Subject: [GIT PULL] Power management updates for v5.11-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.11-rc1
with top-most commit b3fac817830306328d5195e7f4fb332277f3b146
Merge branches 'pm-devfreq' and 'pm-tools'
on top of commit 0477e92881850d44910a7e94fc2c46f96faa131f
Linux 5.10-rc7
to receive power management updates for 5.11-rc1.
These update cpufreq (core and drivers), cpuidle (polling state
implementation and the PSCI driver), the OPP (operating performance
points) framework, devfreq (core and drivers), the power capping RAPL
(Running Average Power Limit) driver, the Energy Model support, the
generic power domains (genpd) framework, the ACPI device power
management, the core system-wide suspend code and power management
utilities.
Specifics:
- Use local_clock() instead of jiffies in the cpufreq statistics to
improve accuracy (Viresh Kumar).
- Fix up OPP usage in the cpufreq-dt and qcom-cpufreq-nvmem cpufreq
drivers (Viresh Kumar).
- Clean up the cpufreq core, the intel_pstate driver and the
schedutil cpufreq governor (Rafael Wysocki).
- Fix up error code paths in the sti-cpufreq and mediatek cpufreq
drivers (Yangtao Li, Qinglang Miao).
- Fix cpufreq_online() to return error codes instead of success (0)
in all cases when it fails (Wang ShaoBo).
- Add mt8167 support to the mediatek cpufreq driver and blacklist
mt8516 in the cpufreq-dt-platdev driver (Fabien Parent).
- Modify the tegra194 cpufreq driver to always return values from
the frequency table as the current frequency and clean up that
driver (Sumit Gupta, Jon Hunter).
- Modify the arm_scmi cpufreq driver to allow it to discover the
power scale present in the performance protocol and provide this
information to the Energy Model (Lukasz Luba).
- Add missing MODULE_DEVICE_TABLE to several cpufreq drivers (Pali
Rohár).
- Clean up the CPPC cpufreq driver (Ionela Voinescu).
- Fix NVMEM_IMX_OCOTP dependency in the imx cpufreq driver (Arnd
Bergmann).
- Rework the poling interval selection for the polling state in
cpuidle (Mel Gorman).
- Enable suspend-to-idle for PSCI OSI mode in the PSCI cpuidle
driver (Ulf Hansson).
- Modify the OPP framework to support empty (node-less) OPP tables
in DT for passing dependency information (Nicola Mazzucato).
- Fix potential lockdep issue in the OPP core and clean up the OPP
core (Viresh Kumar).
- Modify dev_pm_opp_put_regulators() to accept a NULL argument and
update its users accordingly (Viresh Kumar).
- Add frequency changes tracepoint to devfreq (Matthias Kaehlcke).
- Add support for governor feature flags to devfreq, make devfreq
sysfs file permissions depend on the governor and clean up the
devfreq core (Chanwoo Choi).
- Clean up the tegra20 devfreq driver and deprecate it to allow
another driver based on EMC_STAT to be used instead of it (Dmitry
Osipenko).
- Add interconnect support to the tegra30 devfreq driver, allow it
to take the interconnect and OPP information from DT and clean it
up ((Dmitry Osipenko).
- Add interconnect support to the exynos-bus devfreq driver along
with interconnect properties documentation (Sylwester Nawrocki).
- Add suport for AMD Fam17h and Fam19h processors to the RAPL power
capping driver (Victor Ding, Kim Phillips).
- Fix handling of overly long constraint names in the powercap
framework (Lukasz Luba).
- Fix the wakeup configuration handling for bridges in the ACPI
device power management core (Rafael Wysocki).
- Add support for using an abstract scale for power units in the
Energy Model (EM) and document it (Lukasz Luba).
- Add em_cpu_energy() micro-optimization to the EM (Pavankumar
Kondeti).
- Modify the generic power domains (genpd) framwework to support
suspend-to-idle (Ulf Hansson).
- Fix creation of debugfs nodes in genpd (Thierry Strudel).
- Clean up genpd (Lina Iyer).
- Clean up the core system-wide suspend code and make it print
driver flags for devices with debug enabled (Alex Shi, Patrice
Chotard, Chen Yu).
- Modify the ACPI system reboot code to make it prepare for system
power off to avoid confusing the platform firmware (Kai-Heng Feng).
- Update the pm-graph (multiple changes, mostly usability-related)
and cpupower (online and offline CPU information support) PM
utilities (Todd Brandt, Brahadambal Srinivasan).
