now i have a question:

i know ppc is big_endian and pci bus is little_endian.i made a graphics pci card use big_endian.

when i use graphics card to show QT 's picture through VGA ,the color is not what i wanted, it's inversed ,others are in right position.

here below is what i want :

#################################################

0..................7  8............15 16..............24 25.................31

         B                    G                   R                TRANS

now it is this:

#################################################

0..................7  8............15 16..............24 25.................31

      TRANS               R                   G                   B

#################################################

 

through mmap, the ppc display the screen color through direct pci bus control ,how can i change it?? 

change kernel?? (i don't know where to change)

or change others??
