Subject: [GIT PULL] Power management updates for v4.21-rc1
Hi Linus,
This goes early due to the upcoming holidays period.
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.21-rc1
with top-most commit a465d38fa3dce6a0dc2d5814cb3aa7b0d2982c6b
Merge branches 'pm-devfreq', 'pm-avs' and 'pm-tools'
on top of commit 7566ec393f4161572ba6f11ad5171fd5d59b0fbd
Linux 4.20-rc7
to receive power management updates for 4.21-rc1.
These add sysadmin documentation for cpuidle, extend the cpuidle
subsystem somewhat, improve the handling of performance states in
the generic power domains (genpd) and operating performance points
(OPP) frameworks, add a new cpufreq driver for Qualcomm SoCs, update
some other cpufreq drivers, switch over the runtime PM framework to
using high-res timers for device autosuspend, fix a problem with
suspend-to-idle on ACPI-based platforms, add system-wide suspend
and resume handling to the devfreq framework, do some janitorial
cleanups all over and update some utilities.
Specifics:
- Add sysadmin documentation for cpuidle (Rafael Wysocki).
- Make it possible to specify a cpuidle governor from kernel
command line, add new cpuidle state sysfs attributes for
governor evaluation, and improve the "polling" idle state
handling (Rafael Wysocki).
- Fix the handling of the "required-opps" DT property in the
operating performance points (OPP) framework, improve the
integration of it with the generic power domains (genpd)
framework, improve the handling of performance states in
them and clean up the idle states vs performance states
separation in genpd (Viresh Kumar, Ulf Hansson).
- Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
a hardware engine to control CPU frequency transitions along
with DT bindings for it (Taniya Das).
- Fix an intel_pstate driver issue related to CPU offline and
update the documentation of it (Srinivas Pandruvada).
- Clean up the imx6q cpufreq driver (Anson Huang).
- Add SPDX license IDs to cpufreq schedutil governor files (Daniel
Lezcano).
- Switch over the runtime PM framework to using high-res timers
for device autosuspend to allow the control of it to be more
precise (Vincent Guittot).
- Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
don't prevent the system from reaching the target low-power state
and simplify the suspend-to-idle handling on ACPI platforms
without full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
- Add system-wide suspend and resume support to the devfreq
framework (Lukasz Luba).
- Clean up the SmartReflex adaptive voltage scaling (AVS) driver and
add an SPDX license ID to it (Nishanth Menon, Uwe Kleine-König,
Thomas Meyer).
- Get rid of code duplication by using the DEFINE_SHOW_ATTRIBUTE
macro in some places, fix some DT node refcount leaks, and do
some other janitorial cleanups (Yangtao Li).
- Update the cpupower, intel_pstate_tracer and turbosat utilities
(Abhishek Goel, Doug Smythies, Len Brown).
Thanks!
