Even though soft reset should ideally never fail, during development of some power management features I managed to get some bits wrong: this resulted in GPU soft reset failures, where the GPU was never able to recover, not even after suspend/resume cycles, meaning that the only way to get functionality back was to reboot the machine. Perform a hard reset after a soft reset failure to be able to recover the GPU during runtime (so, without any machine reboot).

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.
