Allow the user to specify a local engine index (as opposed to class:index) that they can use to refer to a preset engine inside the ctx->engine[] array defined by an earlier I915_CONTEXT_PARAM_ENGINES. This will be useful for setting SSEU parameters on virtual engines that are local to the context and do not have a valid global class:instance lookup. Note that due to the ambiguity in using class:instance with ctx->engines[], if a user supplied engine map is active the user must specify the engine to alter by its index into the ctx->engines[].

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.
