[GIT PULL] Power management updates for v6.13-rc1

[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.13-rc1

with top-most commit c6e2a4c9eed5249c4158bc621882d44e94af3371

 Merge branch 'pm-tools'

on top of commit 1a1030d10a6335bb5e6cdb24fc9388d3d9bcc1ac

 cpufreq: intel_pstate: Rearrange locking in hybrid_init_cpu_capacity_scaling()

to receive power management updates for 6.13-rc1.

The amd-pstate cpufreq driver gets the majority of changes this time.
They are mostly fixes and cleanups, but one of them causes it to become
the default cpufreq driver on some AMD server platforms.

Apart from that, the menu cpuidle governor is modified to not use iowait
any more, the intel_idle gets a custom C-states table for Granite Rapids
Xeon D, and the intel_pstate driver will use a more aggressive Balance-
performance default EPP value on Granite Rapids now.

There are also some fixes, cleanups and tooling updates.

Specifics:

 - Update the amd-pstate driver to set the initial scaling frequency
   policy lower bound to be the lowest non-linear frequency (Dhananjay
   Ugwekar).

 - Enable amd-pstate by default on servers starting with newer AMD Epyc
   processors (Swapnil Sapkal).

 - Align more codepaths between shared memory and MSR designs in
   amd-pstate (Dhananjay Ugwekar).

 - Clean up amd-pstate code to rename functions and remove redundant
   calls (Dhananjay Ugwekar, Mario Limonciello).

 - Do other assorted fixes and cleanups in amd-pstate (Dhananjay Ugwekar
   and Mario Limonciello).

 - Change the Balance-performance EPP value for Granite Rapids in the
   intel_pstate driver to a more performance-biased one (Srinivas
   Pandruvada).

 - Simplify MSR read on the boot CPU in the ACPI cpufreq driver (Chang
   S. Bae).

 - Ensure sugov_eas_rebuild_sd() is always called when sugov_init()
   succeeds to always enforce sched domains rebuild in case EAS needs
   to be enabled (Christian Loehle).

 - Switch cpufreq back to platform_driver::remove() (Uwe Kleine-König).

 - Use proper frequency unit names in cpufreq (Marcin Juszkiewicz).

 - Add a built-in idle states table for Granite Rapids Xeon D to the
   intel_idle driver (Artem Bityutskiy).

 - Fix some typos in comments in the cpuidle core and drivers (Shen
   Lichuan).

 - Remove iowait influence from the menu cpuidle governor (Christian
   Loehle).

 - Add min/max available performance state limits to the Energy Model
   management code (Lukasz Luba).

 - Update pm-graph to v5.13 (Todd Brandt).

 - Add documentation for some recently introduced cpupower utility
   options (Tor Vic).

 - Make cpupower inform users where cpufreq-bench.conf should be located
   when opening it fails (Peng Fan).

 - Allow overriding cross-compiling env params in cpupower (Peng Fan).

 - Add compile_commands.json to .gitignore in cpupower (John B. Wyatt
   IV).

 - Improve disable c_state block in cpupower bindings and add a test to
   confirm that CPU state is disabled to it (John B. Wyatt IV).

 - Add Chinese Simplified translation to cpupower (Kieran Moy).

 - Add checks for xgettext and msgfmt to cpupower (Siddharth Menon).

Thanks!
