I'm just curious, from where do you queue the writeback job if you don't have a connector->atomic_commit() hook implemented? AFAICT, the encoder->enable() method is only called when the encoder is being enabled, and not every time you update the FB_ID prop of the writeback connector.

I'll update the code and the doc in a separate commit. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
