To facilitate the next patch to allow preemptible kernels not to incur the wrath of hangcheck, we need to ensure that we can still suspend and shutdown. That is we will not be able to rely on hangcheck to terminate a blocking kernel and instead must manually do so ourselves. The advantage is that we can apply more pressure! As we now perform a GPU reset to clean up any residual kernels, we leave the GPU in an unknown state and in particular can not talk to the GuC before we reinitialise it following resume. For example, we no longer need to tell the GuC to suspend itself, as it is already reset.

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.
