[PATCH 0/2] cpufreq/amd-pstate register write fixes
From: Christian Loehle
Date: Thu Oct 29 2026 - 08:22:13 EST
Two issues that popped up when trying to integrate an AMD machine into
my testing for acpi-cppc, in particular for this (otherwise
unrelated) patch:
https://lore.kernel.org/lkml/20261020121846.691218-2-sumitg@xxxxxxxxxx/
The first is rather straightforward, I think the case was just not
considered during the refactor of the Fixes commit.
The second is part of the resume handling and was introduced when
that restored the register values (DESIRED derived from policy->cur).
My platform seems to handle it well, but it's still strange
behaviour, so why not fix it.
(Also of course the resume value will generally be overwritten and
therefore 'fixed' anyway.)
Christian Loehle (2):
cpufreq/amd-pstate: Keep minimum requests within policy limits
cpufreq/amd-pstate: Clamp desired perf on resume
