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)"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
