We seem to have a case where SDMA will sometimes miss a doorbell if GFX is entering the powergating state when the doorbell comes in. To workaround this, we can update the wptr via MMIO, however, this is only safe because we disallow gfxoff in begin_ring() for SDMA 5.2 and then allow it again in end_ring(). Enable this workaround while we are root causing the issue with the HW team.

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 reStructuredText 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.
