  39  * This is the interface for modesetting for drm.
  40  *
  41  * In order to use this interface you must include either <stdint.h> or another
  42  * header defining uint32_t, int32_t and uint16_t.
  43  *
  44  * It aims to provide a randr1.2 compatible interface for modesettings in the
  45  * kernel, the interface is also ment to be used by libraries like EGL.
  46  *
  47  * More information can be found in randrproto.txt which can be found here:
  48  * http://gitweb.freedesktop.org/?p=xorg/proto/randrproto.git
  49  *
  50  * There are some major diffrences to be noted. Unlike the randr1.2 proto you
  51  * need to create the memory object of the framebuffer yourself with the ttm
  52  * buffer object interface. This object needs to be pinned.
  53  */
  54
  55 /*
  56  * If we pickup an old version of drm.h which doesn't include drm_mode.h
  57  * we should redefine defines. This is so that builds doesn't breaks with
  58  * new libdrm on old kernels.
