When bit 19 of MI_LOAD_REGISTER_IMM instruction opcode is set on tgl+ devices, HW does not care about certain register address offsets, but instead check the following for valid address ranges on specific engines: RCS && CCS: BITS(0 - 10) BCS: BITS(0 - 11) VECS && VCS: BITS(0 - 13) Also, tgl+ now support relative addressing for BCS engine - So, this patch fixes issue with live_gt_lrc selftest that is failing where there is mismatch between LRC register layout generated during init and HW default register offsets.

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.
