[why] Dummy pstate latency actually varies between different UCLK frequencies, when calculating watermark C, if DAL always assumes worst case, then it can lead to dummy pstate not supported scenarios. [how] Rather than statically calculating dummy pstate using worst case, we store the entire table of UCLK to dummy pstate relationships. On a per mode basis, we calculate the actual UCLK lower limit, and use the dynamic worst case dummy pstate latency. This prevents the situation where we don't support full p-state (which will force high DPM), but still use low DPM dummy pstate latency.

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.
