Like detailed in commit 927dfdd09d ("drm/i915/dg2: Add SQIDI
steering"), some registers are expected to have the selector
initialized just once and never set to anything else. For xe, the
registers with SQIDI replication type (SF and MCFG) were missing,
resulting in warnings like:
[ 410.685565] xe 0000:03:00.0: Did not find MCR register 0x8724 in any MCR steering table
While adding these registers, abstract the handling for
"dg2_gam_ranges", moving them together with SF/MCFG to a dedicated
table. This also avoids that range to be checked for platforms other
than DG2. For DG2, this is the new steering output:
# cat /sys/kernel/debug/dri/0/gt0/steering
...
IMPLICIT steering: group=0x0, instance=0x0
0x000b00 - 0x000bff
0x001000 - 0x001fff
0x004000 - 0x004aff
0x008700 - 0x0087ff
0x00c800 - 0x00cfff
0x00f000 - 0x00ffff

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.
