3662f82f - perf test: Speed up some tests using perf list

Wed, 16 Oct 2024 06:56:54 +0000

perf test: Speed up some tests using perf listOn my system, perf list is very slow to print the whole events. I thinkthere's a performance issue in SDT and uprobes event listing. I noticedthis issue while running perf test on x86 but it takes long to checksome CoreSight event which should be skipped quickly.Anyway, some test uses perf list to check whether the required event isavailable before running the test. The perf list command can take anargument to specify event class or (glob) pattern. But glob pattern isonly to suppress output for unmatched ones after checking all events.In this case, specifying event class is better to reduce the number ofevents it checks and to avoid buggy subsystems entirely.No functional changes intended.Reviewed-by: James Clark Reviewed-by: Ian Rogers Cc: German Gomez Cc: Carsten Haitzler Cc: Leo Yan Link: https://lore.kernel.org/r/20241016065654.269994-1-namhyung@kernel.orgSigned-off-by: Namhyung Kim List of files: /linux-6.15/tools/perf/tests/shell/test_arm_spe_fork.sh

perf tools: Use "grep -E" instead of "egrep"The latest version of grep claims the egrep is now obsolete so the buildnow contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -Efix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATHSigned-off-by: Tiezhu Yang Acked-by: Ian Rogers Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lore.kernel.org/lkml/1668762999-9297-1-git-send-email-yangtiezhu@loongson.cnSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/shell/test_arm_spe_fork.sh

e011979e - perf test: Replace arm spe fork test workload with sqrtloop

perf test: Replace arm spe fork test workload with sqrtloopSo that it can get rid of requirement of a compiler. I've also removedkillall as it'll kill perf process now and run the test workload for 10sec instead.Signed-off-by: Namhyung Kim Tested-by: James Clark Tested-by: Leo Yan Cc: Adrian Hunter Cc: Athira Jajeev Cc: German Gomez Cc: Ian Rogers Cc: Ingo Molnar Cc: Jiri Olsa Cc: Peter Zijlstra Cc: Zhengjun Xing Link: https://lore.kernel.org/r/20221116233854.1596378-9-namhyung@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/tests/shell/test_arm_spe_fork.sh
