An experimental (hence the 'z' prefix) linux_dmabuf Wayland protocol extension for creating dmabuf-based wl_buffers in a generic manner. This does not include proper dmabuf metadata negotiation because there is no way to communicate all dmabuf constraints from the compositor to a client before-hand. The client has to create a wl_buffer wrapping one or more dmabuf buffers and then listen at the feedback object returned to know if the operation was successful. RFCv1 changes (after a first draft without code): - some renames of interfaces and argument, no semantic changes - added destructor protocol to dmabuf_batch - added feedback interface for buffer creation v2 changes: - use drm_fourcc.h as authoritative source for format codes - add support for the 64-bit layout qualifier and y-inverted dmabufs - simplify the 'add' request (no need to preserve fd numerical id) - add explicit plane index in the 'add' request - integrate the 'feedback' object events to the batch interface - rename 'create_buffer' to 'create' and move it into the batch interface - add requirements needed from the graphics stack and clients - improve existing errors and add batch error codes - removed error codes from the global interface - improve documentation for arguments, enums, etc. - rename dmabuf_batch to zlinux_buffer_params - The y-inverted property makes more sense as a whole buffer property. Y-flipping individual planes of the same buffer object is hardly useful. The y-invert is also converted into a flag, so we may add more flags later. - add flags for interlaced buffer content v3 changes: - Apply Daniel Vetter's comments about wording on coherency.
