Pull power management updates from Rafael Wysocki:
"Over a half of the changes here are cpufreq updates that include core
modifications, fixes of the old-style governors, new hardware support
in drivers, assorded driver fixes and cleanups, and the removal of one
driver (AMD Elan SC4*).
Apart from that, the intel_idle driver will now be able to avoid
exposing redundant C-states if PC6 is disabled and there are new
sysctl knobs for device suspend/resume watchdog timeouts, hibernation
gets built-in LZ4 support for image compression and there is the usual
collection of assorted fixes and cleanups.
Specifics:
- Fix a race between cpufreq suspend and CPU hotplug during system
shutdown (Tianxiang Chen)
- Avoid redundant target() calls for unchanged limits and fix a typo
in a comment in the cpufreq core (Viresh Kumar)
- Fix concurrency issues related to sysfs attributes access that
affect cpufreq governors using the common governor code (Zhongqiu
Han)
- Simplify frequency limit handling in the conservative cpufreq
governor (Lifeng Zheng)
- Fix descriptions of the conservative governor freq_step tunable and
the ondemand governor sampling_down_factor tunable in the cpufreq
documentation (Pengjie Zhang)
- Fix use-after-free and double free during _OSC evaluation in the
PCC cpufreq driver (Yuho Choi)
- Rework the handling of policy min and max frequency values in the
cpufreq core to allow drivers to specify special initial values for
the scaling_min_freq and scaling_max_freq sysfs attributes (Pierre
Gondois)
- Add cpufreq scaling support for Qualcomm Shikra SoC (Taniya Das,
Imran Shaik).
- Improve the warning message on HWP-disabled hybrid processors
printed by the intel_pstate driver and sync policy->cur during CPU
offline in it (Yohei Kojima, Fushuai Wang)
- Drop cpufreq support for AMD Elan SC4* (Sean Young)
- Minor fixes for cpufreq drivers (Krzysztof Kozlowski, Akashdeep
Kaur, Hans Zhang, Guangshuo Li, Xueqin Luo)
- Clean up dead dependencies on X86 in the cpufreq Kconfig (Julian
Braha)
- Allow the intel_idle driver to avoid exposing C-states that are
redundant when PC6 is disabled (Artem Bityutskiy)
- Fix memory leak and a potential race in the OPP core (Abdun Nihaal,
Di Shen)
- Mark Rust OPP methods as inline (Nicolás Antinori)
- Fix misc device registration failure path in the PM QoS core (Yuho
Choi)
- Add sysctl interface for DPM watchdog timeouts (Tzung-Bi Shih)
- Use complete() instead of complete_all() in device_pm_sleep_init()
to avoid a false-positive warning from lockdep_assert_RT_in_threaded_ctx()
when CONFIG_PROVE_RAW_LOCK_NESTING is enabled (Jiakai Xu)
- Use a flexible array for CRC uncompressed buffers during
hibernation image saving (Rosen Penev)
- Make the LZ4 algorithm available for hibernation compression
(l1rox3)
- Move the preallocate_image() call during hibernation after the
"prepare" phase of the "freeze" transition (Matthew Leach)

intel_rapl power capping driver and use sysfs_emit() in
cpumask_show() in that driver (Sumeet Pawnikar, Yury Norov)

pm-graph utility (Gongwei Li)"

Avoid symlink-based pidfile clobbering by opening the pidfile with
O_NOFOLLOW and validating it with fstat() before locking/writing.
The daemon currently uses a fixed pidfile path under /tmp. A local
unprivileged user can pre-create a symlink at that path and cause a
root-run daemon instance to write into an attacker-chosen file.

When parsing device properties from ftrace data, the devprops() function
assumes that each line has at least three fields and that the third field
(f[2]) always contains a valid integer. However, due to incomplete or
corrupted ftrace logs, f[2] may be missing, empty, or non-existent.
This can lead to the following error:

Since v2025.11.22: Initial SoC Slider support SoC Slider is an SoC-wide power/performance policy setting. On SoC Slider systems, EPP plays a diminished role. Whitespace cleanup via: indent -npro -kr -i8 -ts8 -sob -l160 -ss -ncs -cp1 No functional changes Signed-off-by: Len Brown <len.brown@intel.com>
x86_energy_perf_policy accesses the SoC Slider via standard user/kernel APIs to the processor_thermal_soc_slider driver. Machines that support SoC Slider largely use it instead of EPP, which may continue to exist in a diminished role, or vanish entirely. Signed-off-by: Len Brown <len.brown@intel.com>
When processor_thermal_soc_slider is loaded, its slider and offset modparams are visible. Check that the driver actually registered the profile named "SoC Slider" before reading or writing these modparams. n.b. This utility allows writing the Slider and Offset modparams even if the driver policy is not "balanced". Currently the processor_thermal_soc_slider consults those modparams only in "balanced" mode.
