v5:
In interest of getting reviewed patches in sonner, last two patches
dropped for a later series.
Permute patch order of 2 and 3 (this is what the v4 series should
have had).
v4:
Drop some details from narration to provide better focus.
(suggested/requested by Chris Wilson)
Spelling and grammar fixes.
(errors caught by Tvrtko Ursuli)
Move "at the bottom" details to part of documentation in
i915_gem_execbuffer.c.
(suggested by Chris Wilson)
Place additional documentation of intel_engine_cs function
pointers to inlined in struct.
Fix documentation error about lazy creation of intel_ringbuffer
and backing store in intel_lrc.c.
(Caught by Chris Wilson)
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 (3):

narration
i915.rst: add link to documentation in i915_gem_execbuffer.c
