Read HFI (Hardware Feedback Interface) events to process config level
changes in oob mode. When HFI is supported there is no need for polling
to check config level change.
Subscribe to Linux thermal netlink messages and process message:

tools/power/x86/intel-speed-select: OOB daemon mode2022-02-17T18:57:25ZSrinivas Pandruvadasrinivas.pandruvada@linux.intel.com2022-01-18T23:02:57Zurn:sha1:7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6
It is possible that some out of band agent changed config level. In this
case CPUs need to be online/offline to support this config change. Add
a command line option --oob, so that this tool can run as daemon and poll
for config level change and take action. The poll interval is configurable
in seconds using config option --poll-interval.

tools/power/x86: A tool to validate Intel Speed Select commands2019-07-03T12:37:09ZSrinivas Pandruvadasrinivas.pandruvada@linux.intel.com2019-06-30T17:14:08Zurn:sha1:3fb4f7cd472c7f5905c91508e988f6b28372210d
The Intel(R) Speed select technologies contains four features.
Performance profile:An non architectural mechanism that allows multiple
optimized performance profiles per system via static and/or dynamic
adjustment of core count, workload, Tjmax, and TDP, etc. aka ISS
in the documentation.
Base Frequency: Enables users to increase guaranteed base frequency on
certain cores (high priority cores) in exchange for lower base frequency
on remaining cores (low priority cores). aka PBF in the documenation.
Turbo frequency: Enables the ability to set different turbo ratio limits
to cores based on priority. aka FACT in the documentation.
Core power: An Interface that allows user to define per core/tile
priority.
There is a multi level help for commands and options. This can be used
to check required arguments for each feature and commands for the
feature.
To start navigating the features start with
$sudo intel-speed-select --help
For help on a specific feature for example
$sudo intel-speed-select perf-profile --help
To get help for a command for a feature for example
$sudo intel-speed-select perf-profile get-lock-status --help
