GPU cores with the DYNAMIC_FREQUENCY_SCALING feature bit set expect the platform to provide the clock scaling and ignore any requests to use the internal FSCALE divider. Writes to this register still work, but don't have any effect on the GPU clock frequency. Save the initial core and shader clock frequency and ask the platform to provide a slower clock when cooling is requested. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
