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