tools/tracing/rtla/tests/scripts/lib/get_workload_pids.sh is for some reason not finding the user threads (as the tests for -H and -k succeeded) on your system. The threads themselves had to be running, as timerlat is reporting samples from them. The script and the related tests cases were added in 7.2 already, this pull request does not touch them so it's most likely a pre-existing issue. Either way, I will look into that, thank you for testing. It might be environment-dependent, as the test relies on the test script (executed as an --on-threshold action) being a direct child of the main rtla process - which only holds when the system() shell executes the script directly, not as a subprocess.I just pushed this to the for-next branch. I'll let you figure out if there needs to be any more updates. -- Steve
Thanks. As this is now a known bug in the test (and is already in 7.2 rather than a 7.3 regression in the pull request), I was not rushing to fix that and rather continued to focus on my patchset. Of course, I'm trying to keep tests passing, now that the majority of high-frequency intermittent failures are fixed, so that people running tests are not desensitized to failures. Tomas
