Linux kernel source tree
632c4bf6d0
The same as Sapphire Rapids, Granite Rapids also supports the discovery table feature. All the basic uncore PMON information can be retrieved from the discovery table which resides in the BIOS. There are 4 new units are added on Granite Rapids, b2cmi, b2cxl, ubox, and mdf_sbo. The layout of the counters is exactly the same as the generic uncore counters. Only add a name for the new units. All the details can be retrieved from the discovery table. The description of the new units can be found at https://www.intel.com/content/www/us/en/secure/content-details/772943/content-details.html The other units, e.g., cha, iio, irp, pcu, and imc, are the same as Sapphire Rapids. Ignore the upi and b2upi units in the discovery table, which are broken for now.

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.
