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.

Since the commit 948fb096 ("clk: Always clamp the rounded rate"), the clk_core_determine_round_nolock() would clamp the requested rate between min and max rates from the rate request. Normally these fields would be filled by clk_core_get_boundaries() called from clk_round_rate(). However clk_gfx3d_determine_rate() uses a manually crafted rate request, which did not have these fields filled. Thus the requested frequency would be clamped to 0, resulting in weird frequencies being requested from the hardware. Fix this by filling min_rate and max_rate to the values valid for the respective PLLs (0 and ULONG_MAX).
