This patch series introduces changes to add default build support for the sched tests in selftests. The only test under sched is cs_prctl_test which validates cookies when core scheduling is in effect. This test fails on systems where core scheduling is disabled. The patch series also modifies this behaviour to gracefully skip the test on such systems. A system with core scheduling disabled would skip the test like: ~# ./run_kselftest.sh TAP version 13 1..1 timeout set to 45 selftests: sched: cs_prctl_test prctl failed: Invalid argument Core sched not supported, hence skipping tests ok 1 selftests: sched: cs_prctl_test # SKIP Signed-off-by: Sinadin Shan <sinadin.shan@xxxxxxxxxx> --- v3: * Use prctl to check core sched support instead of config * v2 link: https://lore.kernel.org/all/20250221115750.631990-1-sinadin.shan@xxxxxxxxxx/ v2: * Add patch to skip cs_prctl_test on core scheduling disabled systems * v1 link: https://lore.kernel.org/all/20250219064658.449069-1-sinadin.shan@xxxxxxxxxx --- Sinadin Shan (2): selftests: sched: add sched as a default selftest target selftests: sched: skip cs_prctl_test for systems with core scheduling disabled tools/testing/selftests/Makefile | 1 + tools/testing/selftests/sched/cs_prctl_test.c | 34 ++++++++++++++++++- 2 files changed, 34 insertions(+), 1 deletion(-) -- 2.43.5
