Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.2-rc1
with top-most commit ed6a00471dd444af085164f987e3d5e8145da35a
Merge branches 'pm-devfreq' and 'pm-tools'
on top of commit 76dcd734eca23168cb008912c0f69ff408905235
Linux 6.1-rc8
to receive power management updates for 6.2-rc1.
These include two new drivers (cpufreq driver for Apple SoC CPU
P-states and the SCMI Powercap based power capping driver), other new
hardware support and driver extensions (Qualcomm cpufreq driver and
its DT bindings, TI cpufreq driver, intel_pstate, intel-uncore-freq),
a bunch of fixes and cleanups all over and a cpupower utility update
including new features related to RAPL support.
Specifics:
- Fix nasty and hard to debug race condition introduced by mistake
in the runtime PM core code and clean up that code somewhat on
top of the fix (Rafael Wysocki).
- Generalize of_perf_domain_get_sharing_cpumask phandle format (Hector
Martin).
- Add new cpufreq driver for Apple SoC CPU P-states (Hector Martin).
- Update Qualcomm cpufreq driver, including:
* CPU clock provider support,
* Generic cleanups or reorganization.
* Potential memleak fix.
* Fix of the return value of cpufreq_driver->get().
(Manivannan Sadhasivam, Chen Hui).
- Update Qualcomm cpufreq driver's DT bindings, including:
* Support for CPU clock provider.
* Missing cache-related properties fixes.
* Support for QDU1000/QRU1000.
(Manivannan Sadhasivam, Rob Herring, Melody Olvera).
- Add support for ti,am625 SoC and enable build of ti-cpufreq for
ARCH_K3 (Dave Gerlach, and Vibhore Vardhan).
- Use flexible array to simplify memory allocation in the tegra186
cpufreq driver (Christophe JAILLET).
- Convert cpufreq statistics code to use sysfs_emit_at() (ye xingchen).
- Allow intel_pstate to use no-HWP mode on Sapphire Rapids (Giovanni
Gherdovich).
- Add missing pci_dev_put() to the amd_freq_sensitivity cpufreq driver
(Xiongfeng Wang).
- Initialize the kobj_unregister completion before calling
kobject_init_and_add() in the cpufreq core code (Yongqiang Liu).
- Defer setting boost MSRs in the ACPI cpufreq driver (Stuart Hayes,
Nathan Chancellor).
- Make intel_pstate accept initial EPP value of 0x80 (Srinivas
Pandruvada).
- Make read-only array sys_clk_src in the SPEAr cpufreq driver static
(Colin Ian King).
- Make array speeds in the longhaul cpufreq driver static (Colin Ian
King).
- Use str_enabled_disabled() helper in the ACPI cpufreq driver (Andy
Shevchenko).
- Drop a reference to CVS from cpufreq documentation (Conghui Wang).
- Improve kernel messages printed by the PSCI cpuidle driver (Ulf
Hansson).
- Make the DT cpuidle driver return the correct number of parsed idle
states, clean it up and clarify a comment in it (Ulf Hansson).
- Modify the tasks freezing code to avoid using pr_cont() and refine an
error message printed by it (Rafael Wysocki).
- Make the hibernation core code complain about memory map mismatches
during resume to help diagnostics (Xueqin Luo).
- Fix mistake in a kerneldoc comment in the hibernation code (xiongxin).
- Reverse the order of performance and enabling operations in the
generic power domains code (Abel Vesa).
- Power off[on] domains in hibernate .freeze[thaw]_noirq hook of in the
generic power domains code (Abel Vesa).
- Consolidate genpd_restore_noirq() and genpd_resume_noirq() (Shawn
Guo).
- Pass generic PM noirq hooks to genpd_finish_suspend() (Shawn Guo).
- Drop generic power domain status manipulation during hibernate
restore (Shawn Guo).
- Fix compiler warnings with make W=1 in the idle_inject power capping
driver (Srinivas Pandruvada).
- Use kstrtobool() instead of strtobool() in the power capping sysfs
interface (Christophe JAILLET).
- Add SCMI Powercap based power capping driver (Cristian Marussi).
- Add Emerald Rapids support to the intel-uncore-freq driver (Artem
Bityutskiy).
- Repair slips in kernel-doc comments in the generic notifier code
(Lukas Bulwahn).
- Fix several DT issues in the OPP library reorganize code around
opp-microvolt-<named> DT property (Viresh Kumar).
- Allow any of opp-microvolt, opp-microamp, or opp-microwatt properties
to be present without the others present (James Calligeros).
- Fix clock-latency-ns property in DT example (Serge Semin).
- Add a private governor_data for devfreq governors (Kant Fan).
- Reorganize devfreq code to use device_match_of_node() and
devm_platform_get_and_ioremap_resource() instead of open coding
them (ye xingchen, Minghao Chi).
- Make cpupower choose base_cpu to display default cpupower details
instead of picking CPU 0 (Saket Kumar Bhaskar).
- Add Georgian translation to cpupower documentation (Zurab
Kargareteli).
- Introduce powercap intel-rapl library, powercap-info command, and
RAPL monitor into cpupower (Thomas Renninger).
Thanks!
