Pull power management updates from Rafael Wysocki:
"The majority of changes here are cpufreq updates which are dominated
by amd-pstate driver changes, like in the previous cycle. Moreover,
changes related to amd-pstate are also the majority of cpupower
utility updates.

Included are some pieces of new hardware support, like the addition of
Clearwater Forest processors support to intel_idle, new cpufreq driver
for Airoha SoCs, and Apple cpufreq driver extensions to support more
SoCs. The intel_pstate driver is also extended to be able to support
new platforms by using ACPI CPPC to compute scaling factors between
HWP performance states and frequency.

The rest is mostly fixes and cleanups in assorted pieces of power
management code.

Specifics:

- Use str_enable_disable()-like helpers in cpufreq (Krzysztof
Kozlowski)

- Extend the Apple cpufreq driver to support more SoCs (Hector
Martin, Nick Chan)

- Add new cpufreq driver for Airoha SoCs (Christian Marangi)

- Fix using cpufreq-dt as module (Andreas Kemnade)

- Minor fixes for Sparc, SCMI, and Qcom cpufreq drivers (Ethan Carter
Edwards, Sibi Sankar, Manivannan Sadhasivam)

- Fix the maximum supported frequency computation in the ACPI cpufreq
driver to avoid relying on unfounded assumptions (Gautham Shenoy)

- Fix an amd-pstate driver regression with preferred core rankings
not being used (Mario Limonciello)

- Fix a precision issue with frequency calculation in the amd-pstate
driver (Naresh Solanki)

- Add ftrace event to the amd-pstate driver for active mode (Mario
Limonciello)

- Set default EPP policy on Ryzen processors in amd-pstate (Mario
Limonciello)

- Clean up the amd-pstate cpufreq driver and optimize it to increase
code reuse (Mario Limonciello, Dhananjay Ugwekar)

- Use CPPC to get scaling factors between HWP performance levels and
frequency in the intel_pstate driver and make it stop using a
built-in scaling factor for Arrow Lake processors (Rafael Wysocki)

- Make intel_pstate initialize epp_policy to CPUFREQ_POLICY_UNKNOWN
for consistency with CPU offline (Christian Loehle)

- Fix superfluous updates caused by need_freq_update in the schedutil
cpufreq governor (Sultan Alsawaf)

- Allow configuring the system suspend-resume (DPM) watchdog to warn
earlier than panic (Douglas Anderson)

- Implement devm_device_init_wakeup() helper and introduce a device-
managed variant of dev_pm_set_wake_irq() (Joe Hattori, Peng Fan)

- Remove direct inclusions of 'pm_wakeup.h' which should be only
included via 'device.h' (Wolfram Sang)

- Clean up two comments in the core system-wide PM code (Rafael
Wysocki, Randy Dunlap)

- Add Clearwater Forest processor support to the intel_idle cpuidle
driver (Artem Bityutskiy)

- Clean up the Exynos devfreq driver and devfreq core (Markus
Elfring, Jeongjun Park)

- Minor cleanups and fixes for OPP (Dan Carpenter, Neil Armstrong,
Joe Hattori)

- Implement dev_pm_opp_get_bw() (Neil Armstrong)

- Expose OPP reference counting helpers for Rust (Viresh Kumar)

- Fix TSC MHz calculation in cpupower (He Rongguang)

- Add install and uninstall options to bindings Makefile and add
header changes for cpufreq.h to SWIG bindings in cpupower (John B.
Wyatt IV)

- Add missing residency header changes in cpuidle.h to SWIG bindings
in cpupower (John B. Wyatt IV)

- Add output files to .gitignore and clean them up in "make clean" in
selftests/cpufreq (Li Zhijian)

- Fix cross-compilation in cpupower Makefile (Peng Fan)

- Revise the is_valid flag handling for idle_monitor in the cpupower
utility (wangfushuai)

- Extend and clean up AMD processors support in cpupower (Mario
Limonciello)"

Merge tag 'pm-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.

There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate
and more.

Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system
suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

Specifics:

- Allow the Energy Model to be updated dynamically (Lukasz Luba)

- Add support for LZ4 compression algorithm to the hibernation image
creation and loading code (Nikhil V)

- Fix and clean up system suspend statistics collection (Rafael
Wysocki)

Lin)

- Enable preferred core support in the amd-pstate cpufreq driver
(Meng Li)

- Fix min_perf assignment in amd_pstate_adjust_perf() and make the
min/max limit perf values in amd-pstate always stay within the
(highest perf, lowest perf) range (Tor Vic, Meng Li)

- Allow intel_pstate to assign model-specific values to strings used
in the EPP sysfs interface and make it do so on Meteor Lake
(Srinivas Pandruvada)

- Drop long-unused cpudata::prev_cummulative_iowait from the
intel_pstate cpufreq driver (Jiri Slaby)

- Prevent scaling_cur_freq from exceeding scaling_max_freq when the
latter is an inefficient frequency (Shivnandan Kumar)

- Change default transition delay in cpufreq to 2ms (Qais Yousef)

- Remove references to 10ms minimum sampling rate from comments in
the cpufreq code (Pierre Gondois)

- Honour transition_latency over transition_delay_us in cpufreq (Qais
Yousef)

- Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar)

- General enhancements / cleanups to ARM cpufreq drivers (tianyu2,
Nícolas F. R. A. Prado, Erick Archer, Arnd Bergmann, Anastasia
Belova)

- Make the SCMI cpufreq driver get a transition delay value from
firmware (Pierre Gondois)

poll_limit_ns below grow_start (Parshuram Sangle)

- Avoid potential overflow in integer multiplication when computing
cpuidle state parameters (C Cheng)

- Adjust MWAIT hint target C-state computation in the ACPI cpuidle
driver and in intel_idle to return a correct value for C0 (He
Rongguang)

PM: hibernate: Add support for LZ4 compression for hibernation

Extend the support for LZ4 compression to be used with hibernation.
The main idea is that different compression algorithms
have different characteristics and hibernation may benefit when it uses
any of these algorithms: a default algorithm, having higher
compression rate but is slower(compression/decompression) and a
secondary algorithm, that is faster(compression/decompression) but has
lower compression rate.

LZ4 algorithm has better decompression speeds over LZO. This reduces
the hibernation image restore time.
As per test results:
LZO LZ4
Size before Compression(bytes) 682696704 682393600
Size after Compression(bytes) 146502402 155993547
Decompression Rate 335.02 MB/s 501.05 MB/s
Restore time 4.4s 3.8s

LZO is the default compression algorithm used for hibernation. Enable
CONFIG_HIBERNATION_COMP_LZ4 to set the default compressor as LZ4.

PM: hibernate: Move to crypto APIs for LZO compression

Currently for hibernation, LZO is the only compression algorithm
available and uses the existing LZO library calls. However, there
is no flexibility to switch to other algorithms which provides better
results. The main idea is that different compression algorithms have
different characteristics and hibernation may benefit when it uses
alternate algorithms.

By moving to crypto based APIs, it lays a foundation to use other
compression algorithms for hibernation. There are no functional changes
introduced by this approach.
