Subject: [GIT PULL] Power management updates for v5.17-rc1
Date: Mon, 10 Jan 2022 20:16:29 +0100	[thread overview]
Message-ID: <> (raw)

Hi Linus,

Please pull from the tag

 git:// \

with top-most commit 78e6e4dfd8f0cbb477a6f9571123edcbd5873c28

 Merge branches 'pm-opp', 'pm-devfreq' and 'powercap'

on top of commit c9e6606c7fe92b50a02ce51dda82586ebdf99b48

 Linux 5.16-rc8

to receive power management updates for 5.17-rc1.

The most signigicant change here is the addition of a new cpufreq
"P-state" driver for AMD processors as a better replacement for
the venerable acpi-cpufreq driver.  There are also other cpufreq
updates (in the core, intel_pstate, ARM drivers), PM core updates
(mostly related to adding new macros for declaring PM operations
which should make the lives of driver developers somewhat easier),
and a bunch of assorted fixes and cleanups.


 - Add new P-state driver for AMD processors (Huang Rui).

 - Fix initialization of min and max frequency QoS requests in the
   cpufreq core (Rafael Wysocki).

 - Fix EPP handling on Alder Lake in intel_pstate (Srinivas Pandruvada).

 - Make intel_pstate update cpuinfo.max_freq when notified of HWP
   capabilities changes and drop a redundant function call from that
   driver (Rafael Wysocki).

 - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
   Stephen Boyd, Vladimir Zapolskiy).

 - Fix double devm_remap() in the Mediatek cpufreq driver (Hector Yuan).

 - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz

 - Make cpufreq use default_groups in kobj_type (Greg Kroah-Hartman).

 - Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).

 - Fix two comments in cpuidle code (Jason Wang, Yang Li).

 - Allow model-specific normal EPB value to be used in the intel_epb
   sysfs attribute handling code (Srinivas Pandruvada).

 - Simplify locking in pm_runtime_put_suppliers() (Rafael Wysocki).

 - Add safety net to supplier device release in the runtime PM core
   code (Rafael Wysocki).

 - Capture device status before disabling runtime PM for it (Rafael

 - Add new macros for declaring PM operations to allow drivers to
   avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
   update some drivers to use these macros (Paul Cercueil).

 - Allow ACPI hardware signature to be honoured during restore from
   hibernation (David Woodhouse).

 - Update outdated operating performance points (OPP) documentation
   (Tang Yizhou).

 - Reduce log severity for informative message regarding frequency
   transition failures in devfreq (Tzung-Bi Shih).

 - Add DRAM frequency controller devfreq driver for Allwinner sunXi
   SoCs (Samuel Holland).

 - Add missing COMMON_CLK dependency to sun8i devfreq driver (Arnd

 - Add support for new layout of Psys PowerLimit Register on SPR to
   the Intel RAPL power capping driver (Zhang Rui).

 - Fix typo in a comment in idle_inject.c (Jason Wang).

 - Remove unused function definition from the DTPM (Dynamit Thermal
   Power Management) power capping framework (Daniel Lezcano).

 - Reduce DTPM trace verbosity (Daniel Lezcano).
