Starting GT freq is usually RPn. Raising freq to RP0 will help speed up GuC load times. As an example, this data was collected on DG2- GuC Load time @RPn ~ 41 ms GuC Load time @RP0 ~ 11 ms v2: Raise GT freq before hwconfig init. This will speed up both HuC and GuC loads. Address review comments (Rodrigo). Also add a small usleep after requesting frequency which gives pcode some time to react. v3: Address checkpatch issue Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
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.
