We wish that the scheduler emit the context modification commands prior to enabling the oa_config, for which we must explicitly inform it of the ordering constraints. This is especially important as we now wait for the final oa_config setup to be completed and as this wait may be on a distinct context to the state modifications, we need that command packet to be always last in the queue. We borrow the i915_active for its ability to track multiple timelines and the last dma_fence on each; a flexible dma_resv. Keeping track of each dma_fence is important for us so that we can efficiently schedule the requests and reprioritise as required.

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.
