From: Kevin Rogovin <kevin.rogovin@xxxxxxxxx>
Note: I want to make a one or two follow-up series that provide
narration and potentially additional documentation for GUC submission
and the breadcrumbs.
v3:
More documentation: emphasize that handling of batchbuffer
requests creates a request struct that is added to the
dependency tree and that the inform to the hardware that
there is new data on a ringbuffer is deferred until dependencies
are satsified.
Break patch into more digestable chunks.
v2:
More documentation: intel_ringbuffer, sequence number.
Expose to i915.rst existing documentation
Call out GEM_EXECBUFFER as deprecated.
Place code detailed documentation in source files.
Call out INTEL_EXEC_RENDER.
Reorder text to make it more readable.
Refer to Command Buffer Parser instead of Batchbuffer Parser.
(suggested by Joonas Lahtinen)
Kevin Rogovin (6):
i915.rst: Narration overview on GEM + minor reorder to improve
narration
i915.rst: rename section Batchbuffer Parsing to Command Buffer Parsing
i915: add documentation of what happens at the bottom of submitting a
batchbuffer
i915: add documentation for a bit on batchbuffer submission backend
i915: add doc for synchronization
i915.rst: narration for batchbuffer submission + links to source code
doc entries on the subject
