Hi,
at the moment I'm playing a bit around with the directfb, and I wrote a
small test case to flip two buffers alternating on the screen.
I'm doing like this:
fill the buffer...
primary->Lock(primary, DSLF_WRITE, (void**)(&dst), &rowstride )
int i;
int j;
//copy the whole buffer
for (i=0;i<h;i++){
for(j=0;j<w;j++){
*dst=*p;
p++;
dst++;
}
}
primary->Unlock (primary);
primary->Flip(primary, NULL, DSFLIP_WAITFORSYNC);
On a System using Via unichrome driver that works fine, on a system with
a Intel 855GME Chipset with Integrated Graphic Controller using the i830
or i810
driver, I can't see anything on the screen at all...any ideas? Does the
Driver support flip operations?
Thanks in advance
Kind regards
Alex
