Implement GuC commands and response along with the Context
Group Page (CGP) interface for multi queue support.
Ensure that only primary queue (q0) of a multi queue group
communicate with GuC. The secondary queues of the group only
need to maintain LRCA and interface with drm scheduler.
Use primary queue's submit_wq for all secondary queues of a multi
queue group. This serialization avoids any locking around CGP
synchronization with GuC.
v2: Fix G2H_LEN_DW_MULTI_QUEUE_CONTEXT value, add more comments
(Matt Brost)
v3: Minor code refactro, use xe_gt_assert
v4: Use xe_guc_ct_wake_waiters(), remove vf recovery support

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 reStructuredText 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.
