Subject: [GIT PULL] Power management updates for v5.18-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.18-rc1
with top-most commit ec3d8b8365e9865b43099e943ec5f0bc12f28f96
Merge branch 'pm-tools'
on top of commit 7e57714cd0ad2d5bb90e50b5096a0e671dec1ef3
Linux 5.17-rc6
to receive power management updates for 5.18-rc1.
These are mostly fixes and cleanups all over the code and a new
piece of documentation for Intel uncore frequency scaling.
Functionality-wise, the intel_idle driver will support Sapphire
Rapids Xeons natively now (with some extra facilities for controlling
C-states more precisely on those systems), virtual guests will take
the ACPI S4 hardware signature into account by default, the
intel_pstate driver will take the defualt EPP value from the
firmware, cpupower utility will support the AMD P-state driver added
in the previous cycle and there is a new tracer utility for that
driver.
Specifics:
- Allow device_pm_check_callbacks() to be called from interrupt
context without issues (Dmitry Baryshkov).
- Modify devm_pm_runtime_enable() to automatically handle
pm_runtime_dont_use_autosuspend() at driver exit time (Douglas
Anderson).
- Make the schedutil cpufreq governor use to_gov_attr_set() instead
of open coding it (Kevin Hao).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
cpufreq longhaul driver (Rafael Wysocki).
- Unify show() and store() naming in cpufreq and make it use
__ATTR_XX (Lianjie Zhang).
- Make the intel_pstate driver use the EPP value set by the firmware
by default (Srinivas Pandruvada).
- Re-order the init checks in the powernow-k8 cpufreq driver (Mario
Limonciello).
- Make the ACPI processor idle driver check for architectural
support for LPI to avoid using it on x86 by mistake (Mario
Limonciello).
- Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
Bityutskiy).
- Add 'preferred_cstates' module argument to the intel_idle driver
to work around C1 and C1E handling issue on Sapphire Rapids (Artem
Bityutskiy).
- Add core C6 optimization on Sapphire Rapids to the intel_idle
driver (Artem Bityutskiy).
- Optimize the haltpoll cpuidle driver a bit (Li RongQing).
- Remove leftover text from intel_idle() kerneldoc comment and fix
up white space in intel_idle (Rafael Wysocki).
- Fix load_image_and_restore() error path (Ye Bin).
- Fix typos in comments in the system wakeup hadling code (Tom Rix).
- Clean up non-kernel-doc comments in hibernation code (Jiapeng
Chong).
- Fix __setup handler error handling in system-wide suspend and
hibernation core code (Randy Dunlap).
- Add device name to suspend_report_result() (Youngjin Jang).
- Make virtual guests honour ACPI S4 hardware signature by
default (David Woodhouse).
- Block power off of a parent PM domain unless child is in deepest
state (Ulf Hansson).
- Use dev_err_probe() to simplify error handling for generic PM
domains (Ahmad Fatoum).
- Fix sleep-in-atomic bug caused by genpd_debug_remove() (Shawn Guo).
- Document Intel uncore frequency scaling (Srinivas Pandruvada).
- Add DTPM hierarchy description (Daniel Lezcano).
- Change the locking scheme in DTPM (Daniel Lezcano).
- Fix dtpm_cpu cleanup at exit time and missing virtual DTPM pointer
release (Daniel Lezcano).
- Make dtpm_node_callback[] static (kernel test robot).
- Fix spelling mistake "initialze" -> "initialize" in
dtpm_create_hierarchy() (Colin Ian King).
- Add tracer tool for the amd-pstate driver (Jinzhou Su).
- Fix PC6 displaying in turbostat on some systems (Artem Bityutskiy).
- Add AMD P-State support to the cpupower utility (Huang Rui).
Thanks!
