Subject: [GIT PULL] Power management updates for v6.7-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.7-rc1
with top-most commit bf224871c27a7c7e2146d667176977ffe3752750
Merge branches 'pm-sleep', 'powercap' and 'pm-tools'
on top of commit 05d3ef8bba77c1b5f98d941d8b2d4aeab8118ef1
Linux 6.6-rc7
to receive power management updates for 6.7-rc1.
These add new hardware support (new Qualcomm SoC versions in cpufreq,
RK3568/RK3588 in devfreq), extend the OPP (operating performance points)
framework, improve cpufreq governors, fix issues and clean up code (most
of the changes are in cpufreq and devfreq).
Specifics:
- Add support for several Qualcomm SoC versions and other similar
changes (Christian Marangi, Dmitry Baryshkov, Luca Weiss, Neil
Armstrong, Richard Acayan, Robert Marko, Rohit Agarwal, Stephan
Gerhold and Varadarajan Narayanan).
- Clean up the tegra cpufreq driver (Sumit Gupta).
- Use of_property_read_reg() to parse "reg" in pmac32 driver (Rob
Herring).
- Add support for TI's am62p5 Soc (Bryan Brattlof).
- Make ARM_BRCMSTB_AVS_CPUFREQ depends on !ARM_SCMI_CPUFREQ (Florian
Fainelli).
- Update Kconfig to mention i.MX7 as well (Alexander Stein).
- Revise global turbo disable check in intel_pstate (Srinivas
Pandruvada).
- Carry out initialization of sg_cpu in the schedutil cpufreq governor
in one loop (Liao Chang).
- Simplify the condition for storing 'down_threshold' in the
conservative cpufreq governor (Liao Chang).
- Use fine-grained mutex in the userspace cpufreq governor (Liao
Chang).
- Move is_managed indicator in the userspace cpufreq governor into a
per-policy structure (Liao Chang).
- Rebuild sched-domains when removing cpufreq driver (Pierre Gondois).
- Fix buffer overflow detection in trans_stats() (Christian Marangi).
- Switch to dev_pm_opp_find_freq_(ceil/floor)_indexed() APIs to support
specific devices like UFS which handle multiple clocks through OPP
(Operating Performance Point) framework (Manivannan Sadhasivam).
- Add perf support to the Rockchip DFI (DDR Monitor Module) devfreq-
event driver:
* Generalize rockchip-dfi.c to support new RK3568/RK3588 using
different DDR type (Sascha Hauer).
* Convert DT binding document format to yaml (Sascha Hauer).
* Add perf support for DFI (a unit suitable for measuring DDR
utilization) to rockchip-dfi.c to extend DFI usage (Sascha Hauer).
- Add locking to the OPP handling code in the Mediatek CCI devfreq
driver, because the voltage of shared OPP might be changed by
multiple drivers (Mark Tseng, Dan Carpenter).
- Use device_get_match_data() in the Samsung Exynos PPMU devfreq-event
driver (Rob Herring).
- Extend support for the opp-level beyond required-opps (Ulf Hansson).
- Add dev_pm_opp_find_level_floor() (Krishna chaitanya chundru).
- dt-bindings: Allow opp-peak-kBpsfor kryo CPUs, support Qualcomm Krait
SoCs and document named opp-microvolt property (Bjorn Andersson,
Dmitry Baryshkov and Christian Marangi).
- Fix -Wunsequenced warning _of_add_opp_table_v1() (Nathan Chancellor).
- General cleanup of OPP code (Viresh Kumar).
- Use __get_safe_page() rather than touching the list in hibernation
snapshot code (Brian Geffon).
- Fix symbol export for _SIMPLE_ variants of _PM_OPS() (Raag Jadav).
- Clean up sync_read handling in snapshot_write_next() (Brian Geffon).
- Fix kerneldoc comments for swsusp_check() and swsusp_close() to
better match code (Christoph Hellwig).
- Downgrade BIOS locked limits pr_warn() in the Intel RAPL power
capping driver to pr_debug() (Ville Syrjälä).
- Change the minimum python version for the intel_pstate_tracer utility
from 2.7 to 3.6 (Doug Smythies).
Thanks!
