Add LRC descriptor context lookup array which can resolve the intel_context from the LRC descriptor index. In addition to lookup, it can determine if the LRC descriptor context is currently registered with the GuC by checking if an entry for a descriptor index is present. Future patches in the series will make use of this array. v2: (Michal) - "linux/xarray.h" -> <linux/xarray.h> - s/lrc/LRC (John H) - Fix commit message Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210721215101.139794-4-matthew.brost@intel.com
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.
