Subject: [RFT][PATCH 0/2] cpufreq: intel_pstate: Handle _PPC updates on global turbo disable/enable
Date: Fri, 01 Mar 2019 13:43:00 +0100 [thread overview]
Message-ID: <9956076.F4luUDm1Dq@aspire.rjw.lan> (raw)
Hi All,
This is how I would fix the issue reported in BZ 200759 (see this patch series
from Yu too: https://marc.info/?l=linux-pm&m=155137672924029&w=2).
Patch [1/2] causes intel_pstate to update all policies if it gets a _PPC change
notification and sees a global turbo disable/enable change.
Patch [2/2] makes it update cpuinfo.max_freq for all policies in those cases.
The patches here have not been tested yet, so testing would be much appreciated.
Of course, comments are welcome too!
Thanks,
Rafael
