Just curious, but the 2d blitter have it's own sort of
command-processor, ie. can you feed it a list of different blits in
one batch and then it will process them one after another?
If so, that would make the separate ioctls for SET_CMDLIST on each
blit operation, and then EXEC a bit awkward, and give you a huge # of
ioctls for something like EXA/x11 trying to use the blitter.
Is there some documentation about G2D somewhere that I could read?
Just curious, because I have a chromebook on the way and was wondering
about trying to give x11 a bit help by means of G2D..
