I would like to remind that this is not about the graphic stack. Again, DRM to
DRM is a tiny little aspect here. This bug is about a proposal on how to
exchange unknown pixel formats across drivers, what information need to be
carried and were (caps, meta, etc). Its also about how to avoid the traps that
will make the pipeline fail in an unrecoverable way, specially in cases it
worked before using a slower path.
