Subject: [GIT PULL] Power management updates for v6.3-rc1
Hi Linus,
I'm sending this ahead of time, because I will be traveling next week
and I don't want to delay the integration of the changes below just
because of my absence.
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.3-rc1
with top-most commit dd855f01e8d194d2dfeda36b620203c623c10430
Merge branches 'pm-tools' and 'pm-docs'
on top of commit 6f098cde9df2c86d60db727d6270272751943674
cpufreq: qcom-hw: Add missing null pointer check
to receive power management updates for 6.3-rc1.
These add EPP support to the AMD P-state cpufreq driver, add support for
new platforms to the Intel RAPL power capping driver, intel_idle and the
Qualcomm cpufreq driver, enable thermal cooling for Tegra194, drop the
custom cpufreq driver for loongson1 that is not necessary any more (and
the corresponding cpufreq platform device), fix assorted issues and
clean up code.
Specifics:
- Add EPP support to the AMD P-state cpufreq driver (Perry Yuan, Wyes
Karny, Arnd Bergmann, Bagas Sanjaya).
- Drop the custom cpufreq driver for loongson1 that is not necessary
any more and the corresponding cpufreq platform device (Keguang
Zhang).
- Remove "select SRCU" from system sleep, cpufreq and OPP Kconfig
entries (Paul E. McKenney).
- Enable thermal cooling for Tegra194 (Yi-Wei Wang).
- Register module device table and add missing compatibles for
cpufreq-qcom-hw (Nícolas F. R. A. Prado, Abel Vesa and Luca Weiss).
- Various dt binding updates for qcom-cpufreq-nvmem and opp-v2-kryo-cpu
(Christian Marangi).
- Make kobj_type structure in the cpufreq core constant (Thomas
Weißschuh).
- Make cpufreq_unregister_driver() return void (Uwe Kleine-König).
- Make the TEO cpuidle governor check CPU utilization in order to refine
idle state selection (Kajetan Puchalski).
- Make Kconfig select the haltpoll cpuidle governor when the haltpoll
cpuidle driver is selected and replace a default_idle() call in that
driver with arch_cpu_idle() to allow MWAIT to be used (Li RongQing).
- Add Emerald Rapids Xeon support to the intel_idle driver (Artem
Bityutskiy).
- Add ARCH_SUSPEND_POSSIBLE dependencies for ARMv4 cpuidle drivers to
avoid randconfig build failures (Arnd Bergmann).
- Make kobj_type structures used in the cpuidle sysfs interface
constant (Thomas Weißschuh).
- Make the cpuidle driver registration code update microsecond values
of idle state parameters in accordance with their nanosecond values
if they are provided (Rafael Wysocki).
- Make the PSCI cpuidle driver prevent topology CPUs from being
suspended on PREEMPT_RT (Krzysztof Kozlowski).
- Document that pm_runtime_force_suspend() cannot be used with
DPM_FLAG_SMART_SUSPEND (Richard Fitzgerald).
- Add EXPORT macros for exporting PM functions from drivers (Richard
Fitzgerald).
- Remove /** from non-kernel-doc comments in hibernation code (Randy
Dunlap).
- Fix possible name leak in powercap_register_zone() (Yang Yingliang).
- Add Meteor Lake and Emerald Rapids support to the intel_rapl power
capping driver (Zhang Rui).
- Modify the idle_inject power capping facility to support 100% idle
injection (Srinivas Pandruvada).
- Fix large time windows handling in the intel_rapl power capping
driver (Zhang Rui).
- Fix memory leaks with using debugfs_lookup() in the generic PM
domains and Energy Model code (Greg Kroah-Hartman).
- Add missing 'cache-unified' property in the example for kryo OPP
bindings (Rob Herring).
- Fix error checking in opp_migrate_dentry() (Qi Zheng).
- Let qcom,opp-fuse-level be a 2-long array for qcom SoCs (Konrad
Dybcio).
- Modify some power management utilities to use the canonical ftrace
path (Ross Zwisler).
- Correct spelling problems for Documentation/power/ as reported by
codespell (Randy Dunlap).
Thanks!
