[PATCH] selftests/resctrl: Fix incorrect error return on test complete

by Reinette Chatre

An error snuck in between two recent conflicting changes: Until recently ->setup() used negative values to indicate normal test termination. This was changed in commit fa10366cc6f4 ("selftests/resctrl: Allow ->setup() to return errors") that transitioned ->setup() to use negative values to indicate errors and a new END_OF_TESTS to indicate normal termination. commit 42e3b093eb7c ("selftests/resctrl: Fix set up schemata with 100% allocation on first run in MBM test") continued to use negative return to indicate normal test termination. Fix mbm_setup() to use the new END_OF_TESTS to indicate error-free test termination. Fixes: 42e3b093eb7c ("selftests/resctrl: Fix set up schemata with 100% allocation on first run in MBM test") Reported-by: Ilpo Järvinen <ilpo.jarvinen(a)linux.intel.com> Link: https://lore.kernel.org/lkml/bb65cce8-54d7-68c5-ef19-3364ec95392a@linux.int… Signed-off-by: Reinette Chatre <reinette.chatre(a)intel.com> --- Hi Shuah, Apologies, this error snuck in between the two series merged into kselftest's next this week. tools/testing/selftests/resctrl/mbm_test.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/resctrl/mbm_test.c b/tools/testing/selftests/resctrl/mbm_test.c index 146132fa986d..538d35a6485a 100644 --- a/tools/testing/selftests/resctrl/mbm_test.c +++ b/tools/testing/selftests/resctrl/mbm_test.c @@ -98,7 +98,7 @@ static int mbm_setup(int num, ...) /* Run NUM_OF_RUNS times */ if (p->num_of_runs >= NUM_OF_RUNS) - return -1; + return END_OF_TESTS; /* Set up shemata with 100% allocation on the first run. */ if (p->num_of_runs == 0) -- 2.34.1

[PATCH v9 0/6] Some improvements of resctrl selftest

by Shaopeng Tan

Hello Reinette, The aim of this patch series is to improve the resctrl selftest. Without these fixes, some unnecessary processing will be executed and test results will be confusing. There is no behavior change in test themselves. [patch 1] Make write_schemata() run to set up shemata with 100% allocation on first run in MBM test. [patch 2] The MBA test result message is always output as "ok", make output message to be "not ok" if MBA check result is failed. [patch 3] When a child process is created by fork(), the buffer of the parent process is also copied. Flush the buffer before executing fork(). [patch 4] An error occurs whether in parents process or child process, the parents process always kills child process and runs umount_resctrlfs(), and the child process always waits to be killed by the parent process. [patch 5] If a signal received, to cleanup properly before exiting the parent process, commonize the signal handler registered for CMT/MBM/MBA tests and reuse it in CAT, also unregister the signal handler at the end of each test. [patch 6] Before exiting each test CMT/CAT/MBM/MBA, clear test result files function cat/cmt/mbm/mba_test_cleanup() are called twice. Delete once.

[PATCH 0/3] kunit: Fix reporting of the skipped parameterized tests

by Michal Wajdeczko

Due to the lack of the SKIP directive in the output, if any of the parameterized test was skipped, the parser could not recognize that correctly and was marking the test as PASSED. This can easily be seen by running the new subtest from patch 1: $ ./tools/testing/kunit/kunit.py run \ --kunitconfig ./lib/kunit/.kunitconfig *.example_params* [ ] Starting KUnit Kernel (1/1)...

[PATCH] selftests/mm: Replace obsolete memalign() with posix_memalign()

by Deming Wang

memalign() is obsolete according to its manpage. Replace memalign() with posix_memalign(). As a pointer is passed into posix_memalign(),initialize *map to NULL,to silence a warning about the function's return value being used as uninitialized (which is not valid anyway because the error is properly checked before map is returned).
