That is because the head and tail are updated by +software, but in the auxtrace case the data is written by hardware. +So the head and tail do not get updated as data is written. + +In the Intel PT case, the head and tail are updated only when the trace +is disabled by software, for example: + - full-trace, system wide : when buffer passes watermark + - full-trace, not system-wide : when buffer passes watermark or + context switches + - snapshot mode : as above but also when a snapshot is made + - sample mode : as above but also when a sample is made + +That means finished-round ordering doesn't work. An auxtrace buffer +can turn up that has data that extends back in time, possibly to the +very beginning of tracing. + +For a perf.data file, that problem is solved by going through the trace +and queuing up the auxtrace buffers in advance. + +For pipe mode, the order of events and timestamps can presumably +be messed up. + + +EXAMPLE +------- + +Examples can be found on perf wiki page "Perf tools support for Intel® Processor Trace": + +https://perf.wiki.kernel.org/index.php/Perf_tools_support_for_Intel%C2%AE_Processor_Trace + SEE ALSO -------- diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index 35e1f2a52435ee2afc386d8a9903d36f0693366b..2c30a2b577d3eeb0723f1388679107f0b3a04313 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -296,6 +296,7 @@ FEATURE_CHECK_LDFLAGS-libpython := $(PYTHON_EMBED_LDOPTS) FEATURE_CHECK_LDFLAGS-libaio = -lrt FEATURE_CHECK_LDFLAGS-disassembler-four-args = -lbfd -lopcodes -ldl +FEATURE_CHECK_LDFLAGS-disassembler-init-styled = -lbfd -lopcodes -ldl CORE_CFLAGS += -fno-omit-frame-pointer CORE_CFLAGS += -ggdb3 @@ -872,13 +873,16 @@ ifndef NO_LIBBFD ifeq ($(feature-libbfd-liberty), 1) EXTLIBS += -lbfd -lopcodes -liberty FEATURE_CHECK_LDFLAGS-disassembler-four-args += -liberty -ldl + FEATURE_CHECK_LDFLAGS-disassembler-init-styled += -liberty -ldl else ifeq ($(feature-libbfd-liberty-z), 1) EXTLIBS += -lbfd -lopcodes -liberty -lz FEATURE_CHECK_LDFLAGS-disassembler-four-args += -liberty -lz -ldl + FEATURE_CHECK_LDFLAGS-disassembler-init-styled += -liberty -lz -ldl endif endif $(call feature_check,disassembler-four-args) + $(call feature_check,disassembler-init-styled) endif ifeq ($(feature-libbfd-buildid), 1) @@ -992,6 +996,10 @@ ifeq ($(feature-disassembler-four-args), 1) CFLAGS += -DDISASM_FOUR_ARGS_SIGNATURE endif +ifeq ($(feature-disassembler-init-styled), 1) + CFLAGS += -DDISASM_INIT_STYLED +endif + ifeq (${IS_64_BIT}, 1) ifndef NO_PERF_READ_VDSO32 $(call feature_check,compile-32) diff --git a/tools/perf/arch/x86/tests/intel-pt-pkt-decoder-test.c b/tools/perf/arch/x86/tests/intel-pt-pkt-decoder-test.c index c933e3dcd0a82ec61bf777d0541d225376d2110b..9589314d60b724c28bc7210caf7b07fad5e4b51c 100644 --- a/tools/perf/arch/x86/tests/intel-pt-pkt-decoder-test.c +++ b/tools/perf/arch/x86/tests/intel-pt-pkt-decoder-test.c @@ -166,6 +166,14 @@ struct test_data { {2, {0x02, 0xb3}, INTEL_PT_BLK_4_CTX, {INTEL_PT_BEP_IP, 0, 0}, 0, 0 }, {2, {0x02, 0x33}, INTEL_PT_BLK_8_CTX, {INTEL_PT_BEP, 0, 0}, 0, 0 }, {2, {0x02, 0xb3}, INTEL_PT_BLK_8_CTX, {INTEL_PT_BEP_IP, 0, 0}, 0, 0 }, + /* Control Flow Event Packet */ + {4, {0x02, 0x13, 0x01, 0x03}, 0, {INTEL_PT_CFE, 1, 3}, 0, 0 }, + {4, {0x02, 0x13, 0x81, 0x03}, 0, {INTEL_PT_CFE_IP, 1, 3}, 0, 0 }, + {4, {0x02, 0x13, 0x1f, 0x00}, 0, {INTEL_PT_CFE, 0x1f, 0}, 0, 0 }, + {4, {0x02, 0x13, 0x9f, 0xff}, 0, {INTEL_PT_CFE_IP, 0x1f, 0xff}, 0, 0 }, + /* */ + {11, {0x02, 0x53, 0x09, 1, 2, 3, 4, 5, 6, 7}, 0, {INTEL_PT_EVD, 0x09, 0x7060504030201}, 0, 0 }, + {11, {0x02, 0x53, 0x3f, 2, 3, 4, 5, 6, 7, 8}, 0, {INTEL_PT_EVD, 0x3f, 0x8070605040302}, 0, 0 }, /* Terminator */ {0, {0}, 0, {0, 0, 0}, 0, 0 }, };
