2021-05-21perf tests: Consolidate test__arch_unwind_sample declarationRob Herring
There's no reason for making the test__arch_unwind_sample declaration per arch. Currently that's done 2 different ways either with a declaration in arch-tests.h or with an arch define. Unify all this with an unconditional declaration in tests.h.

2021-03-06perf test: Support the ins_lat check in the X86 specific testKan Liang
The ins_lat of PERF_SAMPLE_WEIGHT_STRUCT stands for the instruction latency, which is only available for X86. Add a X86 specific test for the ins_lat and PERF_SAMPLE_WEIGHT_STRUCT type. The test__x86_sample_parsing() uses the same way as the test__sample_parsing() to verify a sample type. Since the ins_lat and PERF_SAMPLE_WEIGHT_STRUCT are the only X86 specific sample type for now, the test__x86_sample_parsing() only verify the PERF_SAMPLE_WEIGHT_STRUCT type. Other sample types are still verified in the generic test. $ perf test 77 -v 77: x86 Sample parsing : --- start --- test child forked, pid 102370 test child finished with 0 ---- end ---- x86 Sample parsing: Ok Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Cc: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Sumanth Korikkar <sumanthk@linux.ibm.com> Cc: Sven Schnelle <svens@linux.ibm.com> Cc: Thomas Richter <tmricht@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: http://lore.kernel.org/lkml/1614787285-104151-2-git-send-email-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2020-11-16perf test: Avoid an msan warning in a copied stack.Ian Rogers
This fix is for a failure that occurred in the DWARF unwind perf test. Stack unwinders may probe memory when looking for frames. Memory sanitizer will poison and track uninitialized memory on the stack, and on the heap if the value is copied to the heap. This can lead to false memory sanitizer failures for the use of an uninitialized value. Avoid this problem by removing the poison on the copied stack. The full msan failure with track origins looks like: ==2168==WARNING: MemorySanitizer: use-of-uninitialized-value #0 0x559ceb10755b in handle_cfi elfutils/libdwfl/frame_unwind.c:648:8 #1

2020-11-04perf tests tsc: Make tsc testing as a common testingLeo Yan
x86 arch provides the testing for conversion between tsc and perf time, the testing is located in x86 arch folder. Move this testing out from x86 arch folder and place it into the common testing folder, so allows to execute tsc testing on other architectures (e.g. Arm64). This patch removes the inclusion of "arch-tests.h" from the testing code, this can avoid building failure if any arch has no this header file. Committer testing: $ perf test -v tsc Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc 70: Convert perf time to TSC : --- start --- test child forked, pid 4032834 mmap size 528384B 1st event perf time 165409788843605 tsc 336578703793868 rdtsc time 165409788854986 tsc 336578703837038 2nd event perf time 165409788855487 tsc 336578703838935 test child finished with 0 ---- end ---- Convert perf time to TSC: Ok $ Signed-off-by: Leo Yan <leo.yan@linaro.org> Acked-by: Jiri Olsa <jolsa@redhat.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Link: https://lore.kernel.org/r/20201019100236.23675-2-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2019-11-26perf maps: Merge 'struct maps' with 'struct map_groups'Arnaldo Carvalho de Melo
And pick the shortest name: 'struct maps'. The split existed because we used to have two groups of maps, one for functions and one for variables, but that only complicated things, sometimes we needed to figure out what was at some address and then had to first try it on the functions group and if that failed, fall back to the variables one. That split is long gone, so for quite a while we had only one struct maps per struct map_groups, simplify things by combining those structs. First patch is the minimum needed to merge both, follow up patches will rename 'thread->mg' to 'thread->maps', etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-hom6639ro7020o708trhxh59@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2019-08-31perf intel-pt: Use shared x86 insn decoderJosh Poimboeuf
Now that there's a common version of the decoder for all tools, use it instead of the local copy. Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync.

2019-07-29libperf: Add perf_cpu_map__new()/perf_cpu_map__read() functionsJiri Olsa
Moving the following functions from tools/perf: cpu_map__new() cpu_map__read() to libperf with the following names: perf_cpu_map__new() perf_cpu_map__read() Committer notes: Fixed up this one: tools/perf/arch/arm/util/cs-etm.c Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexey Budankov <alexey.budankov@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20190721112506.12306-44-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2019-07-29libperf: Move perf_event_attr field from perf's evsel to libperf's perf_evselJiri Olsa
Move the perf_event_attr struct fron 'struct evsel' to 'struct perf_evsel'. Committer notes: Fixed up these: tools/perf/arch/arm/util/auxtrace.c tools/perf/arch/arm/util/cs-etm.c tools/perf/arch/arm64/util/arm-spe.c tools/perf/arch/s390/util/auxtrace.c tools/perf/util/cs-etm.c Also cc1: warnings being treated as errors tests/sample-parsing.c: In function 'do_test': tests/sample-parsing.c:162: error: missing initializer tests/sample-parsing.c:162: error: (near initialization for 'evsel.core.cpus') struct evsel evsel = { .needs_swap = false, - .core.attr = { - .sample_type = sample_type, - .read_format = read_format, + .core = { + . attr = { + .sample_type = sample_type, + .read_format = read_format, + }, [perfbuilder@a70e4eeb5549 /]$ gcc --version |& head -1 gcc (GCC) 4.4.7 Also we don't need to include perf_event.h in tools/perf/lib/include/perf/evsel.h, forward declaring 'struct perf_event_attr' is enough. And this even fixes the build in some systems where things are used somewhere down the include path from perf_event.h without defining __always_inline.
