The Wa_14017073508 require to send Media Busy/Idle mailbox while accessing Media tile. As of now it is getting handled while __gt_unpark, __gt_park. But there are various corner cases where forcewakes are taken without __gt_unpark i.e. without sending Busy Mailbox especially during register reads. Forcewakes are taken without busy mailbox leads to GPU HANG. So bringing mailbox calls under forcewake calls are no feasible option as forcewake calls are atomic and mailbox calls are blocking. The issue already fixed in B step so disabling MC6 on A step and reverting previous commit which handles Wa_14017073508 Fixes: |

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.
