When running tests on a CI system (e.g. LAVA) it is useful to output test results in TAP (Test Anything Protocol) format so that the CI can parse the fine-grained results to show regressions. Many of the mm selftest binaries already output using the TAP format. And the kselftests runner (run_kselftest.sh) also uses the format. CI systems such as LAVA can already handle nested TAP reports. However, with the mm selftests we have 3 levels of nesting (run_kselftest.sh -> run_vmtests.sh -> individual test binaries) and the middle level did not previously support TAP, which breaks the parser. Let's fix that by teaching run_vmtests.sh to output using the TAP format. Ideally this would be opt-in via a command line argument to avoid the possibility of breaking anyone's existing scripts that might scrape the output. However, it is not possible to pass arguments to tests invoked via run_kselftest.sh. So I've implemented an opt-out option (-n), which will revert to the existing output format. Future changes to this file should be aware of 2 new conventions: - output that is part of the TAP reporting is piped through tap_output - general output is piped through tap_prefix Link: https://lkml.kernel.org/r/20231214162434.3580009-1-ryan.roberts@arm.com Signed-off-by: Ryan Roberts <ryan.roberts@arm.com> Reviewed-by: Mark Brown <broonie@kernel.org> Tested-by: John Hubbard <jhubbard@nvidia.com> Cc: Aishwarya TCV <aishwarya.tcv@arm.com> Cc: Peter Xu <peterx@redhat.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |
