I had backport you tick/broadcast: Prefer per-cpu relatives patches, but i did not get the true result, the Wakeup Devices are all null, why?Probably because you don't have any suitable per-cpu timers to act as a wakeup. Do you have a per-cpu timer registered with CLOCK_EVT_FEAT_PERCPU
Yes, you are right, but i want to know why the timer do not support CLOCK_EVT_FEAT_PERCPU.
and CLOCK_EVT_FEAT_ONESHOT but not CLOCK_EVT_FEAT_C3STOP? Will
