Goals of this new xe_gt_freq component: 1. Detach sysfs controls and raw freq management from GuC SLPC. 2. Create a directory that could later be aligned with devfreq. 3. Encapsulate all the freq control in a single directory. Although we only have one freq domain per GT, already start with a numbered freq0 directory so it could be expanded in the future if multiple domains or PLL are needed. Note: Although in the goal #1, the raw freq management control is mentioned, this patch only starts by the sysfs control. The RP freq configuration and init freq selection are still under the guc_pc, but should be moved to this component in a follow-up patch. v2: - Add /tile# to the doc and remove unnecessary kobject_put (Riana) - s/ssize_t/int on some ret variables (Vinay) Cc: Sujaritha Sundaresan <sujaritha.sundaresan@intel.com> Cc: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Cc: Riana Tauro <riana.tauro@intel.com> Reviewed-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.
