perf tests test_arm_spe: Address shellcheck warnings about signal name case

2023-06-14T02:40:33+00:00

Running shellcheck -S on test_arm_spe.sh throws below warnings: #shellcheck -S warning tests/shell/test_arm_spe.sh In tests/shell/test_arm_spe.sh line 30: trap cleanup_files exit term int ^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined. ^--^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined. ^-^ SC3049 (warning): In POSIX sh, using lower/mixed case for signal names is undefined. Fixed this issue by using uppercase for "EXIT", "TERM" and "INIT" signals to avoid using lower/mixed case for signal names as input.

perf tools: Use "grep -E" instead of "egrep"

2022-12-14T18:28:19+00:00

The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix 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:$PATH Signed-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.cn Signed-off-by: Arnaldo Carvalho de Melo

perf test: Add ARM SPE system wide test

2022-08-01T17:46:30+00:00

In the past it had a problem not setting the pid/tid on the sample correctly when system-wide mode is used. Although it's fixed now it'd be nice if we have a test case for it.
