Pull power management updates from Rafael Wysocki: "By the number of new lines of code, the most visible change here is the addition of hybrid CPU capacity scaling support to the intel_pstate driver. Next are the amd-pstate driver changes related to the calculation of the AMD boost numerator and preferred core detection. As far as new hardware support is concerned, the intel_idle driver will now handle Granite Rapids Xeon processors natively, the intel_rapl power capping driver will recognize family 1Ah of AMD processors and Intel ArrowLake-U chipos, and intel_pstate will handle Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode. Apart from the above, there is a usual collection of assorted fixes and code cleanups in many places and there are tooling updates. Specifics: - Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef) - Add support for Granite Rapids and Sierra Forest in OOB mode to the intel_pstate cpufreq driver (Srinivas Pandruvada) - Add basic support for CPU capacity scaling on x86 and make the intel_pstate driver set asymmetric CPU capacity on hybrid systems without SMT (Rafael Wysocki) - Add missing MODULE_DESCRIPTION() macros to the powerpc cpufreq driver (Jeff Johnson) - Several OF related cleanups in cpufreq drivers (Rob Herring) - Enable COMPILE_TEST for ARM drivers (Rob Herrring) - Introduce quirks for syscon failures and use socinfo to get revision for TI cpufreq driver (Dhruva Gole, Nishanth Menon) - Minor cleanups in amd-pstate driver (Anastasia Belova, Dhananjay Ugwekar) - Minor cleanups for loongson, cpufreq-dt and powernv cpufreq drivers (Danila Tikhonov, Huacai Chen, and Liu Jing) - Make amd-pstate validate return of any attempt to update EPP limits, which fixes the masking hardware problems (Mario Limonciello) - Move the calculation of the AMD boost numerator outside of amd-pstate, correcting acpi-cpufreq on systems with preferred cores (Mario Limonciello) - Harden preferred core detection in amd-pstate to avoid potential false positives (Mario Limonciello) - Add extra unit test coverage for mode state machine (Mario Limonciello) - Fix an "Uninitialized variables" issue in amd-pstste (Qianqiang Liu) - Add Granite Rapids Xeon support to intel_idle (Artem Bityutskiy) - Disable promotion to C1E on Jasper Lake and Elkhart Lake in intel_idle (Kai-Heng Feng) - Use scoped device node handling to fix missing of_node_put() and simplify walking OF children in the riscv-sbi cpuidle driver (Krzysztof Kozlowski) - Remove dead code from cpuidle_enter_state() (Dhruva Gole) - Change an error pointer to NULL to fix error handling in the intel_rapl power capping driver (Dan Carpenter) - Fix off by one in get_rpi() in the intel_rapl power capping driver (Dan Carpenter) - Add support for ArrowLake-U to the intel_rapl power capping driver (Sumeet Pawnikar) - Fix the energy-pkg event for AMD CPUs in the intel_rapl power capping driver (Dhananjay Ugwekar) - Add support for AMD family 1Ah processors to the intel_rapl power capping driver (Dhananjay Ugwekar) - Remove unused stub for saveable_highmem_page() and remove deprecated macros from power management documentation (Andy Shevchenko) - Use ysfs_emit() and sysfs_emit_at() in "show" functions in the PM sysfs interface (Xueqin Luo) - Update the maintainers information for the operating-points-v2-ti-cpu DT binding (Dhruva Gole) - Drop unnecessary of_match_ptr() from ti-opp-supply (Rob Herring) - Add missing MODULE_DESCRIPTION() macros to devfreq governors (Jeff Johnson) - Use devm_clk_get_enabled() in the exynos-bus devfreq driver (Anand Moon) - Use of_property_present() instead of of_get_property() in the imx-bus devfreq driver (Rob Herring) - Update directory handling and installation process in the pm-graph Makefile and add .gitignore to ignore sleepgraph.py artifacts to pm-graph (Amit Vadhavana, Yo-Jung Lin) - Make cpupower display residency value in idle-info (Aboorva Devarajan) - Add missing powercap_set_enabled() stub function to cpupower (John B. Wyatt IV) - Add SWIG support to cpupower (John B. Wyatt IV)" * tag 'pm-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (62 commits) cpufreq/amd-pstate-ut: Fix an "Uninitialized variables" issue cpufreq/amd-pstate-ut: Add test case for mode switches cpufreq/amd-pstate: Export symbols for changing modes amd-pstate: Add missing documentation for `amd_pstate_prefcore_ranking` cpufreq: amd-pstate: Add documentation for `amd_pstate_hw_prefcore` cpufreq: amd-pstate: Optimize amd_pstate_update_limits() cpufreq: amd-pstate: Merge amd_pstate_highest_perf_set() into amd_get_boost_ratio_numerator() x86/amd: Detect preferred cores in amd_get_boost_ratio_numerator() x86/amd: Move amd_get_highest_perf() out of amd-pstate ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn ACPI: CPPC: Drop check for non zero perf ratio x86/amd: Rename amd_get_highest_perf() to amd_get_boost_ratio_numerator() ACPI: CPPC: Adjust return code for inline functions in !CONFIG_ACPI_CPPC_LIB x86/amd: Move amd_get_highest_perf() from amd.c to cppc.c PM: hibernate: Remove unused stub for saveable_highmem_page() pm:cpupower: Add error warning when SWIG is not installed MAINTAINERS: Add Maintainers for SWIG Python bindings pm:cpupower: Include test_raw_pylibcpupower.py pm:cpupower: Add SWIG bindings files for libcpupower pm:cpupower: Add missing powercap_set_enabled() stub function ...
