Merge tag 'timers-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource - Use designated initializers for sh_mtu2, sh_cmt, and sh_tmu, and drop the unused initializer in the platform_device_id table for sh_mtu2 (Uwe Kleine-König) - Remove redundant dev_err()/dev_err_probe() messages when devm_request_*_irq() fails, as the helper already logs an error message (Pan Chuang) - Fix a boot hang on Allwinner D1 when a forced minimum delta is used with the sun4i timer (Felix Yan) - Fix an IRQ leak in the cpuhp_setup_state() error path by freeing the IRQ on failure in the NXP PIT driver (WenTao Liang) - Fix incorrect unmapping of shared MMIO between the clocksource and clockevent drivers.

dca82e209e5ced94b9e53c004a935bc44162073d - PM: sleep: Allow disabling DPM watchdog by default

Mon, 20 Jul 2026 05:08:21 +0200

PM: sleep: Allow disabling DPM watchdog by defaultIntroduce the "dpm_watchdog_enabled" module parameter to allow the DPMwatchdog to be enabled or disabled at boot time and runtime.Additionally, introduce the CONFIG_DPM_WATCHDOG_ENABLED Kconfig optionto set the default value of the module parameter at compile time.The primary motivation for this configurability resolves around AndroidGKI (Generic Kernel Image). We want to enable CONFIG_DPM_WATCHDOG inthe GKI so the feature is available. However, because the GKI is sharedacross many different devices, we don't want to inadvertently affectdevices that are unaware of this feature. This provides a way tocompile it in, but keep it disabled by default for those devices via thekernel command line or module parameters.To maintain backward compatibility, CONFIG_DPM_WATCHDOG_ENABLED relieson `default y`. Previously, the DPM watchdog was always active ifCONFIG_DPM_WATCHDOG was set. Defaulting this new option to 'y' ensuresthat the behavior remains unchanged for existing users and defconfigswhen they upgrade.Signed-off-by: Tzung-Bi Shih Link: https://patch.msgid.link/20260720030821.2780257-3-tzungbi@kernel.orgSigned-off-by: Rafael J.

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) -
