Subject: [GIT PULL] Power management updates for v5.19-rc1
Date: Mon, 23 May 2022 21:42:22 +0200	[thread overview]
Message-ID: <> (raw)

Hi Linus,

Please pull from the tag

 git:// \

with top-most commit 0d64482bf29917e659c556aa36cea241b17c33df

 Merge branch 'pm-tools'

on top of commit 42226c989789d8da4af1de0c31070c96726d990c

 Linux 5.18-rc7

to receive power management updates for 5.19-rc1.

These add support for "artificial" Energy Models in which power numbers
for different entities may be in different scales, add support for some
new hardware, fix bugs and clean up code in multiple places.


 - Update the Energy Model support code to allow the Energy Model to be
   artificial, which means that the power values may not be on a uniform
   scale with other devices providing power information, and update the
   cpufreq_cooling and devfreq_cooling thermal drivers to support
   artificial Energy Models (Lukasz Luba).

 - Make DTPM check the Energy Model type (Lukasz Luba).

 - Fix policy counter decrementation in cpufreq if Energy Model is in
   use (Pierre Gondois).

 - Add CPU-based scaling support to passive devfreq governor (Saravana
   Kannan, Chanwoo Choi).

 - Update the rk3399_dmc devfreq driver (Brian Norris).

 - Export dev_pm_ops instead of suspend() and resume() in the IIO
   chemical scd30 driver (Jonathan Cameron).

 - Add namespace variants of EXPORT[_GPL]_SIMPLE_DEV_PM_OPS and
   PM-runtime counterparts (Jonathan Cameron).

 - Move symbol exports in the IIO chemical scd30 driver into the
   IIO_SCD30 namespace (Jonathan Cameron).

 - Avoid device PM-runtime usage count underflows (Rafael Wysocki).

 - Allow dynamic debug to control printing of PM messages  (David

 - Fix some kernel-doc comments in hibernation code (Yang Li, Haowen

 - Preserve ACPI-table override during hibernation (Amadeusz Sławiński).

 - Improve support for suspend-to-RAM for PSCI OSI mode (Ulf Hansson).

 - Make Intel RAPL power capping driver support the RaptorLake and
   AlderLake N processors (Zhang Rui, Sumeet Pawnikar).

 - Remove redundant store to value after multiply in the RAPL power
   capping driver (Colin Ian King).

 - Add AlderLake processor support to the intel_idle driver (Zhang Rui).

 - Fix regression leading to no genpd governor in the PSCI cpuidle
   driver and fix the riscv-sbi cpuidle driver to allow a genpd
   governor to be used (Ulf Hansson).

 - Fix cpufreq governor clean up code to avoid using kfree() directly
   to free kobject-based items (Kevin Hao).

 - Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe Leroy).

 - Make intel_pstate notify frequency invariance code when no_turbo is
   turned on and off (Chen Yu).

 - Add Sapphire Rapids OOB mode support to intel_pstate (Srinivas

 - Make cpufreq avoid unnecessary frequency updates due to mismatch
   between hardware and the frequency table (Viresh Kumar).

 - Make remove_cpu_dev_symlink() clear the real_cpus mask to simplify
   code (Viresh Kumar).

 - Rearrange cpufreq_offline() and cpufreq_remove_dev() to make the
   calling convention for some driver callbacks consistent (Rafael

 - Avoid accessing half-initialized cpufreq policies from the show()
   and store() sysfs functions (Schspa Shi).

 - Rearrange cpufreq_offline() to make the calling convention for some
   driver callbacks consistent (Schspa Shi).

 - Update CPPC handling in cpufreq (Pierre Gondois).

 - Extend dev_pm_domain_detach() doc (Krzysztof Kozlowski).

 - Move genpd's time-accounting to ktime_get_mono_fast_ns() (Ulf

 - Improve the way genpd deals with its governors (Ulf Hansson).

 - Update the turbostat utility to version 2022.04.16 (Len Brown,
   Dan Merillat, Sumeet Pawnikar, Zephaniah E. Loss-Cutler-Hull, Chen
