[GIT PULL] ACPI and power management updates for v3.11-rc1
From: Rafael J. Wysocki
Date: Mon Jul 01 2013 - 10:34:19 EST
Hi Linus,
Please pull from the git repository at
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm+acpi-3.11-rc1
to receive ACPI and power management updates for v3.11 with top-most commit
2c843bd92ec276ecb68504b3b5ffa7066183f032
Merge branch 'pm-cpufreq'
on top of commit 45e00374db944b1c12987b501bcaa279b3e36d93
Merge branch 'pm-fixes'
This time the total number of ACPI commits is slightly greater than the
number of cpufreq commits, but Viresh Kumar (who works on cpufreq) remains
the most active patch submitter.
To me, the most significant change is the addition of offline/online
device operations to the driver core (with the Greg's blessing) and the
related modifications of the ACPI core hotplug code. Next are the
freezer updates from Colin Cross that should make the freezing of
tasks a bit less heavy weight.
We also have a couple of regression fixes, a number of fixes for issues that
have not been identified as regressions, two new drivers and a bunch of
cleanups all over.
Highlights:
1) Hotplug changes to support graceful hot-removal failures.
It sometimes is necessary to fail device hot-removal operations
gracefully if they cannot be carried out completely. For example,
if memory from a memory module being hot-removed has been
allocated for the kernel's own use and cannot be moved elsewhere,
it's desirable to fail the hot-removal operation in a graceful way
rather than to crash the kernel, but currenty a success or a
kernel crash are the only possible outcomes of an attempted memory
hot-removal. Needless to say, that is not a very attractive
alternative and it had to be addressed.
However, in order to make it work for memory, I first had to make
it work for CPUs and for this purpose I needed to modify the ACPI
processor driver. It's been split into two parts, a resident one
handling the low-level initialization/cleanup and a modular one
playing the actual driver's role (but it binds to the CPU system
device objects rather than to the ACPI device objects representing
processors). That's been sort of like a live brain surgery on a
patient who's riding a bike.
So this is a little scary, but since we found and fixed a couple
of regressions it caused to happen during the early linux-next
testing (a month ago), nobody has complained.
As a bonus we remove some duplicated ACPI hotplug code, because
the ACPI-based CPU hotplug is now going to use the common ACPI
hotplug code.
2) Lighter weight freezing of tasks.
These changes from Colin Cross and Mandeep Singh Baines are
targeted at making the freezing of tasks a bit less heavy weight
operation. They reduce the number of tasks woken up every time
during the freezing, by using the observation that the freezer
simply doesn't need to wake up some of them and wait for them
all to call refrigerator(). The time needed for the freezer to
decide to report a failure is reduced too.
Also reintroduced is the check causing a lockdep warining to
trigger when try_to_freeze() is called with locks held (which is
generally unsafe and shouldn't happen).
3) cpufreq updates
First off, a commit from Srivatsa S Bhat fixes a resume regression
introduced during the 3.10 cycle causing some cpufreq sysfs
attributes to return wrong values to user space after resume. The
fix is kind of fresh, but also it's pretty obvious once Srivatsa
has identified the root cause.
Second, we have a new freqdomain_cpus sysfs attribute for the
acpi-cpufreq driver to provide information previously available
via related_cpus. From Lan Tianyu.
Finally, we fix a number of issues, mostly related to the
CPUFREQ_POSTCHANGE notifier and cpufreq Kconfig options and clean
up some code. The majority of changes from Viresh Kumar with bits
from Jacob Shin, Heiko StÃbner, Xiaoguang Chen, Ezequiel Garcia,
Arnd Bergmann, and Tang Yuantian.
4) ACPICA update
A usual bunch of updates from the ACPICA upstream.
During the 3.4 cycle we introduced support for ACPI 5 extended
sleep registers, but they are only supposed to be used if the
HW-reduced mode bit is set in the FADT flags and the code
attempted to use them without checking that bit. That caused
suspend/resume regressions to happen on some systems. Fix from
Lv Zheng causes those registers to be used only if the
HW-reduced mode bit is set.
Apart from this some other ACPICA bugs are fixed and code
cleanups are made by Bob Moore, Tomasz Nowicki, Lv Zheng,
Chao Guan, and Zhang Rui.
5) cpuidle updates
New driver for Xilinx Zynq processors is added by Michal Simek.
Multidriver support simplification, addition of some missing
kerneldoc comments and Kconfig-related fixes come from Daniel Lezcano.
6) ACPI power management updates
Changes to make suspend/resume work correctly in Xen guests from
Konrad Rzeszutek Wilk, sparse warning fix from Fengguang Wu
and cleanups and fixes of the ACPI device power state selection
routine.
7) ACPI documentation updates
Some previously missing pieces of ACPI documentation are added
by Lv Zheng and Aaron Lu (hopefully, that will help people to
uderstand how the ACPI subsystem works) and one outdated doc is
updated by Hanjun Guo.
8) Assorted ACPI updates
We finally nailed down the IA-64 issue that was the reason for
reverting commit 9f29ab1 (ACPI / scan: do not match drivers
against objects having scan handlers), so we can fix it and
move the ACPI scan handler check added to the ACPI video driver
back to the core.
A mechanism for adding CMOS RTC address space handlers is
introduced by Lan Tianyu to allow some EC-related breakage to be
fixed on some systems.
A spec-compliant implementation of acpi_os_get_timer() is added
by Mika Westerberg.
The evaluation of _STA is added to do_acpi_find_child() to avoid
situations in which a pointer to a disabled device object is
returned instead of an enabled one with the same _ADR value.
From Jeff Wu.
Intel BayTrail PCH (Platform Controller Hub) support is added to
the ACPI driver for Intel Low-Power Subsystems (LPSS) and that
driver is modified to work around a couple of known BIOS issues.
Changes from Mika Westerberg and Heikki Krogerus.
The EC driver is fixed by Vasiliy Kulikov to use get_user() and
put_user() instead of dereferencing user space pointers blindly.
Code cleanups are made by Bjorn Helgaas, Nicholas Mazzuca and
Toshi Kani.
9) Assorted power management updates
The "runtime idle" helper routine is changed to take the return
values of the callbacks executed by it into account and to call
rpm_suspend() if they return 0, which allows us to reduce the
overall code bloat a bit (by dropping some code that's not
necessary any more after that modification).
The runtime PM documentation is updated by Alan Stern (to reflect
the "runtime idle" behavior change).
New trace points for PM QoS are added by Sahara
(<keun-o.park@xxxxxxxxxxxxx>).
PM QoS documentation is updated by Lan Tianyu.
Code cleanups are made and minor issues are addressed by
Bernie Thompson, Bjorn Helgaas, Julius Werner, and Shuah Khan.
10) devfreq updates
New driver for the Exynos5-bus device from Abhilash Kesavan.
Minor cleanups, fixes and MAINTAINERS update from MyungJoo Ham,
Abhilash Kesavan, Paul Bolle, Rajagopal Venkat, and Wei Yongjun.
11) OMAP power management updates
Adaptive Voltage Scaling (AVS) SmartReflex voltage control driver
updates from Andrii Tseglytskyi and Nishanth Menon.
