Subject: [GIT PULL] Power management updates for v4.12-rc1, part 1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.12-rc1
with top-most commit a1d2fcfd80bef6cdc5675dcabe25587010720bdb
Merge branch 'pm-tools'
on top of commit 5a7ad1146caa895ad718a534399e38bd2ba721b7
Linux 4.11-rc8
to receive the first batch of power management updates for v4.12-rc1.
This time the majority of changes go to the cpufreq subsystem (and
to the intel_pstate driver in particular) and there are some updates
in the generic power domains framework, cpuidle, tools and a couple
of other places.
One thing worth mentioning is that the intel_pstate's sysfs interface
has been reworked to be more consistent with the general expectations
of the cpufreq core and less confusing, hopefully for the better.
Also, we have a new cpufreq driver for Tegra186 and new hardware
support in intel_pstata and the Mediatek cpufreq driver.
Apart from that, the AnalyzeSuspend utility for system suspend
profiling gets a companion called AnalyzeBoot for the analogous
profiling of system boot and they both go into one place under
tools/power/pm-graph/.
The rest is mostly fixes, cleanups and code reorganization.
Specifics:
- Rework the intel_pstate driver's sysfs interface to make it
more straightforward and more intuitive (Rafael Wysocki).
- Make intel_pstate support all processors which advertise HWP
(hardware-managed P-states) to the kernel in all operation modes
and make it use the load-based P-state selection algorithm on a
wider range of systems in the active mode (Rafael Wysocki).
- Add cpufreq driver for Tegra186 (Mikko Perttunen).
- Add support for Gemini Lake SoCs to intel_pstate (David Box).
- Add support for MT8176 and MT817x to the Mediatek cpufreq driver
and clean up that driver a bit (Daniel Kurtz).
- Clean up intel_pstate and optimize it slightly (Rafael Wysocki).
- Update the schedutil cpufreq governor, mostly to fix a couple of
issues with it related to specific workloads, and rework its sysfs
tunable and initialization a bit (Rafael Wysocki, Viresh Kumar).
- Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers
(Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar,
YuanTian Tang).
- Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert
Uytterhoeven).
- Add support for "always on" power domains to the genpd (generic
power domains) framework and clean up that code somewhat (Ulf
Hansson, Lina Iyer, Viresh Kumar).
- Fix minor issues in the powernv cpuidle driver and clean it up
(Anton Blanchard, Gautham Shenoy).
- Move the AnalyzeSuspend utility under tools/power/pm-graph/ and
add an analogous boot-profiling utility called AnalyzeBoot to it
(Todd Brandt).
- Add rk3328 support to the rockchip-io AVS (Adaptive Voltage
Scaling) driver (David Wu).
- Fix minor issues in the cpuidle core, the intel_pstate_tracer
utility, the devfreq framework and the PM core documentation
(Chanwoo Choi, Doug Smythies, Johan Hovold, Marcin Nowakowski).
Thanks!
