I don't really have work that I can push forward in parallel. My point was that the modifications to the V4L2 API and the implementation in videobuf2 are two separate tasks that should be pushed forward in parallel (extending the V4L2 API takes quite a lot of time in my experience, our developers like nit- picking on the mailing list when they review the documentation - which I consider as a good thing, just for the record).
Laurent, is there an action here to kick off the discussion of the V4L2 API changes (which I don't understand current status of very well)?
Patches have already been posted to the linux-media mailing list. They miss documentation though, I think it would help getting reviewers if we documented the API. Tomasz, you mentioned that you would work on that for the next version, have you had time to update the patch with the Documentation/DocBook/media/v4l changes ?
Hi Laurent, The documentation patches should be split into importer and exporter parts. Due to the problems with dma_get_pages (or other form of DMA cookie extractor) the exporter part is probably going to be postponed until DMA-mapping-redesign reaches a steady state.
I haven't focused on documentation part yet but I will try to prepare at least a sketch of documentation for DMABUF importer. Quite probably, it will be posted next week.
