Subject: [GIT PULL] Power management updates for v5.8-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.8-rc1
with top-most commit a34024d98eeaa78e2cd22017180df778800b83fc
Merge branches 'pm-devfreq', 'powercap', 'pm-docs' and 'pm-tools'
on top of commit 9cb1fd0efd195590b828b9b865421ad345a4a145
Linux 5.7-rc7
to receive power management updates for 5.8-rc1.
These rework the system-wide PM driver flags, make runtime switching
of cpuidle governors easier, improve the user space hibernation
interface code, add intel-speed-select interface documentation,
add more debug messages to the ACPI code handling suspend to idle,
update the cpufreq core and drivers, fix a minor issue in the
cpuidle core and update two cpuidle drivers, improve the PM-runtime
framework, update the Intel RAPL power capping driver, update devfreq
core and drivers, and clean up the cpupower utility.
Specifics:
- Rework the system-wide PM driver flags to make them easier to
understand and use and update their documentation (Rafael Wysocki,
Alan Stern).
- Allow cpuidle governors to be switched at run time regardless of
the kernel configuration and update the related documentation
accordingly (Hanjun Guo).
- Improve the resume device handling in the user space hibernation
interface code (Domenico Andreoli).
- Document the intel-speed-select sysfs interface (Srinivas
Pandruvada).
- Make the ACPI code handing suspend to idle print more debug
messages to help diagnose issues with it (Rafael Wysocki).
- Fix a helper routine in the cpufreq core and correct a typo in
the struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
Wenhu).
- Update cpufreq drivers:
* Make the intel_pstate driver start in the passive mode by
default on systems without HWP (Rafael Wysocki).
* Add i.MX7ULP support to the imx-cpufreq-dt driver and add
i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
* Convert the qoriq cpufreq driver to a platform one, make the
platform code create a suitable device object for it and add
platform dependencies to it (Mian Yousaf Kaukab, Geert
Uytterhoeven).
* Fix wrong compatible binding in the qcom driver (Ansuel Smith).
* Build the omap driver by default for ARCH_OMAP2PLUS (Anders
Roxell).
* Add r8a7742 SoC support to the dt cpufreq driver (Lad Prabhakar).
- Update cpuidle core and drivers:
* Fix three reference count leaks in error code paths in the
cpuidle core (Qiushi Wu).
* Convert Qualcomm SPM to a generic cpuidle driver (Stephan
Gerhold).
* Fix up the execution order when entering a domain idle state in
the PSCI driver (Ulf Hansson).
- Fix a reference counting issue related to clock management and
clean up two oddities in the PM-runtime framework (Rafael Wysocki,
Andy Shevchenko).
- Add ElkhartLake support to the Intel RAPL power capping driver
and remove an unused local MSR definition from it (Jacob Pan,
Sumeet Pawnikar).
- Update devfreq core and drivers:
* Replace strncpy() with strscpy() in the devfreq core and use
lockdep asserts instead of manual checks for a locked mutex in
it (Dmitry Osipenko, Krzysztof Kozlowski).
* Add a generic imx bus scaling driver and make it register an
interconnect device (Leonard Crestez, Gustavo A. R. Silva).
* Make the cpufreq notifier in the tegra30 driver take boosting
into account and delete an unuseful error message from that
driver (Dmitry Osipenko, Markus Elfring).
- Remove unneeded semicolon from the cpupower code (Zou Wei).
There is a merge conflict between this update and the drm tree which
was addressed in linux-next by applying the appended diff.
Thanks!
