Pull 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) -

tools/power/cpupower: Support building libcpupower statically

2025-11-05T16:56:01Z

The cpupower Makefile built and installed libcpupower as a shared library (libcpupower.so) without passing `STATIC=true`, but did not build a static version of the library even with `STATIC=true`. (Only the programs were static). Thus, out-of-tree programs using libcpupower were unable to link statically against the library without having access to intermediate object files produced during the build. This fixes that situation by ensuring that libcpupower.a is built and installed when `STATIC=true` is specified.

This tool was originally written when Linux had no standard interface for EPB, or HWP support. Retain the capability to manage a system w/o any kernel PM support, but prefer the standard kernel interfaces, when avaialble. (not doing so led to a confusing conflict between a p-state limit request made via cpufreq and modified by the intel-pstate driver, versus the raw MSR write made by this utility) Signed-off-by: Len Brown
