Documentation: amd-pstate:fix minimum performance state label error
In the AMD P-States Performance Scale diagram, the labels for "Max Perf" and "Lowest Perf" were incorrectly used to define the range for "Desired Perf".The "Desired performance target" should be bounded by the "Maximum requested performance" and the "Minimum requested performance", which corresponds to "Max Perf" and "Min Perf", respectively.

Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.
Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).
There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.
In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.
Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.
Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.
Specifics:
- Fix potential division-by-zero error in em_compute_costs() (Yaxiong
Tian)
- Fix typos in energy model documentation and example driver code
(Moon Hee Lee, Atul Kumar Pant)

Power management updates for 6.15-rc1
- Manage sysfs attributes and boost frequencies efficiently from
cpufreq core to reduce boilerplate code in drivers (Viresh Kumar).
- Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
Dhananjay Ugwekar, Imran Shaik, zuoqian).
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai).
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski).
- Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng).
- Optimize the amd-pstate driver to avoid cases where call paths end
up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar).
- Make it possible to avoid enabling capacity-aware scheduling (CAS) in
the intel_pstate driver and relocate a check for out-of-band (OOB)
platform handling in it to make it detect OOB before checking HWP
availability (Rafael Wysocki).
- Fix dbs_update() to avoid inadvertent conversions of negative integer
values to unsigned int which causes CPU frequency selection to be
inaccurate in some cases when the "conservative" cpufreq governor is
in use (Jie Zhan).
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki).
- Make it possible to tell the intel_idle driver to ignore its built-in
table of idle states for the given processor, clean up the handling
of auto-demotion disabling on Baytrail and Cherrytrail chips in it,
and update its MAINTAINERS entry (David Arcari, Artem Bityutskiy,
Rafael Wysocki).
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai).
- Clean up the Energy Model handling code somewhat (Rafael Wysocki).
- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing).
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba).
- Address RCU-related sparse warnings in the Energy Model code (Rafael
Wysocki).
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao).
- Unify error handling during runtime suspend and runtime resume in the
core to help drivers to implement more consistent runtime PM error
handling (Rafael Wysocki).
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki).
- Rework the handling of the "smart suspend" driver flag in the PM core
to avoid issues hat may occur when drivers using it depend on some
other drivers and clean up the related PM core code (Rafael Wysocki,
Colin Ian King).
- Fix the handling of devices with the power.direct_complete flag set
if device_suspend() returns an error for at least one device to avoid
situations in which some of them may not be resumed (Rafael Wysocki).
- Use mutex_trylock() in hibernate_compressor_param_set() to avoid a
possible deadlock that may occur if the "compressor" hibernation
module parameter is accessed during the registration of a new
ieee80211 device (Lizhi Xu).
- Suppress sleeping parent warning in device_pm_add() in the case when
new children are added under a device with the power.direct_complete
set after it has been processed by device_resume() (Xu Yang).

Pull power management updates from Rafael Wysocki:
"These are dominated by cpufreq updates which in turn are dominated by
updates related to boost support in the core and drivers and
amd-pstate driver optimizations.
Apart from the above, there are some cpuidle updates including a
rework of the most recent idle intervals handling in the venerable
menu governor that leads to significant improvements in some
performance benchmarks, as the governor is now more likely to predict
a shorter idle duration in some cases, and there are updates of the
core device power management code, mostly related to system suspend
and resume, that should help to avoid potential issues arising when
the drivers of devices depending on one another want to use different
optimizations.
There is also a usual collection of assorted fixes and cleanups,
including removal of some unused code.

cpufreq: intel_pstate: Make it possible to avoid enabling CAS
Capacity-aware scheduling (CAS) is enabled by default by intel_pstate on hybrid systems without SMT, but in some usage scenarios it may be more attractive to place tasks for maximum CPU performance regardless of the extra cost in terms of energy, which is the case on such systems when CAS is not enabled, so introduce a command line option to forbid intel_pstate to enable CAS.

cpufreq: Introduce an optional cpuinfo_avg_freq sysfs entry
Currently the CPUFreq core exposes two sysfs attributes that can be used to query current frequency of a given CPU(s): namely cpuinfo_cur_freq and scaling_cur_freq. Both provide slightly different view on the subject and they do come with their own drawbacks. cpuinfo_cur_freq provides higher precision though at a cost of being rather expensive. Moreover, the information retrieved via this attribute is somewhat short lived as frequency can change at any point of time making it difficult to reason from. scaling_cur_freq, on the other hand, tends to be less accurate but then the actual level of precision (and source of information) varies between architectures making it a bit ambiguous. The new attribute, cpuinfo_avg_freq, is intended to provide more stable, distinct interface, exposing an average frequency of a given CPU(s), as reported by the hardware, over a time frame spanning no more than a few milliseconds. As it requires appropriate hardware support, this interface is optional. Note that under the hood, the new attribute relies on the information provided by arch_freq_get_on_cpu, which, up to this point, has been feeding data for scaling_cur_freq attribute, being the source of ambiguity when it comes to interpretation. This has been amended by restoring the intended behavior for scaling_cur_freq, with a new dedicated config option to maintain status quo for those, who may need it.

platform/x86/intel-uncore-freq: Support for cluster level controls
An SoC can contain multiple power domains with individual or collection
of mesh partitions. This partition is called fabric cluster.
Certain type of meshes will need to run at the same frequency, they will
be placed in the same fabric cluster. Benefit of fabric cluster is that
it offers a scalable mechanism to deal with partitioned fabrics in a SoC.
The current sysfs interface supports control at package and die level.
This interface is not enough to support more granular control at
fabric cluster level.
SoCs with the support of TPMI (Topology Aware Register and PM Capsule
Interface), can have multiple power domains. Each power domain can
contain one or more fabric clusters.
To support such granular controls, enhance uncore common to optionally
create new directories to provide controls at fabric cluster level. It
is also important to have flexibility to change granularity for future
version of SoCs. If the directory name contains scope like:
"package_*_die_*_power_domain_*_cluster_*", then this is not expandable.
The cpufreq policies also have different scopes. There the scope of the
policy (affected_cpus) specified by attributes inside each policy.
So, follow the same model for uncore frequency scaling sysfs as:
"sys/devices/system/cpu/cpufreq/policy*"
Allow client drivers to optionally support granular control for each
fabric cluster. Here, the directory name will be "uncore" suffixed with
an unique instance number. For example: uncore00, uncore01 etc.
Attributes in the directory identify package id, power domain and
fabric cluster id. This interface is expandable even if some new level
of granularity is introduced. A new sysfs attribute can identify new
level.
For compatibility with the existing sysfs and provide easy way to set
limits for each fabric cluster in the package/die, the existing control
at package/die levels are still provided. For majority of users, this is
an easy approach.
For example: On a single package/die system, with three power domains
and one fabric cluster per power domain:
$tree -L 2 /sys/devices/system/cpu/intel_uncore_frequency/
/sys/devices/system/cpu/intel_uncore_frequency/
├── package_00_die_00
│ ├── current_freq_khz

├── uncore00

├── fabric_cluster_id
├── initial_max_freq_khz
├── initial_min_freq_khz
├── max_freq_khz
├── min_freq_khz
└── package_id
The attribute for cluster id is "fabric_cluster_id" instead of just
"cluster_id" is to avoid confusion with usage of term clusters in
other part of the Linux kernel.

docs: ftrace: always use canonical ftrace path
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing Many parts of Documentation still reference this older debugfs path, so let's update them to avoid confusion.

x86: Handle idle=nomwait cmdline properly for x86_idle
When kernel is booted with idle=nomwait do not use MWAIT as the default idle state. If the user boots the kernel with idle=nomwait, it is a clear direction to not use mwait as the default idle state. However, the current code does not take this into consideration while selecting the default idle state on x86. Fix it by checking for the idle=nomwait boot option in prefer_mwait_c1_over_halt(). Also update the documentation around idle=nomwait appropriately.
