NODEV for "head doesn't exist" and INVAL for "head doesn't support dmabuf/region/..." ? > Are the heads guaranteed to be contiguous (the > first -ENODEV is the end of possible heads)? Yes, I think the valid heads should be contignous. The guest might still only use a non-contignous subset of the available heads though. cheers, Gerd _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
