Hi,
1) Are blit operations (and others) perforemed in blocking style (eg.
call is returned when operation is complete) or in non-blocking style
(operation is put into hw or software queue/fifo and performed later,
when card is not busy)?
I'm blitting a large portion of data I would like to this in
non-blocking style. Eg. let the hardware do blit and processor do
something else.
2) Is using threads together with DirectFB safe? Means more threads will
acess same dfb (and same surfaces) created at programm start
simultaneously.
3) Is blitting from surface in main memory to surface in videomemory hw
accelarated on MGA? (My assumption YES) And is this blit using DMA? (My
assumption NO)
Thanks for Your reply
