- * 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.
- */
-
-/*
- * If we pickup an old version of drm.h which doesn't include drm_mode.h
- * we should redefine defines. This is so that builds doesn't breaks with
- * new libdrm on old kernels.
