Subject: [GIT PULL] Power management updates for v5.16-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.16-rc1
with top-most commit bf56b90797c4a03c94b702c50e62296edea9fad9
Merge branches 'pm-em' and 'powercap'
on top of commit 3906fe9bb7f1a2c8667ae54e967dc8690824f4ea
Linux 5.15-rc7
to receive power management updates for 5.16-rc1.
These make the power management of PCI devices with ACPI companions
more straightforwad, add support for inefficient operating performance
points to the Energy model and make cpufreq handle them as appropriate,
rearrange the handling of cpuidle during system PM transitions,
update a few cpufreq drivers and intel_idle, fix assorded issues and
clean up code in multiple places.
Specifics:
- Add support for inefficient operating performance points to the
Energy Model and modify cpufreq to use them properly (Vincent
Donnefort).
- Rearrange the DTPM framework code to simplify it and make it easier
to follow (Daniel Lezcano).
- Fix power intialization in DTPM (Daniel Lezcano).
- Add CPU load consideration when estimating the instaneous power
consumption in DTPM (Daniel Lezcano).
- Fix cpu->pstate.turbo_freq initialization in intel_pstate (Zhang
Rui).
- Make intel_pstate process HWP Guaranteed change notifications from
the processor (Srinivas Pandruvada).
- Fix typo in cpufreq.h (Rafael Wysocki).
- Fix tegra driver to handle BPMP errors properly (Mikko Perttunen).
- Fix the parameter usage of the newly added perf-domain API (Hector
Yuan).
- Minor cleanups to cppc, vexpress and s3c244x drivers (Han Wang,
Guenter Roeck, and Arnd Bergmann).
- Fix kobject memory leaks in cpuidle error paths (Anel Orazgaliyeva).
- Make intel_idle enable interrupts before entering C1 on some Xeon
processor models (Artem Bityutskiy).
- Clean up hib_wait_io() (Falla Coulibaly).
- Fix sparse warnings in hibernation-related code (Anders Roxell).
- Use vzalloc() and kzalloc() instead of their open-coded
equivalents in hibernation-related code (Cai Huoqing).
- Prevent user space from crashing the kernel by attempting to
restore the system state from a swap partition in use (Ye Bin).
- Do not let "syscore" devices runtime-suspend during system PM
transitions (Rafael Wysocki).
- Do not pause cpuidle in the suspend-to-idle path (Rafael Wysocki).
- Pause cpuidle later and resume it earlier during system PM
transitions (Rafael Wysocki).
- Make system suspend code use valid_state() consistently (Rafael
Wysocki).
- Add support for enabling wakeup IRQs after invoking the
->runtime_suspend() callback and make two drivers use it (Chunfeng
Yun).
- Make the association of ACPI device objects with PCI devices more
straightforward and simplify the code doing that for all devices
in general (Rafael Wysocki).
- Eliminate struct pci_platform_pm_ops and handle the both of its
users (PCI and Intel MID) directly in the PCI bus code (Rafael
Wysocki).
- Simplify and clarify ACPI PCI device PM helpers (Rafael Wysocki).
- Fix ordering of operations in pci_back_from_sleep() (Rafael
Wysocki).
- Make exynos-ppmu use hyphens in DT properties (Krzysztof
Kozlowski).
- Simplify parsing event-type from DT in exynos-ppmu (Krzysztof
Kozlowski).
- Strengthen check for freq_table in devfreq (Samuel Holland).
Some of the changes listed above are also present in the ACPI updates
pull request sent earlier due to dependencies between the ACPI "glue"
code and the PCI device PM changes.
Thanks!
