Linux kernel source tree

The GFX doorbell solution provides a mechanism for submission of workload to the graphics hardware by a ring3 application without the penalty of ring transition for each workload submission. This feature is not currently used by the Linux drivers, but in SR-IOV mode the doorbells are treated as shared resource and the PF driver must be able to provision exclusive range of doorbells IDs across all enabled VFs. Introduce simple GuC doorbell ID manager that will be used by the PF driver for VFs provisioning and can later be used by submission code once we are ready to switch from H2G based notifications to doorbells mechanism.

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.
