For non-RCS engines, nearly all of the LRC state is composed of MI instructions (specifically MI_LOAD_REGISTER_IMM). Providing a dump interface allows us to verify that the context image layout matches what's documented in the bspec, and also allows us to check whether LRC workarounds are being properly captured by the default state we record at startup. For now, the non-MI instructions found in the RCS and CCS engines will dump as "unknown;" parsing of those will be added in a follow-up patch. v2: - Add raw instruction header as well as decoded meaning. (Lucas) - Check that num_dw isn't greater than remaining_dw for instructions that have a "# dwords" field. (Lucas) - Clarify comment about skipping over ppHWSP.

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.
