perf test: Make tests its own library

2024-06-26T18:07:11Z

Make the tests code its own library. This is done to avoid compiling code twice, once for the perf tool and once for the perf python module.

Pull perf tools updates from Namhyung Kim: "Internal cleanup: - Refactor PMU data management to handle hybrid systems in a generic way. Do more work in the lexer so that legacy event types parse more easily. A side-effect of this is that if a PMU is specified, scanning sysfs is avoided improving start-up time. - Fix hybrid metrics, for example, the TopdownL1 works for both performance and efficiency cores on Intel machines. To support this, sort and regroup events after parsing. - Add reference count checking for the 'thread' data structure. - Lots of fixes for memory leaks in various places thanks to the ASAN and Ian's refcount checker. - Reduce the binary size by replacing static variables with local or dynamically allocated memory. - Introduce shared_mutex for annotate data to reduce memory footprint. - Make filesystem access library functions more thread safe. Test: - Organize cpu_map tests into a single suite. - Add metric value validation test to check if the values are within correct value ranges. - Add perf stat stdio output test to check if event and metric names match. - Add perf data converter JSON output test. - Fix a lot of issues reported by shellcheck(1). This is a preparation to enable shellcheck by default. - Make the large x86 new instructions test optional at build time using EXTRA_TESTS=1. - Add a test for libpfm4 events. perf script: - Add 'dsoff' outpuf field to display offset from the DSO. $ perf script -F comm,pid,event,ip,dsoff ls 2695501 cycles: 152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5) ls 2695501 cycles: ffffffff99045b3e ([kernel.kallsyms]) ls 2695501 cycles: ffffffff9968e107 ([kernel.kallsyms]) ls 2695501 cycles: ffffffffc1f54afb ([kernel.kallsyms]) ls 2695501 cycles: ffffffff9968382f ([kernel.kallsyms]) ls 2695501 cycles: ffffffff99e00094 ([kernel.kallsyms]) ls 2695501 cycles: 152cc718a8d0 (/usr/lib/x86_64-linux-gnu/libselinux.so.1+0x68d0) ls 2695501 cycles: ffffffff992a6db0 ([kernel.kallsyms]) - Adjust width for large PID/TID values. perf report: - Robustify reading addr2line output for srcline by checking sentinel output before the actual data and by using timeout of 1 second. - Allow config terms (like 'name=ABC') with breakpoint events. $ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1 perf annotate: - Handle x86 instruction suffix like 'l' in 'movl' generally. - Parse instruction operands properly even with a whitespace.

perf tests: Make x86 new instructions test optional at build time

2023-06-14T02:40:32Z

The "x86 instruction decoder - new instructions" test takes up space but is only really useful to developers. Make it optional at build time. Add variable EXTRA_TESTS which must be defined in order to build perf with the test.

perf test: Support the ins_lat check in the X86 specific test

2021-03-06T19:54:32Z

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 Cc: Athira Jajeev Cc: Heiko Carstens Cc: Sumanth Korikkar Cc: Sven Schnelle Cc: Thomas Richter Cc: Vasily Gorbik Link: http://lore.kernel.org/lkml/1614787285-104151-2-git-send-email-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf tests tsc: Make tsc testing as a common testing

2020-11-04T12:42:40Z

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 Acked-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Link: https://lore.kernel.org/r/20201019100236.23675-2-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo
