request* event, by itself, does not signal the start of the +detachment process. + +The detachment process may further be canceled by the EC due to hardware +failures or a low clipboard battery. This is done via a cancel event +(``SDTX_EVENT_CANCEL``) with the corresponding cancel reason. + + +User-Space Interface Documentation +================================== + +Error Codes and Status Values +----------------------------- + +Error and status codes are divided into different categories, which can be +used to determine if the status code is an error, and, if it is, the +severity and type of that error.

Contents: + + - Overview. + - Buffered read helpers. + - Read helper functions. + - Read helper structures. + - Read helper operations. + - Read helper procedure. + - Read helper cache API. + + +Overview +======== + +The network filesystem helper library is a set of functions designed to aid a +network filesystem in implementing VM/VFS operations. For the moment, that +just includes turning various VM buffered read operations into requests to read +from the server. The helper library, however, can also interpose other +services, such as local caching or local data encryption. + +Note that the library module doesn't link against local caching directly, so +access must be provided by the netfs. + + +Buffered Read Helpers +===================== + +The library provides a set of read helpers that handle the ->readpage(), +->readahead() and much of the ->write_begin() VM operations and translate them +into a common call framework. + +The following services are provided: + + * Handles transparent huge pages (THPs). + + * Insulates the netfs from VM interface changes. + + * Allows the netfs to arbitrarily split reads up into pieces, even ones that + don't match page sizes or page alignments and that may cross pages. + + * Allows the netfs to expand a readahead request in both directions to meet + its needs. + + * Allows the netfs to partially fulfil a read, which will then be resubmitted. + + * Handles local caching, allowing cached data and server-read data to be + interleaved for a single request. + + * Handles clearing of bufferage that aren't on the server. + + * Handle retrying of reads that failed, switching reads from the cache to the + server as necessary. + + * In the future, this is a place that other services can be performed, such as + local encryption of data to be stored remotely or in the cache. + +From the network filesystem, the helpers require a table of operations. This +includes a mandatory method to issue a read operation along with a number of +optional methods. + + +Read Helper Functions +--------------------- + +Three read helpers are provided:: + + * void netfs_readahead(struct readahead_control *ractl, + const struct netfs_read_request_ops *ops, + void *netfs_priv);`` + * int netfs_readpage(struct file *file, + struct page *page, + const struct netfs_read_request_ops *ops, + void *netfs_priv); + * int netfs_write_begin(struct file *file, + struct address_space *mapping, + loff_t pos, + unsigned int len, + unsigned int flags, + struct page **_page, + void **_fsdata, + const struct netfs_read_request_ops *ops, + void *netfs_priv); + +Each corresponds to a VM operation, with the addition of a couple of parameters +for the use of the read helpers: + + * ``ops`` + + A table of operations through which the helpers can talk to the filesystem. + + * ``netfs_priv`` + + Filesystem private data (can be NULL). + +Both of these values will be stored into the read request structure. + +For ->readahead() and ->readpage(), the network filesystem should just jump +into the corresponding read helper; whereas for ->write_begin(), it may be a +little more complicated as the network filesystem might want to flush +conflicting writes or track dirty data and needs to put the acquired page if an +error occurs after calling the helper. + +The helpers manage the read request, calling back into the network filesystem +through the suppplied table of operations. Waits will be performed as +necessary before returning for helpers that are meant to be synchronous. + +If an error occurs and netfs_priv is non-NULL, ops->cleanup() will be called to +deal with it. If some parts of the request are in progress when an error +occurs, the request will get partially completed if sufficient data is read. + +Additionally, there is:: + + * void netfs_subreq_terminated(struct netfs_read_subrequest *subreq, + ssize_t transferred_or_error, + bool was_async); + +which should be called to complete a read subrequest. This is given the number +of bytes transferred or a negative error code, plus a flag indicating whether +the operation was asynchronous (ie. whether the follow-on processing can be +done in the current context, given this may involve sleeping). + + +Read Helper Structures +---------------------- + +The read helpers make use of a couple of structures to maintain the state of +the read. The first is a structure that manages a read request as a whole:: + + struct netfs_read_request { + struct inode *inode; + struct address_space *mapping; + struct netfs_cache_resources cache_resources; + void *netfs_priv; + loff_t start; + size_t len; + loff_t i_size; + const struct netfs_read_request_ops *netfs_ops; + unsigned int debug_id; + ... + }; + +The above fields are the ones the netfs can use. They are: + + * ``inode`` + * ``mapping`` + + The inode and the address space of the file being read from. The mapping + may or may not point to inode->i_data. + + * ``cache_resources`` + + Resources for the local cache to use, if present. + + * ``netfs_priv`` + + The network filesystem's private data. The value for this can be passed in + to the helper functions or set during the request. The ->cleanup() op will + be called if this is non-NULL at the end. + + * ``start`` + * ``len`` + + The file position of the start of the read request and the length. These + may be altered by the ->expand_readahead() op. + + * ``i_size`` + + The size of the file at the start of the request. + + * ``netfs_ops`` + + A pointer to the operation table. The value for this is passed into the + helper functions. + + * ``debug_id`` + + A number allocated to this operation that can be displayed in trace lines + for reference. + + +The second structure is used to manage individual slices of the overall read +request:: + + struct netfs_read_subrequest { + struct netfs_read_request *rreq; + loff_t start; + size_t len; + size_t transferred; + unsigned long flags; + unsigned short debug_index; + ... + }; + +Each subrequest is expected to access a single source, though the helpers will +handle falling back from one source type to another. The members are: + + * ``rreq`` + + A pointer to the read request. + + * ``start`` + * ``len`` + + The file position of the start of this slice of the read request and the + length. + + * ``transferred`` + + The amount of data transferred so far of the length of this slice. The + network filesystem or cache should start the operation this far into the + slice. If a short read occurs, the helpers will call again, having updated + this to reflect the amount read so far. + + * ``flags`` + + Flags pertaining to the read. There are two of interest to the filesystem + or cache: + + * ``NETFS_SREQ_CLEAR_TAIL`` + + This can be set to indicate that the remainder of the slice, from + transferred to len, should be cleared. + + * ``NETFS_SREQ_SEEK_DATA_READ`` + + This is a hint to the cache that it might want to try skipping ahead to + the next data (ie. using SEEK_DATA). + + * ``debug_index`` + + A number allocated to this slice that can be displayed in trace lines for + reference. + + +Read Helper Operations +---------------------- + +The network filesystem must provide the read helpers with a table of operations +through which it can issue requests and negotiate:: + + struct netfs_read_request_ops { + void (*init_rreq)(struct netfs_read_request *rreq, struct file *file); + bool (*is_cache_enabled)(struct inode *inode); + int (*begin_cache_operation)(struct netfs_read_request *rreq); + void (*expand_readahead)(struct netfs_read_request *rreq); + bool (*clamp_length)(struct netfs_read_subrequest *subreq); + void (*issue_op)(struct netfs_read_subrequest *subreq); + bool (*is_still_valid)(struct netfs_read_request *rreq); + int (*check_write_begin)(struct file *file, loff_t pos, unsigned len, + struct page *page, void **_fsdata); + void (*done)(struct netfs_read_request *rreq); + void (*cleanup)(struct address_space *mapping, void *netfs_priv); + }; + +The operations are as follows: + + * ``init_rreq()`` + + [Optional] This is called to initialise the request structure. It is given + the file for reference and can modify the ->netfs_priv value. + + * ``is_cache_enabled()`` + + [Required] This is called by netfs_write_begin() to ask if the file is being + cached. It should return true if it is being cached and false otherwise. + + * ``begin_cache_operation()`` + + [Optional] This is called to ask the network filesystem to call into the + cache (if present) to initialise the caching state for this read. The netfs + library module cannot access the cache directly, so the cache should call + something like fscache_begin_read_operation() to do this. + + The cache gets to store its state in ->cache_resources and must set a table + of operations of its own there (though of a different type). + + This should return 0 on success and an error code otherwise. If an error is + reported, the operation may proceed anyway, just without local caching (only + out of memory and interruption errors cause failure here). + + * ``expand_readahead()`` + + [Optional] This is called to allow the filesystem to expand the size of a + readahead read request. The filesystem gets to expand the request in both + directions, though it's not permitted to reduce it as the numbers may + represent an allocation already made. If local caching is enabled, it gets + to expand the request first. + + Expansion is communicated by changing ->start and ->len in the request + structure. Note that if any change is made, ->len must be increased by at + least as much as ->start is reduced. + + * ``clamp_length()`` + + [Optional] This is called to allow the filesystem to reduce the size of a + subrequest. The filesystem can use this, for example, to chop up a request + that has to be split across multiple servers or to put multiple reads in + flight. + + This should return 0 on success and an error code on error. + + * ``issue_op()`` + + [Required] The helpers use this to dispatch a subrequest to the server for + reading. In the subrequest, ->start, ->len and ->transferred indicate what + data should be read from the server. + + There is no return value; the netfs_subreq_terminated() function should be + called to indicate whether or not the operation succeeded and how much data + it transferred. The filesystem also should not deal with setting pages + uptodate, unlocking them or dropping their refs - the helpers need to deal + with this as they have to coordinate with copying to the local cache. + + Note that the helpers have the pages locked, but not pinned. It is possible + to use the ITER_XARRAY iov iterator to refer to the range of the inode that + is being operated upon without the need to allocate large bvec tables. + + * ``is_still_valid()`` + + [Optional] This is called to find out if the data just read from the local + cache is still valid. It should return true if it is still valid and false + if not. If it's not still valid, it will be reread from the server. + + * ``check_write_begin()`` + + [Optional] This is called from the netfs_write_begin() helper once it has + allocated/grabbed the page to be modified to allow the filesystem to flush + conflicting state before allowing it to be modified. + + It should return 0 if everything is now fine, -EAGAIN if the page should be + regrabbed and any other error code to abort the operation. + + * ``done`` + + [Optional] This is called after the pages in the request have all been + unlocked (and marked uptodate if applicable). + + * ``cleanup`` + + [Optional] This is called as the request is being deallocated so that the + filesystem can clean up ->netfs_priv. + + + +Read Helper Procedure +--------------------- + +The read helpers work by the following general procedure: + + * Set up the request. + + * For readahead, allow the local cache and then the network filesystem to + propose expansions to the read request. This is then proposed to the VM. + If the VM cannot fully perform the expansion, a partially expanded read will + be performed, though this may not get written to the cache in its entirety. + + * Loop around slicing chunks off of the request to form subrequests: + + * If a local cache is present, it gets to do the slicing, otherwise the + helpers just try to generate maximal slices. + + * The network filesystem gets to clamp the size of each slice if it is to be + the source. This allows rsize and chunking to be implemented. + + * The helpers issue a read from the cache or a read from the server or just + clears the slice as appropriate. + + * The next slice begins at the end of the last one. + + * As slices finish being read, they terminate. + + * When all the subrequests have terminated, the subrequests are assessed and + any that are short or have failed are reissued: + + * Failed cache requests are issued against the server instead. + + * Failed server requests just fail. + + * Short reads against either source will be reissued against that source + provided they have transferred some more data: + + * The cache may need to skip holes that it can't do DIO from. + + * If NETFS_SREQ_CLEAR_TAIL was set, a short read will be cleared to the + end of the slice instead of reissuing. + + * Once the data is read, the pages that have been fully read/cleared: + + * Will be marked uptodate. + + * If a cache is present, will be marked with PG_fscache. + + * Unlocked + + * Any pages that need writing to the cache will then have DIO writes issued. + + * Synchronous operations will wait for reading to be complete. + + * Writes to the cache will proceed asynchronously and the pages will have the + PG_fscache mark removed when that completes. + + * The request structures will be cleaned up when everything has completed. + + +Read Helper Cache API +--------------------- + +When implementing a local cache to be used by the read helpers, two things are +required: some way for the network filesystem to initialise the caching for a +read request and a table of operations for the helpers to call. + +The network filesystem's ->begin_cache_operation() method is called to set up a +cache and this must call into the cache to do the work. If using fscache, for +example, the cache would call:: + + int fscache_begin_read_operation(struct netfs_read_request *rreq, + struct fscache_cookie *cookie); + +passing in the request pointer and the cookie corresponding to the file. + +The netfs_read_request object contains a place for the cache to hang its +state:: + + struct netfs_cache_resources { + const struct netfs_cache_ops *ops; + void *cache_priv; + void *cache_priv2; + }; + +This contains an operations table pointer and two private pointers. The +operation table looks like the following:: + + struct netfs_cache_ops { + void (*end_operation)(struct netfs_cache_resources *cres); + + void (*expand_readahead)(struct netfs_cache_resources *cres, + loff_t *_start, size_t *_len, loff_t i_size); + + enum netfs_read_source (*prepare_read)(struct netfs_read_subrequest *subreq, + loff_t i_size); + + int (*read)(struct netfs_cache_resources *cres, + loff_t start_pos, + struct iov_iter *iter, + bool seek_data, + netfs_io_terminated_t term_func, + void *term_func_priv); + + int (*write)(struct netfs_cache_resources *cres, + loff_t start_pos, + struct iov_iter *iter, + netfs_io_terminated_t term_func, + void *term_func_priv); + }; + +With a termination handler function pointer:: + + typedef void (*netfs_io_terminated_t)(void *priv, + ssize_t transferred_or_error, + bool was_async); + +The methods defined in the table are: + + * ``end_operation()`` + + [Required] Called to clean up the resources at the end of the read request. + + * ``expand_readahead()`` + + [Optional] Called at the beginning of a netfs_readahead() operation to allow + the cache to expand a request in either direction. This allows the cache to + size the request appropriately for the cache granularity. + + The function is passed poiners to the start and length in its parameters, + plus the size of the file for reference, and adjusts the start and length + appropriately. It should return one of: + + * ``NETFS_FILL_WITH_ZEROES`` + * ``NETFS_DOWNLOAD_FROM_SERVER`` + * ``NETFS_READ_FROM_CACHE`` + * ``NETFS_INVALID_READ`` + + to indicate whether the slice should just be cleared or whether it should be + downloaded from the server or read from the cache - or whether slicing + should be given up at the current point. + + * ``prepare_read()`` + + [Required] Called to configure the next slice of a request. ->start and + ->len in the subrequest indicate where and how big the next slice can be; + the cache gets to reduce the length to match its granularity requirements. + + * ``read()`` + + [Required] Called to read from the cache. The start file offset is given + along with an iterator to read to, which gives the length also. It can be + given a hint requesting that it seek forward from that start position for + data. + + Also provided is a pointer to a termination handler function and private + data to pass to that function. The termination function should be called + with the number of bytes transferred or an error code, plus a flag + indicating whether the termination is definitely happening in the caller's + context. + + * ``write()`` + + [Required] Called to write to the cache.

或者，您可以在正在运行的内核上使用gdb（只读的；即不能更改值或设置断点）。 + 为此，请首先使用-g编译内核；适当地编辑arch/x86/Makefile，然后执行 ``make + clean`` 。您还需要启用CONFIG_PROC_FS（通过 ``make config`` ）。 + + 使用新内核重新启动后，执行 ``gdb vmlinux /proc/kcore`` 。现在可以使用所有 + 普通的gdb命令。查找系统崩溃点的命令是 ``l *0xXXXXXXXX`` （将xxx替换为EIP + 值）。 + + 用gdb无法调试一个当前未运行的内核是由于gdb（错误地）忽略了编译内核的起始 + 偏移量。 diff --git a/Documentation/translations/zh_CN/admin-guide/bug-bisect.rst b/Documentation/translations/zh_CN/admin-guide/bug-bisect.rst new file mode 100644 index 0000000000000000000000000000000000000000..662eb5b46e84ec2190c4ee388936621ef43f644b --- /dev/null +++ b/Documentation/translations/zh_CN/admin-guide/bug-bisect.rst @@ -0,0 +1,81 @@ +.. include:: ../disclaimer-zh_CN.rst + +:Original: :doc:`../../../admin-guide/bug-bisect` + +:译者: + + 吴想成 Wu XiangCheng <bobwxc@email.cn> + +二分（bisect）缺陷 ++++++++++++++++++++ + +（英文版）最后更新：2016年10月28日 + +引言 +===== + +始终尝试由来自kernel.org的源代码构建的最新内核。如果您没有信心这样做，请将 +错误报告给您的发行版供应商，而不是内核开发人员。 + +找到缺陷（bug）并不总是那么容易，不过仍然得去找。如果你找不到它，不要放弃。 +尽可能多的向相关维护人员报告您发现的信息。请参阅MAINTAINERS文件以了解您所 +关注的子系统的维护人员。 + +在提交错误报告之前，请阅读“Documentation/admin-guide/reporting-issues.rst”。 + +设备未出现（Devices not appearing） +==================================== + +这通常是由udev/systemd引起的。在将其归咎于内核之前先检查一下。 + +查找导致缺陷的补丁 +=================== + +使用 ``git`` 提供的工具可以很容易地找到缺陷，只要缺陷是可复现的。 + +操作步骤： + +- 从git源代码构建内核 +- 以此开始二分 [#f1]_:: + + $ git bisect start + +- 标记损坏的变更集:: + + $ git bisect bad [commit] + +- 标记正常工作的变更集:: + + $ git bisect good [commit] + +- 重新构建内核并测试 +- 使用以下任一与git bisect进行交互:: + + $ git bisect good + + 或:: + + $ git bisect bad + + 这取决于您测试的变更集上是否有缺陷 +- 在一些交互之后，git bisect将给出可能导致缺陷的变更集。 + +- 例如，如果您知道当前版本有问题，而4.8版本是正常的，则可以执行以下操作:: + + $ git bisect start + $ git bisect bad # Current version is bad + $ git bisect good v4.8 + + +..

+上面的简明指南概述了如何向Linux内核开发人员报告问题。对于已经熟悉向自由和开 +源软件（FLOSS）项目报告问题的人来说，这可能是他们所需要的全部内容。对于其他 +人，本部分更为详细，并一步一步地描述。为了便于阅读，它仍然尽量简洁，并省略 +了许多细节；这些在逐步指南后的参考章节中进行了描述，该章节更详细地解释了每 +个步骤。 + +注意：本节涉及的方面比简明指南多，顺序也稍有不同。这符合你的利益，以确保您 +尽早意识到看起来像Linux内核毛病的问题可能实际上是由其他原因引起的。这些步骤 +可以确保你最终不会觉得在这一过程中投入的时间是浪费： + + * 您是否面临硬件或软件供应商提供的Linux内核的问题？那么基本上您最好停止阅读 + 本文档，转而向您的供应商报告问题，除非您愿意自己安装最新的Linux版本。寻找 + 和解决问题往往需要后者。 + + * 使用您喜爱的网络搜索引擎对现有报告进行粗略搜索；此外，请检查 + `Linux内核邮件列表（LKML） <https://lore.kernel.org/lkml/>`_ 的存档。如果 + 找到匹配的报告，请加入讨论而不是发送新报告。 + + * 看看你正在处理的问题是否为回归问题、安全问题或非常严重的问题：这些都是需 + 要在接下来的一些步骤中特别处理的“高优先级问题”。 + + * 确保不是内核环境导致了您面临的问题。 + + * 创建一个新的备份，并将系统修复和恢复工具放在手边。 + + * 确保您的系统不会通过动态构建额外的内核模块来增强其内核，像DKMS这样的解决 + 方案可能在您不知情的情况下就在本地进行了这样的工作。 + + * 当问题发生时，检查您的内核是否被“污染”，因为使内核设置这个标志的事件可能 + 会导致您面临的问题。 + + * 粗略地写下如何重现这个问题。如果您同时处理多个问题，请为每个问题单独写注 + 释，并确保它们在新启动的系统上独立出现。这是必要的，因为每个问题都需要分 + 别报告给内核开发人员，除非它们严重纠缠在一起。 + + * 如果您正面临稳定版或长期支持版本线的回归（例如从5.10.4更新到5.10.5时出现 + 故障），请查看后文“报告稳定版和长期支持内核线的回归”小节。 + + * 定位可能引起问题的驱动程序或内核子系统。找出其开发人员期望的报告的方式和 + 位置。注意：大多数情况下不会是 bugzilla.kernel.org，因为问题通常需要通 + 过邮件发送给维护人员和公共邮件列表。 + + * 在缺陷追踪器或问题相关邮件列表的存档中彻底搜索可能与您的问题匹配的报告。 + 如果你发现了一些相关讨论，请加入讨论而不是发送新的报告。 + +在完成这些准备之后，你将进入主要部分： + + * 除非您已经在运行最新的“主线”Linux内核，否则最好在报告流程前安装它。在某些 + 情况下，使用最新的“稳定版”Linux进行测试和报告也是可以接受的替代方案；在 + 合并窗口期间，这实际上可能是最好的方法，但在开发阶段最好还是暂停几天。无论 + 你选择什么版本，最好使用“普通”构建。忽略这些建议会大大增加您的报告被拒绝 + 或忽略的风险。 + + * 确保您刚刚安装的内核在运行时不会“污染”自己。 + + * 在您刚刚安装的内核中复现这个问题。如果它没有出现，请查看下方只发生在 + 稳定版和长期支持内核的问题的说明。 + + * 优化你的笔记：试着找到并写出最直接的复现问题的方法。确保最终结果包含所有 + 重要的细节，同时让第一次听说的人容易阅读和理解。如果您在此过程中学到了一 + 些东西，请考虑再次搜索关于该问题的现有报告。 + + * 如果失败涉及“panic”、“Oops”、“warning”或“BUG”，请考虑解码内核日志以查找触 + 发错误的代码行。 + + * 如果您的问题是回归问题，请尽可能缩小引入问题时的范围。 + + * 通过详细描述问题来开始编写报告。记得包括以下条目：您为复现而安装的最新内 + 核版本、使用的Linux发行版以及关于如何复现该问题的说明。如果可能，将内核 + 构建配置（.config）和 ``dmesg`` 的输出放在网上的某个地方，并链接到它。包 + 含或上传所有其他可能相关的信息，如Oops的输出/截图或来自 ``lspci`` 的输出 + 。一旦你写完了这个主要部分，请在上方插入一个正常长度的段落快速概述问题和 + 影响。再在此之上添加一个简单描述问题的句子，以得到人们的阅读。现在给出一 + 个更短的描述性标题或主题。然后就可以像MAINTAINERS文件告诉你的那样发送或 + 提交报告了，除非你在处理一个“高优先级问题”：它们需要按照下面“高优先级问 + 题的特殊处理”所述特别关照。 + + * 等待别人的反应，继续推进事情，直到你能够接受这样或那样的结果。因此，请公 + 开和及时地回应任何询问。测试提出的修复。积极地测试：至少重新测试每个新主 + 线版本的首个候选版本（RC），并报告你的结果。如果出现拖延，就友好地提醒一 + 下。如果你没有得到任何帮助或者未能满意，请试着自己帮助自己。 + + +报告稳定版和长期支持内核线的回归 +---------------------------------- + +如果您发现了稳定版或长期支持内核版本线中的回归问题并按上述流程跳到这里，那么 +请阅读本小节。即例如您在从5.10.4更新到5.10.5时出现了问题（从5.9.15到5.10.5则 +不是）。开发人员希望尽快修复此类回归，因此有一个简化流程来报告它们： + + * 检查内核开发人员是否仍然维护你关心的Linux内核版本线：去 `kernel.org 的首页 + <https://kernel.org/>`_ ，确保此特定版本线的最新版没有“[EOL]”标记。 + + * 检查 `Linux稳定版邮件列表 <https://lore.kernel.org/stable/>`_ 中的现有报告。 + + * 从特定的版本线安装最新版本作为纯净内核。确保这个内核没有被污染，并且仍然 + 存在问题，因为问题可能已经在那里被修复了。如果您第一次发现供应商内核的问题， + 请检查已知最新版本的普通构建是否可以正常运行。 + + * 向Linux稳定版邮件列表发送一个简短的问题报告(stable@vger.kernel.org)。大致 + 描述问题，并解释如何复现。讲清楚首个出现问题的版本和最后一个工作正常的版本。 + 然后等待进一步的指示。 + +下面的参考章节部分详细解释了这些步骤中的每一步。 + + +报告只发生在较旧内核版本线的问题 +---------------------------------- + +若您尝试了上述的最新主线内核，但未能在那里复现问题，那么本小节适用于您；以下 +流程有助于使问题在仍然支持的稳定版或长期支持版本线，或者定期基于最新稳定版或 +长期支持内核的供应商内核中得到修复。如果是这种情况，请执行以下步骤： + + * 请做好准备，接下来的几个步骤可能无法在旧版本中解决问题：修复可能太大或太 + 冒险，无法移植到那里。 + + * 执行前节“报告稳定版和长期支持内核线的回归”中的前三个步骤。 + + * 在Linux内核版本控制系统中搜索修复主线问题的更改，因为它的提交消息可能会 + 告诉你修复是否已经计划好了支持。如果你没有找到，搜索适当的邮件列表，寻找 + 讨论此类问题或同行评议可能修复的帖子；然后检查讨论是否认为修复不适合支持。 + 如果支持根本不被考虑，加入最新的讨论，询问是否有可能。 + + * 前面的步骤之一应该会给出一个解决方案。如果仍未能成功，请向可能引起问题的 + 子系统的维护人员询问建议；抄送特定子系统的邮件列表以及稳定版邮件列表 + +下面的参考章节部分详细解释了这些步骤中的每一步。 + + +参考章节：向内核维护者报告问题 +=============================== + +上面的详细指南简要地列出了所有主要步骤，这对大多数人来说应该足够了。但有时， +即使是有经验的用户也可能想知道如何实际执行这些步骤之一。这就是本节的目的， +因为它将提供关于上述每个步骤的更多细节。请将此作为参考文档：可以从头到尾 +阅读它。但它主要是为了浏览和查找如何实际执行这些步骤的详细信息。 + +在深入挖掘细节之前，我想先给你一些一般性建议： + + * Linux内核开发人员很清楚这个过程很复杂，比其他的FLOSS项目要求更多。我们很 + 希望让它更简单。但这需要在不同的地方以及一些基础设施上付诸努力，这些基础 + 设施需要持续的维护；尚未有人站出来做这些工作，所以目前情况就是这样。 + + * 与某些供应商签订的保证或支持合同并不能使您有权要求上游Linux内核社区的开 + 发人员进行修复：这样的合同完全在Linux内核、其开发社区和本文档的范围之外。 + 这就是为什么在这种情况下，你不能要求任何契约保证，即使开发人员处理的问 + 题对供应商有效。如果您想主张您的权利，使用供应商的支持渠道代替。当这样做 + 的时候，你可能想提出你希望看到这个问题在上游Linux内核中修复；可以这是确 + 保最终修复将被纳入所有Linux发行版的唯一方法来鼓励他们。 + + * 如果您从未向FLOSS项目报告过任何问题，那么您应该考虑阅读 `如何有效地报告 + 缺陷 <https://www.chiark.greenend.org.uk/~sgtatham/bugs.html>`_ ， `如何 + 以明智的方式提问 <http://www.catb.org/esr/faqs/smart-questions.html>`_ ， + 和 `如何提出好问题 <https://jvns.ca/blog/good-questions/>`_ 。 + +解决这些问题之后，可以在下面找到如何正确地向Linux内核报告问题的详细信息。 + + +确保您使用的是上游Linux内核 +---------------------------- + + *您是否面临硬件或软件供应商提供的Linux内核的问题？那么基本上您最好停止阅 + 读本文档，转而向您的供应商报告问题，除非您愿意自己安装最新的Linux版本。 + 寻找和解决问题往往需要后者。* + +与大多数程序员一样，Linux内核开发人员不喜欢花时间处理他们维护的源代码中根本 +不会发生的问题的报告。这只会浪费每个人的时间，尤其是你的时间。不幸的是，当 +涉及到内核时，这样的情况很容易发生，并且常常导致双方气馁。这是因为几乎所有预 +装在设备（台式机、笔记本电脑、智能手机、路由器等）上的Linux内核，以及大多数 +由Linux发行商提供的内核，都与由kernel.org发行的官方Linux内核相距甚远：从Linux +开发的角度来看，这些供应商提供的内核通常是古老的或者经过了大量修改，通常两点 +兼具。 + +大多数供应商内核都不适合用来向Linux内核开发人员报告问题：您在其中遇到的问题 +可能已经由Linux内核开发人员在数月或数年前修复；此外，供应商的修改和增强可能 +会导致您面临的问题，即使它们看起来很小或者完全不相关。这就是为什么您应该向 +供应商报告这些内核的问题。它的开发者应该查看报告，如果它是一个上游问题，直接 +于上游修复或将报告转发到那里。在实践中，这有时行不通。因此，您可能需要考虑 +通过自己安装最新的Linux内核内核来绕过供应商。如果如果您选择此方法，那么本指 +南后面的步骤将解释如何在排除了其他可能导致您的问题的原因后执行此操作。 + +注意前段使用的词语是“大多数”，因为有时候开发人员实际上愿意处理供应商内核出现 +的问题报告。他们是否这么做很大程度上取决于开发人员和相关问题。如果发行版只 +根据最近的Linux版本对内核进行了较小修改，那么机会就比较大；例如对于Debian +GNU/Linux Sid或Fedora Rawhide所提供的主线内核。一些开发人员还将接受基于最新 +稳定内核的发行版内核问题报告，只要它改动不大；例如Arch Linux、常规Fedora版本 +和openSUSE Turboweed。但是请记住，您最好使用主线Linux，并避免在此流程中使用 +稳定版内核，如“安装一个新的内核进行测试”一节中所详述。 + +当然，您可以忽略所有这些建议，并向上游Linux开发人员报告旧的或经过大量修改的 +供应商内核的问题。但是注意，这样的报告经常被拒绝或忽视，所以自行小心考虑一下。 +不过这还是比根本不报告问题要好：有时候这样的报告会直接或间接地帮助解决之后的 +问题。 + + +搜索现有报告（第一部分） +------------------------- + + *使用您喜爱的网络搜索引擎对现有报告进行粗略搜索；此外，请检查Linux内核 + 邮件列表（LKML）的存档。如果找到匹配的报告，请加入讨论而不是发送新报告。* + +报告一个别人已经提出的问题，对每个人来说都是浪费时间，尤其是作为报告人的你。 +所以彻底检查是否有人已经报告了这个问题，这对你自己是有利的。在流程中的这一步， +可以只执行一个粗略的搜索：一旦您知道您的问题需要报告到哪里，稍后的步骤将告诉 +您如何详细搜索。尽管如此，不要仓促完成这一步，它可以节省您的时间和减少麻烦。 + +只需先用你最喜欢的搜索引擎在互联网上搜索。然后再搜索Linux内核邮件列表（LKML） +存档。 + +如果搜索结果实在太多，可以考虑让你的搜索引擎将搜索时间范围限制在过去的一个 +月或一年。而且无论你在哪里搜索，一定要用恰当的搜索关键词；也要变化几次关键 +词。同时，试着从别人的角度看问题：这将帮助你想出其他的关键词。另外，一定不 +要同时使用过多的关键词。记住搜索时要同时尝试包含和不包含内核驱动程序的名称 +或受影响的硬件组件的名称等信息。但其确切的品牌名称（比如说“华硕红魔 Radeon +RX 5700 XT Gaming OC”）往往帮助不大，因为它太具体了。相反，尝试搜索术语，如 +型号（Radeon 5700 或 Radeon 5000）和核心代号（“Navi”或“Navi10”），以及包含 +和不包含其制造商（“AMD”）。 + +如果你发现了关于你的问题的现有报告，请加入讨论，因为你可能会提供有价值的额 +外信息。这一点很重要，即使是在修复程序已经准备好或处于最后阶段，因为开发人 +员可能会寻找能够提供额外信息或测试建议修复程序的人。跳到“发布报告后的责任” +一节，了解有关如何正确参与的细节。 + +注意，搜索 `bugzilla.kernel.org <https://bugzilla.kernel.org/>`_ 网站可能 +也是一个好主意，因为这可能会提供有价值的见解或找到匹配的报告。如果您发现后者， +请记住：大多数子系统都希望在不同的位置报告，如下面“你需要将问题报告到何处” +一节中所述。因此本应处理这个问题的开发人员甚至可能不知道bugzilla的工单。所以 +请检查工单中的问题是否已经按照本文档所述得到报告，如果没有，请考虑这样做。 + +高优先级的问题？ +----------------- + + *看看你正在处理的问题是否是回归问题、安全问题或非常严重的问题：这些都是 + 需要在接下来的一些步骤中特别处理的“高优先级问题”。* + +Linus Torvalds和主要的Linux内核开发人员希望看到一些问题尽快得到解决，因此在 +报告过程中有一些“高优先级问题”的处理略有不同。有三种情况符合条件:回归、安全 +问题和非常严重的问题。 + +如果在旧版本的Linux内核中工作的东西不能在新版本的Linux内核中工作，或者某种 +程度上在新版本的Linux内核中工作得更差，那么你就需要处理“回归”。因此，当一个 +在Linux 5.7中表现良好的WiFi驱动程序在5.8中表现不佳或根本不能工作时，这是一 +种回归。如果应用程序在新的内核中出现不稳定的现象，这也是一种回归，这可能是 +由于内核和用户空间之间的接口（如procfs和sysfs）发生不兼容的更改造成的。显著 +的性能降低或功耗增加也可以称为回归。但是请记住:新内核需要使用与旧内核相似的 +配置来构建（参见下面如何实现这一点）。这是因为内核开发人员在实现新特性时有 +时无法避免不兼容性；但是为了避免回归，这些特性必须在构建配置期间显式地启用。 + +什么是安全问题留给您自己判断。在继续之前，请考虑阅读 +“Documentation/translations/zh_CN/admin-guide/security-bugs.rst”， +因为它提供了如何最恰当地处理安全问题的额外细节。 + +当发生了完全无法接受的糟糕事情时，此问题就是一个“非常严重的问题”。例如， +Linux内核破坏了它处理的数据或损坏了它运行的硬件。当内核突然显示错误消息 +（“kernel panic”）并停止工作，或者根本没有任何停止信息时，您也在处理一个严重 +的问题。注意：不要混淆“panic”（内核停止自身的致命错误）和“Oops”（可恢复错误）， +因为显示后者之后内核仍然在运行。 + + +确保环境健康 +-------------- + + *确保不是内核所处环境导致了你所面临的问题。* + +看起来很像内核问题的问题有时是由构建或运行时环境引起的。很难完全排除这种问 +题，但你应该尽量减少这种问题： + + * 构建内核时，请使用经过验证的工具，因为编译器或二进制文件中的错误可能会导 + 致内核出现错误行为。 + + * 确保您的计算机组件在其设计规范内运行；这对处理器、内存和主板尤为重要。因 + 此，当面临潜在的内核问题时，停止低电压或超频。 + + * 尽量确保不是硬件故障导致了你的问题。例如，内存损坏会导致大量的问题，这些 + 问题会表现为看起来像内核问题。 + + * 如果你正在处理一个文件系统问题，你可能需要用 ``fsck`` 检查一下文件系统， + 因为它可能会以某种方式被损坏，从而导致无法预期的内核行为。 + + * 在处理回归问题时，要确保没有在更新内核的同时发生了其他变化。例如，这个问 + 题可能是由同时更新的其他软件引起的。也有可能是在你第一次重启进入新内核时， + 某个硬件巧合地坏了。更新系统 BIOS 或改变 BIOS 设置中的某些内容也会导致 + 一些看起来很像内核回归的问题。 + + +为紧急情况做好准备 +------------------- + + *创建一个全新的备份，并将系统修复和还原工具放在手边* + +我得提醒您，您正在和计算机打交道，计算机有时会出现意想不到的事情，尤其是当 +您折腾其操作系统的内核等关键部件时。而这就是你在这个过程中要做的事情。因此， +一定要创建一个全新的备份；还要确保你手头有修复或重装操作系统的所有工具， +以及恢复备份所需的一切。 + + +确保你的内核不会被增强 +------------------------ + + *确保您的系统不会通过动态构建额外的内核模块来增强其内核，像DKMS这样的解 + 决方案可能在您不知情的情况下就在本地进行了这样的工作。* + +如果内核以任何方式得到增强，那么问题报告被忽略或拒绝的风险就会急剧增加。这就 +是为什么您应该删除或禁用像akmods和DKMS这样的机制：这些机制会自动构建额外内核 +模块，例如当您安装新的Linux内核或第一次引导它时。也要记得同时删除他们可能安装 +的任何模块。然后重新启动再继续。 + +注意，你可能不知道你的系统正在使用这些解决方案之一：当你安装 Nvidia 专有图 +形驱动程序、VirtualBox 或其他需要 Linux 内核以外的模块支持的软件时，它们通 +常会静默设置。这就是为什么你可能需要卸载这些软件的软件包，以摆脱任何第三方 +内核模块。 + + +检查“污染”标志 +---------------- + + *当问题发生时，检查您的内核是否被“污染”，因为使内核设置这个标志的事件可 + 能会导致您面临的问题。* + +当某些可能会导致看起来完全不相关的后续错误的事情发生时，内核会用“污染 +（taint）”标志标记自己。如果您的内核受到污染，那么您面临的可能是这样的错误。 +因此在投入更多时间到这个过程中之前，尽早排除此情况可能对你有好处。这是这个 +步骤出现在这里的唯一原因，因为这个过程稍后会告诉您安装最新的主线内核；然后 +您将需要再次检查污染标志，因为当它出问题的时候内核报告会关注它。 + +在正在运行的系统上检查内核是否污染非常容易：如果 ``cat /proc/sys/kernel/tainted`` +返回“0”，那么内核没有被污染，一切正常。在某些情况下无法检查该文件；这就是 +为什么当内核报告内部问题（“kernel bug”）、可恢复错误（“kernel Oops”）或停止 +操作前不可恢复的错误（“kernel panic”）时，它也会提到污染状态。当其中一个错 +误发生时，查看打印的错误消息的顶部，搜索以“CPU:”开头的行。如果发现问题时内 +核未被污染，那么它应该以“Not infected”结束；如果你看到“Tainted:”且后跟一些 +空格和字母，那就被污染了。 + +如果你的内核被污染了，请阅读“Documentation/translations/zh_CN/admin-guide/tainted-kernels.rst” +以找出原因。设法消除污染因素。通常是由以下三种因素之一引起的： + + 1. 发生了一个可恢复的错误（“kernel Oops”），内核污染了自己，因为内核知道在 + 此之后它可能会出现奇怪的行为错乱。在这种情况下，检查您的内核或系统日志， + 并寻找以下列文字开头的部分:: + + Oops: 0000 [#1] SMP + + 如方括号中的“#1”所示，这是自启动以来的第一次Oops。每个Oops和此后发生的 + 任何其他问题都可能是首个Oops的后续问题，即使这两个问题看起来完全不相关。 + 通过消除首个Oops的原因并在之后复现该问题，可以排除这种情况。有时仅仅 + 重新启动就足够了，有时更改配置后重新启动可以消除Oops。但是在这个流程中 + 不要花费太多时间在这一点上，因为引起Oops的原因可能已经在您稍后将按流程 + 安装的新Linux内核版本中修复了。 + + 2. 您的系统使用的软件安装了自己的内核模块，例如Nvidia的专有图形驱动程序或 + VirtualBox。当内核从外部源（即使它们是开源的）加载此类模块时，它会污染 + 自己：它们有时会在不相关的内核区域导致错误，从而可能导致您面临的问题。 + 因此，当您想要向Linux内核开发人员报告问题时，您必须阻止这些模块加载。 + 大多数情况下最简单的方法是：临时卸载这些软件，包括它们可能已经安装的任 + 何模块。之后重新启动。 + + 3. 当内核加载驻留在Linux内核源代码staging树中的模块时，它也会污染自身。这 + 是一个特殊的区域，代码（主要是驱动程序）还没有达到正常Linux内核的质量 + 标准。当您报告此种模块的问题时，内核受到污染显然是没有问题的；只需确保 + 问题模块是造成污染的唯一原因。如果问题发生在一个不相关的区域，重新启动 + 并通过指定 ``foo.blacklist=1`` 作为内核参数临时阻止该模块被加载（用有 + 问题的模块名替换“foo”）。 + + +记录如何重现问题 +------------------ + + *粗略地写下如何重现这个问题。如果您同时处理多个问题，请为每个问题单独写 + 注释，并确保它们在新启动的系统上独立出现。这是必要的，因为每个问题都需 + 要分别报告给内核开发人员，除非它们严重纠缠在一起。* + +如果你同时处理多个问题，必须分别报告每个问题，因为它们可能由不同的开发人员 +处理。在一份报告中描述多种问题，也会让其他人难以将其分开。因此只有在问题严 +重纠缠的情况下，才能将问题合并在一份报告中。 + +此外，在报告过程中，你必须测试该问题是否发生在其他内核版本上。因此，如果您 +知道如何在一个新启动的系统上快速重现问题，将使您的工作更加轻松。 + +注意：报告只发生过一次的问题往往是没有结果的，因为它们可能是由于宇宙辐射导 +致的位翻转。所以你应该尝试通过重现问题来排除这种情况，然后再继续。如果你有 +足够的经验来区分由于硬件故障引起的一次性错误和难以重现的罕见内核问题，可以 +忽略这个建议。 + + +稳定版或长期支持内核的回归？ +----------------------------- + + *如果您正面临稳定版或长期支持版本线的回归（例如从5.10.4更新到5.10.5时出现 + 故障），请查看后文“报告稳定版和长期支持内核线的回归”小节。* + +稳定版和长期支持内核版本线中的回归是Linux开发人员非常希望解决的问题，这样的 +问题甚至比主线开发分支中的回归更不应出现，因为它们会很快影响到很多人。开发人员 +希望尽快了解此类问题，因此有一个简化流程来报告这些问题。注意，使用更新内核版 +本线的回归（比如从5.9.15切换到5.10.5时出现故障）不符合条件。 + + +你需要将问题报告到何处 +------------------------ + + *定位可能引起问题的驱动程序或内核子系统。找出其开发人员期望的报告的方式 + 和位置。注意：大多数情况下不会是bugzilla.kernel.org，因为问题通常需要通 + 过邮件发送给维护人员和公共邮件列表。* + +将报告发送给合适的人是至关重要的，因为Linux内核是一个大项目，大多数开发人员 +只熟悉其中的一小部分。例如，相当多的程序员只关心一个驱动程序，比如一个WiFi +芯片驱动程序；它的开发人员可能对疏远的或不相关的“子系统”（如TCP堆栈、 +PCIe/PCI子系统、内存管理或文件系统）的内部知识了解很少或完全不了解。 + +问题在于：Linux内核缺少一个，可以简单地将问题归档并让需要了解它的开发人员了 +解它的，中心化缺陷跟踪器。这就是为什么你必须找到正确的途径来自己报告问题。 +您可以在脚本的帮助下做到这一点（见下文），但它主要针对的是内核开发人员和专 +家。对于其他人来说，MAINTAINERS（维护人员）文件是更好的选择。 + +如何阅读MAINTAINERS维护者文件 +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +为了说明如何使用 :ref:`MAINTAINERS <maintainers>` 文件，让我们假设您的笔记 +本电脑中的WiFi在更新内核后突然出现了错误行为。这种情况下可能是WiFi驱动的问 +题。显然，它也可能由于驱动基于的某些代码，但除非你怀疑有这样的东西会附着在 +驱动程序上。如果真的是其他的问题，驱动程序的开发人员会让合适的人参与进来。 + +遗憾的是，没有通用且简单的办法来检查哪个代码驱动了特定硬件组件。 + +在WiFi驱动出现问题的情况下，你可能想查看 ``lspci -k`` 的输出，因为它列出了 +PCI/PCIe总线上的设备和驱动它的内核模块:: + + [user@something ~]$ lspci -k + [...] + 3a:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) + Subsystem: Bigfoot Networks, Inc. Device 1535 + Kernel driver in use: ath10k_pci + Kernel modules: ath10k_pci + [...] + +但如果你的WiFi芯片通过USB或其他内部总线连接，这种方法就行不通了。在这种情况 +下，您可能需要检查您的WiFi管理器或 ``ip link`` 的输出。寻找有问题的网络接口 +的名称，它可能类似于“wlp58s0”。此名称可以用来找到驱动它的模块:: + + [user@something ~]$ realpath --relative-to=/sys/module//sys/class/net/wlp58s0/device/driver/module + ath10k_pci + +如果这些技巧不能进一步帮助您，请尝试在网上搜索如何缩小相关驱动程序或子系统 +的范围。如果你不确定是哪一个：试着猜一下，即使你猜得不好，也会有人会帮助你 +的。 + +一旦您知道了相应的驱动程序或子系统，您就希望在MAINTAINERS文件中搜索它。如果 +是“ath10k_pci”，您不会找到任何东西，因为名称太具体了。有时你需要在网上寻找 +帮助；但在此之前，请尝试使用一个稍短或修改过的名称来搜索MAINTAINERS文件，因 +为这样你可能会发现类似这样的东西:: + + QUALCOMM ATHEROS ATH10K WIRELESS DRIVER + Mail: A. Some Human <shuman@example.com> + Mailing list: ath10k@lists.infradead.org + Status: Supported + Web-page: https://wireless.wiki.kernel.org/en/users/Drivers/ath10k + SCM: git git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git + Files: drivers/net/wireless/ath/ath10k/ + +注意：如果您阅读在Linux源代码树的根目录中找到的原始维护者文件，则行描述将是 +缩写。例如，“Mail:（邮件）”将是“M:”，“Mailing list:（邮件列表）”将是“L”， +“Status:（状态）”将是“S:”。此文件顶部有一段解释了这些和其他缩写。 + +首先查看“Status”状态行。理想情况下，它应该得到“Supported（支持）”或 +“Maintained（维护）”。如果状态为“Obsolete（过时的）”，那么你在使用一些过时的 +方法，需要转换到新的解决方案上。有时候，只有在感到有动力时，才会有人为代码 +提供“Odd Fixes”。如果碰见“Orphan”，你就完全不走运了，因为再也没有人关心代码 +了，只剩下这些选项:准备好与问题共存，自己修复它，或者找一个愿意修复它的程序员。 + +检查状态后，寻找以“bug:”开头的一行：它将告诉你在哪里可以找到子系统特定的缺 +陷跟踪器来提交你的问题。上面的例子没有此行。大多数部分都是这样，因为 Linux +内核的开发完全是由邮件驱动的。很少有子系统使用缺陷跟踪器，且其中只有一部分 +依赖于 bugzilla.kernel.org。 + +在这种以及其他很多情况下，你必须寻找以“Mail:”开头的行。这些行提到了特定代码 +的维护者的名字和电子邮件地址。也可以查找以“Mailing list:”开头的行，它告诉你 +开发代码的公共邮件列表。你的报告之后需要通过邮件发到这些地址。另外，对于所有 +通过电子邮件发送的问题报告，一定要抄送 Linux Kernel Mailing List（LKML） +<linux-kernel@vger.kernel.org>。在以后通过邮件发送问题报告时，不要遗漏任何 +一个邮件列表!维护者都是大忙人，可能会把一些工作留给子系统特定列表上的其他开 +发者；而 LKML 很重要，因为需要一个可以找到所有问题报告的地方。 + + +借助脚本找到维护者 +~~~~~~~~~~~~~~~~~~~~ + +对于手头有Linux源码的人来说，有第二个可以找到合适的报告地点的选择：脚本 +“scripts/get_maintainer.pl”，它尝试找到所有要联系的人。它会查询MAINTAINERS +文件，并需要用相关源代码的路径来调用。对于编译成模块的驱动程序，经常可以用 +这样的命令找到:: + + $ modinfo ath10k_pci | grep filename | sed 's!/lib/modules/.*/kernel/!!; s!filename:!!; s!\.ko\(\|\.xz\)!!' + drivers/net/wireless/ath/ath10k/ath10k_pci.ko + +将其中的部分内容传递给脚本:: + + $ ./scripts/get_maintainer.pl -f drivers/net/wireless/ath/ath10k* + Some Human <shuman@example.com> (supporter:QUALCOMM ATHEROS ATH10K WIRELESS DRIVER) + Another S.

DRIVERS (WIRELESS)) + netdev@vger.kernel.org (open list:NETWORKING DRIVERS) + linux-kernel@vger.kernel.org (open list) + +不要把你的报告发给所有的人。发送给维护者，脚本称之为“supporter:”；另外抄送 +代码最相关的邮件列表，以及 Linux 内核邮件列表（LKML）。在此例中，你需要将报 +告发送给 “Some Human <shuman@example.com>” ，并抄送 +“ath10k@lists.infradead.org”和“linux-kernel@vger.kernel.org”。 + +注意：如果你用 git 克隆了 Linux 源代码，你可能需要用--git 再次调用 +get_maintainer.pl。脚本会查看提交历史，以找到最近哪些人参与了相关代码的编写， +因为他们可能会提供帮助。但要小心使用这些结果，因为它很容易让你误入歧途。 +例如，这种情况常常会发生在很少被修改的地方（比如老旧的或未维护的驱动程序）： +有时这样的代码会在树级清理期间被根本不关心此驱动程序的开发者修改。 + + +搜索现有报告（第二部分） +-------------------------- + + *在缺陷追踪器或问题相关邮件列表的存档中彻底搜索可能与您的问题匹配的报告。 + 如果找到匹配的报告，请加入讨论而不是发送新报告。* + +如前所述：报告一个别人已经提出的问题，对每个人来说都是浪费时间，尤其是作为报告 +人的你。这就是为什么你应该再次搜索现有的报告。现在你已经知道问题需要报告到哪里。 +如果是邮件列表，那么一般在 `lore.kernel.org <https://lore.kernel.org/>`_ 可以 +找到相应存档。 + +但有些列表运行在其他地方。例如前面步骤中当例子的ath10k WiFi驱动程序就是这种 +情况。但是你通常可以在网上很容易地找到这些列表的档案。例如搜索“archive +ath10k@lists.infradead.org”，将引导您到ath10k邮件列表的信息页，该页面顶部链接 +到其 `列表存档 <https://lists.infradead.org/pipermail/ath10k/>`_ 。遗憾的是， +这个列表和其他一些列表缺乏搜索其存档的功能。在这种情况下可以使用常规的互联网 +搜索引擎，并添加类似“site:lists.infadead.org/pipermail/ath10k/”这 +样的搜索条件，这会把结果限制在该链接中的档案。 + +也请进一步搜索网络、LKML和bugzilla.kernel.org网站。 + +有关如何搜索以及在找到匹配报告时如何操作的详细信息，请参阅上面的“搜索现有报告 +（第一部分）”。 + +不要急着完成报告过程的这一步：花30到60分钟甚至更多的时间可以为你和其他人节省 / +减少相当多的时间和麻烦。 + + +安装一个新的内核进行测试 +-------------------------- + + *除非您已经在运行最新的“主线”Linux内核，否则最好在报告流程前安装它。在 + 某些情况下，使用最新的“稳定版”Linux进行测试和报告也是可以接受的替代方案； + 在合并窗口期间，这实际上可能是最好的方法，但在开发阶段最好还是暂停几天。 + 无论你选择什么版本，最好使用“普通”构建。忽略这些建议会大大增加您的报告 + 被拒绝或忽略的风险。* + +正如第一步的详细解释中所提到的：与大多数程序员一样，与大多数程序员一样，Linux +内核开发人员不喜欢花时间处理他们维护的源代码中根本不会发生的问题的报告。这只 +会浪费每个人的时间，尤其是你的时间。这就是为什么在报告问题之前，您必须先确认 +问题仍然存在于最新的上游代码中，这符合每个人的利益。您可以忽略此建议，但如前 +所述：这样做会极大地增加问题报告被拒绝或被忽略的风险。 + +内核“最新上游”的范围通常指： + + * 安装一个主线内核；最新的稳定版内核也可以是一个选择，但大多数时候都最好避免。 + 长期支持内核（有时称为“LTS内核”）不适合此流程。下一小节将更详细地解释所有 + 这些。 + + * 下一小节描述获取和安装这样一个内核的方法。它还指出了使用预编译内核是可以的， + 但普通的内核更好，这意味着：它是直接使用从 `kernel.org <https://kernel.org/>`_ + 获得的Linux源代码构建并且没有任何方式修改或增强。 + + +选择适合测试的版本 +~~~~~~~~~~~~~~~~~~~~ + +前往 `kernel.org <https://kernel.org/>`_ 来决定使用哪个版本。忽略那个写着 +“Latest release最新版本”的巨大黄色按钮，往下看有一个表格。在表格的顶部，你会 +看到一行以“mainline”开头的字样，大多数情况下它会指向一个版本号类似“5.8-rc2” +的预发布版本。如果是这样的话，你将需要使用这个主线内核进行测试。不要让“rc” +吓到你，这些“开发版内核”实际上非常可靠——而且你已经按照上面的指示做了备份， +不是吗？ + +大概每九到十周，“mainline”可能会给你指出一个版本号类似“5.7”的正式版本。如果 +碰见这种情况，请考虑暂停报告过程，直到下一个版本的第一个预发布（5.8-rc1）出 +现在 `kernel.org <https://kernel.org/>`_ 上。这是因为 Linux 的开发周期正在 +两周的“合并窗口”内。大部分的改动和所有干扰性的改动都会在这段时间内被合并到 +下一个版本中。在此期间使用主线是比较危险的。内核开发者通常也很忙，可能没有 +多余的时间来处理问题报告。这也是很有可能在合并窗口中应用了许多修改来修复你 +所面临的问题；这就是为什么你很快就得用一个新的内核版本重新测试，就像下面“发 +布报告后的责任”一节中所述的那样。 + +这就是为什么要等到合并窗口结束后才去做。但是如果你处理的是一些不应该等待的 +东西，则无需这样做。在这种情况下，可以考虑通过 git 获取最新的主线内核（见下 +文），或者使用 kernel.org 上提供的最新稳定版本。如果 mainline 因为某些原因 +不无法正常工作，那么使用它也是可以接受的。总的来说：用它来重现问题也比完全 +不报告问题要好。 + +最好避免在合并窗口外使用最新的稳定版内核，因为所有修复都必须首先应用于主线。 +这就是为什么检查最新的主线内核是如此重要：你希望看到在旧版本线修复的任何问题 +需要先在主线修复，然后才能得到回传，这可能需要几天或几周。另一个原因是：您 +希望的修复对于回传来说可能太难或太冒险；因此再次报告问题不太可能改变任何事情。 + +这些方面也部分表明了为什么长期支持内核（有时称为“LTS内核”）不适合报告流程： +它们与当前代码的距离太远。因此，先去测试主线，然后再按流程走：如果主线没有 +出现问题，流程将指导您如何在旧版本线中修复它。 + +如何获得新的 Linux 内核 +~~~~~~~~~~~~~~~~~~~~~~~~~ + +你可以使用预编译或自编译的内核进行测试；如果你选择后者，可以使用 git 获取源 +代码，或者下载其 tar 存档包。 + +**使用预编译的内核** ：这往往是最快速、最简单、最安全的方法——尤其是在你不熟 +悉 Linux 内核的情况下。问题是：发行商或附加存储库提供的大多数版本都是从修改 +过的Linux源代码构建的。因此它们不是普通的，通常不适合于测试和问题报告：这些 +更改可能会导致您面临的问题或以某种方式影响问题。 + +但是如果您使用的是流行的Linux发行版，那么您就很幸运了：对于大部分的发行版， +您可以在网上找到包含最新主线或稳定版本Linux内核包的存储库。使用这些是完全可 +以的，只要从存储库的描述中确认它们是普通的或者至少接近普通。此外，请确保软件 +包包含kernel.org上提供的最新版本内核。如果这些软件包的时间超过一周，那么它们 +可能就不合适了，因为新的主线和稳定版内核通常至少每周发布一次。 + +请注意，您以后可能需要手动构建自己的内核：有时这是调试或测试修复程序所必需的， +如后文所述。还要注意，预编译的内核可能缺少在出现panic、Oops、warning或BUG时 +解码内核打印的消息所需的调试符号；如果您计划解码这些消息，最好自己编译内核 +（有关详细信息，请参阅本小节结尾和“解码失败信息”小节）。 + +**使用git** ：熟悉 git 的开发者和有经验的 Linux 用户通常最好直接从 +`kernel.org 上的官方开发仓库 +<https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/>`_ +中获取最新的 Linux 内核源代码。这些很可能比最新的主线预发布版本更新一些。不 +用担心：它们和正式的预发布版本一样可靠，除非内核的开发周期目前正处于合并窗 +口中。不过即便如此，它们也是相当可靠的。 + +**常规方法** ：不熟悉 git 的人通常最好从 `kernel.org <https://kernel.org/>`_ +下载源码的tar 存档包。 + +如何实际构建一个内核并不在这里描述，因为许多网站已经解释了必要的步骤。如果 +你是新手，可以考虑按照那些建议使用 ``make localmodconfig`` 来做，它将尝试获 +取你当前内核的配置，然后根据你的系统进行一些调整。这样做并不能使编译出来的 +内核更好，但可以更快地编译。 + +注意：如果您正在处理来自内核的pannc、Oops、warning或BUG，请在配置内核时尝试 +启用 CONFIG_KALLSYMS 选项。此外，还可以启用 CONFIG_DEBUG_KERNEL 和 +CONFIG_DEBUG_INFO；后者是相关选项，但只有启用前者才能开启。请注意， +CONFIG_DEBUG_INFO 会需要更多储存空间来构建内核。但这是值得的，因为这些选项将 +允许您稍后精确定位触发问题的确切代码行。下面的“解码失败信息”一节对此进行了更 +详细的解释。 + +但请记住：始终记录遇到的问题，以防难以重现。发送未解码的报告总比不报告要好。 + + +检查“污染”标志 +---------------- + + *确保您刚刚安装的内核在运行时不会“污染”自己。* + +正如上面已经详细介绍过的：当发生一些可能会导致一些看起来完全不相关的后续错 +误的事情时，内核会设置一个“污染”标志。这就是为什么你需要检查你刚刚安装的内 +核是否有设置此标志。如果有的话，几乎在任何情况下你都需要在报告问题之前先消 +除它。详细的操作方法请看上面的章节。 + + +用新内核重现问题 +------------------ + + *在您刚刚安装的内核中复现这个问题。如果它没有出现，请查看下方只发生在 + 稳定版和长期支持内核的问题的说明。* + +检查这个问题是否发生在你刚刚安装的新 Linux 内核版本上。如果新内核已经修复了， +可以考虑使用此版本线，放弃报告问题。但是请记住，只要它没有在 `kernel.org +<https://kernel.org/>`_ 的稳定版和长期版（以及由这些版本衍生出来的厂商内核） +中得到修复，其他用户可能仍然会受到它的困扰。如果你喜欢使用其中的一个，或 +者只是想帮助它们的用户，请前往下面的“报告只发生在较旧内核版本线的问题”一节。 + + +优化复现问题的描述 +-------------------- + + *优化你的笔记：试着找到并写出最直接的复现问题的方法。确保最终结果包含所 + 有重要的细节，同时让第一次听说的人容易阅读和理解。如果您在此过程中学到 + 了一些东西，请考虑再次搜索关于该问题的现有报告。* + +过于复杂的报告会让别人很难理解。因此请尽量找到一个可以直接描述、易于以书面 +形式理解的再现方法。包含所有重要的细节，但同时也要尽量保持简短。 + +在这在前面的步骤中，你很可能已经了解了一些关于你所面临的问题的点。利用这些 +知识，再次搜索可以转而加入的现有报告。 + + +解码失败信息 +------------- + + *如果失败涉及“panic”、“Oops”、“warning”或“BUG”，请考虑解码内核日志以查找 + 触发错误的代码行。* + +当内核检测到内部问题时，它会记录一些有关已执行代码的信息。这使得在源代码中精 +确定位触发问题的行并显示如何调用它成为可能。但只有在配置内核时启用了 +CONFIG_DEBUG_INFO 和 CONFIG_KALLSYMS选项时，这种方法才起效。如果已启用此选项， +请考虑解码内核日志中的信息。这将使我们更容易理解是什么导致了“panic”、“Oops”、 +“warning”或“BUG”，从而增加了有人提供修复的几率。 + +解码可以通过Linux源代码树中的脚本来完成。如果您运行的内核是之前自己编译的， +这样这样调用它:: + + [user@something ~]$ sudo dmesg | ./linux-5.10.5/scripts/decode_stacktrace.sh ./linux-5.10.5/vmlinux + /usr/lib/debug/lib/modules/5.10.10-4.1.x86_64/vmlinux /usr/src/kernels/5.10.10-4.1.x86_64/ + +如果您运行的是打包好的普通内核，则可能需要安装带有调试符号的相应包。然后按以下 +方式调用脚本（如果发行版未打包，则可能需要从Linux源代码获取）:: + + [user@something ~]$ sudo dmesg | ./linux-5.10.5/scripts/decode_stacktrace.sh \ + /usr/lib/debug/lib/modules/5.10.10-4.1.x86_64/vmlinux /usr/src/kernels/5.10.10-4.1.x86_64/ + +脚本将解码如下的日志行，这些日志行显示内核在发生错误时正在执行的代码的地址:: + + [ 68.387301] RIP: 0010:test_module_init+0x5/0xffa [test_module] + +解码之后，这些行将变成这样:: + + [ 68.387301] RIP: 0010:test_module_init (/home/username/linux-5.10.5/test-module/test-module.c:16) test_module + +在本例中，执行的代码是从文件“~/linux-5.10.5/test-module/test-module.c”构建的， +错误出现在第16行的指令中。 + +该脚本也会如此解码以“Call trace”开头的部分中提到的地址，该部分显示出现问题的 +函数的路径。此外，脚本还会显示内核正在执行的代码部分的汇编输出。 + +注意，如果你没法做到这一点，只需跳过这一步，并在报告中说明原因。如果你幸运的 +话，可能无需解码。如果需要的话，也许有人会帮你做这件事情。还要注意，这只是解 +码内核堆栈跟踪的几种方法之一。有时需要采取不同的步骤来检索相关的详细信息。 +别担心，如果您碰到的情况需要这样做，开发人员会告诉您该怎么做。 + + +对回归的特别关照 +----------------- + + *如果您的问题是回归问题，请尽可能缩小引入问题时的范围。* + +Linux 首席开发者 Linus Torvalds 认为 Linux 内核永远不应恶化，这就是为什么他 +认为回归是不可接受的，并希望看到它们被迅速修复。这就是为什么引入了回归的改 +动导致的问题若无法通过其他方式快速解决，通常会被迅速撤销。因此，报告回归有 +点像“王炸”，会迅速得到修复。但要做到这一点，需要知道导致回归的变化。通常情 +况下，要由报告者来追查罪魁祸首，因为维护者往往没有时间或手头设置不便来自行 +重现它。 + +有一个叫做“二分”的过程可以来寻找变化，这在 +“Documentation/translations/zh_CN/admin-guide/bug-bisect.rst”文档中进行了详细 +的描述，这个过程通常需要你构建十到二十个内核镜像，每次都尝试在构建下一个镜像 +之前重现问题。是的，这需要花费一些时间，但不用担心，它比大多数人想象的要快得多。 +多亏了“binary search二进制搜索”，这将引导你在源代码管理系统中找到导致回归的提交。 +一旦你找到它，就在网上搜索其主题、提交ID和缩短的提交ID（提交ID的前12个字符）。 +如果有的话，这将引导您找到关于它的现有报告。 + +需要注意的是，二分法需要一点窍门，不是每个人都懂得诀窍，也需要相当多的努力， +不是每个人都愿意投入。尽管如此，还是强烈建议自己进行一次二分。如果你真的 +不能或者不想走这条路，至少要找出是哪个主线内核引入的回归。比如说从 5.5.15 +切换到 5.8.4 的时候出现了一些问题，那么至少可以尝试一下相近的所有的主线版本 +（5.6、5.7 和 5.8）来检查它是什么时候出现的。除非你想在一个稳定版或长期支持 +内核中找到一个回归，否则要避免测试那些编号有三段的版本（5.6.12、5.7.8），因 +为那会使结果难以解释，可能会让你的测试变得无用。一旦你找到了引入回归的主要 +版本，就可以放心地继续报告了。但请记住：在不知道罪魁祸首的情况下，开发人员 +是否能够提供帮助取决于手头的问题。有时他们可能会从报告中确认是什么出现了问 +题，并能修复它；有时他们可能无法提供帮助，除非你进行二分。 + +当处理回归问题时，请确保你所面临的问题真的是由内核引起的，而不是由其他东西 +引起的，如上文所述。 + +在整个过程中，请记住：只有当旧内核和新内核的配置相似时，问题才算回归。最好 +的方法是：把配置文件（``.config``）从旧的工作内核直接复制到你尝试的每个新内 +核版本。之后运行 ``make oldnoconfig`` 来调整它以适应新版本的需要，而不启用 +任何新的功能，因为那些功能也可能导致回归。 + + +撰写并发送报告 +--------------- + + *通过详细描述问题来开始编写报告。记得包括以下条目：您为复现而安装的最新 + 内核版本、使用的Linux发行版以及关于如何复现该问题的说明。如果可能，将内 + 核构建配置（.config）和 ``dmesg`` 的输出放在网上的某个地方，并链接到它。 + 包含或上传所有其他可能相关的信息，如Oops的输出/截图或来自 ``lspci`` + 的输出。一旦你写完了这个主要部分，请在上方插入一个正常长度的段落快速概 + 述问题和影响。再在此之上添加一个简单描述问题的句子，以得到人们的阅读。 + 现在给出一个更短的描述性标题或主题。然后就可以像MAINTAINERS文件告诉你的 + 那样发送或提交报告了，除非你在处理一个“高优先级问题”：它们需要按照下面 + “高优先级问题的特殊处理”所述特别关照。* + +现在你已经准备好了一切，是时候写你的报告了。上文前言中链接的三篇文档对如何 +写报告做了部分解释。这就是为什么本文将只提到一些基本的内容以及 Linux 内核特 +有的东西。 + +有一点是符合这两类的：你的报告中最关键的部分是标题/主题、第一句话和第一段。 +开发者经常会收到许多邮件。因此，他们往往只是花几秒钟的时间浏览一下邮件，然 +后再决定继续下一封或仔细查看。因此，你报告的开头越好，有人研究并帮助你的机 +会就越大。这就是为什么你应该暂时忽略他们，先写出详细的报告。;-) + +每份报告都应提及的事项 +~~~~~~~~~~~~~~~~~~~~~~~~ + +详细描述你的问题是如何发生在你安装的新纯净内核上的。试着包含你之前写的和优 +化过的分步说明，概述你和其他人如何重现这个问题；在极少数无法重现的情况下， +尽量描述你做了什么来触发它。 + +还应包括其他人为了解该问题及其环境而可能需要的所有相关信息。实际需要的东西 +在很大程度上取决于具体问题，但有些事项你总是应该包括在内： + + * ``cat /proc/version`` 的输出，其中包含 Linux 内核版本号和构建时的编译器。 + + * 机器正在运行的 Linux 发行版（ ``hostnamectl | grep “Operating System“`` ） + + * CPU 和操作系统的架构（ ``uname -mi`` ） + + * 如果您正在处理回归，并进行了二分，请提及导致回归的变更的主题和提交ID。 + +许多情况下，让读你报告的人多了解两件事也是明智之举： + + * 用于构建 Linux 内核的配置（“.config”文件） + + * 内核的信息，你从 ``dmesg`` 得到的信息写到一个文件里。确保它以像“Linux + version 5.8-1 (foobar@example.com) (gcc (GCC) 10.2.1, GNU ld version + 2.34) #1 SMP Mon Aug 3 14:54:37 UTC 2020”这样的行开始，如果没有，那么第 + 一次启动阶段的重要信息已经被丢弃了。在这种情况下，可以考虑使用 + ``journalctl -b 0 -k`` ；或者你也可以重启，重现这个问题，然后调用 + ``dmesg`` 。 + +这两个文件很大，所以直接把它们放到你的报告中是个坏主意。如果你是在缺陷跟踪 +器中提交问题，那么将它们附加到工单中。如果你通过邮件报告问题，不要用附件附 +上它们，因为那会使邮件变得太大，可以按下列之一做： + + * 将文件上传到某个公开的地方（你的网站，公共文件粘贴服务，在 + `bugzilla.kernel.org <https://bugzilla.kernel.org/>`_ 上创建的工单……）， + 并在你的报告中放上链接。理想情况下请使用允许这些文件保存很多年的地方，因 + 为它们可能在很多年后对别人有用；例如 5 年或 10 年后，一个开发者正在修改 + 一些代码，而这些代码正是为了修复你的问题。 + + * 把文件放在一边，然后说明你会在他人回复时再单独发送。只要记得报告发出去后， + 真正做到这一点就可以了。;-) + +提供这些东西可能是明智的 +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +根据问题的不同，你可能需要提供更多的背景数据。这里有一些关于提供什么比较好 +的建议： + + * 如果你处理的是内核的“warning”、“OOPS”或“panic”，请包含它。如果你不能复制 + 粘贴它，试着用netconsole网络终端远程跟踪或者至少拍一张屏幕的照片。 + + * 如果问题可能与你的电脑硬件有关，请说明你使用的是什么系统。例如，如果你的 + 显卡有问题，请提及它的制造商，显卡的型号，以及使用的芯片。如果是笔记本电 + 脑，请提及它的型号名称，但尽量确保意义明确。例如“戴尔 XPS 13”就不很明确， + 因为它可能是 2012 年的那款，那款除了看起来和现在销售的没有什么不同之外， + 两者没有任何共同之处。因此，在这种情况下，要加上准确的型号，例如 2019 + 年内推出的 XPS 13 型号为“9380”或“7390”。像“联想 Thinkpad T590”这样的名字 + 也有些含糊不清：这款笔记本有带独立显卡和不带的子型号，所以要尽量找到准确 + 的型号名称或注明主要部件。 + + * 说明正在使用的相关软件。如果你在加载模块时遇到了问题，你要说明正在使用的 + kmod、systemd 和 udev 的版本。如果其中一个 DRM 驱动出现问题，你要说明 + libdrm 和 Mesa 的版本；还要说明你的 Wayland 合成器或 X-Server 及其驱动。 + 如果你有文件系统问题，请注明相应的文件系统实用程序的版本（e2fsprogs, + btrfs-progs, xfsprogs……）。 + + * 从内核中收集可能有用的额外信息。例如， ``lspci -nn`` 的输出可以帮助别人 + 识别你使用的硬件。如果你的硬件有问题，你甚至可以给出 ``sudo lspci -vvv`` + 的结果，因为它提供了组件是如何配置的信息。对于一些问题，可能最好包含 + ``/proc/cpuinfo`` ， ``/proc/ioports`` ， ``/proc/iomem`` ， + ``/proc/modules`` 或 ``/proc/scsi/scsi`` 等文件的内容。一些子系统还提 + 供了收集相关信息的工具。 ``alsa-info.sh`` `就是这样一个工具，它是音频/声 + 音子系统开发者提供的 <https://www.alsa-project.org/wiki/AlsaInfo>`_ 。 + +这些例子应该会给你一些知识点，让你知道附上什么数据可能是明智的，但你自己也 +要想一想，哪些数据对别人会有帮助。不要太担心忘记一些东西，因为开发人员会要 +求提供他们需要的额外细节。但从一开始就把所有重要的东西都提供出来，会增加别 +人仔细查看的机会。 + + +重要部分：报告的开头 +~~~~~~~~~~~~~~~~~~~~~~ + +现在你已经准备好了报告的详细部分，让我们进入最重要的部分：开头几句。现在到 +报告的最前面，在你刚才写的部分之前加上类似“The detailed description:”（详细 +描述）这样的内容，并在最前面插入两个新行。现在写一个正常长度的段落，大致概 +述这个问题。去掉所有枯燥的细节，把重点放在读者需要知道的关键部分，以让人了 +解这是怎么回事；如果你认为这个缺陷影响了很多用户，就提一下这点来吸引大家关 +注。 + +做好这一点后，在顶部再插入两行，写一句话的摘要，快速解释报告的内容。之后你 +要更加抽象，为报告写一个更短的主题/标题。 + +现在你已经写好了这部分，请花点时间来优化它，因为它是你的报告中最重要的部分： +很多人会先读这部分，然后才会决定是否值得花时间阅读其他部分。 + +现在就像 :ref:`MAINTAINERS <maintainers>` 维护者文件告诉你的那样发送或提交 +报告，除非它是前面概述的那些“高优先级问题”之一：在这种情况下，请先阅读下一 +小节，然后再发送报告。 + +高优先级问题的特殊处理 +~~~~~~~~~~~~~~~~~~~~~~~~ + +高优先级问题的报告需要特殊处理。 + +**非常严重的缺陷** ：确保在主题或工单标题以及第一段中明显标出 severeness +（非常严重的）。 + +**回归** ：如果问题是一个回归，请在邮件的主题或缺陷跟踪器的标题中添加 +[REGRESSION]。如果您没有进行二分，请至少注明您测试的最新主线版本（比如 5.7） +和出现问题的最新版本（比如 5.8）。如果您成功地进行了二分，请注明导致回归 +的提交ID和主题。也请添加该变更的作者到你的报告中；如果您需要将您的缺陷提交 +到缺陷跟踪器中，请将报告以私人邮件的形式转发给他，并注明报告提交地点。 + +**安全问题** ：对于这种问题，你将必须评估：如果细节被公开披露，是否会对其他 +用户产生短期风险。如果不会，只需按照所述继续报告问题。如果有此风险，你需要 +稍微调整一下报告流程。 + + * 如果 MAINTAINERS 文件指示您通过邮件报告问题，请不要抄送任何公共邮件列表。 + + * 如果你应该在缺陷跟踪器中提交问题，请确保将工单标记为“私有”或“安全问题”。 + 如果缺陷跟踪器没有提供保持报告私密性的方法，那就别想了，把你的报告以私人 + 邮件的形式发送给维护者吧。 + +在这两种情况下，都一定要将报告发到 MAINTAINERS 文件中“安全联络”部分列出的 +地址。理想的情况是在发送报告的时候直接抄送他们。如果您在缺陷跟踪器中提交了 +报告，请将报告的文本转发到这些地址；但请在报告的顶部加上注释，表明您提交了 +报告，并附上工单链接。 + +更多信息请参见“Documentation/translations/zh_CN/admin-guide/security-bugs.rst”。 + + +发布报告后的责任 +------------------ + + *等待别人的反应，继续推进事情，直到你能够接受这样或那样的结果。因此，请 + 公开和及时地回应任何询问。测试提出的修复。积极地测试：至少重新测试每个 + 新主线版本的首个候选版本（RC），并报告你的结果。如果出现拖延，就友好地 + 提醒一下。如果你没有得到任何帮助或者未能满意，请试着自己帮助自己。* + +如果你的报告非常优秀，而且你真的很幸运，那么某个开发者可能会立即发现导致问 +题的原因；然后他们可能会写一个补丁来修复、测试它，并直接发送给主线集成，同 +时标记它以便以后回溯到需要它的稳定版和长期支持内核。那么你需要做的就是回复 +一句“Thank you very much”（非常感谢），然后在发布后换上修复好的版本。 + +但这种理想状况很少发生。这就是为什么你把报告拿出来之后工作才开始。你要做的 +事情要视情况而定，但通常会是下面列出的事情。但在深入研究细节之前，这里有几 +件重要的事情，你需要记住这部分的过程。 + + +关于进一步互动的一般建议 +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +**总是公开回复** ：当你在缺陷跟踪器中提交问题时，一定要在那里回复，不要私下 +联系任何开发者。对于邮件报告，在回复您收到的任何邮件时，总是使用“全部回复” +功能。这包括带有任何你可能想要添加到你的报告中的额外数据的邮件：进入邮件应 +用程序“已发送”文件夹，并在邮件上使用“全部回复”来回复报告。这种方法可以确保 +公共邮件列表和其他所有参与者都能及时了解情况；它还能保持邮件线程的完整性， +这对于邮件列表将所有相关邮件归为一类是非常重要的。 + +只有两种情况不适合在缺陷跟踪器或“全部回复”中发表评论： + + * 有人让你私下发东西。 + + * 你被告知要发送一些东西，但注意到其中包含需要保密的敏感信息。在这种情况下， + 可以私下发送给要求发送的开发者。但要在工单或邮件中注明你是这么做的，这 + 样其他人就知道你尊重了这个要求。 + +**在请求解释或帮助之前先研究一下** ：在这部分过程中，有人可能会告诉你用尚未 +掌握的技能做一些事情。例如你可能会被要求使用一些你从未听说过的测试工具；或 +者你可能会被要求在 Linux 内核源代码上应用一个补丁来测试它是否有帮助。在某些 +情况下，发个回复询问如何做就可以了。但在走这条路之前，尽量通过在互联网上搜 +索自行找到答案；或者考虑在其他地方询问建议。比如询问朋友，或者到你平时常去 +的聊天室或论坛发帖咨询。 + +**要有耐心** ：如果你真的很幸运，你可能会在几个小时内收到对你的报告的答复。 +但大多数情况下会花费更多的时间，因为维护者分散在全球各地，因此可能在不同的 +时区——在那里他们已经享受着远离键盘的夜晚。 + +一般来说，内核开发者需要一到五个工作日来回复报告。有时会花费更长的时间，因 +为他们可能正忙于合并窗口、其他工作、参加开发者会议，或者只是在享受一个漫长 +的暑假。 + +“高优先级的问题”（见上面的解释）例外：维护者应该尽快解决这些问题；这就是为 +什么你应该最多等待一个星期（如果是紧急的事情，则只需两天），然后再发送友好 +的提醒。 + +有时维护者可能没有及时回复；有时候可能会出现分歧，例如一个问题是否符合回归 +的条件。在这种情况下，在邮件列表上提出你的顾虑，并请求其他人公开或私下回复 +如何继续推进。如果失败了，可能应该让更高级别的维护者介入。如果是 WiFi 驱动， +那就是无线维护者；如果没有更高级别的维护者，或者其他一切努力都失败了，那 +这可能是一种罕见的、可以让 Linus Torvalds 参与进来的情况。 + +**主动测试** ：每当一个新的主线内核版本的第一个预发布版本（rc1）发布的时候， +去检查一下这个问题是否得到了解决，或者是否有什么重要的变化。在工单中或在 +回复报告的邮件中提及结果（确保所有参与讨论的人都被抄送）。这将表明你的承诺 +和你愿意帮忙。如果问题持续存在，它也会提醒开发者确保他们不会忘记它。其他一 +些不定期的重新测试（例如用rc3、rc5 和最终版本）也是一个好主意，但只有在相关 +的东西发生变化或者你正在写什么东西的时候才报告你的结果。 + +这些些常规的事情就不说了，我们来谈谈报告后如何帮助解决问题的细节。 + +查询和测试请求 +~~~~~~~~~~~~~~~ + +如果你的报告得到了回复则需履行以下责任： + +**检查与你打交道的人** ：大多数情况下，会是维护者或特定代码区域的开发人员对 +你的报告做出回应。但由于问题通常是公开报告的，所以回复的可能是任何人——包括 +那些想要帮忙的人，但最后可能会用他们的问题或请求引导你完全偏离轨道。这很少 +发生，但这是快速上网搜搜看你正在与谁互动是明智之举的许多原因之一。通过这样 +做，你也可以知道你的报告是否被正确的人听到，因为如果讨论没有导致满意的问题 +解决方案而淡出，之后可能需要提醒维护者（见下文）。 + +**查询数据** ：通常你会被要求测试一些东西或提供更多细节。尽快提供所要求的信 +息，因为你已经得到了可能会帮助你的人的注意，你等待的时间越长就有越可能失去 +关注；如果你不在数个工作日内提供信息，甚至可能出现这种结果。 + +**测试请求** ：当你被要求测试一个诊断补丁或可能的修复时，也要尽量及时测试。 +但要做得恰当，一定不要急于求成：混淆事情很容易发生，这会给所有人带来许多困 +惑。例如一个常见的错误是以为应用了一个带修复的建议补丁，但事实上并没有。即 +使是有经验的测试人员也会偶尔发生这样的事情，但当有修复的内核和没有修复的内 +核表现得一样时，他们大多时候会注意到。 + +当没有任何实质性进展时该怎么办 +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +有些报告不会得到负有相关责任的 Linux 内核开发者的任何反应；或者围绕这个问题 +的讨论有所发展，但渐渐淡出，没有任何实质内容产出。 + +在这种情况下，要等两个星期（最好是三个星期）后再发出友好的提醒：也许当你的 +报告到达时，维护者刚刚离开键盘一段时间，或者有更重要的事情要处理。在写提醒 +信的时候，要善意地问一下，是否还需要你这边提供什么来让事情推进下去。如果报 +告是通过邮件发出来的，那就在邮件的第一行回复你的初始邮件（见上文），其中包 +括下方的原始报告的完整引用：这是少数几种情况下，这样的“TOFU”（Text Over, +Fullquote Under文字在上，完整引用在下）是正确的做法，因为这样所有的收件人都 +会以适当的顺序立即让细节到手头上来。 + +在提醒之后，再等三周的回复。如果你仍然没有得到适当的反馈，你首先应该重新考 +虑你的方法。你是否可能尝试接触了错误的人？是不是报告也许令人反感或者太混乱， +以至于人们决定完全远离它？排除这些因素的最好方法是：把报告给一两个熟悉 +FLOSS 问题报告的人看，询问他们的意见。同时征求他们关于如何继续推进的建议。 +这可能意味着：准备一份更好的报告，让这些人在你发出去之前对它进行审查。这样 +的方法完全可以；只需说明这是关于这个问题的第二份改进的报告，并附上第一份报 +告的链接。 + +如果报告是恰当的，你可以发送第二封提醒信；在其中询问为什么报告没有得到任何 +回复。第二封提醒邮件的好时机是在新 Linux 内核版本的首个预发布版本（'rc1'） +发布后不久，因为无论如何你都应该在那个时候重新测试并提供状态更新（见上文）。 + +如果第二次提醒的结果又在一周内没有任何反应，可以尝试联系上级维护者询问意见： +即使再忙的维护者在这时候也至少应该发过某种确认。 + +记住要做好失望的准备：理想状况下维护者最好对每一个问题报告做出回应，但他们 +只有义务解决之前列出的“高优先级问题”。所以，如果你得到的回复是“谢谢你的报告， +我目前有更重要的问题要处理，在可预见的未来没有时间去研究这个问题”，那请不 +要太沮丧。 + +也有可能在缺陷跟踪器或列表中进行了一些讨论之后，什么都没有发生，提醒也无助 +于激励大家进行修复。这种情况可能是毁灭性的，但在 Linux 内核开发中确实会发生。 +这些和其他得不到帮助的原因在本文结尾处的“为什么有些问题在被报告后没有得到 +任何回应或者仍然没有修复”中进行了解释。 + +如果你没有得到任何帮助或问题最终没有得到解决，不要沮丧：Linux 内核是 FLOSS， +因此你仍然可以自己帮助自己。例如，你可以试着找到其他受影响的人，和他们一 +起合作来解决这个问题。这样的团队可以一起准备一份新的报告，提到团队有多少人， +为什么你们认为这是应该得到解决的事情。也许你们还可以一起缩小确切原因或引 +入回归的变化，这往往会使修复更容易。而且如果运气好的话，团队中可能会有懂点 +编程的人，也许能写出一个修复方案。 + + + +“报告稳定版和长期支持内核线的回归”的参考 +------------------------------------------ + +本小节提供了在稳定版和长期支持内核线中面对回归时需要执行的步骤的详细信息。 + +确保特定版本线仍然受支持 +~~~~~~~~~~~~~~~~~~~~~~~~~ + + *检查内核开发人员是否仍然维护你关心的Linux内核版本线：去 kernel.org 的 + 首页，确保此特定版本线的最新版没有“[EOL]”标记。* + +大多数内核版本线只支持三个月左右，因为延长维护时间会带来相当多的工作。因此， +每年只会选择一个版本来支持至少两年（通常是六年）。这就是为什么你需要检查 +内核开发者是否还支持你关心的版本线。 + +注意，如果 `kernel.org <https://kernel.org/>`_ 在首页上列出了两个“稳定”版本， +你应该考虑切换到较新的版本，而忘掉较旧的版本：对它的支持可能很快就会结束。 +然后，它将被标记为“生命周期结束”（EOL）。达到这个程度的版本线仍然会在 +`kernel.org <https://kernel.org/>`_ 首页上被显示一两周，但不适合用于测试和 +报告。 + +搜索稳定版邮件列表 +~~~~~~~~~~~~~~~~~~~ + + *检查Linux稳定版邮件列表中的现有报告。* + +也许你所面临的问题已经被发现，并且已经或即将被修复。因此，请在 `Linux 稳定 +版邮件列表的档案 <https://lore.kernel.org/stable/>`_ 中搜索类似问题的报告。 +如果你找到任何匹配的问题，可以考虑加入讨论，除非修复工作已经完成并计划很快 +得到应用。 + +用最新版本复现问题 +~~~~~~~~~~~~~~~~~~~ + + *从特定的版本线安装最新版本作为纯净内核。确保这个内核没有被污染，并且仍 + 然存在问题，因为问题可能已经在那里被修复了。* + +在投入更多时间到这个过程中之前，你要检查这个问题是否在你关注的版本线的最新 +版本中已经得到了修复。这个内核需要是纯净的，在问题发生之前不应该被污染，正 +如上面已经在测试主线的过程中详细介绍过的一样。 + +您是否是第一次注意到供应商内核的回归？供应商的更改可能会发生变化。你需要重新 +检查排除来这个问题。当您从5.10.4-vendor.42更新到5.10.5-vendor.43时，记录损坏 +的信息。然后在测试了前一段中所述的最新5.10版本之后，检查Linux 5.10.4的普通版本 +是否也可以正常工作。如果问题在那里出现，那就不符合上游回归的条件，您需要切换 +回主逐步指南来报告问题。 + +报告回归 +~~~~~~~~~~ + + *向Linux稳定版邮件列表发送一个简短的问题报告(stable@vger.kernel.org)。 + 大致描述问题，并解释如何复现。讲清楚首个出现问题的版本和最后一个工作正常 + 的版本。然后等待进一步的指示。* + +当报告在稳定版或长期支持内核线内发生的回归（例如在从5.10.4更新到5.10.5时）， +一份简短的报告足以快速报告问题。因此只需要粗略的描述。 + +但是请注意，如果您能够指明引入问题的确切版本，这将对开发人员有很大帮助。因此 +如果有时间的话，请尝试使用普通内核找到该版本。让我们假设发行版发布Linux内核 +5.10.5到5.10.8的更新时发生了故障。那么按照上面的指示，去检查该版本线中的最新 +内核，比如5.10.9。如果问题出现，请尝试普通5.10.5，以确保供应商应用的补丁不会 +干扰。如果问题没有出现，那么尝试5.10.7，然后直到5.10.8或5.10.6（取决于结果） +找到第一个引入问题的版本。在报告中写明这一点，并指出5.10.9仍然存在故障。 + +前一段基本粗略地概述了“二分”方法。一旦报告出来，您可能会被要求做一个正确的 +报告，因为它允许精确地定位导致问题的确切更改（然后很容易被恢复以快速修复问题）。 +因此如果时间允许，考虑立即进行适当的二分。有关如何详细信息，请参阅“对回归的 +特别关照”部分和文档“Documentation/translations/zh_CN/admin-guide/bug-bisect.rst”。 + + +“报告仅在旧内核版本线中发生的问题”的参考 +---------------------------------------- + +本节详细介绍了如果无法用主线内核重现问题，但希望在旧版本线（又称稳定版内核和 +长期支持内核）中修复问题时需要采取的步骤。 + +有些修复太复杂 +~~~~~~~~~~~~~~~ + + *请做好准备，接下来的几个步骤可能无法在旧版本中解决问题：修复可能太大或 + 太冒险，无法移植到那里。* + +即使是微小的、看似明显的代码变化，有时也会带来新的、完全意想不到的问题。稳 +定版和长期支持内核的维护者非常清楚这一点，因此他们只对这些内核进行符合 +“Documentation/translations/zh_CN/process/stable-kernel-rules.rst”中所列出的 +规则的修改。 + +复杂或有风险的修改不符合条件，因此只能应用于主线。其他的修复很容易被回溯到 +最新的稳定版和长期支持内核，但是风险太大，无法集成到旧版内核中。所以要注意 +你所希望的修复可能是那些不会被回溯到你所关心的版本线的修复之一。在这种情况 +下，你将别无选择，要么忍受这个问题，要么切换到一个较新的 Linux 版本，除非你 +想自己把修复补丁应用到你的内核中。 + +通用准备 +~~~~~~~~~~ + + *执行上面“报告仅在旧内核版本线中发生的问题”一节中的前三个步骤。* + +您需要执行本指南另一节中已经描述的几个步骤。这些步骤将让您： + + * 检查内核开发人员是否仍然维护您关心的Linux内核版本行。 + + * 在Linux稳定邮件列表中搜索退出的报告。 + + * 检查最新版本。 + + +检查代码历史和搜索现有的讨论 +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + *在Linux内核版本控制系统中搜索修复主线问题的更改，因为它的提交消息可能 + 会告诉你修复是否已经计划好了支持。如果你没有找到，搜索适当的邮件列表， + 寻找讨论此类问题或同行评议可能修复的帖子；然后检查讨论是否认为修复不适 + 合支持。如果支持根本不被考虑，加入最新的讨论，询问是否有可能。* + +在许多情况下，你所处理的问题会发生在主线上，但已在主线上得到了解决。修正它 +的提交也需要被回溯才能解决这个问题。这就是为什么你要搜索它或任何相关讨论。 + + * 首先尝试在存放 Linux 内核源代码的 Git 仓库中找到修复。你可以通过 + `kernel.org 上的网页 + <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/>`_ + 或 `GitHub 上的镜像 <https://github.com/torvalds/linux>`_ 来实现；如果你 + 有一个本地克隆，你也可以在命令行用 ``git log --grep=<pattern>`` 来搜索。 + + 如果你找到了修复，请查看提交消息的尾部是否包含了类似这样的“稳定版标签”： + + Cc: <stable@vger.kernel.org> # 5.4+ + + 像上面这行，开发者标记了安全修复可以回传到 5.4 及以后的版本。大多数情况 + 下，它会在两周内被应用到那里，但有时需要更长的时间。 + + * 如果提交没有告诉你任何东西，或者你找不到修复，请再找找关于这个问题的讨论。 + 用你最喜欢的搜索引擎搜索网络，以及 `Linux kernel developers mailing + list 内核开发者邮件列表 <https://lore.kernel.org/lkml/>`_ 的档案。也可以 + 阅读上面的 `定位导致问题的内核区域` 一节，然后按照说明找到导致问题的子系 + 统：它的缺陷跟踪器或邮件列表存档中可能有你要找的答案。 + + * 如果你看到了一个计划的修复，请按上所述在版本控制系统中搜索它，因为提交可 + 能会告诉你是否可以进行回溯。 + + * 检查讨论中是否有任何迹象表明，该修复程序可能风险太大，无法回溯到你关心 + 的版本线。如果是这样的话，你必须忍受这个问题，或者切换到应用了修复的内 + 核版本线。 + + * 如果修复的问题未包含稳定版标签，并且没有讨论过回溯问题，请加入讨论：如 + 果合适的话，请提及你所面对的问题的版本，以及你希望看到它被修复。 + + +请求建议 +~~~~~~~~~ + + *前面的步骤之一应该会给出一个解决方案。如果仍未能成功，请向可能引起问题 + 的子系统的维护人员询问建议；抄送特定子系统的邮件列表以及稳定版邮件列表。* + +如果前面的三个步骤都没有让你更接近解决方案，那么只剩下一个选择：请求建议。 +在你发给可能是问题根源的子系统的维护者的邮件中这样做；抄送子系统的邮件列表 +以及稳定版邮件列表（stable@vger.kernel.org）。 + + +为什么有些问题在报告后没有任何回应或仍未解决？ +=============================================== + +当向 Linux 开发者报告问题时，要注意只有“高优先级的问题”（回归、安全问题、严 +重问题）才一定会得到解决。如果维护者或其他人都失败了，Linus Torvalds 他自己 +会确保这一点。他们和其他内核开发者也会解决很多其他问题。但是要知道，有时他 +们也会不能或不愿帮忙；有时甚至没有人发报告给他们。 + +最好的解释就是那些内核开发者常常是在业余时间为 Linux 内核做出贡献。内核中的 +不少驱动程序都是由这样的程序员编写的，往往只是因为他们想让自己的硬件可以在 +自己喜欢的操作系统上使用。 + +这些程序员大多数时候会很乐意修复别人报告的问题。但是没有人可以强迫他们这样 +做，因为他们是自愿贡献的。 + +还有一些情况下，这些开发者真的很想解决一个问题，但却不能解决：有时他们缺乏 +硬件编程文档来解决问题。这种情况往往由于公开的文档太简陋，或者驱动程序是通 +过逆向工程编写的。 + +业余开发者迟早也会不再关心某驱动。也许他们的测试硬件坏了，被更高级的玩意取 +代了，或者是太老了以至于只能在计算机博物馆里找到。有时开发者根本就不关心他 +们的代码和 Linux 了，因为在他们的生活中一些不同的东西变得更重要了。在某些情 +况下，没有人愿意接手维护者的工作——也没有人可以被强迫，因为对 Linux 内核的贡 +献是自愿的。然而被遗弃的驱动程序仍然存在于内核中：它们对人们仍然有用，删除 +它们可能导致回归。 + +对于那些为 Linux 内核工作而获得报酬的开发者来说，情况并没有什么不同。这些人 +现在贡献了大部分的变更。但是他们的雇主迟早也会停止关注他们的代码或者让程序 +员专注于其他事情。例如，硬件厂商主要通过销售新硬件来赚钱；因此，他们中的不 +少人并没有投入太多时间和精力来维护他们多年前就停止销售的东西的 Linux 内核驱 +动。企业级 Linux 发行商往往持续维护的时间比较长，但在新版本中往往会把对老旧 +和稀有硬件的支持放在一边，以限制范围。一旦公司抛弃了一些代码，往往由业余贡 +献者接手，但正如上面提到的：他们迟早也会放下代码。 + +优先级是一些问题没有被修复的另一个原因，因为维护者相当多的时候是被迫设置这 +些优先级的，因为在 Linux 上工作的时间是有限的。对于业余时间或者雇主给予他们 +的开发人员用于上游内核维护工作的时间也是如此。有时维护人员也会被报告淹没， +即使一个驱动程序几乎完美地工作。为了不被完全缠住，程序员可能别无选择，只能 +对问题报告进行优先级排序而拒绝其中的一些报告。 + +不过这些都不用太过担心，很多驱动都有积极的维护者，他们对尽可能多的解决问题 +相当感兴趣。 + + +结束语 +======= + +与其他免费/自由&开源软件（Free/Libre & Open Source Software，FLOSS）相比， +向 Linux 内核开发者报告问题是很难的：这个文档的长度和复杂性以及字里行间的内 +涵都说明了这一点。但目前就是这样了。这篇文字的主要作者希望通过记录现状来为 +以后改善这种状况打下一些基础。 diff --git a/Documentation/translations/zh_CN/admin-guide/security-bugs.rst

+尽管我们倾向于在未公开缺陷的修复可用时即发布补丁，但应报告者或受影响方的请求， +这可能会被推迟到发布过程开始后的7日内，如果根据缺陷的严重性需要更多的时间， +则可额外延长到14天。推迟发布修复的唯一有效原因是为了适应QA的逻辑和需要发布 +协调的大规模部署。 + +虽然可能与受信任的个人共享受限信息以开发修复，但未经报告者许可，此类信息不会 +与修复程序一起发布或发布在任何其他披露渠道上。这包括但不限于原始错误报告和 +后续讨论（如有）、漏洞、CVE信息或报告者的身份。 + +换句话说，我们唯一感兴趣的是修复缺陷。提交给安全列表的所有其他资料以及对报告 +的任何后续讨论，即使在解除限制之后，也将永久保密。 + +协调 +------ + +对敏感缺陷（例如那些可能导致权限提升的缺陷）的修复可能需要与私有邮件列表 +<linux-distros@vs.openwall.org>进行协调，以便分发供应商做好准备，在公开披露 +上游补丁时发布一个已修复的内核。发行版将需要一些时间来测试建议的补丁，通常 +会要求至少几天的限制，而供应商更新发布更倾向于周二至周四。若合适，安全团队 +可以协助这种协调，或者报告者可以从一开始就包括linux发行版。在这种情况下，请 +记住在电子邮件主题行前面加上“[vs]”，如linux发行版wiki中所述： +<http://oss-security.openwall.org/wiki/mailing-lists/distros#how-to-use-the-lists>。 + +CVE分配 +-------- + +安全团队通常不分配CVE，我们也不需要它们来进行报告或修复，因为这会使过程不必 +要的复杂化，并可能耽误缺陷处理。如果报告者希望在公开披露之前分配一个CVE编号， +他们需要联系上述的私有linux-distros列表。当在提供补丁之前已有这样的CVE编号时， +如报告者愿意，最好在提交消息中提及它。 + +保密协议 +--------- + +Linux内核安全团队不是一个正式的机构实体，因此无法签订任何保密协议。 diff --git

+（tainted）”的。不用太过担心，大多数情况下运行受污染的内核没有问题；这些信息 +主要在有人想调查某个问题时才有意义的，因为问题的真正原因可能是导致内核受污染 +的事件。这就是为什么来自受污染内核的缺陷报告常常被开发人员忽略，因此请尝试用 +未受污染的内核重现问题。 + +请注意，即使在您消除导致污染的原因（亦即卸载专有内核模块）之后，内核仍将保持 +污染状态，以表示内核仍然不可信。这也是为什么内核在注意到内部问题（“kernel +bug”）、可恢复错误（“kernel oops”）或不可恢复错误（“kernel panic”）时会打印 +受污染状态，并将有关此的调试信息写入日志 ``dmesg`` 输出。也可以通过 +``/proc/`` 中的文件在运行时检查受污染的状态。 + + +BUG、Oops或Panics消息中的污染标志 +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +在顶部以“CPU:”开头的一行中可以找到受污染的状态；内核是否受到污染和原因会显示 +在进程ID（“PID:”）和触发事件命令的缩写名称（“Comm:”）之后:: + + BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 +

+如果内核在事件发生时没有被污染，您将在那里看到“Not-tainted:”；如果被污染，那 +么它将是“Tainted:”以及字母或空格。在上面的例子中，它看起来是这样的:: + + Tainted: P W O + +下表解释了这些字符的含义。在本例中，由于加载了专有模块（ ``P`` ），出现了 +警告（ ``W`` ），并且加载了外部构建的模块（ ``O`` ），所以内核早些时候受到 +了污染。要解码其他字符，请使用下表。 + + +解码运行时的污染状态 +~~~~~~~~~~~~~~~~~~~~~ + +在运行时，您可以通过读取 ``cat /proc/sys/kernel/tainted`` 来查询受污染状态。 +如果返回 ``0`` ，则内核没有受到污染；任何其他数字都表示受到污染的原因。解码 +这个数字的最简单方法是使用脚本 ``tools/debugging/kernel-chktaint`` ，您的 +发行版可能会将其作为名为 ``linux-tools`` 或 ``kernel-tools`` 的包的一部分提 +供；如果没有，您可以从 +`git.kernel.org <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/tools/debugging/kernel-chktaint>`_ +网站下载此脚本并用 ``sh kernel-chktaint`` 执行，它会在上面引用的日志中有类似 +语句的机器上打印这样的内容:: + + Kernel is Tainted

+Linux内核代码已被重写以使用Unicode来将字符映射到字体。下载一个Unicode到字体 +（Unicode-to-font）表，八位字符集与UTF-8模式都将改用此字体来显示。 + +这微妙地改变了八位字符表的语义。现在的四个字符表是： + +=============== =============================== ================ +映射代号

( U +USER_MAP User defined ESC ( K +=============== =============================== ================ + +特别是 ESC ( U 不再是“直通字体”，因为字体可能与IBM字符集完全不同。 +例如，即使加载了一个Latin-1字体，也允许使用块图形（block graphics）。 + +请注意，尽管这些代码与ISO 2022类似，但这些代码及其用途都与ISO 2022不匹配； +Linux有两个八位代码（G0和G1），而ISO 2022有四个七位代码（G0-G3）。 + +根据Unicode标准/ISO 10646，U+F000到U+F8FF被保留用于操作系统范围内的分配 +（Unicode标准将其称为“团体区域（Corporate Zone）”，因为这对于Linux是不准确 +的，所以我们称之为“Linux区域”）。选择U+F000作为起点，因为它允许直接映射 +区域以2的大倍数开始（以防需要1024或2048个字符的字体）。这就留下U+E000到 +U+EFFF作为最终用户区。 + +[v1.2]：Unicodes范围从U+F000到U+F7FF已经被硬编码为直接映射到加载的字体， +绕过了翻译表。用户定义的映射现在默认为U+F000到U+F0FF，模拟前述行为。实际上， +此范围可能较短；例如，vgacon只能处理256字符（U+F000..U+F0FF）或512字符 +（U+F000..U+F1FF）字体。 + +Linux 区域中定义的实际字符 +--------------------------- + +此外，还定义了Unicode

中断号映射库 +======================= + +目前Linux内核的设计使用了一个巨大的数字空间，每个独立的IRQ源都被分配了一个不 +同的数字。 +当只有一个中断控制器时，这很简单，但在有多个中断控制器的系统中，内核必须确保每 +个中断控制器都能得到非重复的Linux IRQ号（数字）分配。 + +注册为唯一的irqchips的中断控制器编号呈现出上升的趋势：例如GPIO控制器等不同 +种类的子驱动程序通过将其中断处理程序建模为irqchips，即实际上是级联中断控制器， +避免了重新实现与IRQ核心系统相同的回调机制。 + +在这里，中断号与硬件中断号离散了所有种类的对应关系：而在过去，IRQ号可以选择， +使它们与硬件IRQ线进入根中断控制器（即实际向CPU发射中断线的组件）相匹配，现 +在这个编号仅仅是一个数字。 + +出于这个原因，我们需要一种机制将控制器本地中断号（即硬件irq编号）与Linux IRQ +号分开。 + +irq_alloc_desc*() 和 irq_free_desc*() API 提供了对irq号的分配，但它们不 +提供任何对控制器本地IRQ(hwirq)号到Linux IRQ号空间的反向映射的支持。 + +irq_domain 库在 irq_alloc_desc*() API 的基础上增加了 hwirq 和 IRQ 号码 +之间的映射。 相比于中断控制器驱动开放编码自己的反向映射方案，我们更喜欢用 +irq_domain来管理映射。 + +irq_domain还实现了从抽象的irq_fwspec结构体到hwirq号的转换（到目前为止是 +Device Tree和ACPI GSI），并且可以很容易地扩展以支持其它IRQ拓扑数据源。 + +irq_domain的用法 +================ + +中断控制器驱动程序通过以下方式创建并注册一个irq_domain。调用 +irq_domain_add_*() 或 irq_domain_create_*()函数之一（每个映射方法都有不 +同的分配器函数，后面会详细介绍）。 函数成功后会返回一个指向irq_domain的指针。 +调用者必须向分配器函数提供一个irq_domain_ops结构体。 + +在大多数情况下，irq_domain在开始时是空的，没有任何hwirq和IRQ号之间的映射。 +通过调用irq_create_mapping()将映射添加到irq_domain中，该函数接受 +irq_domain和一个hwirq号作为参数。 如果hwirq的映射还不存在，那么它将分配 +一个新的Linux irq_desc，将其与hwirq关联起来，并调用.map()回调，这样驱动 +程序就可以执行任何必要的硬件设置。 + +当接收到一个中断时，应该使用irq_find_mapping()函数从hwirq号中找到 +Linux IRQ号。 + +在调用irq_find_mapping()之前，至少要调用一次irq_create_mapping()函数， +以免描述符不能被分配。 + +如果驱动程序有Linux的IRQ号或irq_data指针，并且需要知道相关的hwirq号（比 +如在irq_chip回调中），那么可以直接从irq_data->hwirq中获得。 + +irq_domain映射的类型 +==================== + +从hwirq到Linux irq的反向映射有几种机制，每种机制使用不同的分配函数。应该 +使用哪种反向映射类型取决于用例。 下面介绍每一种反向映射类型： + +线性映射 +-------- + +:: + + irq_domain_add_linear() + irq_domain_create_linear() + +线性反向映射维护了一个固定大小的表，该表以hwirq号为索引。 当一个hwirq被映射 +时，会给hwirq分配一个irq_desc，并将irq号存储在表中。 + +当最大的hwirq号固定且数量相对较少时，线性图是一个很好的选择（~<256）。 这种 +映射的优点是固定时间查找IRQ号，而且irq_descs只分配给在用的IRQ。 缺点是该表 +必须尽可能大的hwirq号。 + +irq_domain_add_linear()和irq_domain_create_linear()在功能上是等价的， +除了第一个参数不同--前者接受一个Open Firmware特定的 'struct device_node' 而 +后者接受一个更通用的抽象 'struct fwnode_handle' 。 + +大多数驱动应该使用线性映射 + +树状映射 +-------- + +:: + + irq_domain_add_tree() + irq_domain_create_tree() + +irq_domain维护着从hwirq号到Linux IRQ的radix的树状映射。 当一个hwirq被映射时， +一个irq_desc被分配，hwirq被用作radix树的查找键。 + +如果hwirq号可以非常大，树状映射是一个很好的选择，因为它不需要分配一个和最大hwirq +号一样大的表。 缺点是，hwirq到IRQ号的查找取决于表中有多少条目。 + +irq_domain_add_tree()和irq_domain_create_tree()在功能上是等价的，除了第一 +个参数不同——前者接受一个Open Firmware特定的 'struct device_node' ，而后者接受 +一个更通用的抽象 'struct fwnode_handle' 。 + +很少有驱动应该需要这个映射。 + +无映射 +------ + +:: + + irq_domain_add_nomap() + +当硬件中的hwirq号是可编程的时候，就可以采用无映射类型。 在这种情况下，最好将 +Linux IRQ号编入硬件本身，这样就不需要映射了。 调用irq_create_direct_mapping() +会分配一个Linux IRQ号，并调用.map()回调，这样驱动就可以将Linux IRQ号编入硬件中。 + +大多数驱动程序不能使用这个映射。 + +传统映射类型 +------------ + +:: + + irq_domain_add_simple() + irq_domain_add_legacy() + irq_domain_add_legacy_isa() + irq_domain_create_simple() + irq_domain_create_legacy() + +传统映射是已经为 hwirqs 分配了一系列 irq_descs 的驱动程序的特殊情况。 当驱动程 +序不能立即转换为使用线性映射时，就会使用它。 例如，许多嵌入式系统板卡支持文件使用 +一组用于IRQ号的定义（#define），这些定义被传递给struct设备注册。 在这种情况下， +不能动态分配Linux IRQ号，应该使用传统映射。 + +传统映射假设已经为控制器分配了一个连续的IRQ号范围，并且可以通过向hwirq号添加一 +个固定的偏移来计算IRQ号，反之亦然。 缺点是需要中断控制器管理IRQ分配，并且需要为每 +个hwirq分配一个irq_desc，即使它没有被使用。 + +只有在必须支持固定的IRQ映射时，才应使用传统映射。 例如，ISA控制器将使用传统映射来 +映射Linux IRQ 0-15，这样现有的ISA驱动程序就能得到正确的IRQ号。 + +大多数使用传统映射的用户应该使用irq_domain_add_simple()或 +irq_domain_create_simple()，只有在系统提供IRQ范围时才会使用传统域，否则将使用 +线性域映射。这个调用的语义是这样的：如果指定了一个IRQ范围，那么 描述符将被即时分配 +给它，如果没有范围被分配，它将不会执行 irq_domain_add_linear() 或 +irq_domain_create_linear()，这意味着 *no* irq 描述符将被分配。 + +一个简单域的典型用例是，irqchip供应商同时支持动态和静态IRQ分配。 + +为了避免最终出现使用线性域而没有描述符被分配的情况，确保使用简单域的驱动程序在任何 +irq_find_mapping()之前调用irq_create_mapping()是非常重要的，因为后者实际上 +将用于静态IRQ分配情况。 + +irq_domain_add_simple()和irq_domain_create_simple()以及 +irq_domain_add_legacy()和irq_domain_create_legacy()在功能上是等价的，只 +是第一个参数不同--前者接受Open Firmware特定的 'struct device_node' ，而后者 +接受一个更通用的抽象 'struct fwnode_handle' 。 + +IRQ域层级结构 +------------- + +在某些架构上，可能有多个中断控制器参与将一个中断从设备传送到目标CPU。 +让我们来看看x86平台上典型的中断传递路径吧 +:: + + Device --> IOAPIC -> Interrupt remapping Controller -> Local APIC -> CPU + +涉及到的中断控制器有三个: + +1) IOAPIC 控制器 +2) 中断重映射控制器 +3) Local APIC 控制器 + +为了支持这样的硬件拓扑结构，使软件架构与硬件架构相匹配，为每个中断控制器建立一 +个irq_domain数据结构，并将这些irq_domain组织成层次结构。 + +在建立irq_domain层次结构时，靠近设备的irq_domain为子域，靠近CPU的 +irq_domain为父域。所以在上面的例子中，将建立如下的层次结构。 +:: + + CPU Vector irq_domain (root irq_domain to manage CPU vectors) + ^ + | + Interrupt Remapping irq_domain (manage irq_remapping entries) + ^ + | + IOAPIC irq_domain (manage IOAPIC delivery entries/pins) + +使用irq_domain层次结构的主要接口有四个: + +1) irq_domain_alloc_irqs(): 分配IRQ描述符和与中断控制器相关的资源来传递这些中断。 +2) irq_domain_free_irqs(): 释放IRQ描述符和与这些中断相关的中断控制器资源。 +3) irq_domain_activate_irq(): 激活中断控制器硬件以传递中断。 +4) irq_domain_deactivate_irq(): 停用中断控制器硬件，停止传递中断。 + +为了支持irq_domain层次结构，需要做如下修改: + +1) 一个新的字段 'parent' 被添加到irq_domain结构中；它用于维护irq_domain的层次信息。 +2) 一个新的字段 'parent_data' 被添加到irq_data结构中；它用于建立层次结构irq_data以 + 匹配irq_domain层次结构。irq_data用于存储irq_domain指针和硬件irq号。 +3) 新的回调被添加到irq_domain_ops结构中，以支持层次结构的irq_domain操作。 + +在支持分层irq_domain和分层irq_data准备就绪后，为每个中断控制器建立一个irq_domain结 +构，并为每个与IRQ相关联的irq_domain分配一个irq_data结构。现在我们可以再进一步支持堆 +栈式(层次结构)的irq_chip。也就是说，一个irq_chip与层次结构中的每个irq_data相关联。 +一个子irq_chip可以自己或通过与它的父irq_chip合作来实现一个所需的操作。 + +通过堆栈式的irq_chip，中断控制器驱动只需要处理自己管理的硬件，在需要的时候可以向其父 +irq_chip请求服务。所以我们可以实现更简洁的软件架构。 + +为了让中断控制器驱动程序支持irq_domain层次结构，它需要做到以下几点: + +1) 实现 irq_domain_ops.alloc 和 irq_domain_ops.free +2) 可选择地实现 irq_domain_ops.activate 和 irq_domain_ops.deactivate. +3) 可选择地实现一个irq_chip来管理中断控制器硬件。 +4) 不需要实现irq_domain_ops.map和irq_domain_ops.unmap，它们在层次结构 + irq_domain中是不用的。 + +irq_domain层次结构绝不是x86特有的，大量用于支持其他架构，如ARM、ARM64等。 + +调试功能 +======== + +打开CONFIG_GENERIC_IRQ_DEBUGFS，可让IRQ子系统的大部分内部结构都在debugfs中暴露出来。 diff --git

+------------------------------------------------------- + +大多数cpufreq驱动甚至大多数cpu频率升降算法只允许将CPU频率设置为预定义的固定值。对于这些，你 +可以使用->target()，->target_index()或->fast_switch()回调。 + +有些cpufreq功能的处理器可以自己在某些限制之间切换频率。这些应使用->setpolicy()回调。 + + +1.5. target/target_index +------------------------ + +target_index调用有两个参数：``struct cpufreq_policy * policy``和``unsigned int`` +索引(于列出的频率表)。 + +当调用这里时，CPUfreq驱动必须设置新的频率。实际频率必须由freq_table[index].frequency决定。 + +它应该总是在错误的情况下恢复到之前的频率(即policy->restore_freq)，即使我们之前切换到中间频率。 + +已弃用 +---------- +目标调用有三个参数。``struct cpufreq_policy * policy``, unsigned int target_frequency, +unsigned int relation. + +CPUfreq驱动在调用这里时必须设置新的频率。实际的频率必须使用以下规则来确定。 + +- 紧跟 "目标频率"。 +- policy->min <= new_freq <= policy->max (这必须是有效的!!!) +- 如果 relation==CPUFREQ_REL_L，尝试选择一个高于或等于 target_freq 的 new_freq。("L代表 + 最低，但不能低于") +- 如果 relation==CPUFREQ_REL_H，尝试选择一个低于或等于 target_freq 的 new_freq。("H代表 + 最高，但不能高于") + +这里，频率表助手可能会帮助你--详见第2节。 + +1.6. fast_switch +---------------- + +这个函数用于从调度器的上下文进行频率切换。并非所有的驱动都要实现它，因为不允许在这个回调中睡眠。这 +个回调必须经过高度优化，以尽可能快地进行切换。 + +这个函数有两个参数： ``struct cpufreq_policy *policy`` 和 ``unsigned int target_frequency``。 + + +1.7 setpolicy +------------- + +setpolicy调用只需要一个``struct cpufreq_policy * policy``作为参数。需要将处理器内或芯片组内动态频 +率切换的下限设置为policy->min，上限设置为policy->max，如果支持的话，当policy->policy为 +CPUFREQ_POLICY_PERFORMANCE时选择面向性能的设置，当CPUFREQ_POLICY_POWERSAVE时选择面向省电的设置。 +也可以查看drivers/cpufreq/longrun.c中的参考实现。 + +1.8 get_intermediate 和 target_intermediate +-------------------------------------------- + +仅适用于 target_index() 和 CPUFREQ_ASYNC_NOTIFICATION 未设置的驱动。 + +get_intermediate应该返回一个平台想要切换到的稳定的中间频率，target_intermediate()应该将CPU设置为 +该频率，然后再跳转到'index'对应的频率。核心会负责发送通知，驱动不必在target_intermediate()或 +target_index()中处理。 + +在驱动程序不想因为某个目标频率切换到中间频率的情况下，它们可以从get_intermediate()中返回'0'。在这种情况 +下，核心将直接调用->target_index()。 + +注意：->target_index()应该在失败的情况下恢复到policy->restore_freq，因为core会为此发送通知。 + + +2. 频率表助手 +============= + +由于大多数cpufreq处理器只允许被设置为几个特定的频率，因此，一个带有一些函数的 “频率表”可能会辅助处理器驱动 +程序的一些工作。这样的 "频率表" 由一个cpufreq_frequency_table条目构成的数组组成，"driver_data" 中包 +含了驱动程序的具体数值，"frequency" 中包含了相应的频率，并设置了标志。在表的最后，需要添加一个 +cpufreq_frequency_table条目，频率设置为CPUFREQ_TABLE_END。而如果想跳过表中的一个条目，则将频率设置为 +CPUFREQ_ENTRY_INVALID。这些条目不需要按照任何特定的顺序排序，但如果它们是cpufreq 核心会对它们进行快速的DVFS， +因为搜索最佳匹配会更快。 + +如果策略在其policy->freq_table字段中包含一个有效的指针，cpufreq表就会被核心自动验证。 + +cpufreq_frequency_table_verify()保证至少有一个有效的频率在policy->min和policy->max范围内，并且所有其他 +标准都被满足。这对->verify调用很有帮助。 + +cpufreq_frequency_table_target()是对应于->target阶段的频率表助手。只要把数值传递给这个函数，这个函数就会返 +回包含CPU要设置的频率的频率表条目。 + +以下宏可以作为cpufreq_frequency_table的迭代器。 + +cpufreq_for_each_entry(pos, table) - 遍历频率表的所有条目。 + +cpufreq_for_each_valid_entry(pos, table) - 该函数遍历所有条目，不包括CPUFREQ_ENTRY_INVALID频率。 +使用参数 "pos"-一个``cpufreq_frequency_table * `` 作为循环变量，使用参数 "table"-作为你想迭代 +的``cpufreq_frequency_table * `` 。 + +例如:: + + struct cpufreq_frequency_table *pos, *driver_freq_table; + + cpufreq_for_each_entry(pos, driver_freq_table) { + /* Do something with pos */ + pos->frequency = ... + } + +如果你需要在driver_freq_table中处理pos的位置，不要减去指针，因为它的代价相当高。相反，使用宏 +cpufreq_for_each_entry_idx() 和 cpufreq_for_each_valid_entry_idx() 。 diff --git a/Documentation/translations/zh_CN/cpu-freq/cpufreq-stats.rst b/Documentation/translations/zh_CN/cpu-freq/cpufreq-stats.rst new file mode 100644 index 0000000000000000000000000000000000000000..c90d1d8353ed23af62424b413bf289b3c561b9ef --- /dev/null +++ b/Documentation/translations/zh_CN/cpu-freq/cpufreq-stats.rst @@ -0,0 +1,130 @@ +..

+特别是Sphinx `reStructuredText 基础`_ 这是开始学习使用reStructuredText的 +好地方。还有一些 `Sphinx 特殊标记结构`_ 。 + +.. _reStructuredText 基础: http://www.sphinx-doc.org/en/stable/rest.html +.. _Sphinx 特殊标记结构: http://www.sphinx-doc.org/en/stable/markup/index.html + +内核文档的具体指南 +------------------ + +这是一些内核文档的具体指南： + +* 请不要过于痴迷转换格式到reStructuredText。保持简单。在大多数情况下，文档 + 应该是纯文本，格式应足够一致，以便可以转换为其他格式。 + +* 将现有文档转换为reStructuredText时，请尽量减少格式更改。 + +* 在转换文档时，还要更新内容，而不仅仅是格式。 + +* 请遵循标题修饰符的顺序： + + 1. ``=`` 文档标题，要有上线:: + + ======== + 文档标题 + ======== + + 2. ``=`` 章:: + + 章标题 + ====== + + 3. ``-`` 节:: + + 节标题 + ------ + + 4. ``~`` 小节:: + + 小节标题 + ~~~~~~~~ + + 尽管RST没有规定具体的顺序（“没有强加一个固定数量和顺序的节标题装饰风格，最终 + 按照的顺序将是实际遇到的顺序。”），但是拥有一个通用级别的文档更容易遵循。 + +* 对于插入固定宽度的文本块（用于代码样例、用例等）： ``::`` 用于语法高亮意义不 + 大的内容，尤其是短代码段； ``.. code-block:: <language>`` 用于需要语法高亮的 + 较长代码块。对于嵌入到文本中的简短代码片段，请使用 \`\` 。 + + +C域 +--- + +**Sphinx C域（Domain）** （name c）适用于C API文档。例如，函数原型： + +.. code-block:: rst + + .. c:function:: int ioctl( int fd, int request ) + +内核文档的C域有一些附加特性。例如，您可以使用诸如 ``open`` 或 ``ioctl`` 这样的 +通用名称重命名函数的引用名称： + +.. code-block:: rst + + .. c:function:: int ioctl( int fd, int request ) + :name: VIDIOC_LOG_STATUS + +函数名称（例如ioctl）仍保留在输出中，但引用名称从 ``ioctl`` 变为 +``VIDIOC_LOG_STATUS`` 。此函数的索引项也变为 ``VIDIOC_LOG_STATUS`` 。 + +请注意，不需要使用 ``c:func:`` 生成函数文档的交叉引用。由于一些Sphinx扩展的 +神奇力量，如果给定函数名的索引项存在，文档构建系统会自动将对 ``function()`` +的引用转换为交叉引用。如果在内核文档中看到 ``c:func:`` 的用法，请删除它。 + + +列表 +---- + +我们建议使用 *列式表* 格式。 *列式表* 格式是二级列表。与ASCII艺术相比，它们对 +文本文件的读者来说可能没有那么舒适。但其优点是易于创建或修改，而且修改的差异 +（diff）更有意义，因为差异仅限于修改的内容。 + +*平铺表* 也是一个二级列表，类似于 *列式表* ，但具有一些额外特性： + +* 列范围：使用 ``cspan`` 修饰，可以通过其他列扩展单元格 + +* 行范围：使用 ``rspan`` 修饰，可以通过其他行扩展单元格 + +* 自动将表格行最右边的单元格扩展到该行右侧空缺的单元格上。若使用 + ``:fill-cells:`` 选项，此行为可以从 *自动合并* 更改为 *自动插入* ，自动 + 插入（空）单元格，而不是扩展合并到最后一个单元格。 + +选项： + +* ``:header-rows:`` [int] 标题行计数 +* ``:stub-columns:`` [int] 标题列计数 +* ``:widths:`` [[int] [int] ... ] 列宽 +* ``:fill-cells:`` 插入缺少的单元格，而不是自动合并缺少的单元格 + +修饰： + +* ``:cspan:`` [int] 扩展列 +* ``:rspan:`` [int] 扩展行 + +下面的例子演示了如何使用这些标记。分级列表的第一级是 *表格行* 。 *表格行* 中 +只允许一个标记，即该 *表格行* 中的单元格列表。 *comments* （ ``..`` ）和 +*targets* 例外（例如引用 ``:ref:`最后一行 <last row_zh>``` /

，上级目录中的文件。 + +如果要使用相对路径，则需要使用Sphinx的 ``doc`` 修饰。例如，从同一目录引用此页 +的操作如下:: + + 参见 :doc:`sphinx文档的自定义链接文本 <sphinx>`. + +对于大多数用例，前者是首选，因为它更干净，更适合阅读源文件的人。如果您遇到一 +个没有任何特殊作用的 ``:doc:`` 用法，请将其转换为文档路径。 + +有关交叉引用kernel-doc函数或类型的信息，请参阅 +Documentation/doc-guide/kernel-doc.rst 。 + +.. _sphinx_kfigure_zh: + +图形图片 +======== + +如果要添加图片，应该使用 ``kernel-figure`` 和 ``kernel-image`` 指令。例如，

XiangCheng <bobwxc@email.cn> + +============== +内核骇客指北 +============== + +:作者: Rusty Russell + +引言 +===== + +欢迎咱优雅的读者们来阅读Rusty的非常不靠谱的Linux内核骇客（Hacking）指南。本文 +描述了内核代码的常见例程和一般要求：其目标是引导有经验的C程序员入门Linux内核 +开发。我回避了实现细节：这是代码要做的，也忽略了很多有用的例程。 + +在你读这篇文章之前，请理解我从来没有想过要写这篇文章，因为我的资历太低了； +但我一直想读这样的文章，自己写是唯一的方法。我希望它能成长为一个最佳实践、 +通用起点和其他信息的汇编。 + +玩家 +======= + +在任何时候，系统中的每个CPU都可以： + +- 与任何进程无关，服务于硬件中断； + +- 与任何进程无关，服务于软件中断（softirq）或子任务（tasklet）； + +- 运行于内核空间中，与进程（用户上下文）相关联； + +- 在用户空间中运行进程。 + +它们之间有优先级顺序。最下面的两个可以互相抢占，但上面为严格的层次结构： +每个层级只能被上方的抢占。例如，当一个软中断在CPU上运行时，没有其他软中断 +会抢占它，但是硬件中断可以抢占它。不过，系统中的任何其他CPU都是独立执行的。 + +我们将会看到许多方法，用户上下文可以阻止中断，从而成为真正的不可抢占。 + +用户上下文 +------------ + +用户上下文是指当您从系统调用或其他陷阱进入时：就像用户空间一样，您可以被更 +重要的任务和中断抢占。您可以通过调用 :c:func:`schedule()` 进行睡眠。 + +.. note:: + + 在模块加载和卸载以及块设备层上的操作时，你始终处于用户上下文中。 + +在用户上下文中，当前 ``current`` 指针（指示我们当前正在执行的任务）是有效的， +且 :c:func:`in_interrupt()` （ ``include/linux/preempt.h`` ）值为非（false）。 + +.. warning:: + + 请注意，如果您禁用了抢占或软中断（见下文），:c:func:`in_interrupt()` 会 + 返回假阳性。 + +硬件中断（Hard IRQs） +---------------------- + +像定时器、网卡和键盘等都是可能在任意时刻产生中断的真实硬件。内核运行中断 +处理程序，为硬件提供服务。内核确保处理程序永远不会重入：如果相同的中断到达， +它将被排队（或丢弃）。因为它会关闭中断，所以处理程序必须很快：通常它只是 +确认中断，标记一个“软件中断”以执行并退出。 + +您可以通过 :c:func:`in_irq()` 返回真来判断您处于硬件中断状态。 + +.. warning:: + + 请注意，如果中断被禁用，这将返回假阳性（见下文）。 + +软件中断上下文：软中断（Softirqs）与子任务（Tasklets） +------------------------------------------------------- + +当系统调用即将返回用户空间或硬件中断处理程序退出时，任何标记为挂起（通常通 +过硬件中断）的“软件中断”将运行（ ``kernel/softirq.c`` ）。 + +此处完成了许多真正的中断处理工作。在向SMP过渡的早期，只有“bottom halves下半 +部”（BHs）机制，无法利用多个CPU的优势。在从那些一团糟的就电脑切换过来后不久， +我们放弃了这个限制，转而使用“软中断”。 + +``include/linux/interrupt.h`` 列出了不同的软中断。定时器软中断是一个非常重要 +的软中断（ ``include/linux/timer.h`` ）：您可以注册它以在给定时间后为您调用 +函数。 + +软中断通常是一个很难处理的问题，因为同一个软中断将同时在多个CPU上运行。因此， +子任务（ ``include/linux/interrupt.h`` ）更常用：它们是动态可注册的（意味着 +您可以拥有任意数量），并且它们还保证任何子任务都只能在一个CPU上运行，不同的 +子任务也可以同时运行。 + +.. warning:: + + “tasklet”这个名字是误导性的：它们与“任务”无关，可能更多与当时 + 阿列克谢·库兹涅佐夫享用的糟糕伏特加有关。 + +你可以使用 :c:func:`in_softirq()` 宏（ ``include/linux/preempt.h`` ）来确认 +是否处于软中断（或子任务）中。 + +.. warning:: + + 注意，如果持有 :ref:`bottom half lock <local_bh_disable_zh>` 锁，这将返回 + 假阳性。 + +一些基本规则 +================ + +缺少内存保护 + 如果你损坏了内存，无论是在用户上下文还是中断上下文中，整个机器都会崩溃。 + 你确定你不能在用户空间里做你想做的事吗？ + +缺少浮点或MMX + FPU上下文不会被保存；即使在用户上下文中，FPU状态也可能与当前进程不一致： + 您会弄乱某些用户进程的FPU状态。如果真的要这样做，就必须显式地保存/恢复 + 完整的FPU状态（并避免上下文切换）。这通常不是个好主意；请优先用定点算法。 + +严格的堆栈限制 + 对于大多数32位体系结构，根据配置选项的不同内核堆栈大约为3K到6K；对于大 + 多数64位机器，内核堆栈大约为14K，并且经常与中断共享，因此你无法使用全部。 + 应避免深度递归和栈上的巨型本地数组（用动态分配它们来代替）。 + +Linux内核是可移植的 + 就这样吧。您的代码应该是纯64位的，并且不依赖于字节序（endian）。您还应该 + 尽量减少CPU特定的东西，例如内联汇编（inline assembly）应该被干净地封装和 + 最小化以便于移植。一般来说，它应该局限于内核树中有体系结构依赖的部分。 + +输入输出控制（ioctls）：避免编写新的系统调用 +============================================== + +系统调用（system call）通常看起来像这样:: + + asmlinkage long sys_mycall(int arg) + { + return 0; + } + + +首先，在大多数情况下，您无需创建新的系统调用。创建一个字符设备并为其实现适当 +的输入输出控制（ioctls）。这比系统调用灵活得多，不必写进每个体系结构的 +``include/asm/unistd.h`` 和 ``arch/kernel/entry.S`` 文件里，而且更容易被Linus +接受。 + +如果您的程序所做的只是读取或写入一些参数，请考虑实现 :c:func:`sysfs()` 接口。 + +在输入输出控制中，您处于进程的用户上下文。出现错误时，返回一个负的错误参数 +（errno，请参阅 ``include/uapi/asm-generic/errno-base.h`` 、 +``include/uapi/asm-generic/errno.h`` 和 ``include/linux/errno.h`` ），否则返 +回0。 + +在睡眠之后，您应该检查是否出现了信号：Unix/Linux处理信号的方法是暂时退出系统 +调用，并返回 ``-ERESTARTSYS`` 错误。系统调用入口代码将切换回用户上下文，处理 +信号处理程序，然后系统调用将重新启动（除非用户禁用了该功能）。因此，您应该准 +备好处理重新启动，例如若您处理某些数据结构到一半。 + +:: + + if (signal_pending(current)) + return -ERESTARTSYS; + + +如果你要做更长时间的计算：优先考虑用户空间。如果你真的想在内核中做这件事，你 +应该定期检查你是否需要让出CPU（请记得每个CPU都有协作多任务）。 +习惯用法:: + + cond_resched(); /* Will sleep */ + + +接口设计的小注释：UNIX系统调用的格言是“提供机制而不是策略 +Provide mechanism not policy”。 + +死锁的“配方” +==================== + +您不能调用任何可能睡眠的程序，除非： + +- 您处于用户上下文中。 + +- 你未拥有任何自旋锁。 + +- 您已经启用中断（实际上，Andi Kleen说调度代码将为您启用它们，但这可能不是 + 您想要的）。 + +注意，有些函数可能隐式地睡眠：常见的是用户空间访问函数（\*_user）和没有 +``GFP_ATOMIC`` 的内存分配函数。 + +您应该始终打开 ``CONFIG_DEBUG_ATOMIC_SLEEP`` 项来编译内核，如果您违反这些 +规则，它将警告您。如果你 **真的** 违反了规则，你最终会锁住你的电脑。 + +真的会这样。 + + +常用函数/程序 +=============== + +:c:func:`printk()` +------------------ + +定义于 ``include/linux/printk.h`` + +:c:func:`printk()` 将内核消息提供给控制台、dmesg和syslog守护进程。它对于调 +试和报告错误很有用，并且可以在中断上下文中使用，但是使用时要小心：如果机器 +的控制台中充斥着printk消息则会无法使用。它使用与ANSI C printf基本兼容的格式 +字符串，并通过C字符串串联为其提供第一个“优先”参数:: + + printk(KERN_INFO "i = %u\n", i); + + +参见 ``include/linux/kern_levels.h`` ；了解其他 ``KERN_`` 值；syslog将这些值 +解释为级别。特殊用法：打印IP地址使用:: + + __be32 ipaddress; + printk(KERN_INFO "my ip: %pI4\n", &ipaddress); + + +:c:func:`printk()` 内部使用的1K缓冲区，不捕获溢出。请确保足够使用。 + +.. note:: + + 当您开始在用户程序中将printf打成printk时，就知道自己是真正的内核程序员了 + :) + +.. note:: + + 另一个注释：最初的unix第六版源代码在其printf函数的顶部有一个注释：“printf + 不应该用于叽叽喳喳”。你也应该遵循此建议。 + +:c:func:`copy_to_user()` / :c:func:`copy_from_user()` / :c:func:`get_user()` / :c:func:`put_user()` +--------------------------------------------------------------------------------------------------- + +定义于 ``include/linux/uaccess.h`` / ``asm/uaccess.h`` + +**[睡眠]** + +:c:func:`put_user()` 和 :c:func:`get_user()` 用于从用户空间中获取和向用户空 +间中传出单个值（如int、char或long）。指向用户空间的指针永远不应该直接取消 +引用：应该使用这些程序复制数据。两者都返回 ``-EFAULT`` 或 0。 + +:c:func:`copy_to_user()` 和 :c:func:`copy_from_user()` 更通用：它们从/向用户 +空间复制任意数量的数据。 + +.. warning:: + + 与 :c:func:`put_user()` 和 :c:func:`get_user()` 不同，它们返回未复制的 + 数据量（即0仍然意味着成功）。 + +【是的，这个愚蠢的接口真心让我尴尬。火爆的口水仗大概每年都会发生。 +—— Rusty Russell】 + +这些函数可以隐式睡眠。它不应该在用户上下文之外调用（没有意义）、调用时禁用中断 +或获得自旋锁。 + +:c:func:`kmalloc()`/:c:func:`kfree()` +------------------------------------- + +定义于 ``include/linux/slab.h`` + +**[可能睡眠：见下]** + +这些函数用于动态请求指针对齐的内存块，类似用户空间中的malloc和free，但 +:c:func:`kmalloc()` 需要额外的标志词。重要的值： + +``GFP_KERNEL`` + 可以睡眠和交换以释放内存。只允许在用户上下文中使用，但这是分配内存最可靠 + 的方法。 + +``GFP_ATOMIC`` + 不会睡眠。较 ``GFP_KERNEL`` 更不可靠，但可以从中断上下文调用。你 **应该** + 有一个很好的内存不足错误处理策略。 + +``GFP_DMA`` + 分配低于16MB的ISA DMA。如果你不知道那是什么，那你就不需要了。非常不可靠。 + +如果您看到一个从无效上下文警告消息调用的睡眠的函数，那么您可能在没有 +``GFP_ATOMIC`` 的情况下从中断上下文调用了一个睡眠的分配函数。你必须立即修复， +快点！ + +如果你要分配至少 ``PAGE_SIZE`` （ ``asm/page.h`` 或 ``asm/page_types.h`` ） +字节，请考虑使用 :c:func:`__get_free_pages()` （ ``include/linux/gfp.h`` ）。 +它采用顺序参数（0表示页面大小，1表示双页，2表示四页……）和与上述相同的内存 +优先级标志字。 + +如果分配的字节数超过一页，可以使用 :c:func:`vmalloc()` 。它将在内核映射中分 +配虚拟内存。此块在物理内存中不是连续的，但是MMU（内存管理单元）使它看起来像 +是为您准备好的连续空间（因此它只是看起来对cpu连续，对外部设备驱动程序则不然）。 +如果您真的需要为一些奇怪的设备提供大量物理上连续的内存，那么您就会遇到问题： +Linux对此支持很差，因为正在运行的内核中的内存碎片化会使它变得很困难。最好的 +方法是在引导过程的早期通过 :c:func:`alloc_bootmem()` 函数分配。 + +在创建自己的常用对象缓存之前，请考虑使用 ``include/linux/slab.h`` 中的slab +缓存。 + +:c:macro:`current` +------------------ + +定义于 ``include/asm/current.h`` + +此全局变量（其实是宏）包含指向当前任务结构（task structure）的指针，因此仅在 +用户上下文中有效。例如，当进程进行系统调用时，这将指向调用进程的任务结构。 +在中断上下文中不为空（**not NULL**）。 + +:c:func:`mdelay()`/:c:func:`udelay()` +------------------------------------- + +定义于 ``include/asm/delay.h`` / ``include/linux/delay.h`` + +:c:func:`udelay()` 和 :c:func:`ndelay()` 函数可被用于小暂停。不要对它们使用 +大的值，因为这样会导致溢出——帮助函数 :c:func:`mdelay()` 在这里很有用，或者 +考虑 :c:func:`msleep()`。 + +:c:func:`cpu_to_be32()`/:c:func:`be32_to_cpu()`/:c:func:`cpu_to_le32()`/:c:func:`le32_to_cpu()` +----------------------------------------------------------------------------------------------- + +定义于 ``include/asm/byteorder.h`` + +:c:func:`cpu_to_be32()` 系列函数（其中“32”可以替换为64或16，“be”可以替换为 +“le”）是在内核中进行字节序转换的常用方法：它们返回转换后的值。所有的变体也 +提供反向转换函数： +:c:func:`be32_to_cpu()` 等。 + +这些函数有两个主要的变体：指针变体，例如 :c:func:`cpu_to_be32p()` ，它获取 +指向给定类型的指针，并返回转换后的值。另一个变体是“in-situ”系列，例如 +:c:func:`cpu_to_be32s()` ，它转换指针引用的值，并返回void。 + +:c:func:`local_irq_save()`/:c:func:`local_irq_restore()` +-------------------------------------------------------- + +定义于 ``include/linux/irqflags.h`` + + +这些程序禁用本地CPU上的硬中断，并还原它们。它们是可重入的；在其一个 +``unsigned long flags`` 参数中保存以前的状态。如果您知道中断已启用，那么可 +直接使用 :c:func:`local_irq_disable()` 和 :c:func:`local_irq_enable()`。 + +.. _local_bh_disable_zh: + +:c:func:`local_bh_disable()`/:c:func:`local_bh_enable()` +-------------------------------------------------------- + +定义于 ``include/linux/bottom_half.h`` + + +这些程序禁用本地CPU上的软中断，并还原它们。它们是可重入的；如果之前禁用了 +软中断，那么在调用这对函数之后仍然会禁用它们。它们阻止软中断和子任务在当前 +CPU上运行。 + +:c:func:`smp_processor_id()` +---------------------------- + +定义于 ``include/linux/smp.h`` + +:c:func:`get_cpu()` 禁用抢占（这样您就不会突然移动到另一个cpu）并返回当前 +处理器号，介于0和 ``NR_CPUS`` 之间。请注意，CPU编号不一定是连续的。完成后， +使用 :c:func:`put_cpu()` 再次返回。 + +如果您知道您不能被另一个任务抢占（即您处于中断上下文中，或已禁用抢占），您 +可以使用 :c:func:`smp_processor_id()`。 + +``__init``/``__exit``/``__initdata`` +------------------------------------ + +定义于 ``include/linux/init.h`` + +引导之后，内核释放一个特殊的部分；用 ``__init`` 标记的函数和用 ``__initdata`` +标记的数据结构在引导完成后被丢弃：同样地，模块在初始化后丢弃此内存。 +``__exit`` 用于声明只在退出时需要的函数：如果此文件未编译为模块，则该函数将 +被删除。请参阅头文件以使用。请注意，使用 :c:func:`EXPORT_SYMBOL()` 或 +:c:func:`EXPORT_SYMBOL_GPL()` 将标记为 ``__init`` 的函数导出到模块是没有意义 +的——这将出问题。 + + +:c:func:`__initcall()`/:c:func:`module_init()` +---------------------------------------------- + +定义于 ``include/linux/init.h`` / ``include/linux/module.h`` + +内核的许多部分都作为模块（内核的可动态加载部分）良好服务。使用 +:c:func:`module_init()` 和 :c:func:`module_exit()` 宏可以简化代码编写，无需 +``#ifdef`` ，即可以作为模块运行或内置在内核中。 + +:c:func:`module_init()` 宏定义在模块插入时（如果文件编译为模块）或在引导时 +调用哪个函数：如果文件未编译为模块，:c:func:`module_init()` 宏将等效于 +:c:func:`__initcall()` ，它通过链接器的魔力确保在引导时调用该函数。 + +该函数可以返回一个错误值，以导致模块加载失败（不幸的是，如果将模块编译到内核 +中，则此操作无效）。此函数在启用中断的用户上下文中调用，因此可以睡眠。 + +:c:func:`module_exit()` +----------------------- + + +定义于 ``include/linux/module.h`` + +这个宏定义了在模块删除时要调用的函数（如果是编译到内核中的文件，则无用武之地）。 +只有在模块使用计数到零时才会调用它。这个函数也可以睡眠，但不能失败：当它返回 +时，所有的东西都必须清理干净。 + +注意，这个宏是可选的：如果它不存在，您的模块将不可移除（除非 ``rmmod -f`` ）。 + +:c:func:`try_module_get()`/:c:func:`module_put()` +------------------------------------------------- + +定义于 ``include/linux/module.h`` + +这些函数会操作模块使用计数，以防止删除（如果另一个模块使用其导出的符号之一， +则无法删除模块，参见下文）。在调用模块代码之前，您应该在该模块上调用 +:c:func:`try_module_get()` ：若失败，那么该模块将被删除，您应该将其视为不存在。 +若成功，您就可以安全地进入模块，并在完成后调用模块 :c:func:`module_put()` 。 + +大多数可注册结构体都有所有者字段，例如在 +:c:type:`struct file_operations <file_operations>` 结构体中，此字段应设置为 +宏 ``THIS_MODULE`` 。 + +等待队列 ``include/linux/wait.h`` +==================================== + +**[睡眠]** + +等待队列用于等待某程序在条件为真时唤醒另一程序。必须小心使用，以确保没有竞争 +条件。先声明一个 :c:type:`wait_queue_head_t` ，然后对希望等待该条件的进程声明 +一个关于它们自己的 :c:type:`wait_queue_entry_t` ，并将其放入队列中。 + +声明 +----- + +使用 :c:func:`DECLARE_WAIT_QUEUE_HEAD()` 宏声明一个 ``wait_queue_head_t`` ， +或者在初始化代码中使用 :c:func:`init_waitqueue_head()` 程序。 + +排队 +----- + +将自己放在等待队列中相当复杂，因为你必须在检查条件之前将自己放入队列中。有一 +个宏可以来执行此操作： :c:func:`wait_event_interruptible()` +（ ``include/linux/wait.h`` ）第一个参数是等待队列头，第二个参数是计算的表达 +式；当该表达式为true时宏返回0，或者在接收到信号时返回 ``-ERESTARTSYS`` 。 +:c:func:`wait_event()` 版本会忽略信号。 + +唤醒排队任务 +------------- + +调用 :c:func:`wake_up()` （ ``include/linux/wait.h`` ），它将唤醒队列中的所有 +进程。例外情况：如果有一个进程设置了 ``TASK_EXCLUSIVE`` ，队列的其余部分将不 +会被唤醒。这个基本函数的其他变体也可以在同一个头文件中使用。 + +原子操作 +========= + +某些操作在所有平台上都有保证。第一类为操作 :c:type:`atomic_t` +（ ``include/asm/atomic.h`` ）的函数；它包含一个有符号整数（至少32位长）， +您必须使用这些函数来操作或读取 :c:type:`atomic_t` 变量。 +:c:func:`atomic_read()` 和 :c:func:`atomic_set()` 获取并设置计数器，还有 +:c:func:`atomic_add()` ，:c:func:`atomic_sub()` ，:c:func:`atomic_inc()` ， +:c:func:`atomic_dec()` 和 :c:func:`atomic_dec_and_test()` （如果递减为零， +则返回true）。 + +是的。它在原子变量为零时返回true（即!=0）。 + +请注意，这些函数比普通的算术运算速度慢，因此不应过度使用。 + +第二类原子操作是在 ``unsigned long`` （ ``include/linux/bitops.h`` ）上的 +原子位操作。这些操作通常采用指向位模式（bit pattern）的指针，第0位是最低有效 +位。:c:func:`set_bit()`，:c:func:`clear_bit()` 和 :c:func:`change_bit()` 设置、 +清除和更改给定位。:c:func:`test_and_set_bit()` ，:c:func:`test_and_clear_bit()` +和 :c:func:`test_and_change_bit()` 执行相同的操作，但如果之前设置了位，则返回 +true；这些对于原子设置标志特别有用。 + +可以使用大于 ``BITS_PER_LONG`` 位的位索引调用这些操作。但结果在大端序平台上 +不太正常，所以最好不要这样做。 + +符号 +===== + +在内核内部，正常的链接规则仍然适用（即除非用static关键字将符号声明为文件范围， +否则它可以在内核中的任何位置使用）。但是对于模块，会保留一个特殊可导出符号表， +该表将入口点限制为内核内部。模块也可以导出符号。 + +:c:func:`EXPORT_SYMBOL()` +------------------------- + +定义于 ``include/linux/export.h`` + +这是导出符号的经典方法：动态加载的模块将能够正常使用符号。 + +:c:func:`EXPORT_SYMBOL_GPL()` +----------------------------- + +定义于 ``include/linux/export.h`` + + +类似于 :c:func:`EXPORT_SYMBOL()`，只是 :c:func:`EXPORT_SYMBOL_GPL()` 导出的 +符号只能由具有由 :c:func:`MODULE_LICENSE()` 指定GPL兼容许可证的模块看到。这 +意味着此函数被认为是一个内部实现问题，而不是一个真正的接口。一些维护人员和 +开发人员在添加一些新的API或功能时可能却需要导出 EXPORT_SYMBOL_GPL()。 + +:c:func:`EXPORT_SYMBOL_NS()` +---------------------------- + +定义于 ``include/linux/export.h`` + +这是 ``EXPORT_SYMBOL()`` 的变体，允许指定符号命名空间。符号名称空间记录于 +Documentation/core-api/symbol-namespaces.rst 。 + +:c:func:`EXPORT_SYMBOL_NS_GPL()` +-------------------------------- + +定义于 ``include/linux/export.h`` + +这是 ``EXPORT_SYMBOL_GPL()`` 的变体，允许指定符号命名空间。符号名称空间记录于 +Documentation/core-api/symbol-namespaces.rst 。 + +程序与惯例 +=========== + +双向链表 ``include/linux/list.h`` +----------------------------------- + +内核头文件中曾经有三组链表程序，但这一组是赢家。如果你对一个单链表没有特别迫切的 +需求，那么这是一个不错的选择。 + +通常 :c:func:`list_for_each_entry()` 很有用。 + +返回值惯例 +------------ + +对于在用户上下文中调用的代码，违背C语言惯例是很常见的，即返回0表示成功，返回 +负错误值（例如 ``-EFAULT`` ）表示失败。这在一开始可能是不直观的，但在内核中 +相当普遍。 + +使用 :c:func:`ERR_PTR()` （ ``include/linux/err.h`` ）将负错误值编码到指针中， +然后使用 :c:func:`IS_ERR()` 和 :c:func:`PTR_ERR()` 将其再取出：避免为错误值 +使用单独的指针参数。挺讨厌的，但的确是个好方式。 + +破坏编译 +---------- + +Linus和其他开发人员有时会更改开发内核中的函数或结构体名称；这样做不仅是为了 +让每个人都保持警惕，还反映了一个重大的更改（例如，不能再在打开中断的情况下 +调用，或者执行额外的检查，或者不执行以前捕获的检查）。通常这会附带一个linux +内核邮件列表中相当全面的注释；请搜索存档以查看。简单地对文件进行全局替换通常 +会让事情变得 **更糟** 。 + +初始化结构体成员 +------------------ + +初始化结构体的首选方法是使用指定的初始化器，如ISO C99所述。 +例如:: + + static struct block_device_operations opt_fops = { + .open = opt_open, + .release = opt_release, + .ioctl = opt_ioctl, + .check_media_change = opt_media_change, + }; + + +这使得很容易查找（grep），并且可以清楚地看到设置了哪些结构字段。你应该这样做， +因为它看起来很酷。 + +GNU 扩展 +---------- + +Linux内核中明确允许GNU扩展。请注意，由于缺乏通用性，一些更复杂的版本并没有 +得到很好的支持，但以下内容被认为是标准的（有关更多详细信息，请参阅GCC info页 +的“C 扩展”部分——是的，实际上是info页，手册页只是info中内容的简短摘要）。 + +- 内联函数 + +- 语句表达式（Statement expressions）（即（{ 和 }）结构）。 + + +- 声明函数/变量/类型的属性（__attribute__） + +- typeof + +- 零长度数组 + +- 宏变量 + +- 空指针运算 + +- 非常量（Non-Constant）初始化程序 + +- 汇编程序指令（在 arch/ 和 include/asm/ 之内） + +- 字符串函数名（__func__）。 + +- __builtin_constant_p() + +在内核中使用long long时要小心，gcc为其生成的代码非常糟糕：除法和乘法在i386上 +不能工作，因为内核环境中缺少用于它的gcc运行时函数。 + +C++ +--- + +在内核中使用C++通常是个坏主意，因为内核不提供必要的运行时环境，并且不为其 +测试包含文件。不过这仍然是可能的，但不建议。如果你真的想这么做，至少别用 +异常处理（exceptions）。 + +#if +--- + +通常认为，在头文件（或.c文件顶部）中使用宏来抽象函数比在源代码中使用“if”预 +处理器语句更干净。 + +把你的东西放进内核里 +====================== + +为了让你的东西更正式、补丁更整洁，还有一些工作要做： + +- 搞清楚你在谁的地界儿上干活。查看源文件的顶部、 ``MAINTAINERS`` 文件以及 + ``CREDITS`` 文件的最后一部分。你应该和此人协调，确保你没有重新发明轮子， + 或者尝试一些已经被拒绝的东西。 + + 确保你把你的名字和电子邮件地址放在你创建或修改的任何文件的顶部。当人们发 + 现一个缺陷，或者想要做出修改时，这是他们首先会看的地方。 + +- 通常你需要一个配置选项来支持你的内核编程。在适当的目录中编辑 ``Kconfig`` 。 + 配置语言很容易通过剪切和粘贴来使用，在 + Documentation/kbuild/kconfig-language.rst 中有完整的文档。 + + 在您对选项的描述中，请确保同时照顾到了专家用户和对此功能一无所知的用户。 + 在此说明任何不兼容和问题。结尾一定要写上“如有疑问，就选N”（或者是“Y”）； + 这是针对那些看不懂你在说什么的人的。 + +- 编辑 ``Makefile`` ：配置变量在这里导出，因此通常你只需添加一行 + “obj-$(CONFIG_xxx) += xxx.o”。语法记录在 + Documentation/kbuild/makefiles.rst 。 + +- 如果你做了一些有意义的事情，那可以把自己放进 ``CREDITS`` ，通常不止一个 + 文件（无论如何你的名字都应该在源文件的顶部）。维护人员意味着您希望在对 + 子系统进行更改时得到询问，并了解缺陷；这意味着对某部分代码做出更多承诺。 + +- 最后，别忘记去阅读 Documentation/process/submitting-patches.rst ， + 也许还有 Documentation/process/submitting-drivers.rst 。 + +Kernel 仙女棒 +=============== +

Event Initialization +----------------------- + +当用户启动perf命令来监控一些事件时，首先会被用户空间的perf工具解释为多个 +*perf_event_open* 系统调用，然后进一步调用上一步分配的 *event_init* 成员函数 +的主体。 在 *riscv_base_pmu* 的情况下，就是 *riscv_event_init* 。 + +该功能的主要目的是将用户提供的事件翻译成映射图，从而可以直接对HW-related的控 +制寄存器或计数器进行操作。该翻译基于 *riscv_pmu* 中提供的映射和方法。 + +注意，有些功能也可以在这个阶段完成: + +(1) 中断设置，这个在下一节说； +(2) 特限级设置(仅用户空间、仅内核空间、两者都有)； +(3) 析构函数设置。 通常应用 *riscv_destroy_event* 即可； +(4) 对非采样事件的调整，这将被函数应用，如 *perf_adjust_period* ，通常如下:: + + if (!is_sampling_event(event)) { + hwc->sample_period = x86_pmu.max_period; + hwc->last_period = hwc->sample_period; + local64_set(&hwc->period_left, hwc->sample_period); + } + + +在 *riscv_base_pmu* 的情况下，目前只提供了（3）。 + + +3. 中断 +------- + +3.1. 中断初始化 + +这种情况经常出现在 *event_init* 方案的开头。通常情况下，这应该是一个代码段，如:: + + int x86_reserve_hardware(void) + { + int err = 0; + + if (!atomic_inc_not_zero(&pmc_refcount)) { + mutex_lock(&pmc_reserve_mutex); + if (atomic_read(&pmc_refcount) == 0) { + if (!reserve_pmc_hardware()) + err = -EBUSY; + else + reserve_ds_buffers(); + } + if (!err) + atomic_inc(&pmc_refcount); + mutex_unlock(&pmc_reserve_mutex); + } + + return err; + } + +而神奇的是 *reserve_pmc_hardware* ，它通常做原子操作，使实现的IRQ可以从某个全局函 +数指针访问。 而 *release_pmc_hardware* 的作用正好相反，它用在上一节提到的事件分配 +器中。 + + (注：从所有架构的实现来看，*reserve/release* 对总是IRQ设置，所以 *pmc_hardware* + 似乎有些误导。 它并不处理事件和物理计数器之间的绑定，这一点将在下一节介绍。) + +3.2. IRQ结构体 + +基本上，一个IRQ运行以下伪代码:: + + for each hardware counter that triggered this overflow + + get the event of this counter + + // following two steps are defined as *read()*, + // check the section Reading/Writing Counters for details. + count the delta value since previous interrupt + update the event->count (# event occurs) by adding delta, and + event->hw.period_left by subtracting delta + + if the event overflows + sample data + set the counter appropriately for the next overflow + + if the event overflows again + too frequently, throttle this event + fi + fi + + end for + + 然而截至目前，没有一个RISC-V的实现为perf设计了中断，所以具体的实现要在未来完成。 + +4. Reading/Writing 计数 +----------------------- + +它们看似差不多，但perf对待它们的态度却截然不同。 对于读，在 *struct pmu* 中有一个 +*read* 接口，但它的作用不仅仅是读。 根据上下文，*read* 函数不仅要读取计数器的内容 +（event->count），还要更新左周期到下一个中断（event->hw.period_left）。 + + 但 perf 的核心不需要直接写计数器。 写计数器隐藏在以下两点的抽象化之后， + 1） *pmu->start* ，从字面上看就是开始计数，所以必须把计数器设置成一个合适的值，以 + 便下一次中断； + 2）在IRQ里面，应该把计数器设置成同样的合理值。 + +在RISC-V中，读操作不是问题，但写操作就需要费些力气了，因为S模式不允许写计数器。 + + +5. add()/del()/start()/stop() +----------------------------- + +基本思想: add()/del() 向PMU添加/删除事件，start()/stop() 启动/停止PMU中某个事件 +的计数器。 所有这些函数都使用相同的参数: *struct perf_event *event* 和 *int flag* 。 + +把 perf 看作一个状态机，那么你会发现这些函数作为这些状态之间的状态转换过程。 +定义了三种状态（event->hw.state）: + +* PERF_HES_STOPPED: 计数停止 +* PERF_HES_UPTODATE: event->count是最新的 +* PERF_HES_ARCH: 依赖于体系结构的用法，。。。我们现在并不需要它。 + +这些状态转换的正常流程如下: + +* 用户启动一个 perf 事件，导致调用 *event_init* 。 +* 当被上下文切换进来的时候，*add* 会被 perf core 调用，并带有一个标志 PERF_EF_START， + 也就是说事件被添加后应该被启动。 在这个阶段，如果有的话，一般事件会被绑定到一个物 + 理计数器上。当状态变为PERF_HES_STOPPED和PERF_HES_UPTODATE，因为现在已经停止了, + （软件）事件计数不需要更新。 + + - 然后调用 *start* ，并启用计数器。 + 通过PERF_EF_RELOAD标志，它向计数器写入一个适当的值（详细情况请参考上一节）。 + 如果标志不包含PERF_EF_RELOAD，则不会写入任何内容。 + 现在状态被重置为none，因为它既没有停止也没有更新（计数已经开始）。 + +*当被上下文切换出来时被调用。 然后，它检查出PMU中的所有事件，并调用 *stop* 来更新它们 + 的计数。 + + - *stop* 被 *del* 和perf核心调用，标志为PERF_EF_UPDATE，它经常以相同的逻辑和 *read* + 共用同一个子程序。 + 状态又一次变为PERF_HES_STOPPED和PERF_HES_UPTODATE。 + + - 这两对程序的生命周期: *add* 和 *del* 在任务切换时被反复调用；*start* 和 *stop* 在 + perf核心需要快速停止和启动时也会被调用，比如在调整中断周期时。 + +目前的实现已经足够了，将来可以很容易地扩展到功能。 + +A. 相关结构体 +------------- + +* struct pmu: include/linux/perf_event.h +* struct riscv_pmu: arch/riscv/include/asm/perf_event.h + + 两个结构体都被设计为只读。 + + *struct pmu* 定义了一些函数指针接口，它们大多以 *struct perf_event* 作为主参数，根据 + perf的内部状态机处理perf事件（详情请查看kernel/events/core.c）。 + + *struct riscv_pmu* 定义了PMU的具体参数。 命名遵循所有其它架构的惯例。 + +* struct perf_event: include/linux/perf_event.h +* struct hw_perf_event + + 表示 perf 事件的通用结构体，以及硬件相关的细节。 + +* struct riscv_hw_events: arch/riscv/include/asm/perf_event.h + + 保存事件状态的结构有两个固定成员。 + 事件的数量和事件的数组。 + +参考文献 +-------- + +[1] https://github.com/riscv/riscv-linux/pull/124 + +[2] https://groups.google.com/a/groups.riscv.org/forum/#!topic/sw-dev/f19TmCNP6yA diff --git a/Documentation/translations/zh_CN/sound/hd-audio/controls.rst b/Documentation/translations/zh_CN/sound/hd-audio/controls.rst new file mode 100644 index 0000000000000000000000000000000000000000..54c028ab9a4076c8dadc5b5dfa9da70c8ad0ba3c --- /dev/null +++ b/Documentation/translations/zh_CN/sound/hd-audio/controls.rst @@ -0,0 +1,102 @@ +..

There should not be a need for raw attribute macros. diff --git a/drivers/staging/gasket/apex.h b/drivers/staging/gasket/apex.h deleted file mode 100644 index 3bbceffff5e41b628720220df47045173274132f..0000000000000000000000000000000000000000 --- a/drivers/staging/gasket/apex.h +++ /dev/null @@ -1,30 +0,0 @@ -/* SPDX-License-Identifier: GPL-2.0 */ -/* - * Apex kernel-userspace interface definitions. - * - * Copyright (C) 2018 Google, Inc. - */ -#ifndef __APEX_H__ -#define __APEX_H__ - -#include <linux/ioctl.h> - -/* Clock Gating ioctl. */ -struct apex_gate_clock_ioctl { - /* Enter or leave clock gated state. */ - u64 enable; - - /* If set, enter clock gating state, regardless of custom block's - * internal idle state - */ - u64 force_idle; -}; - -/* Base number for all Apex-common IOCTLs */ -#define APEX_IOCTL_BASE 0x7F - -/* Enable/Disable clock gating. */ -#define APEX_IOCTL_GATE_CLOCK \ - _IOW(APEX_IOCTL_BASE, 0, struct apex_gate_clock_ioctl) - -#endif /* __APEX_H__ */ diff --git a/drivers/staging/gasket/apex_driver.c b/drivers/staging/gasket/apex_driver.c deleted file mode 100644 index f12f81c8dd2fb68bfd50ea16d79aa6bc84c2f6f6..0000000000000000000000000000000000000000 --- a/drivers/staging/gasket/apex_driver.c +++ /dev/null @@ -1,726 +0,0 @@ -// SPDX-License-Identifier: GPL-2.0 -/* - * Driver for the Apex chip. - * - * Copyright (C) 2018 Google, Inc. - */ - -#include <linux/compiler.h> -#include <linux/delay.h> -#include <linux/device.h> -#include <linux/fs.h> -#include <linux/init.h> -#include <linux/mm.h> -#include <linux/module.h> -#include <linux/moduleparam.h> -#include <linux/pci.h> -#include <linux/printk.h> -#include <linux/sched.h> -#include <linux/uaccess.h> - -#include "apex.h" - -#include "gasket_core.h" -#include "gasket_interrupt.h" -#include "gasket_page_table.h" -#include "gasket_sysfs.h" - -/* Constants */ -#define APEX_DEVICE_NAME "Apex" -#define APEX_DRIVER_VERSION "1.0" - -/* CSRs are in BAR 2. */ -#define APEX_BAR_INDEX 2 - -#define APEX_PCI_VENDOR_ID 0x1ac1 -#define APEX_PCI_DEVICE_ID 0x089a - -/* Bar Offsets. */ -#define APEX_BAR_OFFSET 0 -#define APEX_CM_OFFSET 0x1000000 - -/* The sizes of each Apex BAR 2. */ -#define APEX_BAR_BYTES 0x100000 -#define APEX_CH_MEM_BYTES (PAGE_SIZE * MAX_NUM_COHERENT_PAGES) - -/* The number of user-mappable memory ranges in BAR2 of a Apex chip. */ -#define NUM_REGIONS 3 - -/* The number of nodes in a Apex chip. */ -#define NUM_NODES 1 - -/* - * The total number of entries in the page table.

Compilation and installation -=============================== - -2.1. Compilation of the drivers included in the kernel ------------------------------------------------------- - - Configure the kernel; to enable the WiMAX drivers select Drivers > - Networking Drivers > WiMAX device support. Enable all of them as - modules (easier). - - If USB or SDIO are not enabled in the kernel configuration, the options - to build the i2400m USB or SDIO drivers will not show. Enable said - subsystems and go back to the WiMAX menu to enable the drivers. - - Compile and install your kernel as usual. - -2.2. Compilation of the drivers distributed as an standalone module -------------------------------------------------------------------- - - To compile:: - - $ cd source/directory - $ make - - Once built you can load and unload using the provided load.sh script; - load.sh will load the modules, load.sh u will unload them. - - To install in the default kernel directories (and enable auto loading - when the device is plugged):: - - $ make install - $ depmod -a - - If your kernel development files are located in a non standard - directory or if you want to build for a kernel that is not the - currently running one, set KDIR to the right location:: - - $ make KDIR=/path/to/kernel/dev/tree - - For more information, please contact linux-wimax@intel.com. - -3. Installing the firmware --------------------------- - - The firmware can be obtained from http://linuxwimax.org or might have - been supplied with your hardware. - - It has to be installed in the target system:: - - $ cp FIRMWAREFILE.sbcf /lib/firmware/i2400m-fw-BUSTYPE-1.3.sbcf - - * NOTE: if your firmware came in an .rpm or .deb file, just install - it as normal, with the rpm (rpm -i FIRMWARE.rpm) or dpkg - (dpkg -i FIRMWARE.deb) commands. No further action is needed. - * BUSTYPE will be usb or sdio, depending on the hardware you have. - Each hardware type comes with its own firmware and will not work - with other types. - -4. Design -========= - - This package contains two major parts: a WiMAX kernel stack and a - driver for the Intel i2400m. - - The WiMAX stack is designed to provide for common WiMAX control - services to current and future WiMAX devices from any vendor; please - see README.wimax for details. - - The i2400m kernel driver is broken up in two main parts: the bus - generic driver and the bus-specific drivers. The bus generic driver - forms the drivercore and contain no knowledge of the actual method we - use to connect to the device. The bus specific drivers are just the - glue to connect the bus-generic driver and the device. Currently only - USB and SDIO are supported. See drivers/net/wimax/i2400m/i2400m.h for - more information. - - The bus generic driver is logically broken up in two parts: OS-glue and - hardware-glue. The OS-glue interfaces with Linux. The hardware-glue - interfaces with the device on using an interface provided by the - bus-specific driver. The reason for this breakup is to be able to - easily reuse the hardware-glue to write drivers for other OSes; note - the hardware glue part is written as a native Linux driver; no - abstraction layers are used, so to port to another OS, the Linux kernel - API calls should be replaced with the target OS's. - -5. Usage -======== - - To load the driver, follow the instructions in the install section; - once the driver is loaded, plug in the device (unless it is permanently - plugged in). The driver will enumerate the device, upload the firmware - and output messages in the kernel log (dmesg, /var/log/messages or - /var/log/kern.log) such as:: - - ... - i2400m_usb 5-4:1.0: firmware interface version 8.0.0 - i2400m_usb 5-4:1.0: WiMAX interface wmx0 (00:1d:e1:01:94:2c) ready - - At this point the device is ready to work. - - Current versions require the Intel WiMAX Network Service in userspace - to make things work. See the network service's README for instructions - on how to scan, connect and disconnect. - -5.1. Module parameters ----------------------- - - Module parameters can be set at kernel or module load time or by - echoing values:: - - $ echo VALUE > /sys/module/MODULENAME/parameters/PARAMETERNAME - - To make changes permanent, for example, for the i2400m module, you can - also create a file named /etc/modprobe.d/i2400m containing:: - - options i2400m idle_mode_disabled=1 - - To find which parameters are supported by a module, run:: - - $ modinfo path/to/module.ko - - During kernel bootup (if the driver is linked in the kernel), specify - the following to the kernel command line:: - - i2400m.PARAMETER=VALUE - -5.1.1. i2400m: idle_mode_disabled -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - The i2400m module supports a parameter to disable idle mode. This - parameter, once set, will take effect only when the device is - reinitialized by the driver (eg: following a reset or a reconnect). - -5.2. Debug operations: debugfs entries --------------------------------------- - - The driver will register debugfs entries that allow the user to tweak - debug settings. There are three main container directories where - entries are placed, which correspond to the three blocks a i2400m WiMAX - driver has: - - * /sys/kernel/debug/wimax:DEVNAME/ for the generic WiMAX stack - controls - * /sys/kernel/debug/wimax:DEVNAME/i2400m for the i2400m generic - driver controls - * /sys/kernel/debug/wimax:DEVNAME/i2400m-usb (or -sdio) for the - bus-specific i2400m-usb or i2400m-sdio controls). - - Of course, if debugfs is mounted in a directory other than - /sys/kernel/debug, those paths will change. - -5.2.1. Increasing debug output -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - The files named *dl_* indicate knobs for controlling the debug output - of different submodules:: - - # find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\* - /sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_tx - /sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_rx - /sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_notif - /sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_fw - /sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_usb - /sys/kernel/debug/wimax:wmx0/i2400m/dl_tx - /sys/kernel/debug/wimax:wmx0/i2400m/dl_rx - /sys/kernel/debug/wimax:wmx0/i2400m/dl_rfkill - /sys/kernel/debug/wimax:wmx0/i2400m/dl_netdev - /sys/kernel/debug/wimax:wmx0/i2400m/dl_fw - /sys/kernel/debug/wimax:wmx0/i2400m/dl_debugfs - /sys/kernel/debug/wimax:wmx0/i2400m/dl_driver - /sys/kernel/debug/wimax:wmx0/i2400m/dl_control - /sys/kernel/debug/wimax:wmx0/wimax_dl_stack - /sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill - /sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset - /sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg - /sys/kernel/debug/wimax:wmx0/wimax_dl_id_table - /sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs - - By reading the file you can obtain the current value of said debug - level; by writing to it, you can set it. - - To increase the debug level of, for example, the i2400m's generic TX - engine, just write:: - - $ echo 3 > /sys/kernel/debug/wimax:wmx0/i2400m/dl_tx - - Increasing numbers yield increasing debug information; for details of - what is printed and the available levels, check the source. The code - uses 0 for disabled and increasing values until 8. - -5.2.2. RX and TX statistics -^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - The i2400m/rx_stats and i2400m/tx_stats provide statistics about the - data reception/delivery from the device:: - - $ cat /sys/kernel/debug/wimax:wmx0/i2400m/rx_stats - 45 1 3 34 3104 48 480 - - The numbers reported are: - - * packets/RX-buffer: total, min, max - * RX-buffers: total RX buffers received, accumulated RX buffer size - in bytes, min size received, max size received - - Thus, to find the average buffer size received, divide accumulated - RX-buffer / total RX-buffers. - - To clear the statistics back to 0, write anything to the rx_stats file:: - - $ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m_rx_stats - - Likewise for TX. - - Note the packets this debug file refers to are not network packet, but - packets in the sense of the device-specific protocol for communication - to the host. See drivers/net/wimax/i2400m/tx.c. - -5.2.3. Tracing messages received from user space -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - To echo messages received from user space into the trace pipe that the - i2400m driver creates, set the debug file i2400m/trace_msg_from_user to - 1:: - - $ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m/trace_msg_from_user - -5.2.4. Performing a device reset -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - By writing a 0, a 1 or a 2 to the file - /sys/kernel/debug/wimax:wmx0/reset, the driver performs a warm (without - disconnecting from the bus), cold (disconnecting from the bus) or bus - (bus specific) reset on the device. - -5.2.5. Asking the device to enter power saving mode -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - By writing any value to the /sys/kernel/debug/wimax:wmx0 file, the - device will attempt to enter power saving mode. - -6. Troubleshooting -================== - -6.1. Driver complains about ``i2400m-fw-usb-1.2.sbcf: request failed`` ----------------------------------------------------------------------- - - If upon connecting the device, the following is output in the kernel - log:: - - i2400m_usb 5-4:1.0: fw i2400m-fw-usb-1.3.sbcf: request failed: -2 - - This means that the driver cannot locate the firmware file named - /lib/firmware/i2400m-fw-usb-1.2.sbcf.

As well, the stack provides API functions that the driver - calls to notify about changes of state in the device. - - The stack exports the API calls needed to control the device to user - space using generic netlink as a marshalling mechanism.

In boot mode we can execute only a handful of commands - * targeted at uploading the firmware and launching it. - * - * The 2400m enters boot mode when it is first connected to the - * system, when it crashes and when you ask it to reboot. There are - * two submodes of the boot mode: signed and non-signed. Signed takes - * firmwares signed with a certain private key, non-signed takes any - * firmware. Normal hardware takes only signed firmware. - * - * On boot mode, in USB, we write to the device using the bulk out - * endpoint and read from it in the notification endpoint. - * - * Upon entrance to boot mode, the device sends (preceded with a few - * zero length packets (ZLPs) on the notification endpoint in USB) a - * reboot barker (4 le32 words with the same value). We ack it by - * sending the same barker to the device. The device acks with a - * reboot ack barker (4 le32 words with value I2400M_ACK_BARKER) and - * then is fully booted. At this point we can upload the firmware. - * - * Note that different iterations of the device and EEPROM - * configurations will send different [re]boot barkers; these are - * collected in i2400m_barker_db along with the firmware - * characteristics they require. - * - * This process is accomplished by the i2400m_bootrom_init() - * function. All the device interaction happens through the - * i2400m_bm_cmd() [boot mode command]. Special return values will - * indicate if the device did reset during the process. - * - * After this, we read the MAC address and then (if needed) - * reinitialize the device. We need to read it ahead of time because - * in the future, we might not upload the firmware until userspace - * 'ifconfig up's the device. - * - * We can then upload the firmware file. The file is composed of a BCF - * header (basic data, keys and signatures) and a list of write - * commands and payloads. Optionally more BCF headers might follow the - * main payload. We first upload the header [i2400m_dnload_init()] and - * then pass the commands and payloads verbatim to the i2400m_bm_cmd() - * function [i2400m_dnload_bcf()]. Then we tell the device to jump to - * the new firmware [i2400m_dnload_finalize()]. - * - * Once firmware is uploaded, we are good to go :) - * - * When we don't know in which mode we are, we first try by sending a - * warm reset request that will take us to boot-mode. If we time out - * waiting for a reboot barker, that means maybe we are already in - * boot mode, so we send a reboot barker. - * - * COMMAND EXECUTION - * - * This code (and process) is single threaded; for executing commands, - * we post a URB to the notification endpoint, post the command, wait - * for data on the notification buffer. We don't need to worry about - * others as we know we are the only ones in there. - * - * BACKEND IMPLEMENTATION - * - * This code is bus-generic; the bus-specific driver provides back end - * implementations to send a boot mode command to the device and to - * read an acknolwedgement from it (or an asynchronous notification) - * from it. - * - * FIRMWARE LOADING - * - * Note that in some cases, we can't just load a firmware file (for - * example, when resuming). For that, we might cache the firmware - * file. Thus, when doing the bootstrap, if there is a cache firmware - * file, it is used; if not, loading from disk is attempted. - * - * ROADMAP - * - * i2400m_barker_db_init Called by i2400m_driver_init() - * i2400m_barker_db_add - * - * i2400m_barker_db_exit Called by i2400m_driver_exit() - * - * i2400m_dev_bootstrap Called by __i2400m_dev_start() - * request_firmware - * i2400m_fw_bootstrap - * i2400m_fw_check - * i2400m_fw_hdr_check - * i2400m_fw_dnload - * release_firmware - * - * i2400m_fw_dnload - * i2400m_bootrom_init - * i2400m_bm_cmd - * i2400m_reset - * i2400m_dnload_init - * i2400m_dnload_init_signed - * i2400m_dnload_init_nonsigned - * i2400m_download_chunk - * i2400m_bm_cmd - * i2400m_dnload_bcf - * i2400m_bm_cmd - * i2400m_dnload_finalize - * i2400m_bm_cmd - * - * i2400m_bm_cmd - * i2400m->bus_bm_cmd_send() - * i2400m->bus_bm_wait_for_ack - * __i2400m_bm_ack_verify - * i2400m_is_boot_barker - * - * i2400m_bm_cmd_prepare Used by bus-drivers to prep - * commands before sending - * - * i2400m_pm_notifier Called on Power Management events - * i2400m_fw_cache - * i2400m_fw_uncache - */ -#include <linux/firmware.h> -#include <linux/sched.h> -#include <linux/slab.h> -#include <linux/usb.h> -#include <linux/export.h> -#include "i2400m.h" - - -#define D_SUBMODULE fw -#include "debug-levels.h" - - -static const __le32 i2400m_ACK_BARKER[4] = { - cpu_to_le32(I2400M_ACK_BARKER), - cpu_to_le32(I2400M_ACK_BARKER), - cpu_to_le32(I2400M_ACK_BARKER), - cpu_to_le32(I2400M_ACK_BARKER) -}; - - -/** - * Prepare a boot-mode command for delivery - * - * @cmd: pointer to bootrom header to prepare - * - * Computes checksum if so needed.

Doesn't need to wait for the - * reset to finish. - * - * If warm or cold reset fail, this function is expected to do a - * bus-specific reset (eg: USB reset) to get the device to a - * working state (even if it implies device disconecction). - * - * Note the warm reset is used by the firmware uploader to - * reinitialize the device. - * - * IMPORTANT: this is called very early in the device setup - * process, so it cannot rely on common infrastructure being laid - * out. - * - * IMPORTANT: don't call reset on RT_BUS with i2400m->init_mutex - * held, as the .pre/.post reset handlers will deadlock. - * - * @bus_bm_retries: [fill] How many times shall a firmware upload / - * device initialization be retried? Different models of the same - * device might need different values, hence it is set by the - * bus-specific driver. Note this value is used in two places, - * i2400m_fw_dnload() and __i2400m_dev_start(); they won't become - * multiplicative (__i2400m_dev_start() calling N times - * i2400m_fw_dnload() and this trying N times to download the - * firmware), as if __i2400m_dev_start() only retries if the - * firmware crashed while initializing the device (not in a - * general case). - * - * @bus_bm_cmd_send: [fill] Function called to send a boot-mode - * command. Flags are defined in 'enum i2400m_bm_cmd_flags'. This - * is synchronous and has to return 0 if ok or < 0 errno code in - * any error condition. - * - * @bus_bm_wait_for_ack: [fill] Function called to wait for a - * boot-mode notification (that can be a response to a previously - * issued command or an asynchronous one). Will read until all the - * indicated size is read or timeout. Reading more or less data - * than asked for is an error condition. Return 0 if ok, < 0 errno - * code on error. - * - * The caller to this function will check if the response is a - * barker that indicates the device going into reset mode. - * - * @bus_fw_names: [fill] a NULL-terminated array with the names of the - * firmware images to try loading. This is made a list so we can - * support backward compatibility of firmware releases (eg: if we - * can't find the default v1.4, we try v1.3). In general, the name - * should be i2400m-fw-X-VERSION.sbcf, where X is the bus name. - * The list is tried in order and the first one that loads is - * used. The fw loader will set i2400m->fw_name to point to the - * active firmware image. - * - * @bus_bm_mac_addr_impaired: [fill] Set to true if the device's MAC - * address provided in boot mode is kind of broken and needs to - * be re-read later on. - * - * @bus_bm_pokes_table: [fill/optional] A table of device addresses - * and values that will be poked at device init time to move the - * device to the correct state for the type of boot/firmware being - * used. This table MUST be terminated with (0x000000, - * 0x00000000) or bad things will happen. - * - * - * @wimax_dev: WiMAX generic device for linkage into the kernel WiMAX - * stack. Due to the way a net_device is allocated, we need to - * force this to be the first field so that we can get from - * netdev_priv() the right pointer. - * - * @updown: the device is up and ready for transmitting control and - * data packets. This implies @ready (communication infrastructure - * with the device is ready) and the device's firmware has been - * loaded and the device initialized. - * - * Write to it only inside a i2400m->init_mutex protected area - * followed with a wmb(); rmb() before accesing (unless locked - * inside i2400m->init_mutex). Read access can be loose like that - * [just using rmb()] because the paths that use this also do - * other error checks later on. - * - * @ready: Communication infrastructure with the device is ready, data - * frames can start to be passed around (this is lighter than - * using the WiMAX state for certain hot paths). - * - * Write to it only inside a i2400m->init_mutex protected area - * followed with a wmb(); rmb() before accesing (unless locked - * inside i2400m->init_mutex). Read access can be loose like that - * [just using rmb()] because the paths that use this also do - * other error checks later on. - * - * @rx_reorder: 1 if RX reordering is enabled; this can only be - * set at probe time. - * - * @state: device's state (as reported by it) - * - * @state_wq: waitqueue that is woken up whenever the state changes - * - * @tx_lock: spinlock to protect TX members - * - * @tx_buf: FIFO buffer for TX; we queue data here - * - * @tx_in: FIFO index for incoming data. Note this doesn't wrap around - * and it is always greater than @tx_out. - * - * @tx_out: FIFO index for outgoing data - * - * @tx_msg: current TX message that is active in the FIFO for - * appending payloads. - * - * @tx_sequence: current sequence number for TX messages from the - * device to the host. - * - * @tx_msg_size: size of the current message being transmitted by the - * bus-specific code. - * - * @tx_pl_num: total number of payloads sent - * - * @tx_pl_max: maximum number of payloads sent in a TX message - * - * @tx_pl_min: minimum number of payloads sent in a TX message - * - * @tx_num: number of TX messages sent - * - * @tx_size_acc: number of bytes in all TX messages sent - * (this is different to net_dev's statistics as it also counts - * control messages). - * - * @tx_size_min: smallest TX message sent. - * - * @tx_size_max: biggest TX message sent. - * - * @rx_lock: spinlock to protect RX members and rx_roq_refcount. - * - * @rx_pl_num: total number of payloads received - * - * @rx_pl_max: maximum number of payloads received in a RX message - * - * @rx_pl_min: minimum number of payloads received in a RX message - * - * @rx_num: number of RX messages received - * - * @rx_size_acc: number of bytes in all RX messages received - * (this is different to net_dev's statistics as it also counts - * control messages). - * - * @rx_size_min: smallest RX message received. - * - * @rx_size_max: buggest RX message received. - * - * @rx_roq: RX ReOrder queues. (fw >= v1.4) When packets are received - * out of order, the device will ask the driver to hold certain - * packets until the ones that are received out of order can be - * delivered. Then the driver can release them to the host. See - * drivers/net/i2400m/rx.c for details. - * - * @rx_roq_refcount: refcount rx_roq. This refcounts any access to - * rx_roq thus preventing rx_roq being destroyed when rx_roq - * is being accessed. rx_roq_refcount is protected by rx_lock. - * - * @rx_reports: reports received from the device that couldn't be - * processed because the driver wasn't still ready; when ready, - * they are pulled from here and chewed. - * - * @rx_reports_ws: Work struct used to kick a scan of the RX reports - * list and to process each. - * - * @src_mac_addr: MAC address used to make ethernet packets be coming - * from. This is generated at i2400m_setup() time and used during - * the life cycle of the instance. See i2400m_fake_eth_header(). - * - * @init_mutex: Mutex used for serializing the device bringup - * sequence; this way if the device reboots in the middle, we - * don't try to do a bringup again while we are tearing down the - * one that failed. - * - * Can't reuse @msg_mutex because from within the bringup sequence - * we need to send messages to the device and thus use @msg_mutex. - * - * @msg_mutex: mutex used to send control commands to the device (we - * only allow one at a time, per host-device interface design). - * - * @msg_completion: used to wait for an ack to a control command sent - * to the device. - * - * @ack_skb: used to store the actual ack to a control command if the - * reception of the command was successful. Otherwise, a ERR_PTR() - * errno code that indicates what failed with the ack reception. - * - * Only valid after @msg_completion is woken up. Only updateable - * if @msg_completion is armed. Only touched by - * i2400m_msg_to_dev(). - * - * Protected by @rx_lock. In theory the command execution flow is - * sequential, but in case the device sends an out-of-phase or - * very delayed response, we need to avoid it trampling current - * execution. - * - * @bm_cmd_buf: boot mode command buffer for composing firmware upload - * commands. - * - * USB can't r/w to stack, vmalloc, etc...as well, we end up - * having to alloc/free a lot to compose commands, so we use these - * for stagging and not having to realloc all the time. - * - * This assumes the code always runs serialized. Only one thread - * can call i2400m_bm_cmd() at the same time. - * - * @bm_ack_buf: boot mode acknoledge buffer for staging reception of - * responses to commands. - * - * See @bm_cmd_buf. - * - * @work_queue: work queue for processing device reports. This - * workqueue cannot be used for processing TX or RX to the device, - * as from it we'll process device reports, which might require - * further communication with the device. - * - * @debugfs_dentry: hookup for debugfs files. - * These have to be in a separate directory, a child of - * (wimax_dev->debugfs_dentry) so they can be removed when the - * module unloads, as we don't keep each dentry. - * - * @fw_name: name of the firmware image that is currently being used. - * - * @fw_version: version of the firmware interface, Major.minor, - * encoded in the high word and low word (major << 16 | minor). - * - * @fw_hdrs: NULL terminated array of pointers to the firmware - * headers. This is only available during firmware load time. - * - * @fw_cached: Used to cache firmware when the system goes to - * suspend/standby/hibernation (as on resume we can't read it). If - * NULL, no firmware was cached, read it. If ~0, you can't read - * any firmware files (the system still didn't come out of suspend - * and failed to cache one), so abort; otherwise, a valid cached - * firmware to be used. Access to this variable is protected by - * the spinlock i2400m->rx_lock. - * - * @barker: barker type that the device uses; this is initialized by - * i2400m_is_boot_barker() the first time it is called. Then it - * won't change during the life cycle of the device and every time - * a boot barker is received, it is just verified for it being the - * same. - * - * @pm_notifier: used to register for PM events - * - * @bus_reset_retries: counter for the number of bus resets attempted for - * this boot. It's not for tracking the number of bus resets during - * the whole driver life cycle (from insmod to rmmod) but for the - * number of dev_start() executed until dev_start() returns a success - * (ie: a good boot means a dev_stop() followed by a successful - * dev_start()). dev_reset_handler() increments this counter whenever - * it is triggering a bus reset. It checks this counter to decide if a - * subsequent bus reset should be retried. dev_reset_handler() retries - * the bus reset until dev_start() succeeds or the counter reaches - * I2400M_BUS_RESET_RETRIES. The counter is cleared to 0 in - * dev_reset_handle() when dev_start() returns a success, - * ie: a successul boot is completed. - * - * @alive: flag to denote if the device *should* be alive. This flag is - * everything like @updown (see doc for @updown) except reflecting - * the device state *we expect* rather than the actual state as denoted - * by @updown. It is set 1 whenever @updown is set 1 in dev_start(). - * Then the device is expected to be alive all the time - * (i2400m->alive remains 1) until the driver is removed. Therefore - * all the device reboot events detected can be still handled properly - * by either dev_reset_handle() or .pre_reset/.post_reset as long as - * the driver presents. It is set 0 along with @updown in dev_stop(). - * - * @error_recovery: flag to denote if we are ready to take an error recovery. - * 0 for ready to take an error recovery; 1 for not ready. It is - * initialized to 1 while probe() since we don't tend to take any error - * recovery during probe(). It is decremented by 1 whenever dev_start() - * succeeds to indicate we are ready to take error recovery from now on. - * It is checked every time we wanna schedule an error recovery. If an - * error recovery is already in place (error_recovery was set 1), we - * should not schedule another one until the last one is done. - */ -struct i2400m { - struct wimax_dev wimax_dev; /* FIRST!

See drivers/net/wimax/i2400m/fw.c for more - * details. - * - * The BCF data structure is for the firmware file header. - * - * - * THE DATA / CONTROL PROTOCOL - * - * This is the normal protocol spoken with the device once the - * firmware is uploaded. It transports data payloads and control - * messages back and forth. - * - * It consists 'messages' that pack one or more payloads each. The - * format is described in detail in drivers/net/wimax/i2400m/rx.c and - * tx.c. - * - * - * THE L3L4 PROTOCOL - * - * The term L3L4 refers to Layer 3 (the device), Layer 4 (the - * driver/host software). - * - * This is the control protocol used by the host to control the i2400m - * device (scan, connect, disconnect...). This is sent to / received - * as control frames. These frames consist of a header and zero or - * more TLVs with information. We call each control frame a "message". - * - * Each message is composed of: - * - * HEADER - * [TLV0 + PAYLOAD0] - * [TLV1 + PAYLOAD1] - * [...] - * [TLVN + PAYLOADN] - * - * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are - * defined by a TLV structure (Type Length Value) which is a 'header' - * (struct i2400m_tlv_hdr) and then the payload. - * - * All integers are represented as Little Endian. - * - * - REQUESTS AND EVENTS - * - * The requests can be clasified as follows: - * - * COMMAND: implies a request from the host to the device requesting - * an action being performed. The device will reply with a - * message (with the same type as the command), status and - * no (TLV) payload. Execution of a command might cause - * events (of different type) to be sent later on as - * device's state changes. - * - * GET/SET: similar to COMMAND, but will not cause other - * EVENTs. The reply, in the case of GET, will contain - * TLVs with the requested information. - * - * EVENT: asynchronous messages sent from the device, maybe as a - * consequence of previous COMMANDs but disassociated from - * them. - * - * Only one request might be pending at the same time (ie: don't - * parallelize nor post another GET request before the previous - * COMMAND has been acknowledged with it's corresponding reply by the - * device). - * - * The different requests and their formats are described below: - * - * I2400M_MT_* Message types - * I2400M_MS_* Message status (for replies, events) - * i2400m_tlv_* TLVs - * - * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the - * operation. - */ - -#ifndef __LINUX__WIMAX__I2400M_H__ -#define __LINUX__WIMAX__I2400M_H__ - -#include <linux/types.h> -#include <linux/if_ether.h> - -/* - * Host Device Interface (HDI) common to all busses - */ - -/* Boot-mode (firmware upload mode) commands */ - -/* Header for the firmware file */ -struct i2400m_bcf_hdr { - __le32 module_type; - __le32 header_len; - __le32 header_version; - __le32 module_id; - __le32 module_vendor; - __le32 date; /* BCD YYYMMDD */ - __le32 size; /* in dwords */ - __le32 key_size; /* in dwords */ - __le32 modulus_size; /* in dwords */ - __le32 exponent_size; /* in dwords */ - __u8 reserved[88]; -} __attribute__ ((packed)); - -/* Boot mode opcodes */ -enum i2400m_brh_opcode { - I2400M_BRH_READ = 1, - I2400M_BRH_WRITE = 2, - I2400M_BRH_JUMP = 3, - I2400M_BRH_SIGNED_JUMP = 8, - I2400M_BRH_HASH_PAYLOAD_ONLY = 9, -}; - -/* Boot mode command masks and stuff */ -enum i2400m_brh { - I2400M_BRH_SIGNATURE = 0xcbbc0000, - I2400M_BRH_SIGNATURE_MASK = 0xffff0000, - I2400M_BRH_SIGNATURE_SHIFT = 16, - I2400M_BRH_OPCODE_MASK = 0x0000000f, - I2400M_BRH_RESPONSE_MASK = 0x000000f0, - I2400M_BRH_RESPONSE_SHIFT = 4, - I2400M_BRH_DIRECT_ACCESS = 0x00000400, - I2400M_BRH_RESPONSE_REQUIRED = 0x00000200, - I2400M_BRH_USE_CHECKSUM = 0x00000100, -}; - - -/** - * i2400m_bootrom_header - Header for a boot-mode command - * - * @cmd: the above command descriptor - * @target_addr: where on the device memory should the action be performed. - * @data_size: for read/write, amount of data to be read/written - * @block_checksum: checksum value (if applicable) - * @payload: the beginning of data attached to this header - */ -struct i2400m_bootrom_header { - __le32 command; /* Compose with enum i2400_brh */ - __le32 target_addr; - __le32 data_size; - __le32 block_checksum; - char payload[0]; -} __attribute__ ((packed)); - - -/* - * Data / control protocol - */ - -/* Packet types for the host-device interface */ -enum i2400m_pt { - I2400M_PT_DATA = 0, - I2400M_PT_CTRL, - I2400M_PT_TRACE, /* For device debug */ - I2400M_PT_RESET_WARM, /* device reset */ - I2400M_PT_RESET_COLD, /* USB[transport] reset, like reconnect */ - I2400M_PT_EDATA, /* Extended RX data */ - I2400M_PT_ILLEGAL -}; - - -/* - * Payload for a data packet - * - * This is prefixed to each and every outgoing DATA type. - */ -struct i2400m_pl_data_hdr { - __le32 reserved; -} __attribute__((packed)); - - -/* - * Payload for an extended data packet - * - * New in fw v1.4 - * - * @reorder: if this payload has to be reorder or not (and how) - * @cs: the type of data in the packet, as defined per (802.16e - * T11.13.19.1).

As well, most traffic is going - * to be download (vs upload). - * - * The format for sending/receiving data to/from the i2400m is - * described in detail in rx.c:PROTOCOL FORMAT. In here we implement - * the transmission of that. This is split between a bus-independent - * part that just prepares everything and a bus-specific part that - * does the actual transmission over the bus to the device (in the - * bus-specific driver). - * - * - * The general format of a device-host transaction is MSG-HDR, PLD1, - * PLD2...PLDN, PL1, PL2,...PLN, PADDING. - * - * Because we need the send payload descriptors and then payloads and - * because it is kind of expensive to do scatterlists in USB (one URB - * per node), it becomes cheaper to append all the data to a FIFO - * (copying to a FIFO potentially in cache is cheaper). - * - * Then the bus-specific code takes the parts of that FIFO that are - * written and passes them to the device. - * - * So the concepts to keep in mind there are: - * - * We use a FIFO to queue the data in a linear buffer. We first append - * a MSG-HDR, space for I2400M_TX_PLD_MAX payload descriptors and then - * go appending payloads until we run out of space or of payload - * descriptors. Then we append padding to make the whole transaction a - * multiple of i2400m->bus_tx_block_size (as defined by the bus layer). - * - * - A TX message: a combination of a message header, payload - * descriptors and payloads. - * - * Open: it is marked as active (i2400m->tx_msg is valid) and we - * can keep adding payloads to it. - * - * Closed: we are not appending more payloads to this TX message - * (exahusted space in the queue, too many payloads or - * whichever). We have appended padding so the whole message - * length is aligned to i2400m->bus_tx_block_size (as set by the - * bus/transport layer). - * - * - Most of the time we keep a TX message open to which we append - * payloads. - * - * - If we are going to append and there is no more space (we are at - * the end of the FIFO), we close the message, mark the rest of the - * FIFO space unusable (skip_tail), create a new message at the - * beginning of the FIFO (if there is space) and append the message - * there. - * - * This is because we need to give linear TX messages to the bus - * engine. So we don't write a message to the remaining FIFO space - * until the tail and continue at the head of it. - * - * - We overload one of the fields in the message header to use it as - * 'size' of the TX message, so we can iterate over them. It also - * contains a flag that indicates if we have to skip it or not. - * When we send the buffer, we update that to its real on-the-wire - * value. - * - * - The MSG-HDR PLD1...PLD2 stuff has to be a size multiple of 16. - * - * It follows that if MSG-HDR says we have N messages, the whole - * header + descriptors is 16 + 4*N; for those to be a multiple of - * 16, it follows that N can be 4, 8, 12, ... (32, 48, 64, 80... - * bytes). - * - * So if we have only 1 payload, we have to submit a header that in - * all truth has space for 4. - * - * The implication is that we reserve space for 12 (64 bytes); but - * if we fill up only (eg) 2, our header becomes 32 bytes only. So - * the TX engine has to shift those 32 bytes of msg header and 2 - * payloads and padding so that right after it the payloads start - * and the TX engine has to know about that. - * - * It is cheaper to move the header up than the whole payloads down. - * - * We do this in i2400m_tx_close(). See 'i2400m_msg_hdr->offset'. - * - * - Each payload has to be size-padded to 16 bytes; before appending - * it, we just do it. - * - * - The whole message has to be padded to i2400m->bus_tx_block_size; - * we do this at close time. Thus, when reserving space for the - * payload, we always make sure there is also free space for this - * padding that sooner or later will happen. - * - * When we append a message, we tell the bus specific code to kick in - * TXs. It will TX (in parallel) until the buffer is exhausted--hence - * the lockin we do. The TX code will only send a TX message at the - * time (which remember, might contain more than one payload). Of - * course, when the bus-specific driver attempts to TX a message that - * is still open, it gets closed first. - * - * Gee, this is messy; well a picture. In the example below we have a - * partially full FIFO, with a closed message ready to be delivered - * (with a moved message header to make sure it is size-aligned to - * 16), TAIL room that was unusable (and thus is marked with a message - * header that says 'skip this') and at the head of the buffer, an - * incomplete message with a couple of payloads. - * - * N ___________________________________________________ - * | | - * | TAIL room | - * | | - * | msg_hdr to skip (size |= 0x80000) | - * |---------------------------------------------------|------- - * | | /|\ - * | | | - * | TX message padding | | - * | | | - * | | | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -| | - * | | | - * | payload 1 | | - * | | N * tx_block_size - * | | | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -| | - * | | | - * | payload 1 | | - * | | | - * | | | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -|- -|- - - - - * | padding 3 /|\ | | /|\ - * | padding 2 | | | | - * | pld 1 32 bytes (2 * 16) | | | - * | pld 0 | | | | - * | moved msg_hdr \|/ | \|/ | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -|- - - | - * | | _PLD_SIZE - * | unused | | - * | | | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -| | - * | msg_hdr (size X) [this message is closed] | \|/ - * |===================================================|========== <=== OUT - * | | - * | | - * | | - * | Free rooom | - * | | - * | | - * | | - * | | - * | | - * | | - * | | - * | | - * | | - * |===================================================|========== <=== IN - * | | - * | | - * | | - * | | - * | payload 1 | - * | | - * | | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -| - * | | - * | payload 0 | - * | | - * | | - * |- - - - - - - - - - - - - - - - - - - - - - - - - -| - * | pld 11 /|\ | - * | ... | | - * | pld 1 64 bytes (2 * 16) | - * | pld 0 | | - * | msg_hdr (size X) \|/ [message is open] | - * 0 --------------------------------------------------- - * - * - * ROADMAP - * - * i2400m_tx_setup() Called by i2400m_setup - * i2400m_tx_release() Called by i2400m_release() - * - * i2400m_tx() Called to send data or control frames - * i2400m_tx_fifo_push() Allocates append-space in the FIFO - * i2400m_tx_new() Opens a new message in the FIFO - * i2400m_tx_fits() Checks if a new payload fits in the message - * i2400m_tx_close() Closes an open message in the FIFO - * i2400m_tx_skip_tail() Marks unusable FIFO tail space - * i2400m->bus_tx_kick() - * - * Now i2400m->bus_tx_kick() is the the bus-specific driver backend - * implementation; that would do: - * - * i2400m->bus_tx_kick() - * i2400m_tx_msg_get() Gets first message ready to go - * ...sends it... - * i2400m_tx_msg_sent() Ack the message is sent; repeat from - * _tx_msg_get() until it returns NULL - * (FIFO empty). - */ -#include <linux/netdevice.h> -#include <linux/slab.h> -#include <linux/export.h> -#include "i2400m.h" - - -#define D_SUBMODULE tx -#include "debug-levels.h" - -enum { - /** - * TX Buffer size - * - * Doc says maximum transaction is 16KiB.

Remember this is meant to grow as new common - * operations are decided upon.

This allows to have multiple applications - * monitoring them. - * - * Each command/signal gets assigned it's own attribute policy. This - * way the validator will verify that all the attributes in there are - * only the ones that should be for each command/signal. Thing of an - * attribute mapping to a type+argumentname for each command/signal. - * - * If we had a single policy for *all* commands/signals, after running - * the validator we'd have to check "does this attribute belong in - * here"? for each one. It can be done manually, but it's just easier - * to have the validator do that job with multiple policies. As well, - * it makes it easier to later expand each command/signal signature - * without affecting others and keeping the namespace more or less - * sane. Not that it is too complicated, but it makes it even easier. - * - * No state information is maintained in the kernel for each user - * space connection (the connection is stateless). - * - * TESTING FOR THE INTERFACE AND VERSIONING - * - * If network interface X is a WiMAX device, there will be a Generic - * Netlink family named "WiMAX X" and the device will present a - * "wimax" directory in it's network sysfs directory - * (/sys/class/net/DEVICE/wimax) [used by HAL]. - * - * The inexistence of any of these means the device does not support - * this WiMAX API. - * - * By querying the generic netlink controller, versioning information - * and the multicast groups available can be found. Applications using - * the interface can either rely on that or use the generic netlink - * controller to figure out which generic netlink commands/signals are - * supported. - * - * NOTE: this versioning is a last resort to avoid hard - * incompatibilities. It is the intention of the design of this - * stack not to introduce backward incompatible changes. - * - * The version code has to fit in one byte (restrictions imposed by - * generic netlink); we use `version / 10` for the major version and - * `version % 10` for the minor. This gives 9 minors for each major - * and 25 majors. - * - * The version change protocol is as follow: - * - * - Major versions: needs to be increased if an existing message/API - * call is changed or removed. Doesn't need to be changed if a new - * message is added. - * - * - Minor version: needs to be increased if new messages/API calls are - * being added or some other consideration that doesn't impact the - * user-kernel interface too much (like some kind of bug fix) and - * that is kind of left up in the air to common sense. - * - * User space code should not try to work if the major version it was - * compiled for differs from what the kernel offers. As well, if the - * minor version of the kernel interface is lower than the one user - * space is expecting (the one it was compiled for), the kernel - * might be missing API calls; user space shall be ready to handle - * said condition. Use the generic netlink controller operations to - * find which ones are supported and which not. - * - * libwimaxll:wimaxll_open() takes care of checking versions. - * - * THE OPERATIONS: - * - * Each operation is defined in its on file (drivers/net/wimax/op-*.c) - * for clarity. The parts needed for an operation are: - * - * - a function pointer in `struct wimax_dev`: optional, as the - * operation might be implemented by the stack and not by the - * driver. - * - * All function pointers are named wimax_dev->op_*(), and drivers - * must implement them except where noted otherwise. - * - * - When exported to user space, a `struct nla_policy` to define the - * attributes of the generic netlink command and a `struct genl_ops` - * to define the operation. - * - * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>) - * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in - * include/linux/wimax.h; this file is intended to be cloned by user - * space to gain access to those declarations. - * - * A few caveats to remember: - * - * - Need to define attribute numbers starting in 1; otherwise it - * fails. - * - * - the `struct genl_family` requires a maximum attribute id; when - * defining the `struct nla_policy` for each message, it has to have - * an array size of WIMAX_GNL_ATTR_MAX+1. - * - * The op_*() function pointers will not be called if the wimax_dev is - * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is: - * - * - op_reset: can be called at any time after wimax_dev_add() has - * been called. - * - * THE PIPE INTERFACE: - * - * This interface is kept intentionally simple. The driver can send - * and receive free-form messages to/from user space through a - * pipe. See drivers/net/wimax/op-msg.c for details. - * - * The kernel-to-user messages are sent with - * wimax_msg(). user-to-kernel messages are delivered via - * wimax_dev->op_msg_from_user(). - * - * RFKILL: - * - * RFKILL support is built into the wimax_dev layer; the driver just - * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in - * the hardware or software RF kill switches. When the stack wants to - * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(), - * which the driver implements. - * - * User space can set the software RF Kill switch by calling - * wimax_rfkill(). - * - * The code for now only supports devices that don't require polling; - * If the device needs to be polled, create a self-rearming delayed - * work struct for polling or look into adding polled support to the - * WiMAX stack. - * - * When initializing the hardware (_probe), after calling - * wimax_dev_add(), query the device for it's RF Kill switches status - * and feed it back to the WiMAX stack using - * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always - * report it as ON. - * - * NOTE: the wimax stack uses an inverted terminology to that of the - * RFKILL subsystem: - * - * - ON: radio is ON, RFKILL is DISABLED or OFF. - * - OFF: radio is OFF, RFKILL is ENABLED or ON. - * - * MISCELLANEOUS OPS: - * - * wimax_reset() can be used to reset the device to power on state; by - * default it issues a warm reset that maintains the same device - * node. If that is not possible, it falls back to a cold reset - * (device reconnect).

Embed a &struct wimax_dev at *the beginning* the network - * device structure so that netdev_priv() points to it. - * - * 2. memset() it to zero - * - * 3. Initialize with wimax_dev_init(). This will leave the WiMAX - * device in the %__WIMAX_ST_NULL state. - * - * 4. Fill all the fields marked with [fill]; once called - * wimax_dev_add(), those fields CANNOT be modified. - * - * 5. Call wimax_dev_add() *after* registering the network - * device. This will leave the WiMAX device in the %WIMAX_ST_DOWN - * state. - * Protect the driver's net_device->open() against succeeding if - * the wimax device state is lower than %WIMAX_ST_DOWN. - * - * 6. Select when the device is going to be turned on/initialized; - * for example, it could be initialized on 'ifconfig up' (when the - * netdev op 'open()' is called on the driver). - * - * When the device is initialized (at `ifconfig up` time, or right - * after calling wimax_dev_add() from _probe(), make sure the - * following steps are taken - * - * a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so - * some API calls that shouldn't work until the device is ready - * can be blocked. - * - * b. Initialize the device. Make sure to turn the SW radio switch - * off and move the device to state %WIMAX_ST_RADIO_OFF when - * done. When just initialized, a device should be left in RADIO - * OFF state until user space devices to turn it on. - * - * c. Query the device for the state of the hardware rfkill switch - * and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw() - * as needed. See below. - * - * wimax_dev_rm() undoes before unregistering the network device. Once - * wimax_dev_add() is called, the driver can get called on the - * wimax_dev->op_* function pointers - * - * CONCURRENCY: - * - * The stack provides a mutex for each device that will disallow API - * calls happening concurrently; thus, op calls into the driver - * through the wimax_dev->op*() function pointers will always be - * serialized and *never* concurrent. - * - * For locking, take wimax_dev->mutex is taken; (most) operations in - * the API have to check for wimax_dev_is_ready() to return 0 before - * continuing (this is done internally). - * - * REFERENCE COUNTING: - * - * The WiMAX device is reference counted by the associated network - * device. The only operation that can be used to reference the device - * is wimax_dev_get_by_genl_info(), and the reference it acquires has - * to be released with dev_put(wimax_dev->net_dev). - * - * RFKILL: - * - * At startup, both HW and SW radio switchess are assumed to be off. - * - * At initialization time [after calling wimax_dev_add()], have the - * driver query the device for the status of the software and hardware - * RF kill switches and call wimax_report_rfkill_hw() and - * wimax_rfkill_report_sw() to indicate their state. If any is - * missing, just call it to indicate it is ON (radio always on). - * - * Whenever the driver detects a change in the state of the RF kill - * switches, it should call wimax_report_rfkill_hw() or - * wimax_report_rfkill_sw() to report it to the stack. - */ -struct wimax_dev { - struct net_device *net_dev; - struct list_head id_table_node; - struct mutex mutex; /* Protects all members and API calls */ - struct mutex mutex_reset; - enum wimax_st state; - - int (*op_msg_from_user)(struct wimax_dev *wimax_dev, - const char *, - const void *, size_t, - const struct genl_info *info); - int (*op_rfkill_sw_toggle)(struct wimax_dev *wimax_dev, - enum wimax_rf_state); - int (*op_reset)(struct wimax_dev *wimax_dev); - - struct rfkill *rfkill; - unsigned int rf_hw; - unsigned int rf_sw; - char name[32]; - - struct dentry *debugfs_dentry; -}; - - - -/* - * WiMAX stack public API for device drivers - * ----------------------------------------- - * - * These functions are not exported to user space. - */ -void wimax_dev_init(struct wimax_dev *); -int wimax_dev_add(struct wimax_dev *, struct net_device *); -void wimax_dev_rm(struct wimax_dev *); - -static inline -struct wimax_dev *net_dev_to_wimax(struct net_device *net_dev) -{ - return netdev_priv(net_dev); -} - -static inline -struct device *wimax_dev_to_dev(struct wimax_dev *wimax_dev) -{ - return wimax_dev->net_dev->dev.parent; -} - -void wimax_state_change(struct wimax_dev *, enum wimax_st); -enum wimax_st wimax_state_get(struct wimax_dev *); - -/* - * Radio Switch state reporting. - * - * enum wimax_rf_state is declared in linux/wimax.h so the exports - * to user space can use it. - */ -void wimax_report_rfkill_hw(struct wimax_dev *, enum wimax_rf_state); -void wimax_report_rfkill_sw(struct wimax_dev *, enum wimax_rf_state); - - -/* - * Free-form messaging to/from user space - * - * Sending a message: - * - * wimax_msg(wimax_dev, pipe_name, buf, buf_size, GFP_KERNEL); - * - * Broken up: - * - * skb = wimax_msg_alloc(wimax_dev, pipe_name, buf_size, GFP_KERNEL); - * ...fill up skb... - * wimax_msg_send(wimax_dev, pipe_name, skb); - * - * Be sure not to modify skb->data in the middle (ie: don't use - * skb_push()/skb_pull()/skb_reserve() on the skb). - * - * "pipe_name" is any string, that can be interpreted as the name of - * the pipe or recipient; the interpretation of it is driver - * specific, so the recipient can multiplex it as wished.
