Enable it when such a task is picked, with a selftest. - Smaller fixes: userspace CPU-mask helpers, ratelimited deprecation warnings, docs and a sparse annotation. ---------------------------------------------------------------- Andrea Righi (4): sched_ext: Reset dsq_vtime and slice when a task leaves SCX sched_ext: Preserve rq tracking across local DSQ dispatch sched_ext: Enable tick for finite slices on nohz_full selftests/sched_ext: Verify nohz_full tick behavior Breno Leitao (1): sched_ext: Avoid flooding the log with deprecation warnings Kuba Piecuch (2): sched_ext: Check remote rq eligibility under task's rq lock sched_ext: Skip ops.set_weight() for disabled tasks Liang Luo (1): sched_ext: Documentation: Fix ops table header reference Tejun Heo (6): sched_ext: Annotate ksyncs with __rcu in alloc/free_kick_syncs() sched_ext: Pin parent scx_sched across a child sub-scheduler's lifetime sched_ext: Don't warn on core-sched forced idle in put_prev_task_scx() sched_ext: Record an error on errno-only sub-enable failure sched_ext: Fix premature ops->priv publication in scx_alloc_and_add_sched() tools/sched_ext: scx - Fix cmask_subset(), cmask_equal() and cmask_weight() Documentation/scheduler/sched-ext.rst | 8 +- kernel/sched/ext/ext.c | 177 ++++++++--- kernel/sched/ext/internal.h | 23 +- tools/sched_ext/include/scx/cid.bpf.h | 88 ++++-- tools/testing/selftests/sched_ext/Makefile | 1 + tools/testing/selftests/sched_ext/nohz_tick.bpf.c | 65 ++++ tools/testing/selftests/sched_ext/nohz_tick.c | 347 ++++++++++++++++++++++ 7 files changed, 614 insertions(+), 95 deletions(-) create mode 100644 tools/testing/selftests/sched_ext/nohz_tick.bpf.c create mode 100644 tools/testing/selftests/sched_ext/nohz_tick.c Thanks. -- tejun
