46 * This is the interface for modesetting for drm.
47 *
48 * In order to use this interface you must include either <stdint.h> or another
49 * header defining uint32_t, int32_t and uint16_t.
50 *
51 * It aims to provide a randr1.2 compatible interface for modesettings in the
52 * kernel, the interface is also ment to be used by libraries like EGL.
53 *
54 * More information can be found in randrproto.txt which can be found here:
55 * http://gitweb.freedesktop.org/?p=xorg/proto/randrproto.git
56 *
57 * There are some major diffrences to be noted. Unlike the randr1.2 proto you
58 * need to create the memory object of the framebuffer yourself with the ttm
59 * buffer object interface. This object needs to be pinned.

63 * If we pickup an old version of drm.h which doesn't include drm_mode.h
