The coarse power gating was disabled as part of commit 2248a28384fe
("drm/i915/gen8+: Add RC6 CTX corruption WA") as a prelude to recover
from the context corruption; the power gating itself has no direct
impact on the RC6 context corruption. However, that recovery scheme was
never implemented due to difficult corner cases, and so we no longer need
to keep the power gating disabled.

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.
