[Why] DPIA traces from DMUB is not enabled by default, which is less convenient to debug DPIA related issues because we have to resort to other means to enable DPIA trace. [How] Reuse existing DC debug mask to enable DPIA trace log from kernel command line. This makes debugging DPIA issues easier especially when system power state (suspend/reboot) is involved. To turn on DPIA trace, simply add "amdgpu.dcdebugmask=0x80" to kernel command line.

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.
