Pull power management updates from Rafael Wysocki:
"These add a new power capping facility allowing aggregate power
constraints to be applied to sets of devices in a distributed manner,
add a new CPU ID to the RAPL power capping driver and improve it, drop
a cpufreq driver belonging to a platform that is not supported any
more, drop two redundant cpufreq driver flags, update cpufreq drivers
(intel_pstate, brcmstb-avs, qcom-hw), update the operating performance
points (OPP) framework (code cleanups, new helpers, devfreq-related
modifications), clean up devfreq, extend the PM clock layer, update
the cpupower utility and make assorted janitorial changes.

Specifics:

- Add new power capping facility called DTPM (Dynamic Thermal Power
Management), based on the existing power capping framework, to
allow aggregate power constraints to be applied to sets of devices
in a distributed manner, along with a CPU backend driver based on
the Energy Model (Daniel Lezcano, Dan Carpenter, Colin Ian King).

- Add AlderLake Mobile support to the Intel RAPL power capping driver
and make it use the topology interface when laying out the system
topology (Zhang Rui, Yunfeng Ye).

- Drop the cpufreq tango driver belonging to a platform that is not
supported any more (Arnd Bergmann).

- Drop the redundant CPUFREQ_STICKY and CPUFREQ_PM_NO_WARN cpufreq
driver flags (Viresh Kumar).

- Update cpufreq drivers:

* Fix max CPU frequency discovery in the intel_pstate driver and
make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel
Christian).

* Fix resource leaks in the brcmstb-avs-cpufreq driver (Christophe
JAILLET).

* Make the tegra20 driver use the resource-managed API (Dmitry
Osipenko).

* Enable boost support in the qcom-hw driver (Shawn Guo).

- Update the operating performance points (OPP) framework:

* Clean up the OPP core (Dmitry Osipenko, Viresh Kumar).

* Extend the OPP API by adding new helpers to it (Dmitry Osipenko,
Viresh Kumar).

* Allow required OPPs to be used for devfreq devices and update
the devfreq governor code accordingly (Saravana Kannan).

* Prepare the framework for introducing new dev_pm_opp_set_opp()
helper (Viresh Kumar).

* Drop dev_pm_opp_set_bw() and update related drivers (Viresh
Kumar).

* Allow lazy linking of required-OPPs (Viresh Kumar).

- Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li,
Pierre Kuo).

- Update the generic power domains (genpd) framework:

* Use device's next wakeup to determine domain idle state (Lina
Iyer).

* Improve initialization and debug (Dmitry Osipenko).

* Simplify computations (Abaci Team).

- Make janitorial changes in the core code handling system sleep and
PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn,
Zqiang).

- Update the MAINTAINERS entry for the exynos cpuidle driver and drop
DEBUG definition from intel_idle (Krzysztof Kozlowski, Tom Rix).

- Extend the PM clock layer to cover clocks that must sleep (Nicolas
Pitre).

- Update the cpupower utility:

* Update cpupower command, add support for AMD family 0x19 and
clean up the code to remove many of the family checks to make
future family updates easier (Nathan Fontenot, Robert Richter).

* Add Makefile dependencies for install targets to allow building
cpupower in parallel rather than serially (Ivan Babrou).

- Make janitorial changes in power management Kconfig (Lukasz Luba)"

The cpuid flag is set when CPUID_80000007_EDX[7] is set,
which is all families >= 10h. The check excludes family 14h
because HW pstate reporting was not implemented on family 14h.

This is intended to reduce family checks in the main code paths.

Merge tag 'pm-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These include cpuidle changes to use nanoseconds (instead of
microseconds) as the unit of time and to simplify checks for disabled
idle states in the idle loop, some cpuidle fixes and governor updates,
assorted cpufreq updates (driver updates mostly and a few core fixes
and cleanups), devfreq updates (dominated by the tegra30 driver
changes), new CPU IDs for the RAPL power capping driver, relatively
minor updates of the generic power domains (genpd) and operation
performance points (OPP) frameworks, and assorted fixes and cleanups.

There are also two maintainer information updates: Chanwoo Choi will
be maintaining the devfreq subsystem going forward and Todd Brandt is
going to maintain the pm-graph utility (created by him).

Specifics:

- Use nanoseconds (instead of microseconds) as the unit of time in
the cpuidle core and simplify checks for disabled idle states in
the idle loop (Rafael Wysocki)

- Fix and clean up the teo cpuidle governor (Rafael Wysocki)

- Fix the cpuidle registration error code path (Zhenzhong Duan)

- Avoid excessive vmexits in the ACPI cpuidle driver (Yin Fengwei)

- Extend the idle injection infrastructure to be able to measure the
requested duration in nanoseconds and to allow an exit latency
limit for idle states to be specified (Daniel Lezcano)

- Fix cpufreq driver registration and clarify a comment in the
cpufreq core (Viresh Kumar)

- Add NULL checks to the show() and store() methods of sysfs
attributes exposed by cpufreq (Kai Shen)

- Update cpufreq drivers:
* Fix for a plain int as pointer warning from sparse in
intel_pstate (Jamal Shareef)
* Fix for a hardcoded number of CPUs and stack bloat in the
powernv driver (John Hubbard)
* Updates to the ti-cpufreq driver and DT files to support new
platforms and migrate bindings from opp-v1 to opp-v2 (Adam Ford,
H. Nikolaus Schaller)
* Merging of the arm_big_little and vexpress-spc drivers and
related cleanup (Sudeep Holla)
* Fix for imx's default speed grade value (Anson Huang)
* Minor cleanup of the s3c64xx driver (Nathan Chancellor)
* CPU speed bin detection fix for sun50i (Ondrej Jirman)

- Appoint Chanwoo Choi as the new devfreq maintainer.

- Update the devfreq core:
* Check NULL governor in available_governors_show sysfs to prevent
showing wrong governor information and fix a race condition
between devfreq_update_status() and trans_stat_show() (Leonard
Crestez)
* Add new 'interrupt-driven' flag for devfreq governors to allow
interrupt-driven governors to prevent the devfreq core from
polling devices for status (Dmitry Osipenko)
* Improve an error message in devfreq_add_device() (Matthias
Kaehlcke)

- Update devfreq drivers:
* tegra30 driver fixes and cleanups (Dmitry Osipenko)
* Removal of unused property from dt-binding documentation for the
exynos-bus driver (Kamil Konieczny)
* exynos-ppmu cleanup and DT bindings update (Lukasz Luba, Marek
Szyprowski)

- Add new CPU IDs for CometLake Mobile and Desktop to the Intel RAPL
power capping driver (Zhang Rui)

- Allow device initialization in the generic power domains (genpd)
framework to be more straightforward and clean it up (Ulf Hansson)

- Add support for adjusting OPP voltages at run time to the OPP
framework (Stephen Boyd)

- Avoid freeing memory that has never been allocated in the
hibernation core (Andy Whitcroft)

- Clean up function headers in a header file and coding style in the
wakeup IRQs handling code (Ulf Hansson, Xiaofei Tan)

- Clean up the SmartReflex adaptive voltage scaling (AVS) driver for
ARM (Ben Dooks, Geert Uytterhoeven)

- Wrap power management documentation to fit in 80 columns (Bjorn
Helgaas)

- Add pm-graph utility entry to MAINTAINERS (Todd Brandt)

AMD Zen 2 introduces the RDPRU instruction which can be used to access some

0. ECX specifies the register to read and EDX:EAX will contain the value read.

ECX: 0 - Register MPERF

This has the added advantage of not having to use the msr module, since the
userspace to kernel transitions which occur during each read_msr() might
cause APERF and MPERF to go out of sync.
