Similar to DRM_VMW_EVENT_FENCE_SIGNALED. Sends a pollable event to the DRM file descriptor when a fence on a specific ring is signaled. One difference is the event is not exposed via the UAPI -- this is because host responses are on a shared memory buffer of type BLOB_MEM_GUEST [this is the common way to receive responses with virtgpu]. As such, there is no context specific read(..) implementation either -- just a poll(..) implementation.

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.
