[PATCH] Add wl_dmabuf protocol
benjamin.gaignard at linaro.org
benjamin.gaignard at linaro.org
Thu Dec 5 09:36:38 PST 2013
From: Benjamin Gaignard <benjamin.gaignard at linaro.org>
It allow to use a dmabuf file descriptor in a wayland protocol.
To make as generic as possible it is up to the server to call
wl_dmabuf_send_format() and/or wl_dmabuf_send_capabilities() to signal
it capabilities.
