Subject: [GIT PULL] Power management updates for v5.17-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.17-rc1
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.
Specifics:
- 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
Luba).
- 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
Wysocki).
- 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- Update outdated operating performance points (OPP) documentation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
Bergmann).
- 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).
Thanks!
