Hello,
This patchset improves the perf record tests to check more cases so that it can find problems early. The motivation was a failure per-thread mmap with multi-threaded targets which Adrian is working on the fix.
Changes in v2) * fix shellcheck issues * drop unsupported --per-thread and --threads combination * do not use initial delay (-D option); instead it runs the target and wait for it separately using the recent waiting.sh library * add Adrian's Reviewed-by tags
I added a custom test program and more combinations like system-wide and command line workload (in per-process mode) testing with multi-threaded recording mode.
Currently it succeeds every tests when running as root!
$ sudo ./perf test -v 91 91: perf record tests : --- start --- test child forked, pid 108975 Build a test program Basic --per-thread mode test Basic --per-thread mode test [Success] Register capture test Register capture test [Success] Basic --system-wide mode test Basic --system-wide mode test [Success] Basic target workload test Basic target workload test [Success] test child finished with 0 ---- end ---- perf record tests: Ok
You can find it in 'perf/record-test-v2' branch in
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks, Namhyung
