Subject: [RFC PATCH 0/4] perf/core: Small event scheduling changes


This is an rfc patchset, only compile tested just to ensure I'm taking
a good direction before going ahead.

This is intended to rework a bit the perf event scheduling to
guarantee a real priority of the pinned events over the volatile
ones. This patchset handles such priority on task tick time
only. But if the idea is agreed, I could expand that to every
task event sched-in calls to guarantee the priority in every
event rescheduling time.


Frederic Weisbecker (4):
  perf/core: split context's event group list into pinned and
    non-pinned lists
  perf/core: Optimize a bit rotate_ctx()
  perf/core: Split up pinned and non pinned processing
  perf/core: Schedule every pinned events before the the non-pinned
