Subject: [GIT PULL] Power management updates for v6.6-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.6-rc1
with top-most commit 422ec6fe2704593c87c14a8ef296d92f6b368c53
Merge tag 'opp-updates-6.6' of
git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm
on top of commit 706a741595047797872e669b3101429ab8d378ef
Linux 6.5-rc7
to receive power management updates for 6.6-rc1.
These rework cpuidle governors to call tick_nohz_get_sleep_length() less
often and fix one of them, rework hibernation to avoid storing pages
filled with zeros in hibernation images, switch over some cpufreq
drivers to use void remove callbacks, fix and clean up multiple
cpufreq drivers, fix the devfreq core, update the cpupower utility and
make other assorted improvements.
Specifics:
- Rework the menu and teo cpuidle governors to avoid calling
tick_nohz_get_sleep_length(), which is likely to become quite
expensive going forward, too often and improve making decisions
regarding whether or not to stop the scheduler tick in the teo
governor (Rafael Wysocki).
- Improve the performance of cpufreq_stats_create_table() in some
cases (Liao Chang).
- Fix two issues in the amd-pstate-ut cpufreq driver (Swapnil Sapkal).
- Use clamp() helper macro to improve the code readability in
cpufreq_verify_within_limits() (Liao Chang).
- Set stale CPU frequency to minimum in intel_pstate (Doug Smythies).
- Migrate cpufreq drivers for various platforms to use void remove
callback (Yangtao Li).
- Add online/offline/exit hooks for Tegra driver (Sumit Gupta).
- Explicitly include correct DT includes in cpufreq (Rob Herring).
- Frequency domain updates for qcom-hw driver (Neil Armstrong).
- Modify AMD pstate driver to return the highest_perf value (Meng Li).
- Generic cleanups for cppc, mediatek and powernow driver (Liao Chang,
Konrad Dybcio).
- Add more platforms to cpufreq-arm driver's blocklist (AngeloGioacchino
Del Regno and Konrad Dybcio).
- brcmstb-avs-cpufreq: Fix -Warray-bounds bug (Gustavo A. R. Silva).
- Add device PM helpers to allow a device to remain powered-on during
system-wide transitions (Ulf Hansson).
- Rework hibernation memory snapshotting to avoid storing pages filled
with zeros in hibernation image files (Brian Geffon).
- Add check to make sure that CPU latency QoS constraints do not use
negative values (Clive Lin).
- Optimize rp->domains memory allocation in the Intel RAPL power
capping driver (xiongxin).
- Remove recursion while parsing zones in the arm_scmi power capping
driver (Cristian Marussi).
- Fix memory leak in devfreq_dev_release() (Boris Brezillon).
- Rewrite devfreq_monitor_start() kerneldoc comment (Manivannan
Sadhasivam).
- Explicitly include correct DT includes in devfreq (Rob Herring).
- Remove unused pm_runtime_update_max_time_suspended() extern
declaration (YueHaibing).
- Add turbo-boost support to cpupower (Wyes Karny).
- Add support for amd_pstate mode change to cpupower (Wyes Karny).
- Fix 'cpupower idle_set' command to accept only numeric values of
arguments (Likhitha Korrapati).
- Clean up OPP code and add new frequency related APIs to it (Viresh
Kumar, Manivannan Sadhasivam).
- Convert ti cpufreq/opp bindings to json schema (Nishanth Menon).
Thanks!
