Subject: [GIT PULL] Power management updates for v5.2-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.2-rc1
with top-most commit e07095c9bbcd296401bec8b6852d258d7c926969
Merge branches 'pm-devfreq' and 'pm-domains'
on top of commit 37624b58542fb9f2d9a70e6ea006ef8a5f66c30b
Linux 5.1-rc7
to receive power management updates for 5.2-rc1.
These fix the (Intel-specific) Performance and Energy Bias Hint (EPB)
handling and expose it to user space via sysfs, fix and clean up
several cpufreq drivers, add support for two new chips to the qoriq
cpufreq driver, fix, simplify and clean up the cpufreq core and the
schedutil governor, add support for "CPU" domains to the generic
power domains (genpd) framework and provide low-level PSCI firmware
support for that feature, fix the exynos cpuidle driver and fix a
couple of issues in the devfreq subsystem and clean it up.
Specifics:
- Fix the handling of Performance and Energy Bias Hint (EPB) on
Intel processors and expose it to user space via sysfs to avoid
having to access it through the generic MSR I/F (Rafael Wysocki).
- Improve the handling of global turbo changes made by the platform
firmware in the intel_pstate driver (Rafael Wysocki).
- Convert some slow-path static_cpu_has() callers to boot_cpu_has()
in cpufreq (Borislav Petkov).
- Fix the frequency calculation loop in the armada-37xx cpufreq
driver (Gregory CLEMENT).
- Fix possible object reference leaks in multuple cpufreq drivers
(Wen Yang).
- Fix kerneldoc comment in the centrino cpufreq driver (dongjian).
- Clean up the ACPI and maple cpufreq drivers (Viresh Kumar, Mohan
Kumar).
- Add support for lx2160a and ls1028a to the qoriq cpufreq driver
(Vabhav Sharma, Yuantian Tang).
- Fix kobject memory leak in the cpufreq core (Viresh Kumar).
- Simplify the IOwait boosting in the schedutil cpufreq governor
and rework the TSC cpufreq notifier on x86 (Rafael Wysocki).
- Clean up the cpufreq core and statistics code (Yue Hu, Kyle Lin).
- Improve the cpufreq documentation, add SPDX license tags to
some PM documentation files and unify copyright notices in
them (Rafael Wysocki).
- Add support for "CPU" domains to the generic power domains (genpd)
framework and provide low-level PSCI firmware support for that
feature (Ulf Hansson).
- Rearrange the PSCI firmware support code and add support for
SYSTEM_RESET2 to it (Ulf Hansson, Sudeep Holla).
- Improve genpd support for devices in multiple power domains (Ulf
Hansson).
- Unify target residency for the AFTR and coupled AFTR states in the
exynos cpuidle driver (Marek Szyprowski).
- Introduce new helper routine in the operating performance points
(OPP) framework (Andrew-sh.Cheng).
- Add support for passing on-die termination (ODT) and auto power
down parameters from the kernel to Trusted Firmware-A (TF-A) to
the rk3399_dmc devfreq driver (Enric Balletbo i Serra).
- Add tracing to devfreq (Lukasz Luba).
- Make the exynos-bus devfreq driver suspend all devices on system
shutdown (Marek Szyprowski).
- Fix a few minor issues in the devfreq subsystem and clean it up
somewhat (Enric Balletbo i Serra, MyungJoo Ham, Rob Herring,
Saravana Kannan, Yangtao Li).
- Improve system wakeup diagnostics (Stephen Boyd).
- Rework filesystem sync messages emitted during system suspend and
hibernation (Harry Pan).
Thanks!
