Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.18-rc1
to receive ACPI and power management updates for v3.18-rc1 with
top-most commit 9f1a053296953c69d7f23511db9441290cb89e2c
Merge branch 'pm-clk'
on top of commit bfe01a5ba2490f299e1d2d5508cbbbadd897bbe9
Linux 3.17
Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help
with this work.
Second is an update of the generic PM domains code that has been
in need of some care for quite a while. Unused code is being
removed, DT support is being added and domains are now going to
be attached to devices in bus type code in analogy with the ACPI
PM domain. The majority of work here was done by Ulf Hansson
who also has been the most active developer this time.
Apart from this we have a traditional ACPICA update, this time
to upstream version 20140828 and a few ACPI wakeup interrupts
handling patches on top of the general rework mentioned above.
There also are several cpufreq commits including renaming the
cpufreq-cpu0 driver to cpufreq-dt, as this is what implements
generic DT-based cpufreq support, and a new DT-based idle states
infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI
support for Apple machines is improved, a few bugs are fixed
and a few cleanups are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this
time with 32 non-merge commits, second is cpufreq (15 commits) and
the 3rd place goes to the wakeup interrupts handling rework (13
commits).
Specifics:
- Rework the handling of wakeup IRQs by the IRQ core such that
all of them will be switched over to "wakeup" mode in
suspend_device_irqs() and in that mode the first interrupt
will abort system suspend in progress or wake up the system
if already in suspend-to-idle (or equivalent) without executing
any interrupt handlers. Among other things that eliminates the
wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
flag with interrupts which don't really need it and should not
use it (Thomas Gleixner and Rafael J Wysocki).
- Switch over ACPI to handling wakeup interrupts with the help
of the new mechanism introduced by the above IRQ core rework
(Rafael J Wysocki).
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during
enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in
the METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot
(or after resume from system suspend) and rework the ACPI Smart
Battery Subsystem (SBS) driver to work correctly with Apple
platforms (Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
code, adding support for 133MHz I2C source clock on Intel Baytrail
to it and making it avoid using UART RTS override with Auto Flow
Control (Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
Sudip Mukherjee, Yijing Wang, and Zhang Rui).
- cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
Rasmus Villemoes).
- cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
change among other things), ppc-corenet, powernv (Viresh Kumar,
Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
- cpuidle support for DT-based idle states infrastructure, new
ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
Rasmus Villemoes).
- ARM big.LITTLE cpuidle driver updates: support for DT-based
initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
Kevin Hilman).
- Rework of the test_suspend kernel command line argument and
a new trace event for console resume (Srinivas Pandruvada,
Todd E Brandt).
- Second attempt to optimize swsusp_free() (hibernation core) to
make it avoid going through all PFNs which may be way too slow on
some systems (Joerg Roedel).
- devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
- rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
entry update in MAINTAINERS (Heiko StÃbner, Kevin Hilman).
- PM core fix related to clock management (Geert Uytterhoeven).
- PM core's sysfs code cleanup (Johannes Berg).
Thanks!
