Summary of changes: Till the commit: "tools/power/x86/intel-speed-select: Get punit core mapping information" All patches just lays foundation for adding new hardware interface in addition to existing MSR/MMIO interface. All patches prefixed with "Abstract" just adds individual hardware callback for functions called from the core processing. The mailbox processing is abstracted to a new file with callbacks. In addition some changes to reduce duplicated code for display of TRL level. Patch "Introduce Punit ID concept and add related API" add further abstraction in addition to existing package and die scope. ----------- tools/power/x86/intel-speed-select: Get punit core mapping information -Adds a new way to get package/die/punit information for each CPU. ----------- Introduce TPMI interface support - Implement all abstracted callbacks above to use TPMI IOCTL interface. ----------- tools/power/x86/intel-speed-select: Display punit info - With TPMI the granularity is per punit, which can be multiple in a package/die. ---------- tools/power/x86/intel-speed-select: Remove cpu mask display for non-cpu power domain tools/power/x86/intel-speed-select: Display fact info for non-cpu power domain -There are some power domains with no CPUs, the above patches adds CPU as invalid for these domains ---------- tools/power/x86/intel-speed-select: Use cgroup v2 isolation - Adds new option to use Cgroup CPU isolation instead of offline of CPUs ---------- tools/power/x86/intel-speed-select: Change TRL display for Emerald Rapids - Emerald Rapid has multiple TRL levels and moves away from TRL level based on instruction type
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
