Unwedging the GPU requires a successful GPU reset before we restore the default submission, or else we may see residual context switch events that we were not expecting. v2: Pull in the special-case reset_clobbers_display, and explain why it should be safe in the context of unwedging. v3: Just forget all about resets before unwedging if it will clobber the display; risk it all.

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.
