* expected / delivered in machine endiannes by this
* driver .
* 2 ) Video memory . The data is copied 1 : 1 . There is
* no swapping . Ever . This means for userland that
* the data has to be prepared properly . ( Hint :
* think graphics data format , command queue ,
* hardware cursor . )
* 3 ) MMIO . Data is copied 1 : 1 . MMIO must be swapped
* properly by userland .
