Subject: [GIT PULL] Power management updates for v6.14-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-6.14-rc1
with top-most commit 1c91c99075db4e31fb5cf0838ce59e80ecd51eab
Merge branch 'pm-tools'
on top of commit 3744b08449c27bfa085aa218c4830f3996a51626
Merge branch 'pm-cpufreq'
to receive power management updates for 6.14-rc1.
The majority of changes here are cpufreq updates which are dominated by
amd-pstate driver changes, like in the previous cycle. Moreover, changes
related to amd-pstate are also the majority of cpupower utility updates.
Included are some pieces of new hardware support, like the addition of
Clearwater Forest processors support to intel_idle, new cpufreq driver
for Airoha SoCs, and Apple cpufreq driver extensions to support more
SoCs. The intel_pstate driver is also extended to be able to support
new platforms by using ACPI CPPC to compute scaling factors between HWP
performance states and frequency.
The rest is mostly fixes and cleanups in assorted pieces of power
management code.
Specifics:
- Use str_enable_disable()-like helpers in cpufreq (Krzysztof
Kozlowski).
- Extend the Apple cpufreq driver to support more SoCs (Hector Martin,
Nick Chan).
- Add new cpufreq driver for Airoha SoCs (Christian Marangi).
- Fix using cpufreq-dt as module (Andreas Kemnade).
- Minor fixes for Sparc, SCMI, and Qcom cpufreq drivers (Ethan Carter
Edwards, Sibi Sankar, Manivannan Sadhasivam).
- Fix the maximum supported frequency computation in the ACPI cpufreq
driver to avoid relying on unfounded assumptions (Gautham Shenoy).
- Fix an amd-pstate driver regression with preferred core rankings not
being used (Mario Limonciello).
- Fix a precision issue with frequency calculation in the amd-pstate
driver (Naresh Solanki).
- Add ftrace event to the amd-pstate driver for active mode (Mario
Limonciello).
- Set default EPP policy on Ryzen processors in amd-pstate (Mario
Limonciello).
- Clean up the amd-pstate cpufreq driver and optimize it to increase
code reuse (Mario Limonciello, Dhananjay Ugwekar).
- Use CPPC to get scaling factors between HWP performance levels and
frequency in the intel_pstate driver and make it stop using a built
-in scaling factor for Arrow Lake processors (Rafael Wysocki).
- Make intel_pstate initialize epp_policy to CPUFREQ_POLICY_UNKNOWN for
consistency with CPU offline (Christian Loehle).
- Fix superfluous updates caused by need_freq_update in the schedutil
cpufreq governor (Sultan Alsawaf).
- Allow configuring the system suspend-resume (DPM) watchdog to warn
earlier than panic (Douglas Anderson).
- Implement devm_device_init_wakeup() helper and introduce a device-
managed variant of dev_pm_set_wake_irq() (Joe Hattori, Peng Fan).
- Remove direct inclusions of 'pm_wakeup.h' which should be only
included via 'device.h' (Wolfram Sang).
- Clean up two comments in the core system-wide PM code (Rafael
Wysocki, Randy Dunlap).
- Add Clearwater Forest processor support to the intel_idle cpuidle
driver (Artem Bityutskiy).
- Clean up the Exynos devfreq driver and devfreq core (Markus Elfring,
Jeongjun Park).
- Minor cleanups and fixes for OPP (Dan Carpenter, Neil Armstrong, Joe
Hattori).
- Implement dev_pm_opp_get_bw() (Neil Armstrong).
- Expose OPP reference counting helpers for Rust (Viresh Kumar).
- Fix TSC MHz calculation in cpupower (He Rongguang).
- Add install and uninstall options to bindings Makefile and add header
changes for cpufreq.h to SWIG bindings in cpupower (John B. Wyatt IV).
- Add missing residency header changes in cpuidle.h to SWIG bindings in
cpupower (John B. Wyatt IV).
- Add output files to .gitignore and clean them up in "make clean" in
selftests/cpufreq (Li Zhijian).
- Fix cross-compilation in cpupower Makefile (Peng Fan).
- Revise the is_valid flag handling for idle_monitor in the cpupower
utility (wangfushuai).
- Extend and clean up AMD processors support in cpupower (Mario
Limonciello).
Thanks!
