A Linaro developer has proposed adding DMA-BUF
support to the Wayland protocol itself.
Benjamin Gaignard wrote in a mailing list message today, "This protocol is widely derivated of wl_drm protocol
but without unneeded function like flink or authentification. It allow to use a dmabuf file descriptor in a wayland protocol which could be useful in case we don't have (or can't use) Mesa EGL."
The announcement along with the 500+ line protocol patch can be found on Wayland-devel
