Matt Roper bc78bfd287 drm/xe/xe2_hpg: Fix handling of Wa_14019988906 & Wa_14019877138 
[ Upstream commit bc6387a2e0 ]

The PSS_CHICKEN register has been part of the RCS engine's LRC since it
was first introduced in Xe_LP.  That means that any workarounds that
adjust its value (such as Wa_14019988906 and Wa_14019877138) need to be
implemented in the lrc_was[] table so that they become part of the
default LRC from which all subsequent LRCs are copied.  Although these
workarounds were implemented correctly on most platforms, they were
incorrectly placed on the engine_was[] table for Xe2_HPG.

Move the workarounds to the proper lrc_was[] table and switch the
'xe_rtp_match_first_render_or_compute' rule to specifically match the
RCS since that's the engine whose LRC manages the register.

README 

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 reStructuredText 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.
