Tue, 10 Feb 2026 04:00:42 +0100

Merge tag 'pm-6.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pmPull power management updates from Rafael Wysocki: "By the number of commits, cpufreq is the leading party (again) and the most visible change there is the removal of the omap-cpufreq driver that has not been used for a long time (good riddance). There are also quite a few changes in the cppc_cpufreq driver, mostly related to fixing its frequency invariance engine in the case when the CPPC registers used by it are not in PCC. In addition to that, support for AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev list is updated for some platforms. The remaining cpufreq changes are assorted fixes and cleanups. Next up is cpuidle and the changes there are dominated by intel_idle driver updates, mostly related to the new command line facility allowing users to adjust the list of C-states used by the driver. There are also a few updates of cpuidle governors, including two menu governor fixes and some refinements of the teo governor, and a MAINTAINERS update adding Christian Loehle as a cpuidle reviewer. [Thanks for stepping up Christian!] The most significant update related to system suspend and hibernation is the one to stop freezing the PM runtime workqueue during system PM transitions which allows some deadlocks to be avoided. There is also a fix for possible concurrent bit field updates in the core device suspend code and a few other minor fixes. Apart from the above, several drivers are updated to discard the return value of pm_runtime_put() which is going to be converted to a void function as soon as everybody stops using its return value, PL4 support for Ice Lake is added to the Intel RAPL power capping driver, and there are assorted cleanups, documentation fixes, and some cpupower utility improvements. Specifics: - Remove the unused omap-cpufreq driver (Andreas Kemnade) - Optimize error handling code in cpufreq_boost_trigger_state() and make cpufreq_boost_trigger_state() return -EOPNOTSUPP if no policy supports boost (Lifeng Zheng) - Update cpufreq-dt-platdev list for tegra, qcom, TI (Aaron Kling, Dhruva Gole, and Konrad Dybcio) - Minor improvements to the cpufreq and cpumask rust implementation (Alexandre Courbot, Alice Ryhl, Tamir Duberstein, and Yilin Chen) - Add support for AM62L3 SoC to the ti-cpufreq driver (Dhruva Gole) - Update arch_freq_scale in the CPPC cpufreq driver's frequency invariance engine (FIE) in scheduler ticks if the related CPPC registers are not in PCC (Jie Zhan) - Assorted minor cleanups and improvements in ARM cpufreq drivers (Juan Martinez, Felix Gu, Luca Weiss, and Sergey Shtylyov) - Add generic helpers for sysfs show/store to cppc_cpufreq (Sumit Gupta) - Make the scaling_setspeed cpufreq sysfs attribute return the actual requested frequency to avoid confusion (Pengjie Zhang) - Simplify the idle CPU time granularity test in the ondemand cpufreq governor (Frederic Weisbecker) - Enable asym capacity in intel_pstate only when CPU SMT is not possible (Yaxiong Tian) - Update the description of rate_limit_us default value in cpufreq documentation (Yaxiong Tian) - Add a command line option to adjust the C-states table in the intel_idle driver, remove the 'preferred_cstates' module parameter from it, add C-states validation to it and clean it up (Artem Bityutskiy) - Make the menu cpuidle governor always check the time till the closest timer event when the scheduler tick has been stopped to prevent it from mistakenly selecting the deepest available idle state (Rafael Wysocki) - Update the teo cpuidle governor to avoid making suboptimal decisions in certain corner cases and generally improve idle state selection accuracy (Rafael Wysocki) - Remove an unlikely() annotation on the early-return condition in menu_select() that leads to branch misprediction 100% of the time on systems with only 1 idle state enabled, like ARM64 servers (Breno Leitao) - Add Christian Loehle to MAINTAINERS as a cpuidle reviewer (Christian Loehle) - Stop flagging the PM runtime workqueue as freezable to avoid system suspend and resume deadlocks in subsystems that assume asynchronous runtime PM to work during system-wide PM transitions (Rafael Wysocki) - Drop redundant NULL pointer checks before acomp_request_free() from the hibernation code handling image saving (Rafael Wysocki) - Update wakeup_sources_walk_start() to handle empty lists of wakeup sources as appropriate (Samuel Wu) - Make dev_pm_clear_wake_irq() check the power.wakeirq value under power.lock to avoid race conditions (Gui-Dong Han) - Avoid bit field races related to power.work_in_progress in the core device suspend code (Xuewen Yan) - Make several drivers discard pm_runtime_put() return value in preparation for converting that function to a void one (Rafael Wysocki) - Add PL4 support for Ice Lake to the Intel RAPL power capping driver (Daniel Tang) - Replace sprintf() with sysfs_emit() in power capping sysfs show functions (Sumeet Pawnikar) - Make dev_pm_opp_get_level() return value match the documentation after a previous update of the latter (Aleks Todorov) - Use scoped for each OF child loop in the OPP code (Krzysztof Kozlowski) - Fix a bug in an example code snippet and correct typos in the energy model management documentation (Patrick Little) - Fix miscellaneous problems in cpupower (Kaushlendra Kumar): * idle_monitor: Fix incorrect value logged after stop * Fix inverted APERF capability check * Use strcspn() to strip trailing newline * Reset errno before strtoull() * Show C0 in idle-info dump -

Merge tag 'pm-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pmPull power management updates from Rafael Wysocki: "There are quite a few interesting things here, including new hardware support, new features, some bug fixes and documentation updates. In addition, there are a usual bunch of minor fixes and cleanups all over. In the new hardware support category, there are intel_pstate and intel_rapl driver updates to support new processors, Panther Lake, Wildcat Lake, Noval Lake, and Diamond Rapids in the OOB mode, OPP and bandwidth allocation support in the tegra186 cpufreq driver, and JH7110S SOC support in dt-platdev cpufreq. The new features are the PM QoS CPU latency limit for suspend-to-idle, the netlink support for the energy model management, support for terminating system suspend via a wakeup event during the sync of file systems, configurable number of hibernation compression threads, the runtime PM auto-cleanup macros, and the "poweroff" PM event that is expected to be used during system shutdown. Bugs are mostly fixed in cpuidle governors, but there are also fixes elsewhere, like in the amd-pstate cpufreq driver. Documentation updates include, but are not limited to, a new doc on debugging shutdown hangs, cross-referencing fixes and cleanups in the intel_pstate documentation, and updates of comments in the core hibernation code. Specifics: - Introduce and document a QoS limit on CPU exit latency during wakeup from suspend-to-idle (Ulf Hansson) - Add support for building libcpupower statically (Zuo An) - Add support for sending netlink notifications to user space on energy model updates (Changwoo Mini, Peng Fan) -

Add sanity check for exit latency and target residency in the cpufreq core (Rafael Wysocki) - Use this_cpu_ptr() where possible in the teo governor (Christian Loehle) - Rework the handling of tick wakeups in the teo cpuidle governor to increase the likelihood of stopping the scheduler tick in the cases when tick wakeups can be counted as non-timer ones (Rafael Wysocki) - Fix a reverse condition in the teo cpuidle governor and drop a misguided target residency check from it (Rafael Wysocki) - Clean up multiple minor defects in the teo cpuidle governor (Rafael Wysocki) - Update header inclusion to make it follow the Include What You Use principle (Andy Shevchenko) - Enable MSR-based RAPL PMU support in the intel_rapl power capping driver and arrange for using it on the Panther Lake and Wildcat Lake processors (Kuppuswamy Sathyanarayanan) - Add support for Nova Lake and Wildcat Lake processors to the intel_rapl power capping driver (Kaushlendra Kumar, Srinivas Pandruvada) - Add OPP and bandwidth support for Tegra186 (Aaron Kling) - Optimizations for parameter array handling in the amd-pstate cpufreq driver (Mario Limonciello) - Fix for mode changes with offline CPUs in the amd-pstate cpufreq driver (Gautham Shenoy) - Preserve freq_table_sorted across suspend/hibernate in the cpufreq core (Zihuan Zhang) - Adjust energy model rules for Intel hybrid platforms in the intel_pstate cpufreq driver and improve printing of debug messages in it (Rafael Wysocki) - Replace deprecated strcpy() in cpufreq_unregister_governor() (Thorsten Blum) - Fix duplicate hyperlink target errors in the intel_pstate cpufreq driver documentation and use :ref: directive for internal linking in it (Swaraj Gaikwad, Bagas Sanjaya) - Add Diamond Rapids OOB mode support to the intel_pstate cpufreq driver (Kuppuswamy Sathyanarayanan) - Use mutex guard for driver locking in the intel_pstate driver and eliminate some code duplication from it (Rafael Wysocki) - Replace udelay() with usleep_range() in ACPI cpufreq (Kaushlendra Kumar) - Minor improvements to various cpufreq drivers (Christian Marangi, Hal Feng, Jie Zhan, Marco Crivellari, Miaoqian Lin, and Shuhao Fu) - Replace snprintf() with scnprintf() in show_trace_dev_match() (Kaushlendra Kumar) - Fix memory allocation error handling in pm_vt_switch_required() (Malaya Kumar Rout) - Introduce CALL_PM_OP() macro and use it to simplify code in generic PM operations (Kaushlendra Kumar) - Add module param to backtrace all CPUs in the device power management watchdog (Sergey Senozhatsky) - Rework message printing in swsusp_save() (Rafael Wysocki) - Make it possible to change the number of hibernation compression threads (Xueqin Luo) - Clarify that only cgroup1 freezer uses PM freezer (Tejun Heo) - Add document on debugging shutdown hangs to PM documentation and correct a mistaken configuration option in it (Mario Limonciello) - Shut down wakeup source timer before removing the wakeup source from the list (Kaushlendra Kumar, Rafael Wysocki) - Introduce new PMSG_POWEROFF event for system shutdown handling with the help of PM device callbacks (Mario Limonciello) - Make pm_test delay interruptible by wakeup events (Riwen Lu) - Clean up kernel-doc comment style usage in the core hibernation code and remove unuseful comments from it (Sunday Adelodun, Rafael Wysocki) - Add support for handling wakeup events and aborting the suspend process while it is syncing file systems (Samuel Wu, Rafael Wysocki) - Add WQ_UNBOUND to pm_wq workqueue (Marco Crivellari) - Add runtime PM wrapper macros for ACQUIRE()/ACQUIRE_ERR() and use them in the PCI core and the ACPI TAD driver (Rafael Wysocki) -
