Subject: [PATCH v4 0/3] platform/x86/amd/pmf: Introduce CnQF feature for AMD PMF
Date: Thu, 22 Sep 2022 18:41:59 +0530 [thread overview]
Message-ID: <20220922131202.56529-1-Shyam-sundar.S-k@amd.com> (raw)
In this series, support for following features has been added.
- "Cool n Quiet Framework (CnQF)" is an extension to the static slider,
where the system power can be boosted or throttled independent
of the selected slider position.
- On the fly, the CnQF can be turned on/off via a sysfs knob.
v4:
-----------
- update amd_pmf_load_defaults_cnqf() and amd_pmf_init_cnqf() as
suggested by Hans.
- Add a new amd_pmf_cnqf_get_power_source() as a wrapper for
amd_pmf_get_power_source().
- Drop call to amd_pmf_init_sps during sysfs _store() call.
- Fix cosmetic issues
v3:
-----------
- use "is_visible" and ".dev_groups" for sysfs registration and
handling.
- Squash patch 3/4 and 4/4 into one.
- update ABI doc with changes as suggested by Mario.
- Fix amd_pmf_load_defaults_cnqf() error handling.
v2:
-----------
- Enable CnQF only when static slider is set to "balanced" and other
cases
keep it turned off.
