At present i915 does not fetch busyness information from GuC, resulting in
incorrect busyness values in fdinfo. Because engine information is coupled
with busyness in fdinfo, skip showing client engine information in fdinfo
with GuC submission till fetching busyness is supported in the i915 GuC
submission backend.
v2 (Daniele):
Make commit title and description more precise
Add FIXME with brief description at code change
s/intel_guc_submission_is_used/intel_uc_uses_guc_submission/
v3 (Daniele):

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.
