In the case of a full GPU reset (e.g. because GuC has died or because GuC's hang detection has been disabled), the driver can't rely on GuC reporting the guilty context. Instead, the driver needs to scan all active contexts and find one that is currently executing, as per the execlist mode behaviour. In GuC mode, this scan is different to execlist mode as the active request list is handled very differently. Similarly, the request state dump in debugfs needs to be handled differently when in GuC submission mode. Also refactured some of the request scanning code to avoid duplication across the multiple code paths that are now replicating it.

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.
