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.
