Hello,
In the above functions, are the various position
parameters (sx, xx, sy, yy) in
1) display coordinate
2) buffer coordinate
if it's 1, then one must take p->var.{x,y}offset
into account when implementing HW acceleration.
that's what pm3fb assume. it doesn't work
apparently (when using yres_virtual > yres,
i.e. using panning)
if it's 2, as apparently is assumed by fbcon_cfb*,
then one can just ignore the offset. it works
for the non-accelerated pm3fb.
Before I commit my change to fix pm3fb, I'd
like an authoritative answer on the subject.
It just _feels_ wrong to me to use absolute
coordinate.
TIA
