We are now able to configure a pipeline directly into a local display
list body. Take advantage of this fact, and create a cacheable body to
store the configuration of the pipeline in the pipeline object.
vsp1_video_pipeline_run() is now the last user of the pipe->dl object.
Convert this function to use the cached pipe->stream_config body and
obtain a local display list reference.
Attach the pipe->stream_config body to the display list when needed
before committing to hardware.
Use a flag 'configured' to know when we should attach our stream_config
to the next outgoing display list to reconfigure the hardware in the
event of our first frame, or the first frame following a suspend/resume
cycle.
Our video DL usage now looks like the below output:
dl->body0 contains our disposable runtime configuration. Max 41.
dl_child->body0 is our partition specific configuration. Max 12.
dl->bodies shows our constant configuration and LUTs.
These two are LUT/CLU:
* dl->bodies[x]->num_entries 256 / max 256
* dl->bodies[x]->num_entries 4914 / max 4914
Which shows that our 'constant' configuration cache is currently
utilised to a maximum of 64 entries.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
