Subject: [GIT PULL] Power management updates for v6.10-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.10-rc1
with top-most commit de1c2722e07819c7ea65bb4bf37a2cfe2556095b
Merge branches 'pm-em' and 'pm-docs'
on top of commit dd5a440a31fae6e459c0d6271dddd62825505361
Linux 6.9-rc7
to receive power management updates for 6.10-rc1.
These are mostly cpufreq updates, including a significant intel-pstate
driver update and several amd-pstate improvements plus some updates of
ARM cpufreq drivers, general fixes and cleanups.
Also included are changes related to system sleep, power capping updates
adding support for a new platform and a new hardware feature (among other
things), a Samsung exynos-asv driver update allowing it to change its
Energy Model after adjusting voltage, minor cpuidle and devfreq updates
and a small documentation cleanup.
Specifics:
- Rework the handling of disabled turbo in the intel_pstate driver and
make it update the maximum CPU frequency consistently regardless of
the reason on top of a number of cleanups (Rafael Wysocki).
- Add missing checks for NULL .exit() cpufreq driver callback to the
cpufreq core (Viresh Kumar).
- Prevent pulicy->max from going above the frequency QoS maximum value
when cpufreq_frequency_table_verify() is used (Xuewen Yan).
- Prevent a negative CPU number or frequency value from being printed
if they are really large (Joshua Yeong).
- Update MAINTAINERS entry for amd-pstate to add two new submaintainers
and a designated reviewer (Huang Rui).
- Clean up the amd-pstate driver and update its documentation (Gautham
Shenoy).
- Fix the highest frequency issue in the amd-pstate driver which limits
performance (Perry Yuan).
- Enable CPPC v2 for certain processors in the family 17H, as requested
by TR40 processor users who expect improved performance and lower
system temperature (Perry Yuan).
- Change latency and delay values to be read from platform firmware
firstly for more accurate timing (Perry Yuan).
- A new quirk is introduced for supporting amd-pstate on legacy
processors which either lack CPPC capability, or only only have CPPC
v2 capability (Perry Yuan).
- Sun50i cpufreq: Add support for opp_supported_hw, H616 platform and
general cleanups (Andre Przywara, Martin Botka, Brandon Cheo Fusi,
Dan Carpenter, Viresh Kumar).
- CPPC cpufreq: Fix possible null pointer dereference (Aleksandr
Mishin).
- Eliminate uses of of_node_put() from cpufreq (Javier Carrasco,
Shivani Gupta).
- brcmstb-avs: ISO C90 forbids mixed declarations (Portia Stephens).
- mediatek cpufreq: Add support for MT7988A (Sam Shih).
- cpufreq-qcom-hw: Add SM4450 compatibles in DT bindings (Tengfei Fan).
- Fix struct cpudata::epp_cached kernel-doc in the intel_pstate cpufreq
driver (Jeff Johnson).
- Fix kerneldoc description of ladder_do_selection() (Jeff Johnson).
- Convert the cpuidle kirkwood driver to platform remove callback
returning void (Yangtao Li).
- Replace deprecated strncpy() with strscpy() in the hibernation core
code (Justin Stitt).
- Use %ps to simplify debug output in the core system-wide suspend and
resume code (Len Brown).
- Remove unnecessary else from device_init_wakeup() and make
device_wakeup_disable() return void (Dhruva Gole).
- Enable PMU support in the Intel TPMI RAPL driver (Zhang Rui).
- Add support for ArrowLake-H platform to the Intel RAPL driver (Zhang
Rui).
- Avoid explicit cpumask allocation on stack in DTPM (Dawei Li).
- Make the Samsung exynos-asv driver update the Energy Model after
adjusting voltage on top of some preliminary changes of the OPP and
Enery Model generic code (Lukasz Luba).
- Remove a reference to a function that has been dropped from the power
management documentation (Bjorn Helgaas).
- Convert the platfrom remove callback to .remove_new for the
exyno-nocp, exynos-ppmu, mtk-cci-devfreq, sun8i-a33-mbus, and
rk3399_dmc devfreq drivers (Uwe Kleine-König).
- Use DEFINE_SIMPLE_PM_OPS for exyno-bus.c driver (Anand Moon).
Thanks!
