[PATCH v2 0/3] SRF: Fix offline CPU preventing pc6 entry
From: Patryk Wlazlyn
Date: Tue Oct 29 2024 - 06:15:41 EST
Sending a tiny change in response to a suggestion I got off-list.
Changes since v1:
* Remove explicit assignment to global, play_dead_mwait_hint as
suggested by Dave Hansen off-list, to prevent compiler from
moving it out of the .bss.
Patryk Wlazlyn (3):
x86/smp: Move mwait hint computation out of mwait_play_dead
x86/smp: Allow forcing the mwait hint for play dead loop
intel_idle: Identify the deepest cstate for SRF
