Subject: [GIT PULL] Power management updates for v5.20-rc1
Date: Mon, 1 Aug 2022 21:51:23 +0200	[thread overview]
Message-ID: <> (raw)

Hi Linus,

Please pull from the tag

 git:// \

with top-most commit aa727b7b4b67dba2a6cfebdd98767c455c2b3d69

 Merge branches 'pm-devfreq', 'pm-qos', 'pm-tools' and 'pm-docs'

on top of commit d295ad34f236c3518634fb6403d4c0160456e470

 intel_idle: Fix false positive RCU splats due to incorrect hardirqs state

to receive power management updates for 5.20-rc1.

These mostly are minor improvements all over including new CPU IDs
for the Intel RAPL driver, an Energy Model rework to use micro-Watt
as the power unit, cpufreq fixes and cleanus, cpuidle updates,
devfreq updates, documentation cleanups and a new version of the
pm-graph suite of utilities.


 - Make cpufreq_show_cpus() more straightforward (Viresh Kumar).

 - Drop unnecessary CPU hotplug locking from store() used by cpufreq
   sysfs attributes (Viresh Kumar).

 - Make the ACPI cpufreq driver support the boost control interface on
   Zhaoxin/Centaur processors (Tony W Wang-oc).

 - Print a warning message on attempts to free an active cpufreq policy
   which should never happen (Viresh Kumar).

 - Fix grammar in the Kconfig help text for the loongson2 cpufreq
   driver (Randy Dunlap).

 - Use cpumask_var_t for an on-stack CPU mask in the ondemand cpufreq
   governor (Zhao Liu).

 - Add trace points for guest_halt_poll_ns grow/shrink to the haltpoll
   cpuidle driver (Eiichi Tsukata).

 - Modify intel_idle to treat C1 and C1E as independent idle states on
   Sapphire Rapids (Artem Bityutskiy).

 - Extend support for wakeirq to callback wrappers used during system
   suspend and resume (Ulf Hansson).

 - Defer waiting for device probe before loading a hibernation image
   till the first actual device access to avoid possible deadlocks
   reported by syzbot (Tetsuo Handa).

 - Unify device_init_wakeup() for PM_SLEEP and !PM_SLEEP (Bjorn

 - Add Raptor Lake-P to the list of processors supported by the Intel
   RAPL driver (George D Sworo).

 - Add Alder Lake-N and Raptor Lake-P to the list of processors for
   which Power Limit4 is supported in the Intel RAPL driver (Sumeet

 - Make pm_genpd_remove() check genpd_debugfs_dir against NULL before
   attempting to remove it (Hsin-Yi Wang).

 - Change the Energy Model code to represent power in micro-Watts and
   adjust its users accordingly (Lukasz Luba).

 - Add new devfreq driver for Mediatek CCI (Cache Coherent
   Interconnect) (Johnson Wang).

 - Convert the Samsung Exynos SoC Bus bindings to DT schema of
   exynos-bus.c (Krzysztof Kozlowski).

 - Address kernel-doc warnings by adding the description for unused
   function parameters in devfreq core (Mauro Carvalho Chehab).

 - Use NULL to pass a null pointer rather than zero according to the
   function prototype in imx-bus.c (Colin Ian King).

 - Print error message instead of error integer value in
   tegra30-devfreq.c (Dmitry Osipenko).

 - Add checks to prevent setting negative frequency QoS limits for
   CPUs (Shivnandan Kumar).

 - Update the pm-graph suite of utilities to the latest revision 5.9
   including multiple improvements (Todd Brandt).

 - Drop pme_interrupt reference from the PCI power management
   documentation (Mario Limonciello).
