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

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.

Thanks.

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
