Date: Sat Jan 20 2018 - 21:21:09 EST
Hi Linus,
This goes early, because I'm attending the LCA next week and I may be
sparsely available and generally time-constrained during the next
several days.
In case you decide to open the 4.16 merge window any time soon, please
pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.16-rc1
with top-most commit ee43730d65155c5b3c3d0531f11daf59f8f42a73
Merge branches 'pm-opp', 'pm-devfreq', 'pm-avs' and 'pm-tools'
on top of commit a8750ddca918032d6349adbf9a4b6555e7db20da
Linux 4.15-rc8
to receive power management updates for 4.16-rc1.
This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend
and hibernation, plus some driver changes depending on them and
fixes for issues in that area which have become quite apparent
recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on
Surface Pro3.
On the cpufreq front we have fixes and cleanups in the core, some
new hardware support, driver updates and the removal of some unused
code from the CPU cooling thermal driver.
Apart from this, the Operating Performance Points (OPP) framework
is prepared to be used with power domains in the future and there
is a usual bunch of assorted fixes and cleanups.
Specifics:
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver
PM flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of
genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the
ACPI core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal
and clean up the governor management code in the cpufreq core
(Rafael Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id
from the PSCI driver and drop dependency on arm_big_little from
the SCPI cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,
Kyungsik Lee).
- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
Sergey Senozhatsky, gaurav jindal).
- Make it easier to disable PM via Kconfig (Mark Brown).
- Clean up the cpupower and intel_pstate_tracer utilities (Doug
Smythies, Laura Abbott).
Thanks!
