3656e566 - perf test: Add landlock workload

Mon, 24 Jun 2024 18:13:42 +0000

perf test: Add landlock workloadWe'll use it to add a regression test for the BTF augmentation of enumarguments for tracepoints in 'perf trace': root@x1:~# perf trace -e landlock_add_rule perf test -w landlock 0.000 ( 0.009 ms): perf/747160 landlock_add_rule(ruleset_fd: 11, rule_type: LANDLOCK_RULE_PATH_BENEATH, rule_attr: 0x7ffd8e258594, flags: 45) = -1 EINVAL (Invalid argument) 0.011 ( 0.002 ms): perf/747160 landlock_add_rule(ruleset_fd: 11, rule_type: LANDLOCK_RULE_NET_PORT, rule_attr: 0x7ffd8e2585a0, flags: 45) = -1 EINVAL (Invalid argument) root@x1:~#Committer notes:It was agreed on the discussion (see Link below) to shorten then name ofthe workload from 'landlock_add_rule' to 'landlock', and I moved it to aseparate patch.Also, to address a build failure from Namhyung, I stopped loadinglinux/landlock.h and instead added the used defines, enums and types tomake this build in older systems. All we want is to emit the syscall andintercept it.Suggested-by: Arnaldo Carvalho de Melo Signed-off-by: Howard Chu Tested-by: Arnaldo Carvalho de Melo Cc: Adrian Hunter Cc: Ian Rogers Cc: Jiri Olsa Cc: Kan Liang Cc: Namhyung Kim Link: https://lore.kernel.org/lkml/CAH0uvohaypdTV6Z7O5QSK+va_qnhZ6BP6oSJ89s1c1E0CjgxDA@mail.gmail.comLink: https://lore.kernel.org/r/20240624181345.124764-1-howardchu95@gmail.comLink: https://lore.kernel.org/r/20240624181345.124764-6-howardchu95@gmail.comSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build

3dfc01fe - perf test: Add 'datasym' test workload

Wed, 16 Nov 2022 23:38:53 +0000

perf test: Add 'datasym' test workloadThe datasym workload is to check if perf mem command gets the dataaddresses precisely. This is needed for data symbol test. $ perf test -w datasymI had to keep the buf1 in the data section, otherwise it could endup in the BSS and was mmaped as a separate //anon region, then itwas not symbolized at all. It needs to be fixed separately.Committer notes:Add a -U _FORTIFY_SOURCE to the datasym CFLAGS, as the main perf flagsset it and it requires building with optimization, and this new test hasa -O0.Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Leo Yan Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-12-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build

a104f0ea - perf test: Add 'brstack' test workload

Wed, 16 Nov 2022 23:38:51 +0000

perf test: Add 'brstack' test workloadThe brstack is to run different kinds of branches repeatedly. This isnecessary for brstack test case to verify if it has correct branch info. $ perf test -w brstackI renamed the internal functions to have brstack_ prefix as it's toogeneric name.Add a -U_FORTIFY_SOURCE to the brstack CFLAGS, as the main perf flagsset it and it requires building with optimization, and this new test hasa -O0.Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Leo Yan Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-10-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build

39281709 - perf test: Add 'sqrtloop' test workload

Wed, 16 Nov 2022 23:38:49 +0000

perf test: Add 'sqrtloop' test workloadThe sqrtloop creates a child process to run an infinite loop callingsqrt() with rand(). This is needed for ARM SPE fork test. $ perf test -w sqrtloopIt can take an optional argument to specify how long it will run inseconds (default: 1).Committer notes:Explicitely ignored the sqrt() return to fix the build on systems wherethe compiler complains it isn't being used.And added a sqrtloop specific CFLAGS to disable optimizations to makethis a bit more robust wrt dead code elimination.Doing that a -U_FORTIFY_SOURCE needs to be added, as -O0 is incompatiblewith it.Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Leo Yan Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-8-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build

perf test: Add 'leafloop' test workloadThe leafloop workload is to run an infinite loop in the test_leaffunction. This is needed for the ARM fp callgraph test to verify if itgets the correct callchains. $ perf test -w leafloopCommitter notes:Add a: -U_FORTIFY_SOURCEto the leafloop CFLAGS as the main perf flags set it and it requiresbuilding with optimization, and this new test has a -O0.Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Leo Yan Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-6-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build

69b35292 - perf test: Add 'thloop' test workload

Wed, 16 Nov 2022 23:38:45 +0000

perf test: Add 'thloop' test workloadThe thloop is similar to noploop but runs in two threads. This isneeded to verify perf record --per-thread to handle multi-threadedprograms properly. $ perf test -w thloopIt also takes an optional argument to specify runtime in seconds(default: 1).Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Leo Yan Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-4-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build

f215054d - perf test: Add -w/--workload option

Wed, 16 Nov 2022 23:38:43 +0000

perf test: Add -w/--workload optionThe -w/--workload option is to run a simple workload used by testing.This adds a basic framework to run the workloads and 'noploop' workloadas an example. $ perf test -w noploopThe noploop does a loop doing nothing (NOP) for a second by default.It can have an optional argument to specify the time in seconds.Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Leo Yan Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-2-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/workloads/Build
