* 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.
