Subject[PATCHSET 0/8] perf test: Improve perf record tests (v2)
Date
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
