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) - Fix a memory leak in rapl_add_package_cpuslocked() in the intel_rapl power capping driver and use sysfs_emit() in cpumask_show() in that driver (Sumeet Pawnikar, Yury Norov) - Fix ValueError when parsing incomplete device properties in the pm-graph utility (Gongwei Li)" * tag 'pm-7.2-rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/rafael/linux-pm: (40 commits) PM: dpm_watchdog: Add sysctl interface for DPM watchdog timeouts PM: QoS: Fix misc device registration unwind cpufreq: Use policy->min/max init as QoS request cpufreq: Remove driver default policy->min/max init cpufreq: Set default policy->min/max values for all drivers cpufreq: Extract cpufreq_policy_init_qos() function cpufreq: Documentation: fix conservative governor freq_step description cpufreq: ti: Add EPROBE_DEFER for K3 SoCs cpufreq: qcom: Add cpufreq scaling support for Qualcomm Shikra SoC dt-bindings: cpufreq: Document Qualcomm Shikra SoC EPSS powercap: intel_rapl: Use sysfs_emit() in cpumask_show() cpufreq: governor: Fix stale prev_cpu_nice spike when enabling ignore_nice_load cpufreq: governor: Fix data races on per-CPU idle/nice baselines PM: hibernate: Use flexible array for CRC uncompressed buffers powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked() PM: hibernate: make LZ4 available for hibernation compression PM: sleep: Use complete() in device_pm_sleep_init() opp: rust: mark OPP methods as inline cpufreq: intel_pstate: Improve warning message on HWP-disabled hybrid CPUs cpufreq: elanfreq: Drop support for AMD Elan SC4* ...

tools/power/x86/intel-speed-select: Harden daemon pidfile open

2026-06-02T17:39:45+00:00

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.

tools/power turbostat: pmt: Improve sscanf() hygiene

2026-05-24T14:26:22+00:00

Explicitly check sscanf() return values for number of matches, and handle EOF (-1). Defensive programming -- not an issue seen by users. Fixes: 4265a86582ea ("tools/power turbostat: Add PMT directory iterator helper") Assisted-by: Claude: Claude Sonnet 4.6 Signed-off-by: Len Brown

tools/power turbostat: Cleanup: bool force_load

2026-05-24T14:26:22+00:00

It is confusing to increment what is effectively a boolean value. Define force_load as boolean, and access it accordingly. Assisted-by: Claude: Claude Sonnet 4.6 Signed-off-by: Len Brown

tools/power turbostat: Fix typo: MHz, not Mhz

2026-05-24T14:26:22+00:00

tools/power turbostat: Cleanup: consistently use warn/err, not perror

No functional change, unless you count the uniform return value of -1 on calloc failure. Assisted-by: Claude: Claude Sonnet 4.6 Signed-off-by: Len Brown
