For the PMIC7-type PMICs, ADC peripheral is present in HW for the following PMICs: PMK8350, PM8350, PM8350b, PMR735a and PMR735b. Of these, only the ADC peripheral on PMK8350 is exposed directly to SW. If SW needs to communicate with ADCs on other PMICs, it specifies the PMIC to PMK8350 through the newly added SID register and communication between PMK8350 ADC and other PMIC ADCs is carried out through PBS(Programmable Boot Sequence) at the firmware level. In addition, add definitions for ADC channels and virtual channel definitions (combination of ADC channel number and PMIC SID number) per PMIC, to be used by ADC clients for PMIC7.

The major change from PMIC5 is that all SW communication to ADC goes through PMK8350, which communicates with other PMICs through PBS when the ADC on PMK8350 works in master mode. The SID register is used to identify the PMICs with which the PBS needs to communicate. Add support for the same.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information.

This also updates the devm_iio_device_alloc() call to consider the device object as the parent device by default. Having it passed like this, should ensure that any IIO device object already has a device object as parent, allowing for neater control, like passing the 'indio_dev' object for other stuff [like buffers/triggers/etc], and potentially creating iiom_xxx(indio_dev) functions. With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an update to pass the parent object as a parameter. In the next patch all devm_iio_device_alloc() calls will be handled.

In cases where devm_iio_device_alloc() is used, sometimes the parent device must be different than the device used to manage the allocation. In that case, this helper should be used to change the parent, hence the requirement to call this between allocation & registration. This pattern/requirement is not very common in the IIO space, and it may be cleaned up later. But until then, assigning the parent manually between allocation & registration is slightly easier.

This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

That makes things a bit more obvious about the new behavior of devm_iio_device_alloc() and makes it clearer that iio_device_set_parent() should be used.

There is a mix of trigger assignments with some iio device parent assignments that are removed via this patch. JC: A few more added via inspection of all parent = statements in drivers/iio. Some of these may just have crossed with this series, others were less obvious to scripting due to some cross file / module boundary calls.

This automatic assignment is done in the iio_device_register() function. There is a fair amount of drivers that currently manually assign the of_node of the IIO device. All but 4 of them can make use of the automatic assignment though. The exceptions are: * mxs-lradc-adc: Which uses the of_node of the parent of the parent. * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node assigned to the IIO device before iio_device_register() is called. All other drivers are updated to use automatic assignment. This reduces the amount of boilerplate code involved in setting up the IIO device. The patch has mostly been auto-generated with the following semantic patch // @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...) ... -indio_dev->dev.of_node = parent.of_node;

It used to work stably on x86 over years (and that's why we had enabled SG-buffer on solely x86) with the default mmap handler and vmap(), but our luck seems no forever success. The chance of breakage is high when the special DMA handling is introduced in the arch side. In this patch, we change the buffer allocation to use the SG-buffer only when the device in question is with the direct DMA. It's a bit hackish, but it's currently the only condition that may work (more or less) reliably with the default mmap and vmap() for mapping the pages that are deduced via virt_to_page(). In theory, we can apply the similar hack in the sound/core memory allocation helper, too; but it's used by SOF for allocating SG pages without re-mapping via vmap() or mmap, and it's fine to use it in that way, so let's keep it and adds the workaround in PCM side.

However, the source of time is different for both parameters: "busy_time" is assigned from "jiffies" thus has different accuracy from "total_time" which is assigned from ktime_get(). In addition, the time of window boundary is not exactly the same as the starting busy time in this window if UFS is actually busy in the beginning of the window. A similar accuracy error may also happen for the end of busy time in current window. To guarantee the precision of load calculation, we need to 1. Align time accuracy of both devfreq_dev_status.total_time and devfreq_dev_status.busy_time. For example, use "ktime_get()" directly. 2. Align the following timelines: - The beginning time of devfreq windows - The beginning of busy time in a new window - The end of busy time in the current window Link: https://lore.kernel.org/r/20200611101043.6379-1-stanley.chu@mediatek.com Fixes: a3cd5ec55f6c ("scsi: ufs: add load based scaling of UFS gear") Reviewed-by: Avri Altman Signed-off-by: Stanley Chu Signed-off-by: Martin K.

The two routines are able to handle data transfer to/from such a page in fragments and flush the cache after each fragment was copied by calling the wrapper tcmu_flush_dcache_range(). That means: 1) flush_dcache_page() can be called multiple times for the same page. 2) Calling flush_dcache_page() indirectly using the wrapper does not make sense, because each call of the wrapper is for one single page only and the calling routine already has the correct page pointer. Change (scatter|gather)_data_area() such that, instead of calling tcmu_flush_dcache_range() before/after each memcpy, it now calls flush_dcache_page() before unmapping a page (when writing is complete for that page) or after mapping a page (when starting to read the page). After this change only calls to tcmu_flush_dcache_range() for addresses in vmalloc'ed command ring are left over.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information.

Instead of doing this in each and every driver by hand move this into the core. At this point in time, all drivers should have been resolved to attach/detach the poll-function in the same order. This patch removes all explicit calls of iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() in all drivers, since the core handles now the pollfunc attach/detach. The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's not immediately obvious that removing the hooks doesn't break anything. Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board. All seems to be fine.

Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

These resources need to be properly released when removing a card, and this patch suggests a dual exit() callback. The exit() is invoked in soc_remove_pcm_runtime(), which is not completely symmetric with the init() invoked in soc_init_pcm_runtime(). Alternate solutions were considered, e.g. adding a .remove() callback for the platform driver, but that's not symmetrical at all and would be difficult to handle if there are more than one dailink implementing an .init(). We looked also into using .remove_dai_link() callback, but that would also be imbalanced. Note that because of the error handling in snd_soc_bind_card(), which jumps to probe_end, there is no way to guarantee the exit() is invoked with resources allocated in the init(). Prior to releasing those resources, implementations of the exit() callback shall check the resources are valid.

The BE dailink .init() function calls devm_gpiod_get() using the codec component device as argument. When the machine driver is removed, the references to the gpiod are not released, and it's not possible to remove the codec driver module - which is the only entity which could free the gpiod. This conceptual deadlock can be avoided by invoking gpiod_get() in the .init() callback, and calling gpiod_put() in the exit() callback. Tested on SAMUS Chromebook with SOF driver.

It enable drivers to return the entire device specific QP/CQ/MR context without a need from the driver to set each field separately. The raw query returns only the device specific data, general data is still returned by using the existing queries. Example: $ rdma res show mr dev mlx5_1 mrn 2 -r -j [{"ifindex":7,"ifname":"mlx5_1", "data":[0,4,255,254,0,0,0,0,0,0,0,0,16,28,0,216,...]}] Link: https://lore.kernel.org/r/20200623113043.1228482-9-leon@kernel.org Signed-off-by: Maor Gottlieb Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe --- drivers/infiniband/core/device.c | 3 + drivers/infiniband/core/nldev.c | 180 ++++++++++++++++++++----------- include/rdma/ib_verbs.h | 3 + include/uapi/rdma/rdma_netlink.h | 8 ++ 4 files changed, 132 insertions(+), 62 deletions(-) diff --git a/drivers/infiniband/core/device.c b/drivers/infiniband/core/device.c index cbe95e729cf10..1335ed1f1e4a2 100644 --- a/drivers/infiniband/core/device.c +++ b/drivers/infiniband/core/device.c @@ -2619,8 +2619,11 @@ void ib_set_device_ops(struct ib_device *dev, const struct ib_device_ops *ops) SET_DEVICE_OP(dev_ops, enable_driver);

We now have VCI_HALF_BRIGHT, VCI_NORMAL, and VCI_BOLD instead. Apart from the cleanup, 1) the enum allows for better type checking, and 2) this saves some code. No more fiddling with bits is needed in assembly now. (OTOH, the structure is larger.)

Switch it to bitmap and convert all users to the bitmap interface. Note the difference in behavior! We no longer mask the top 24 bits away from x, hence we do not wrap tabs at 256th column. Instead, we silently drop attempts to set a tab behind 256 columns. And we will also seek by '\t' to the rightmost column, when behind that boundary. I do not think the original behavior was desired and that someone relies on that. If this turns out to be the case, we can change the added 'if's back to masks here and there instead... (Or we can increase the limit as fb consoles now have 240 chars here. And they could have more with higher than my resolution, of course.)

Redefine all this to make some sense. In particular: * Drop CUR_DEFAULT, which is CUR_UNDERLINE. CUR_DEFAULT was used only for cur_default variable initialization, so use CUR_UNDERLINE there to make obvious what's the default. * Drop CUR_HWMASK. Instead, define CUR_SIZE() which explains it more. And use it all over the places. * Define few more masks and bits which will be used in next patches instead of magic constants. * Define CUR_MAKE to build up cursor value.

However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and dma_unmap_sg must be called with the original number of the entries passed to the dma_map_sg(). struct sg_table is a common structure used for describing a non-contiguous memory buffer, used commonly in the DRM and graphics subsystems. It consists of a scatterlist with memory pages and DMA addresses (sgl entry), as well as the number of scatterlist entries: CPU pages (orig_nents entry) and DMA mapped pages (nents entry). It turned out that it was a common mistake to misuse nents and orig_nents entries, calling DMA-mapping functions with a wrong number of entries or ignoring the number of mapped entries returned by the dma_map_sg() function. To avoid such issues, lets use a common dma-mapping wrappers operating directly on the struct sg_table objects and use scatterlist page iterators where possible. This, almost always, hides references to the nents and orig_nents entries, making the code robust, easier to follow and copy/paste safe.

Even when there is no playback happening, parts of the graph, specifically the IV sense->speaker protection->output remains active and this prevents the DSP from entering low-power states. This patch suggests a machine driver level approach where the speaker pins are enabled/disabled dynamically depending on stream start/stop events. DPAM graph representations show the feedback loop is indeed disabled and low-power states can be reached.

So to make life easier for the driver, move the rest of probe calls also to their devm-equivalents. This includes moving the clk- and regulator-disabling to a devm_action so that they gets disabled both during remove and in the error case in probe, after the action is registered.

This mechanism estimates device internal clock by comparing FIFO interrupts delta time and device elapsed time computed by parsing FIFO data. Take interrupt timestamp in hard irq handler and add IIO device specific timestamp structures in device private allocation.

Consequently, all set_mode() implementations in drivers: - can stop modifying tzd's "mode" member, - shall stop taking tzd's lock, as it is taken in the helpers - shall stop calling thermal_zone_device_update() as it is called in the helpers - can assume they are called when the mode truly changes, so checks to verify that can be dropped Not providing set_mode() by a driver no longer prevents the core from being able to set tzd's mode, so the relevant check in mode_store() is removed. Other comments: - acpi/thermal.c: tz->thermal_zone->mode will be updated only after we return from set_mode(), so use function parameter in thermal_set_mode() instead, no need to call acpi_thermal_check() in set_mode() - thermal/imx_thermal.c: regmap writes and mode assignment are done in thermal_zone_device_{en|dis}able() and set_mode() callback - thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a part of set_mode() callback, so they don't need to modify tzd->mode, and don't need to fall back to the opposite mode if unsuccessful, as the return value will be propagated to thermal_zone_device_{en|dis}able() and ultimately tzd's member will not be changed in thermal_zone_device_set_mode(). - thermal/of-thermal.c: no need to set zone->mode to DISABLED in of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway Signed-off-by: Andrzej Pietrasiewicz [for acerhdf] Acked-by: Peter Kaestle Reviewed-by: Amit Kucheria Reviewed-by: Bartlomiej Zolnierkiewicz Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20200629122925.21729-8-andrzej.p@collabora.com --- drivers/acpi/thermal.c | 21 ++++++----- .../ethernet/mellanox/mlxsw/core_thermal.c | 37 +++++++++---------- drivers/platform/x86/acerhdf.c | 17 +++++---- drivers/thermal/da9062-thermal.c | 6 ++- drivers/thermal/hisi_thermal.c | 6 ++- drivers/thermal/imx_thermal.c | 33 +++++++---------- .../intel/int340x_thermal/int3400_thermal.c | 5 +-- .../thermal/intel/intel_quark_dts_thermal.c | 18 ++------- drivers/thermal/rockchip_thermal.c | 6 ++- drivers/thermal/sprd_thermal.c | 6 ++- drivers/thermal/thermal_core.c | 2 +- drivers/thermal/thermal_of.c | 10 +---- drivers/thermal/thermal_sysfs.c | 11 ++---- 13 files changed, 80 insertions(+), 98 deletions(-) diff --git a/drivers/acpi/thermal.c b/drivers/acpi/thermal.c index 592be97c4456d..52b6cda1bcc30 100644 --- a/drivers/acpi/thermal.c +++ b/drivers/acpi/thermal.c @@ -499,7 +499,7 @@ static void acpi_thermal_check(void *data) { struct acpi_thermal *tz = data; - if (tz->thermal_zone->mode != THERMAL_DEVICE_ENABLED) + if (!thermal_zone_device_is_enabled(tz->thermal_zone)) return; thermal_zone_device_update(tz->thermal_zone, @@ -542,14 +542,11 @@ static int thermal_set_mode(struct thermal_zone_device *thermal, if (mode == THERMAL_DEVICE_DISABLED) pr_warn("thermal zone will be disabled\n"); - if (mode != tz->thermal_zone->mode) { - tz->thermal_zone->mode = mode; - ACPI_DEBUG_PRINT((ACPI_DB_INFO, - "%s kernel ACPI thermal control\n", - tz->thermal_zone->mode == THERMAL_DEVICE_ENABLED ?

The fix is to use the minimum of remaining ring space and sizeof(struct tcmu_cmd_entry) as the length param. The patch was tested on kernel 4.19.118.

This passes __GFP_NOWARN to kmalloc_array to avoid unnecessary user- triggered WARN_ON. Note that the error is not ignored and the warning is still printed.

Let's get rid of this opaque structure and directly pass struct vchiq_header, which is what ultimately vchiq consumes when handling callback messages.

The pcm3168a SCKI clock is coming via the j721e AUDIO_REFCLK2 pin. In order to support 48KHz and 44.1KHz family of sampling rates the parent clock for AUDIO_REFCLK2 needs to be changed between PLL4 (for 48KHz) and PLL15 (for 44.1KHz). The same PLLs are used for McASP10's AUXCLK clock via different HSDIVIDER. Generic card can not be used for the board as we need to switch between clock paths for different sampling rate families and also need to change the slot_width between 16 and 24 bit audio. The audio support on the Infotainment Expansion Board consists of McASP0 connected to two pcm3168a codecs with dedicated set of serializers to each. The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin. It is extending the audio support on the CPB. Due to the fact that the same PLL4/15 is used by both domains (CPB/IVI) there are cross restriction on sampling rates. The IVI side is represented as multicodec setup. PCMs available on a plain CPB (no IVI addon): hw:0,0 - cpb playback (8 channels) hw:0,1 - cpb capture (6 channels) When the IVI addon is present, additional two PCMs will be present: hw:0,2 - ivi multicodec playback (16 channels) hw:0,3 - ivi multicodec capture (12 channels) Signed-off-by: Peter Ujfalusi Link: https://lore.kernel.org/r/20200630125843.11561-4-peter.ujfalusi@ti.com Signed-off-by: Mark Brown --- sound/soc/ti/Kconfig | 8 + sound/soc/ti/Makefile | 2 + sound/soc/ti/j721e-evm.c | 896 +++++++++++++++++++++++++++++++++++++++ 3 files changed, 906 insertions(+) create mode 100644 sound/soc/ti/j721e-evm.c diff --git a/sound/soc/ti/Kconfig b/sound/soc/ti/Kconfig index c5408c129f342..53df545efe0ad 100644 --- a/sound/soc/ti/Kconfig +++ b/sound/soc/ti/Kconfig @@ -219,5 +219,13 @@ config SND_SOC_DM365_VOICE_CODEC_MODULE The is an internal symbol needed to ensure that the codec and MFD driver can be built as loadable modules if necessary. +config SND_SOC_J721E_EVM + tristate "SoC Audio support for j721e EVM" + depends on ARCH_K3_J721E_SOC || COMPILE_TEST + select SND_SOC_PCM3168A_I2C + select SND_SOC_DAVINCI_MCASP + help + Say Y if you want to add support for SoC audio on j721e Common + Processor Board and Infotainment expansion board. endmenu diff --git a/sound/soc/ti/Makefile b/sound/soc/ti/Makefile index ea48c6679cc72..a21e5b0061de3 100644 --- a/sound/soc/ti/Makefile +++ b/sound/soc/ti/Makefile @@ -34,6 +34,7 @@ snd-soc-omap-abe-twl6040-objs := omap-abe-twl6040.o snd-soc-ams-delta-objs := ams-delta.o snd-soc-omap-hdmi-objs := omap-hdmi.o snd-soc-osk5912-objs := osk5912.o +snd-soc-j721e-evm-objs := j721e-evm.o obj-$(CONFIG_SND_SOC_DAVINCI_EVM) += snd-soc-davinci-evm.o obj-$(CONFIG_SND_SOC_NOKIA_N810) += snd-soc-n810.o @@ -44,3 +45,4 @@ obj-$(CONFIG_SND_SOC_OMAP_ABE_TWL6040) += snd-soc-omap-abe-twl6040.o obj-$(CONFIG_SND_SOC_OMAP_AMS_DELTA) += snd-soc-ams-delta.o obj-$(CONFIG_SND_SOC_OMAP_HDMI) += snd-soc-omap-hdmi.o obj-$(CONFIG_SND_SOC_OMAP_OSK5912) += snd-soc-osk5912.o +obj-$(CONFIG_SND_SOC_J721E_EVM) += snd-soc-j721e-evm.o diff --git a/sound/soc/ti/j721e-evm.c b/sound/soc/ti/j721e-evm.c new file mode 100644 index 0000000000000..3a2a8b1f3aa37 --- /dev/null +++ b/sound/soc/ti/j721e-evm.c @@ -0,0 +1,896 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Copyright (C) 2020 Texas Instruments Incorporated - http://www.ti.com + * Author: Peter Ujfalusi + */ + +#include +#include +#include +#include + +#include +#include +#include +#include + +#include "davinci-mcasp.h" + +/* + * Maximum number of configuration entries for prefixes: + * CPB: 2 (mcasp10 + codec) + * IVI: 3 (mcasp0 + 2x codec) + */ +#define J721E_CODEC_CONF_COUNT 5 + +#define J721E_AUDIO_DOMAIN_CPB 0 +#define J721E_AUDIO_DOMAIN_IVI 1 + +#define J721E_CLK_PARENT_48000 0 +#define J721E_CLK_PARENT_44100 1 + +#define J721E_MAX_CLK_HSDIV 128 +#define PCM1368A_MAX_SYSCLK 36864000 + +#define J721E_DAI_FMT (SND_SOC_DAIFMT_RIGHT_J | \ + SND_SOC_DAIFMT_NB_NF | \ + SND_SOC_DAIFMT_CBS_CFS) + +enum j721e_board_type { + J721E_BOARD_CPB = 1, + J721E_BOARD_CPB_IVI, +};

Thus the flush inside ipoib_flush_ah() will deadlock if it gets unlucky enough, and lockdep doesn't help us to find it early: CPU0 CPU1 CPU2 __ipoib_ib_dev_flush() down_read(vlan_rwsem) ipoib_vlan_add() rtnl_trylock() down_write(vlan_rwsem) ipoib_mcast_carrier_on_task() while (!rtnl_trylock()) msleep(20); ipoib_flush_ah() flush_workqueue(priv->wq) Clean up the ah_reaper related functions and lifecycle to make sense: - Start/Stop of the reaper should only be done in open/stop NDOs, not in any other places - cancel and flush of the reaper should only happen in the stop NDO. cancel is only functional when combined with IPOIB_STOP_REAPER. - Non-stop places were flushing the AH's just need to flush out dead AH's synchronously and ignore the background task completely. It is fully locked and harmless to leave running. Which ultimately fixes the ABBA deadlock by removing the unnecessary flush_workqueue() from the problematic place under the vlan_rwsem.

The failing NVMe array supports concurrent FCP and NVMe operation via different nport_id's. The array was repeatedly sending an ADISC every 2 seconds after PLOGI completed and while NVMe subsystems were executing discovery. The target would continue this state for roughly 45 seconds. The driver's current behavior on ADISC receipt is to validate a the ADISC vs the device and issue a RESUME_RPI to restore transmission. The receipt of the ADISC effectively caused a driver to take actions similar to a logout and login for the remote port, causing the deregistration of the nvme rport and a subsequent re-registration. This caused a constant reset and re-connect of the NVMe controller while this 45s window occurred. There was no need for the state changes as ADISC does not change login state. This patch corrects this behavior by validating if the remoteport is already logged in (MAPPED) and when true, avoids the call to set the ndlp state to MAPPED, which triggers the unreg/re-reg. Thus ADISC does not change the login state of the node.

There is a shost reference taken in scsi_add_host_dma that is not released during scsi_remove_host. It was noticed that other drivers resolve this by doing a scsi_host_put after calling scsi_remove_host. The vport_delete routine is taking two references one that corresponds to an access to the scsi_host in the vport_delete routine and another that is released after the adapter mailbox command completes that destroys the VPI that corresponds to the vport. Remove one of the references taken such that the second reference that is put will complete the missing scsi_add_host_dma reference and the shost will be terminated.

Other tasks in the system can delay handling. Change the lower level to use irq_poll by default which uses a softirq for I/O completion. This gives better latency as variance in when the cq is processed is reduced over the workqueue interface. However, as high load is better served by not being in softirq when the CPU is loaded, work queues are still used under high I/O load.

This was mainly by design to not clutter the kernel log messages with things that were typically not interesting and the messages themselves could cause other issues. When looking to make a better system, it was seen that in many cases when more data was wanted was when another message, usually at KERN_ERR level, was logged. And in most cases, what the additional logging that was then enabled was typically. Most of these areas fell into the discovery machine. Based on this summary, the following design has been put in place: The driver will maintain an internal log (256 elements of 256 bytes). The "additional logging" messages that are usually enabled in a reproduction will be changed to now log all the time to the internal log. A new logging level is defined - LOG_TRACE_EVENT. When this level is set (it is not by default) and a message marked as KERN_ERR is logged, all the messages in the internal log will be dumped to the kernel log before the KERN_ERR message is logged. There is a timestamp on each message added to the internal log. However, this timestamp is not converted to wall time when logged. The value of the timestamp is solely to give a crude time reference for the messages.

In this case, there is only one vif identifier for all the confirmations. Unfortunately, to generate this kind of messages the device squashes all the confirmations whatever their vif ID and use the vif ID of the first confirmation. So, the driver cannot rely on the vif ID mentioned in the header. Fortunately, using the packet_id, the driver can retrieve the Tx request and the associated vif.

So, neither the driver, neither the hardware buffer the frames. So the call to ieee80211_sta_set_buffered is useless. In add, it seems that mac80211 does not expect to receive ieee80211_sta_set_buffered(false) after the station is asleep(). When the device send data to a station, the following sequence can be observed: - Mac80211 call wfx_sta_notify(awake). - The driver calls ieee80211_sta_set_buffered(true). Since the station is awake, its TIM is not set. - Mac80211 receive a power save notification from the station, so it calls wfx_sta_notify(asleep). - Then, since the driver has declared it has buffered some frames, the TIM of the station should be set. This action is delayed by mac80211. - The device also notice the station go to sleep. It replies the REQUEUE status for the buffered frames. The driver forward this status to mac80211. - There is no more frames in queues, so the driver call ieee80211_sta_set_buffered(false). - Mac80211 updates the TIM but since there is no frames buffered by the driver, it set the TIM for the station to 0. Anyway, correctly use the ieee80211_sta_set_buffered() API solves the problem.

In add, the problem seems now fixed in the firmware (at least, it has not been encountered with recent firmwares).

However, the device is not able to re-order the frames during BlockAck sessions. Mac80211 is able to reorder the frames, but it need the information about the BlockAck sessions start and stop. Unfortunately, since the BlockAck is fully handled by the hardware, these frames were not forwarded to the host. So, if the driver ask to mac80211 to apply the replay protection, it drop all misordered frames. So, until now, the driver explicitly asked to mac80211 to not apply the CCMP/TKIP replay protection. The situation has changed with the API 3.4 of the device firmware. The firmware forward the BlockAck information. Mac80211 is now able to correctly reorder the frames. There is no more reasons to drop cryptographic data. This patch also impact the older firmwares. There will be a performance impact on these firmware (since the misordered frames will dropped). However, we can't keep the replay protection disabled.

IEC61937 data. These two steps take time and up to 2-3 seconds of audio may be muted when starting playback. Intel hardware (Haswell and beyond) can keep the link active with a 'silent stream', so that the receiver does not go through those two steps when valid audio is transmitted. This mechanism relies on an setting the channel_id as 0xf, sending info packet and preventing the codec from going to D3, which will increase the platform static power consumption. The info packet assumes a basic 2ch stereo, and the silent stream is enabled when connecting a monitor. In case of format changes the detection of PCM v. IEC61937 needs to be re-run. In this case there is no way to avoid the 2-3s mute. The silent stream is enabled with a Kconfig option, as well as a kernel parameter should there be a need to override the build time default. This approach is used based on the power_save capability as an example, but in the future, it may be used with a kcontrol, depending on UCM support for HDaudio legacy.

The notification function was never called from anywhere and the corresponding dead code was removed. It was probably a first attempt to introduce the netlink notification. At LPC2018, the presentation "Linux thermal: User kernel interface", proposed to create the notifications to the userspace via a kfifo. The advantage of the kfifo is the performance. It is usually used from a 1:1 communication channel where a driver captures data and sends it as fast as possible to a userspace process. The drawback is that only one process uses the notification channel exclusively, thus no other process is allowed to use the channel to get temperature or notifications. This patch defines a generic netlink API to discover the current thermal setup and adds event notifications as well as temperature sampling. As any genetlink protocol, it can evolve and the versioning allows to keep the backward compatibility. In order to prevent the user from getting flooded with data on a single channel, there are two multicast channels, one for the temperature sampling when the thermal zone is updated and another one for the events, so the user can get the events only without the thermal zone temperature sampling. Also, a list of commands to discover the thermal setup is added and can be extended when needed.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information, and also keeping a reference to the iio device for some quirky paths. One [quirky] path is the at91_adc_workq_handler() which requires the IIO device & the state struct to push to buffers. Since this requires the back-ref to the IIO device, the at91_adc_touch_pos() also uses it. This simplifies the patch a bit. The information required in this function is mostly for debugging purposes. Replacing it with a reference to the IIO device would have been a slightly bigger change, which may not be worth it (for just the debugging purpose and given that we need the back-ref to the IIO device anyway).

Sometimes users copy drivers that are not always the best examples. A better idea is to hide those fields into the framework. For 'struct iio_dev' this is a 'struct iio_dev_opaque' which wraps a public 'struct iio_dev' object. In the next series, some fields will be moved to this new struct, each with it's own rework. This rework will not be complete-able for a while, as many fields need some drivers to be reworked in order to finalize them (e.g. 'indio_dev->mlock'). But some fields can already be moved, and in time, all of them may get there (in the 'struct iio_dev_opaque' object). Since a lot of drivers also call 'iio_priv()', in order to preserve fast-paths (where this matters), the public iio_dev object will have a 'priv' field that will have the pointer to the private information already computed. The reference returned by this field should be guaranteed to be cacheline aligned. The opaque parts will be moved into the 'include/linux/iio/iio-opaque.h' header. Should the hidden information be required for some debugging or some special needs, it can be made available via this header. Otherwise, only the IIO core files should include this file.

So when we get to the bottom of core_scsi3_decode_spec_i_port the pr_reg_deve is NULL and we crash when trying to access the local_pr_reg's pr_reg_deve. We've also done an extra undepend for local_pr_reg and if we didn't crash on the NULL we would have done an extra kref_put too. This patch has us do a core_scsi3_lunacl_depend_item for local_pr_reg and then let __core_scsi3_add_registration handle the cleanup for the pr_reg_deve. We then just skip the undepend for the acl and tpg for the local pr_reg. The error path then works in a similar way, but we always do the core_scsi3_lunacl_undepend_item since we never call __core_scsi3_add_registration in that code path.

There's a theoretical race where zfcp_qdio_int_req() completes a number of SBALs & increments the queue's free-level _before_ zfcp_qdio_send() was able to decrement it. This can cause ->req_q_free to momentarily hold a value larger than QDIO_MAX_BUFFERS_PER_Q. Luckily zfcp_qdio_send() is always called under ->req_q_lock, and all readers of the free-level also take this lock. So we can trust that zfcp_qdio_send() will clean up such a temporary overflow before anyone can actually observe it. But it's still confusing and annoying to worry about. So adjust the code to avoid this race.

Many existing inline crypto devices require some additional behaviour not specified in the UFSHCI v2.1 specification - as such the vendor specific drivers will need to be updated where necessary to make it possible to use those devices. Some of these changes have already been proposed upstream, such as for the Qualcomm 845 SoC at https://lkml.kernel.org/linux-scsi/20200501045111.665881-1-ebiggers@kernel.org/ and for ufs-mediatek at https://lkml.kernel.org/linux-scsi/20200304022101.14165-1-stanley.chu@mediatek.com/ This patch has been tested on the db845c, sm8150-mtp and sm8250-mtp (which have Qualcomm chipsets) and on some mediatek chipsets using these aforementioned vendor specific driver updates.

CPUs. The driver is currently assuming exclusivity and vectors being doled out to different CPUs and is assigning primary ownership of each vector to the first CPU in the mask. The code doesn't bother to check if the CPU already owns a vector and will unconditionally overwrite the CPU to vector mapping. This causes the relationships between eq's and cq's to get confused and gets worse when CPUs start to offline. The net results are interrupts are skipped resulting in mailbox timeouts and there are oopses in CPU offling flows. Fix this changing up the primary vector assignment. Now assign the eq to a CPU only if it is the CPU in the mask that does not have a prior assignment. And once the primary ownership is assigned, break from the loop. For CPUs that may have been set before but not the primary owner, the lpfc_cpu_affinity_check() routine will balance the CPU to eq assignment.

The ignore_msrs was previously handled by kvm_get_msr_common() and kvm_set_msr_common(), which is the bottom of the msr access stack. It's working in most cases, however it could dump unwanted warning messages to dmesg even if kvm get/set the msrs internally when calling __kvm_set_msr() or __kvm_get_msr() (e.g. kvm_cpuid()). Ideally we only want to trap cases (2) or (3), but not (1) above. To achieve this, move the ignore_msrs handling upper until the callers of __kvm_get_msr() and __kvm_set_msr(). To identify the "msr missing" event, a new return value (KVM_MSR_RET_INVALID==2) is used for that.

This will not cause any symptoms, but it is misleading. Fix this by changing the type of npinned to "int". 2) The number of pages passed into get_user_pages_fast() is stored in an unsigned long, even though get_user_pages_fast() accepts an int. This means that it is possible to silently overflow the number of pages. Fix this by adding a WARN_ON_ONCE() and an early error return. The npages variable is left as an unsigned long for convenience in checking for overflow.

This fixes a long standing issue where KVM's shrinker implementation is completely ineffective due to zapping only a single page. E.g. without batch zapping, forcing a scan via drop_caches basically has no impact on a VM with ~2k shadow pages. With batch zapping, the number of shadow pages can be reduced to a few hundred pages in one or two runs of drop_caches. Note, if the default batch size (currently 128) is problematic, e.g. zapping 128 pages holds mmu_lock for too long, KVM can bound the batch size by setting @batch in mmu_shrinker.

The best way I have found to reproduce the bug is to use dmix in combination with Chromium, which opens the audio device multiple times in threads. Anecdotally, the problems appear to have increased with faster CPUs. I ruled out 32-bit counter wrapping; it often happens much earlier. Since applying this patch I have not had problems, where previously they would occur several times a day. The patch targets the following issues: * Check for progress using the counter from the hardware, not after it has been truncated to the buffer. This is a clean way to address a possible bug where if a whole ringbuffer advances between interrupts, it goes unnoticed. * Move last_period state from chip to pipe This more logically belongs as part of pipe, and code is reasier to read if it is "counter position last time a period elapsed". Now the code has no references to period count. A period is just when the regular counter crosses a threshold. This increases readability and reduces scope for bugs. * Treat period notification and buffer advance independently: This helps to clarify what is the responsibility of the interrupt handler, and what is pcm_pointer(). Removing shared state between these operations means race conditions are fixed without introducing locks. Synchronisation is only around the read of pipe->dma_counter. There may be cache line contention around "struct audiopipe" but I did not have cause to profile this. Pay attention to be robust where dma_counter wrapping is not a multiple of period_size or buffer_size. This is a revised patch based on feedback from Takashi and Giuliano.

Currently, kvm_update_cpuid_runtime() only updates CPUID bits of OSXSAVE, APIC, OSPKE, MWAIT, KVM_FEATURE_PV_UNHALT and CPUID(0xD,0).ebx and CPUID(0xD, 1).ebx. None of them is consumed by vmx/svm's update_vcpu_after_set_cpuid(). So there is no dependency between them.

One such case is when host CPU supports STIBP mitigation but doesn't support IBRS (as is the case with some Zen2 AMD cpus), and in this case we were giving guest #GP when it tried to use STIBP The reason why can can do the host test is that IA32_SPEC_CTRL msr is passed to the guest, after the guest sets it to a non zero value for the first time (due to performance reasons), and as as result of this, it is pointless to emulate #GP condition on this first access, in a different way than what the host CPU does. This is based on a patch from Sean Christopherson, who suggested this idea.

This uses wrmsrl() which is interesting at least. wrmsrl() is either using native_write_msr() or the paravirt variant. The XEN_PV code is uninteresting as nested SVM in a XEN_PV guest does not work. But native_write_msr() can be placed out of line by the compiler especially when paravirtualization is enabled in the kernel configuration. The function is marked notrace, but still can be probed if CONFIG_KPROBE_EVENTS_ON_NOTRACE is enabled. That would be a fatal problem as kprobe events use per-CPU variables which are GS based and would be accessed with the guest GS. Depending on the GS value this would either explode in colorful ways or lead to completely undebugable data corruption. Aside of that native_write_msr() contains a tracepoint which objtool complains about as it is invoked from the noinstr section. As this cannot run inside a XEN_PV guest there is no point in using wrmsrl(). Use native_wrmsrl() instead which is just a plain native WRMSR without tracing or anything else attached.

Now that encountering an empty cache is unlikely to trigger BUG_ON(), it is less dangerous to be more precise when defining the minimums. For rmaps, the logic is 1 parent PTE per level, plus a single rmap, and prefetched rmaps. The extra objects in the current '8 + PREFETCH' minimum came about due to an abundance of paranoia in commit c41ef344de212 ("KVM: MMU: increase per-vcpu rmap cache alloc size"), i.e. it could have increased the minimum to 2 rmaps. Furthermore, the unexpected extra rmap case was killed off entirely by commits f759e2b4c728c ("KVM: MMU: avoid pte_list_desc running out in kvm_mmu_pte_write") and f5a1e9f89504f ("KVM: MMU: remove call to kvm_mmu_pte_write from walk_addr"). For the so called page cache, replace '8' with 2*PT64_ROOT_MAX_LEVEL. The 2x multiplier is needed because the cache is used for both shadow pages and gfn arrays for indirect MMUs. And finally, for page headers, replace '4' with PT64_ROOT_MAX_LEVEL. Note, KVM now supports 5-level paging, i.e. the old minimums that used a baseline derived from 4-level paging were technically wrong. But, KVM always allocates roots in a separate flow, e.g. it's impossible in the current implementation to actually need 5 new shadow pages in a single flow. Use PT64_ROOT_MAX_LEVEL unmodified instead of subtracting 1, as the direct usage is likely more intuitive to uninformed readers, and the inflated minimum is unlikely to affect functionality in practice.

For historical reasons, many kvm-related function parameters retain the 'kvm_run' and 'kvm_vcpu' parameters at the same time. This patch does a unified cleanup of these remaining redundant parameters.

But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary.

Using generic kvm_set_cr3() when switching to nested guest is not a great idea as we'll have to distinguish between 'real' CR3s and 'nested' CR3s to e.g. not call kvm_mmu_new_pgd() with nGPA. Following nVMX implement nested-specific nested_svm_load_cr3() doing the job. To support the change, nested_svm_load_cr3() needs to be re-ordered with nested_svm_init_mmu_context(). Note: the current implementation is sub-optimal as we always do TLB flush/MMU sync but this is still an improvement as we at least stop doing kvm_mmu_reset_context().

Until IceLake introduced MAXPHYADDR==52, running on a machine with higher MAXPHYADDR than the guest more or less worked, because software that relied on reserved address bits (like KVM) generally used bit 51 as a marker and therefore the page faults where generated anyway. Unfortunately this is not true anymore if the host MAXPHYADDR is 52, and this can cause problems when migrating from a MAXPHYADDR<52 machine to one with MAXPHYADDR==52. Typically, the latter are machines that support 5-level page tables, so they can be identified easily from the LA57 CPUID bit. When that happens, the guest might have a physical address with reserved bits set, but the host won't see that and trap it. Hence, we need to check page faults' physical addresses against the guest's maximum physical memory and if it's exceeded, we need to add the PFERR_RSVD_MASK bits to the page fault error code. This patch does this for the MMU's page walks. The next patches will ensure that the correct exception and error code is produced whenever no host-reserved bits are set in page table entries.

If the guest's physical address exceeds the maximum (i.e. has reserved bits set), inject a guest page fault with PFERR_RSVD_MASK set. This has to be done both in the EPT violation and page fault paths, as there are complications in both cases with respect to the computation of the correct error code. For EPT violations, unfortunately the only possibility is to emulate, because the access type in the exit qualification might refer to an access to a paging structure, rather than to the access performed by the program. Trapping page faults instead is needed in order to correct the error code, but the access type can be obtained from the original error code and passed to gva_to_gpa. The corrections required in the error code are subtle. For example, imagine that a PTE for a supervisor page has a reserved bit set. On a supervisor-mode access, the EPT violation path would trigger. However, on a user-mode access, the processor will not notice the reserved bit and not include PFERR_RSVD_MASK in the error code.

If SVM is modified to add guest physical address checks in the NPF and guest #PF paths, we see the followning error multiple times in the 'access' test in kvm-unit-tests: test pte.p pte.36 pde.p: FAIL: pte 2000021 expected 2000001 Dump mapping: address: 0x123400000000 ------L4: 24c3027 ------L3: 24c4027 ------L2: 24c5021 ------L1: 1002000021 This is because the PTE's accessed bit is set by the CPU hardware before the NPF vmexit. This is handled completely by hardware and cannot be fixed in software. Therefore, availability of the new capability depends on a boolean variable allow_smaller_maxphyaddr which is set individually by VMX and SVM init routines. On VMX it's always set to true, on SVM it's only set to true when NPT is not enabled.

Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Normally this unique tag will be in the range [0, max queue], where "max queue" is the depth of each of the submission queues. Add support for this hostwide tag feature, via module parameter "host_max_queue". A non-zero value means that the feature is enabled. In this case, the submission queues are not exposed to upper layer, i.e. from blk-mq prespective, the device has a single hw queue. There are 2 reasons for this: a. It is assumed that the host can support nr_hw_queues * can_queue commands, but this is not true for hostwide tags b. For nr_hw_queues != 0, the request tag is not unique over all HW queues, and some HBA drivers want to use this tag for the hostwide tag However, like many SCSI HBA drivers today - megaraid sas being an example - the full set of HW submission queues are still used in the LLDD driver. So instead of using a complicated "reply_map" to create a per-CPU submission queue mapping like megaraid_sas (as it depends on a PCI device + MSIs) - use a simple algorithm: hwq = cpu % queue count If the host_max_queue param is set non-zero, then the max queue depth is fixed at this value also. If and when hostwide shared tags are supported in blk-mq/scsi mid-layer, then the policy to set nr_hw_queues = 0 for hostwide tags can be revised.

Here is a list of 'opts' flags and in which cases they inject errors when abs(every_nth)%command_count == 0 is reached: - OPT_RECOVERED_ERR: issued on READ(*)s, WRITE(*)s and WRITE_SCATTEREDs - OPT_DIF_ERR: issued on READ(*)s, WRITE(*)s and WRITE_SCATTEREDs - OPT_DIX_ERR: issued on READ(*)s, WRITE(*)s and WRITE_SCATTEREDs - OPT_SHORT_TRANSFER: issued on READ(*)s - OPT_TRANSPORT_ERR: issued on all commands - OPT_CMD_ABORT: issued on all commands The other uses of every_nth were not modified. Previously if, for example, OPT_SHORT_TRANSFER was armed then if (abs(every_nth) % command_count == 0) occurred during a command that was _not_ a READ, then no error injection occurred. This behaviour puzzled several testers. Now a global "inject_pending" flag is set and the _next_ READ will get hit and that flag is cleared. OPT_RECOVERED_ERR, OPT_DIF_ERR and OPT_DIX_ERR have similar behaviour. A downside of this is that there might be a hang-over pending injection that gets triggered by a following test. Also expand the every_nth runtime parameter so that it can take hex value (i.e. with a leading '0x') as well as a decimal value. Now both the 'opts' and the 'every_nth' runtime parameters can take hexadecimal values.

After looking through the discussion logs (on email), it seems that this order was wrong for the start, even though the order implemented in the drivers was correct. Discussions: - first RFC: https://lore.kernel.org/linux-iio/20180622135322.3459-1-alexandru.ardelean@analog.com/ - 2nd patch: https://lore.kernel.org/linux-iio/20181219140912.22582-1-alexandru.ardelean@analog.com/ - final patch-sets: https://lore.kernel.org/linux-iio/20200522104632.517470-1-alexandru.ardelean@analog.com/ https://lore.kernel.org/linux-iio/20200525113855.178821-1-alexandru.ardelean@analog.com/ The last one was applied. The idea is that pollfunc should be attached before calling the 'indio_dev->setup_ops->postenable' hook and should be detached after calling the 'indio_dev->setup_ops->predisable' hook. While the drivers were updated to take this into account, the change to the IIO core was somehow omitted and was made wrong. This change fixes the order to the proper form.

For example, every successful vfs_write() hits fsnotify_modify which calls both fsnotify_parent and fsnotify unless FMODE_NONOTIFY is set which is an internal flag invisible to userspace. As it stands, fsnotify_parent is a guaranteed functional call even if there are no watchers and fsnotify() does a substantial amount of unnecessary work before it checks if there are any watchers. A perf profile showed that applying mnt->mnt_fsnotify_mask in fnotify() was almost half of the total samples taken in that function during a test. This patch rearranges the fast paths to reduce the amount of work done when there are no watchers. The test motivating this was "perf bench sched messaging --pipe". Despite the fact the pipes are anonymous, fsnotify is still called a lot and the overhead is noticeable even though it's completely pointless. It's likely the overhead is negligible for real IO so this is an extreme example. This is a comparison of hackbench using processes and pipes on a 1-socket machine with 8 CPU threads without fanotify watchers. 5.7.0 5.7.0 vanilla fastfsnotify-v1r1 Amean 1 0.4837 ( 0.00%) 0.4630 * 4.27%* Amean 3 1.5447 ( 0.00%) 1.4557 ( 5.76%) Amean 5 2.6037 ( 0.00%) 2.4363 ( 6.43%) Amean 7 3.5987 ( 0.00%) 3.4757 ( 3.42%) Amean 12 5.8267 ( 0.00%) 5.6983 ( 2.20%) Amean 18 8.4400 ( 0.00%) 8.1327 ( 3.64%) Amean 24 11.0187 ( 0.00%) 10.0290 * 8.98%* Amean 30 13.1013 ( 0.00%) 12.8510 ( 1.91%) Amean 32 13.9190 ( 0.00%) 13.2410 ( 4.87%) 5.7.0 5.7.0 vanilla fastfsnotify-v1r1 Duration User 157.05 152.79 Duration System 1279.98 1219.32 Duration Elapsed 182.81 174.52 This is showing that the latencies are improved by roughly 2-9%. The variability is not shown but some of these results are within the noise as this workload heavily overloads the machine. That said, the system CPU usage is reduced by quite a bit so it makes sense to avoid the overhead even if it is a bit tricky to detect at times. A perf profile of just 1 group of tasks showed that 5.14% of samples taken were in either fsnotify() or fsnotify_parent(). With the patch, 2.8% of samples were in fsnotify, mostly function entry and the initial check for watchers. The check for watchers is complicated enough that inlining it may be controversial.

The lpfc driver is currently not doing so, although it is implementing a driver internal node loss value of 30s which also is used on the SCSI FC remote port. As no devloss_tmo is set, the nvme-fc transport defaults to 60s. So there are competing timers. Additionally, due to the competing timers, it is possible the NVMe rport is removed but the SCSI rport remains. It is possible that the SCSI FC rport, which was registered for the NVMe port even if it doesn't utilize the SCSI protocol, had been tuned to not match either the 60s (nvme-fc default) or 30s (lldd default), it gets out of whack. The lldd will defer to the SCSI FC rport as long as the SCSI FC rport has not had its devloss_tmo expire. Correct the situation by specifying a default devloss_tmo to the nvme-fc transport when registering the rport. Take the value from the SCSI FC rport if it exists, otherwise use the driver default.

This patch adds the qedr <-> libqedr interface so that the libqedr can set the flag appropriately and qedr can pass it down to FW. Flag is added for backward compatibility with libqedr. For older libs, this flag didn't exist and therefore set to zero.

The SADC component in JZ47xx SoCs provides support for touchscreen operations (pen position and pen down pressure) in single-ended and differential modes. The touchscreen component of SADC takes a significant time to stabilize after first receiving the clock and a delay of 50ms has been empirically proven to be a safe value before data sampling can begin. Of the known hardware to use this controller, GCW Zero and Anbernic RG-350 utilize the touchscreen mode by having their joystick(s) attached to the X/Y positive/negative input pins. JZ4770 and later SoCs introduce a low-level command feature. With it, up to 32 commands can be programmed, each one corresponding to a sampling job. It allows to change the low-voltage reference, the high-voltage reference, have them connected to VCC, GND, or one of the X-/X+ or Y-/Y+ pins. This patch introduces support for 6 stream-capable channels: - channel #0 samples X+/GND - channel #1 samples Y+/GND - channel #2 samples X-/GND - channel #3 samples Y-/GND - channel #4 samples X+/X- - channel #5 samples Y+/Y- Being able to sample X-/GND and Y-/GND is useful on some devices, where one joystick is connected to the X+/Y+ pins, and a second joystick is connected to the X-/Y- pins. All the boards which probe this driver have the interrupt provided from Device Tree, with no need to handle a case where the IRQ was not provided.

Two functions of the counter are supported for the moment: period capture and quadrature decoder. The latter is only supported by the SAMA5 series of SoCs. For the period capture mode a basic setup has been chosen that will reset the counter each time the period is actually reached. Of course the device offers much more possibilities. For quadrature mode, both channel 0 and 1 must be configured even if we only capture the position (no revolution/rotation).

This workqueue is flushed while the SPI subsystem is working in some other system workqueue. The system workqueue is marked as WQ_MEM_RECLAIM, but the workqueue in the lantiq-ssc driver does not use WQ_MEM_RECLAIM for now. Add this flag too to prevent this warning.

This patch exports an inline function tegra_set_cif() which can be used, for now, to program CIF on Tegra210 and later Tegra generations. Later it can be extended to include helpers for legacy chips as well.

The DMIC controller implements a converter to convert PDM signals to Pulse Code Modulation (PCM) signals. From signal flow perspective, the DMIC can be viewed as a PDM receiver. This patch registers DMIC component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes DMIC interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The DMIC devices can be enabled in the DT via "nvidia,tegra210-dmic" compatible string. This driver can be used for Tegra186 and Tegra194 chips as well.

It can interface with I2S compatible devices. Tegra I2S controller can operate as both master and slave. This patch registers I2S controller with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes I2S interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The I2S devices can be enabled in the DT via "nvidia,tegra210-i2s" compatible binding.

AHUB supports multiple interfaces to I2S, DSPK, DMIC etc., XBAR is a switch used to configure or modify audio routing between HW accelerators present inside AHUB. This patch registers AHUB component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes AHUB interfaces, which can be used to connect different components in the ASoC layer. Currently the driver takes care of XBAR programming to allow audio data flow through various clients of the AHUB. Makefile and Kconfig support is added to allow to build the driver. The AHUB component can be enabled in the DT via below compatible bindings. - "nvidia,tegra210-ahub" for Tegra210 - "nvidia,tegra186-ahub" for Tegra186 and Tegra194 Signed-off-by: Sameer Pujar Link: https://lore.kernel.org/r/1595134890-16470-6-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown --- sound/soc/tegra/Kconfig | 10 + sound/soc/tegra/Makefile | 2 + sound/soc/tegra/tegra210_ahub.c | 676 ++++++++++++++++++++++++++++++++ sound/soc/tegra/tegra210_ahub.h | 127 ++++++ 4 files changed, 815 insertions(+) create mode 100644 sound/soc/tegra/tegra210_ahub.c create mode 100644 sound/soc/tegra/tegra210_ahub.h diff --git a/sound/soc/tegra/Kconfig b/sound/soc/tegra/Kconfig index 52ec1add69524..9028e5fde3dcb 100644 --- a/sound/soc/tegra/Kconfig +++ b/sound/soc/tegra/Kconfig @@ -62,6 +62,16 @@ config SND_SOC_TEGRA30_I2S Tegra30 I2S interface.

From the signal flow perpsective, the DSPK can be viewed as a PDM transmitter that up-samples the input to the desired sampling rate by interpolation then converts the oversampled PCM input to the desired 1-bit output via Delta Sigma Modulation (DSM). This patch registers DSPK component with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes DSPK interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The DSPK devices can be enabled in the DT via "nvidia,tegra186-dspk" compatible binding. This driver can be used on Tegra194 chip as well.

KASAN reports a use-after-free error when unbinding drivers due to a confusing sequence between the ACPI core, the device core and the SoundWire device cleanups. Rather than fixing this sequence, follow the recommendation to have the same caller add and remove properties, add an explicit device_remove_properties() in the card .remove() callback. In future patches the use of device_add/remove_properties will be replaced by a direct handling of a swnode, but the sequence will remain the same.

The devlink is initialized at the same level, but after, as shown by a disassembly of the vmlinux: [ ... ] 374 ffff8000115f22c0 <__initcall_devlink_init4>: 375 ffff8000115f22c4 <__initcall_genl_init4>: [ ... ] The function devlink_init() calls genl_register_family() before the generic netlink subsystem is initialized. As the generic netlink initcall level is set since 2005, it seems that was not a problem, but now we have the thermal framework initialized at the core_initcall level which creates the generic netlink family and sends a notification which leads to a subtle memory corruption only detectable when the CONFIG_INIT_ON_ALLOC_DEFAULT_ON option is set with the earlycon at init time. The thermal framework needs to be initialized early in order to begin the mitigation as soon as possible. Moving it to postcore_initcall is acceptable. This patch changes the initialization level for the generic netlink family to the core_initcall and comes after the netlink protocol initialization. Signed-off-by: Daniel Lezcano Acked-by: David S.

Use of hrtimers addresses this and can be easily extended to support microsecond resolution in future when support for this arrives upstream.

In order to have mute control of max98357 from machine drivers, commit 128f825aeab7 ("ASoC: max98357a: move control of SD_MODE to DAPM") moves the control of SD_MODE from DAI ops to DAPM events. However, pop noise has been observed on rk3399-gru-kevin boards due to this commit. The commit 128f825aeab7 caused sequence of DAI clocks and SD_MODE changed on rk3399-gru-kevin boards. With the commit 128f825aeab7: - SD_MODE will be set to 1 before DAI clocks start. - SD_MODE will be set to 0 after DAI clocks stop. As a result, pop noise.

Each ADMA channel that sends/receives data to/from AHUB must intreface through an ADMAIF channel. ADMA channel sending data to AHUB pairs with an ADMAIF Tx channel and similarly ADMA channel receiving data from AHUB pairs with an ADMAIF Rx channel. Buffer size is configurable for each ADMAIF channel, but currently SW uses default values. This patch registers ADMAIF driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes ADMAIF interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow to build the driver. The ADMAIF device can be enabled in the DT via "nvidia,tegra210-admaif" compatible binding. Tegra PCM driver is updated to expose required PCM interfaces and snd_pcm_ops callbacks.

The generic HDA machine driver relied on the old semantics to disable i915 HDMI/DP audio codec at runtime.

This gap has been there from the start, commit 6bae5ea94989 ("ASoC: hdac_hda: add asoc extension for legacy HDA codec drivers"). Instead of duplicating the cleanup logic, use the common snd_hda_codec_cleanup_for_unbind() to free the resources. Remove existing code in hdac_hda to cleanup "codec.jackpoll_work" and call to snd_hdac_regmap_exit(), as these are already done in snd_hda_codec_cleanup_for_unbind(). The cleanup is done in ASoC component remove() callback and not in the HDAC bus hdev_detach(). This is done to ensure the codec specific cleanup routines are run before the parent card is freed.

If startup() returns an error, shutdown() is now called for the DAI. This causes a deadlock in hdac_hda which issues a call to snd_hda_codec_pcm_put() in case open fails. Upon error, soc_pcm_open() will call shutdown(), and pcm_put() ends up getting called twice. Result is a deadlock on pcm->open_mutex, as snd_device_free() gets called from within snd_pcm_open().

The HW parameters are changed based on the codec DAI of the stream. The earlier approach to get snd_soc_dpcm was using container_of() macro on snd_pcm_hw_params. The structures have been modified over time and snd_soc_dpcm does not have snd_pcm_hw_params as a reference but as a copy. This causes the current driver to crash when used. This patch changes the way snd_soc_dpcm is extracted. snd_soc_pcm_runtime holds 2 dpcm instances (one for playback and one for capture). 2 codecs on the SSP are dmic (capture) and speakers (playback). Based on the stream direction, snd_soc_dpcm is extracted from snd_soc_pcm_runtime. Tested for all use cases of the driver.

This is necessary because those parameters are now validated to match the capabilities of the DAIs. [1] The disadvantage of introducing the call to q6afe_is_rx_port() is that it makes the qcom_snd_parse_of() helper dependent on the QDSP6 driver. When the ADSP is bypassed (e.g. in apq8016-sbc) QDSP6 is not used. There is a generic solution for this now: The correct direction for the links is already defined by the DAI capabilities (e.g. rx ports only support playback). Commit 25612477d20b ("ASoC: soc-dai: set dai_link dpcm_ flags with a helper") introduced the snd_soc_dai_link_set_capabilities() function that we can use to set dpcm_playback/dpcm_capture according to the capabilities of the DAIs. Use that for both FE/BE DAI links to avoid the dependency on the QDSP6 driver.

Given the similarity of the two functions it is useful to combine these two. To allow using qcom_snd_parse_of() in apq8016_sbc we need to support parsing links without DPCM as well. This is pretty simple: A DPCM link in the device tree is defined using: - DPCM frontend: "cpu" - DPCM backend: "cpu", "platform" and "codec" ... while a link without DPCM has "cpu" and "codec" (but no "platform"). Add a few more if conditions to handle links without DPCM correctly.

If card doesn't provide set_bias_level callback, the snd_soc_dapm_set_bias_level() is equivalent to NOP for card device. As a result, dapm_pre_sequence_async() doesn't change the bias_level of card device correctly. Thus, pm_runtime_get_sync() would be called in dapm_pre_sequence_async() without symmetric pm_runtime_put() in dapm_post_sequence_async(). Don't call pm_runtime_* on card device.

The standards-compliant parts, such as querying the crypto capabilities and enabling crypto for individual UFS requests, are already handled by ufshcd-crypto.c, which itself is wired into the blk-crypto framework. However, ICE requires vendor-specific init, enable, and resume logic, and it requires that keys be programmed and evicted by vendor-specific SMC calls. Make the ufs-qcom driver handle these details. I tested this on Dragonboard 845c, which is a publicly available development board that uses the Snapdragon 845 SoC and runs the upstream Linux kernel. This is the same SoC used in the Pixel 3 and Pixel 3 XL phones. This testing included (among other things) verifying that the expected ciphertext was produced, both manually using ext4 encryption and automatically using a block layer self-test I've written. I've also tested that this driver works nearly as-is on the Snapdragon 765 and Snapdragon 865 SoCs. And others have tested it on Snapdragon 850, Snapdragon 855, and Snapdragon 865 (see the Tested-by tags). This is based very loosely on the vendor-provided driver in the kernel source code for the Pixel 3, but I've greatly simplified it. Also, for now I've only included support for major version 3 of ICE, since that's all I have the hardware to test with the mainline kernel. Plus it appears that version 3 is easier to use than older versions of ICE. For now, only allow using AES-256-XTS. The hardware also declares support for AES-128-XTS, AES-{128,256}-ECB, and AES-{128,256}-CBC (BitLocker variant). But none of these others are really useful, and they'd need to be individually tested to be sure they worked properly. This commit also changes the name of the loadable module from "ufs-qcom" to "ufs_qcom", as this is necessary to compile it from multiple source files (unless we were to rename ufs-qcom.c).

However, the commit's implementation was awkward; it forced the SCSI system-resume handler to choose whether to call blk_post_runtime_resume() or blk_set_runtime_active(), depending on whether or not the SCSI device had previously been runtime suspended. This patch simplifies the situation considerably by adding the missing function call directly into blk_set_runtime_active() (under the condition that the queue is not already in the RPM_ACTIVE state). This allows the SCSI routine to revert back to its original form. Furthermore, making this change reveals that blk_post_runtime_resume() (in its success pathway) does exactly the same thing as blk_set_runtime_active(). The duplicate code is easily removed by making one routine call the other. No functional changes are intended.

Typically it's used from the interrupt handler to fetch the command associated with a value returned from hardware. Some drivers like fnic or qla4xxx, however, also use it also to traverse outstanding commands. With the current implementation scsi_host_find_tag() will return commands even if they are not started (i.e. passed to the driver). This will result in random errors with those drivers. With this patch scsi_host_find_tag() will only return 'started' commands (i.e. commands which have been passed to the drivers) thus avoiding the above issue. The other use cases will be unaffected as the interrupt handler naturally will only ever return 'started' requests.

Klimov" Date: Tue, 21 Jul 2020 20:35:45 +0200 Subject: [PATCH 1428/1675] staging: comedi: addi: Replace HTTP links with HTTPS ones Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Different from its predecessor MSM8916, where 'calib_sel' bits sit in separate qfprom word, MSM8939 has 'cailb' and 'calib_sel' bits mixed and spread on discrete offsets. That's why all qfprom bits are read as one go and later mapped to calibration data for MSM8939.

It is a remnant from the times when a group could only have an inode mark associated with an event. We now pass an iter_info array to the callback, with all marks associated with an event. Most backends ignore this argument, with two exceptions: 1. dnotify uses it for sanity check that event is on directory 2. fanotify uses it to report fid of directory on directory entry modification events Remove the 'inode' argument and add a 'dir' argument. The callback function signature is deliberately changed, because the meaning of the argument has changed and the arguments have been documented. The 'dir' argument is set to when 'file_name' is specified and it is referring to the directory that the 'file_name' entry belongs to.

It is used by fanotify to get a single handle_event callback when an event has a match to either of inode/sb/mount marks of the group. The nature of fsnotify events is that they are associated with at most one sb at most one mount and at most one inode. When a parent and child are both watching, two events are sent to backend, one associated to parent inode and one associated to the child inode. This results in duplicate events in fanotify, which usually get merged before user reads them, but this is sub-optimal. It would be better if the same event is sent to backend with an object type iterator that has both the child inode and its parent, and let the backend decide if the event should be reported once (fanotify) or twice (inotify).

Encapsulate the name_len member of fanotify_name_event in a new struct fanotify_info, which describes the parceling of the variable size buffer of an fanotify_name_event. The dir_fh member of fanotify_name_event is renamed to _dir_fh and is not accessed directly, but via the fanotify_info_dir_fh() accessor. Although the dir_fh len information is already available in struct fanotify_fh, we store it also in dif_fh_totlen member of fanotify_info, including the size of fanotify_fh header, so we know the offset of the name in the buffer without looking inside the dir_fh. We also add a file_fh_totlen member to allow packing another file handle in the variable size buffer after the dir_fh and before the name. We are going to use that space to store the child fid.

The parent inode is assigned to the standard "inode" iterator type and the child inode is assigned to the special "child" iterator type. In that case, the bit FS_EVENT_ON_CHILD will be set in the event mask, the dir argument to handle_event will be the parent inode, the file_name argument to handle_event is non NULL and refers to the name of the child and the child inode can be accessed with fsnotify_data_inode(). This will allow fanotify to make decisions based on child or parent's ignored mask. For example, when a parent is interested in a specific event on its children, but a specific child wishes to ignore this event, the event will not be reported. This is not what happens with current code, but according to man page, it is the expected behavior.

The FS_EVENT_ON_CHILD flag can be set on sb/mount/non-dir marks to specify interest in parent/name info for events on non-directory inodes. Events on "orphan" children (disconnected dentries) are sent without parent/name info. Events on directories are sent with parent/name info only if the parent directory is watching. After this change, even groups that do not subscribe to events on children could get an event with mark iterator type TYPE_CHILD and without mark iterator type TYPE_INODE if fanotify has marks on the same objects. dnotify and inotify event handlers can already cope with that situation. audit does not subscribe to events that are possible on child, so won't get to this situation. nfsd does not access the marks iterator from its event handler at the moment, so it is not affected. This is a bit too fragile, so we should prepare all groups to cope with mark type TYPE_CHILD preferably using a generic helper.

When adding a filesystem or mount mark or mark on a non-dir inode, we want to report events that are "possible on child" (e.g. open/close) also with fid of the parent, as if the victim inode's parent is interested in events "on child". Some events, currently only FAN_MOVE_SELF, should be reported to a sb/mount/non-dir mark with parent fid even though they are not reported to a watching parent. To get the desired behavior we set the flag FAN_EVENT_ON_CHILD on all the sb/mount/non-dir mark masks in a group with FAN_REPORT_DIR_FID.

Most backends do not care about this complex functionality, so we can hide this complexity from them. Introduce a method handle_inode_event() that serves those backends and passes a single inode mark and less arguments. This change converts all backends except fanotify and inotify to use the simplified handle_inode_event() method. In pricipal, inotify could have also used the new method, but that would require passing more arguments on the simple helper (data, data_type, cookie), so we leave it with the handle_event() method.

The status of the remaining issue mentioned in TODO is not clear, we asked the speakup user mailing list for reproducer cases, but didn't get a really specific scenario. One serious bug was fixed by 9d32c0cde4e2 ("staging/speakup: fix get_word non-space look-ahead"), which does not seem to really be related to the bug mentioned in TODO. Possibly the bug mentioned in TODO has been fixed long ago and people have been thinking that it was not because they can not distinguish the symptoms mentioned in TODO from the symptoms of the bug fixed by 9d32c0cde4e2.

Therefore tcmu_set_next_deadline() finds no new deadline and stops the timer, which it shouldn't. Since commands that time out are removed from inflight_queue or qfull_queue, we don't need the check with time_after() in tcmu_set_next_deadline() but can use the deadline from the first cmd in the queue. Additionally, replace the remaining time_after() calls in tcmu_check_expired_xxxxx_cmd() with time_after_eq(), because it is not useful to set the timeout to deadline but then check for jiffies being greater than deadline. Simplify the end of tcmu_handle_completions() and change the check for no more pending commands from mb->cmd_tail == mb->cmd_head to idr_is_empty(&udev->commands) because the old check doesn't work correctly if paddings or in the future TMRs are in the ring. Finally tcmu_set_next_deadline() was shifted in the source as preparation for later implementation of tmr_notify callback.

When the callback is called, tcmu checks the list of aborted commands it received as parameter: - aborted commands in the qfull_queue are removed from the queue and target_complete_command is called - from the cmd_ids of aborted commands currently uncompleted in cmd ring it creates a list of aborted cmd_ids. Finally a TMR notification is written to cmd ring containing TMR type and cmd_id list. If there is no space in ring, the TMR notification is queued on a TMR specific queue. The TMR specific queue 'tmr_queue' can be seen as a extension of the cmd ring. At the end of each iexecution of tcmu_complete_commands() we check whether tmr_queue contains TMRs and try to move them onto the ring. If tmr_queue is not empty after that, we don't call run_qfull_queue() because commands must not overtake TMRs. This way we guarantee that cmd_ids in TMR notification received by userspace either match an active, not yet completed command or are no longer valid due to userspace having complete some cmd_ids meanwhile. New commands that were assigned to an aborted cmd_id will always appear on the cmd ring _after_ the TMR.

This is unrealistic as even SSDs take some time after power-on before accepting media access commands. Add the tur_ms_to_ready parameter whose unit is milliseconds (default 0) and is the period before which a TUR (or any media access command) will set the CHECK CONDITION status with a sense key of NOT READY and an additional sense of "Logical unit is in process of becoming ready". The period starts when each scsi_debug device is created. This patch was prompted by T10 proposal 20-061r2 which was accepted on 2020716. It adds that a TUR in the situation described in the previous paragraph may set the INFO field (or descriptor) in the sense data to the estimated number in milliseconds before a subsequent TUR will yield a GOOD status. This patch follows that advice. Link: https://lore.kernel.org/r/20200724155531.668144-1-dgilbert@interlog.com Reported-by: kernel test robot Signed-off-by: Douglas Gilbert Signed-off-by: Martin K.

They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

Currently you can't enable the Gey Bus Audio Codec because there is no entry for it in the Kconfig file. Originally the config name was going to be AUDIO_MSM8994 but that's not correct because other types of hardware are supported now. I have chosen the name AUDIO_APB_CODEC instead. Also I had to update the dependencies for GREYBUS_AUDIO to make the compile work.

In Baikal-T1 SoC this may happen due to the reference clock being shared between two UART ports, on the Allwinner SoC the reference clock is derived from the CPU clock, so any CPU frequency change should get to be known/reflected by/in the UART controller as well. But it's not enough to just update the uart_port->uartclk field of the corresponding UART port, the 8250 controller reference clock divisor should be altered so to preserve current baud rate setting. All of these things is done in a coherent way by calling the serial8250_update_uartclk() method provided in this patch. Though note that it isn't supposed to be called from within the UART port callbacks because the locks using to the protect the UART port data are already taken in there.

In this case if that device changes the clock rate while serial console is using it the DW 8250 UART port might not only end up with an invalid uartclk value saved, but may also experience a distorted output data since baud-clock could have been changed. In order to fix this lets at least try to adjust the 8250 port setting like UART clock rate in case if the reference clock rate change is discovered. The driver will call the new method to update 8250 UART port clock rate settings. It's done by means of the clock event notifier registered at the port startup and unregistered in the shutdown callback method. Note 1. In order to avoid deadlocks we had to execute the UART port update method in a dedicated deferred work. This is due to (in my opinion redundant) the clock update implemented in the dw8250_set_termios() method. Note 2. Before the ref clock is manually changed by the custom set_termios() function we swap the port uartclk value with new rate adjusted to be suitable for the requested baud. It is necessary in order to effectively disable a functionality of the ref clock events handler for the current UART port, since uartclk update will be done a bit further in the generic serial8250_do_set_termios() function.

This results in active operations being left running after rdma_destroy_id() completes, and the use-after-free bugs from KASAN. Consolidate this entire pattern into destroy_id_handler_unlock() and manage the locking correctly. The state should be set to RDMA_CM_DESTROYING under the handler_lock to atomically ensure no futher handlers are called.

However ashmem does not support writing into backing shmem with a write syscall. The only way to change its content is to mmap it and operate on mapped memory. Therefore the race that lockdep is warning about is not valid. Resolve this by introducing a separate lockdep class for the backing shmem inodes.

This is true for TDM configurations but existing configurations use an amplifier and a capture device on the same dailink, and the tests would prevent the card from probing. This patch modifies the snd_soc_dai_link_set_capabilities() helper so that the dpcm_playback (resp. dpcm_capture) dailink capabilities are set if at least one dai supports playback (resp. capture). Likewise the checks are modified so that an error is reported only when dpcm_playback (resp. dpcm_capture) is set but none of the CPU DAIs support playback (resp. capture).

However, extended inode is now 64-byte form, which can across page boundary in principle if the location is specified on purpose, although it's hard to be generated by mkfs due to the allocation policy and rarely used by Android use case now mainly for > 4GiB files. For now, only two fields `i_ctime_nsec` and `i_nlink' couldn't be read from disk properly and cause out-of-bound memory read with random value. Let's fix now.

USB device (17aa:104d) provides functionality for Internal Speaker and Front Headset. It's UAC v2, so it supports insertion control (jack detection). However, when trying to get the connector status of the speaker, an error occurs: [ 5.787405] usb 3-1: cannot get connectors status: req = 0x81, wValue = 0x200, wIndex = 0x1000, type = 0 Since the insertion control works perfectly for the headset, the error for speaker is probably casued by connecting internally. So let's relax the error for a bit if it's a speaker, and always reports it's connected. USB device (17aa:1046) is for rear Line-in, Line-out and Microphone. The insertion control works for all three jacks. However, there's an Function Unit that doesn't work: [ 5.905415] usb 3-6: cannot get ctl value: req = 0x83, wValue = 0xc00, wIndex = 0x1300, type = 4 [ 5.905418] usb 3-6: 19:0: cannot get min/max values for control 12 (id 19) So turn off the FU to avoid the error. Also, add specific card name for both devices, so userspace can easily indentify both cards.

Basically OSS sequencer API is an obsoleted interface and was designed without much consideration of the concurrency. There are very few applications with it, and the concurrent performance isn't asked, hence this "big hammer" approach should be good enough.

HW will keep issuing new data fetch request when buffers are not full and current BDL is not done. When SW disable DMA RUN bit for a stream, HW can't cancel the already issued data fetch request and hence it can't stop DMA. HW has to wait for all issued data fetch request get data returned before it stops DMA. This HW behavior is not in sync with HDA spec which says DMA RUN bit should be cleared within 1 audio frame. For Tegra, DMA RUN bit was active for more than one audio frame, due to this the timeout in snd_hdac_stream_sync function is not helping. When Stream reset set and clear happens during DMA RUN bit active state it results in Memory Decode error. Unfortunately, there is no way to detect when these data accesses have completed, but testing has shown that a 100us delay between Stream reset set and clear operation for Tegra avoids the memory decode error. Therefore, adding a 100us dma stop delay.

XFS has carried this ever since. In the initial linux ports it was necessary to get mmap and DIO to play "ok" together and not immediately corrupt data. This was the state of play until the linux kernel had infrastructure to track unwritten extents and synchronise page faults with allocations and unwritten extent conversions (->page_mkwrite infrastructure). IOws, the page cache invalidation on DIO read was necessary to prevent trivial data corruptions. This didn't solve all the problems, though. There were peformance problems if we didn't invalidate the entire page cache over the file on read - we couldn't easily determine if the cached pages were over the range of the IO, and invalidation required taking a serialising lock (i_mutex) on the inode. This serialising lock was an issue for XFS, as it was the only exclusive lock in the direct Io read path. Hence if there were any cached pages, we'd just invalidate the entire file in one go so that subsequent IOs didn't need to take the serialising lock. This was a problem that prevented ranged invalidation from being particularly useful for avoiding the remaining coherency issues. This was solved with the conversion of i_mutex to i_rwsem and the conversion of the XFS inode IO lock to use i_rwsem. Hence we could now just do ranged invalidation and the performance problem went away. However, page cache invalidation was still needed to serialise sub-page/sub-block zeroing via direct IO against buffered IO because bufferhead state attached to the cached page could get out of whack when direct IOs were issued. We've removed bufferheads from the XFS code, and we don't carry any extent state on the cached pages anymore, and so this problem has gone away, too. IOWs, it would appear that we don't have any good reason to be invalidating the page cache on DIO reads anymore. Hence remove the invalidation on read because it is unnecessary overhead, not needed to maintain coherency between mmap/buffered access and direct IO anymore, and prevents anyone from using direct IO reads from intentionally invalidating the page cache of a file.

At first we only close the connection related to the communication failure. If we get a new connection for an already existing connection we close the existing connection and take the new one. This patch improves significantly the stability of tcp connections while running "tcpkill -9 -i $IFACE port 21064" while generating a lot of dlm messages e.g. on a gfs2 mount with many files. My test setup shows that a deadlock is "more" unlikely. Before this patch I wasn't able to get not a deadlock after 5 seconds. After this patch my observation is that it's more likely to survive after 5 seconds and more, but still a deadlock occurs after certain time. My guess is that there are still "segments" inside the tcp writequeue or retransmit queue which get dropped when receiving a tcp reset [1]. Hard to reproduce because the right message need to be inside these queues, which might even be in the 5 first seconds with this patch.

This patch will introduce a graceful shutdown for tcp connections. The shutdown is implemented synchronized as dlm_lowcomms_stop() is called to end all dlm communication. After shutdown is done, a lot of flush and closing functionality will be called. However I don't see a problem with that. The waitqueue for synchronize the shutdown has a timeout of 10 seconds, if timeout a force close will be exectued.
