Hi Nicolas,
I'm detaching this thread from our V4L2 stateless decoding spec since it has drifted off and would certainly be interesting to DRM folks as well!
For context: I was initially talking about writing up support for the Allwinner 2D engine as a DRM render driver, where I'd like to be able to batch jobs that affect the same destination buffer to only signal the out fence once when the batch is done. We have a similar issue in v4l2 where we'd like the destination buffer for a set of requests (each covering one H264 slice) to be marked as done once the set was decoded.
Out of curiosity, what area did you find a 2D blitter useful for?
Best regards, Tomasz
