Subject: [PATCH v2 0/3] SRF: Fix offline CPU preventing pc6 entry
Date: Tue, 29 Oct 2024 11:15:04 +0100 [thread overview]
Message-ID: <20241029101507.7188-1-patryk.wlazlyn@linux.intel.com> (raw)
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
