Gurchetan Singh 7547675b84 drm/virtio: implement context init: track {ring_idx, emit_fence_info} in virtio_gpu_fence
Each fence should be associated with a [fence ID, fence_context,
seqno].  The seqno number is just the fence id.

To get the fence context, we add the ring_idx to the 3D context's
base_fence_ctx.  The ring_idx is between 0 and 31, inclusive.

Each 3D context will have it's own base_fence_ctx. The ring_idx will
be emitted to host userspace, when emit_fence_info is true.

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.
