Test Details: ============= Test Path: linux/tools/testing/selftests/sched_ext Test Name: select_cpu_dfl_nodispatch Command: ./runner -t select_cpu_dfl_nodispatch Test Description: ================ The test is designed to verify the behavior of scx_bpf_select_cpu_dfl() in ops.select_cpu() Failure Details: ================ The test fails with the following output: ./runner -t select_cpu_dfl_nodispatch ===== START ===== TEST: select_cpu_dfl_nodispatch DESCRIPTION: Verify behavior of scx_bpf_select_cpu_dfl() in ops.select_cpu() OUTPUT: ERR: select_cpu_dfl_nodispatch.c:53 Expected skel->bss->saw_local to be true (0) not ok 1 select_cpu_dfl_nodispatch # =====  END  ===== RESULTS: PASSED:  0 SKIPPED: 0 FAILED:  1 Reproduction: ============= 1. Clone the upstream Linux kernel repository 2. Enable CONFIG_SCHED_CLASS_EXT in kernel configuration 3. Build and boot the kernel with sched_ext enabled 4. Navigate to linux/tools/testing/selftests/sched_ext 5. Build the selftests: make 6. Run the test: ./runner -t select_cpu_dfl_nodispatch Environment: ============ Kernel Version: 7.0.0-rc7 Architecture: ppc64le Could you please investigate this test failure? I'm happy to provide additional information or test on different configurations if needed. If you happen to fix the above issue, then please add below tag. Reported-by: Samir M Regards, Samir.
