sched_ext: Update selftests to drop ops.cpu_acquire/release()

2026-03-15T08:54:05+00:00

ops.cpu_acquire/release() are deprecated by commit a3f5d4822253 ("sched_ext: Allow scx_bpf_reenqueue_local() to be called from anywhere") in favor of handling CPU preemption via the sched_switch tracepoint. In the maximal selftest, replace the cpu_acquire/release stubs with a minimal sched_switch TP program. Attach all non-struct_ops programs (including the new TP) via maximal__attach() after disabling auto-attach for the maximal_ops struct_ops map, which is managed manually in run(). Apply the same fix to reload_loop, which also uses the maximal skeleton. Signed-off-by: Cheng-Yang Chou Reviewed-by: Andrea Righi Signed-off-by: Tejun Heo

selftests/sched_ext: Fix enum resolution

2025-01-24T18:09:52+00:00

All scx enums are now automatically generated from vmlinux.h and they must be initialized using the SCX_ENUM_INIT() macro. Fix the scx selftests to use this macro to properly initialize these values.
