[PATCH 0/8] Flush RSC votes properly on more RPMh platforms
From: Konrad Dybcio
Date: Wed May 31 2023 - 09:22:52 EST
As pointed out in [1], the Linux implementation of RSC basically requires
(even if not explicitly) that we point it to a power domain which
represents the power state of the CPUs. In an effort to fulfill that
requirement, make it required in bindings and hook it up on all platforms
where I was able to do. This means all RPMh platforms, except
- SC7180
- SC7280
- SA8775
As there wasn't an idle-states setup (which may be on purpose for CrOS
devices, certainly not for Windows SC7[12]80s) that I could validate.
(Doug, Bartosz, could you guys look into your respective platforms of
interest here?)
This series also adds support for idle states on SM6350, as I was able
to add and test that.
