48 * This is the interface for modesetting for drm.
50 * In order to use this interface you must include either <stdint.h> or another
51 * header defining uint32_t, int32_t and uint16_t.
53 * It aims to provide a randr1.2 compatible interface for modesettings in the
54 * kernel, the interface is also meant to be used by libraries like EGL.
56 * More information can be found in randrproto.txt which can be found here:
57 * http://gitweb.freedesktop.org/?p=xorg/proto/randrproto.git
59 * There are some major differences to be noted. Unlike the randr1.2 proto you
60 * need to create the memory object of the framebuffer yourself with the ttm
61 * buffer object interface. This object needs to be pinned.
65 * If we pickup an old version of drm.h which doesn't include drm_mode.h
66 * we should redefine defines. This is so that builds doesn't breaks with
67 * new libdrm on old kernels.
