Hi all,
Until now everything was going fine, while doing some research on DFB,
but currently i encounter a strange situation in memory allocation for
framebuffers. because currently i have allocated videomemory for creating a
surface options but at onestage the memory is full and i get crashed, so i
need to split the memory allocation to share with my system like using
malloc becoz my hardware has enough memory but video memory is limited. but
the strange is that the image when it tries to blit to the surface it takes
more time to blit and also the image is not that clear too. but while using
videoonly option my image is fine. So is there anyother option to allocate
memory to create a surface, i even tried preallocation as follows
void* fbAddr =(void *) calloc(width * height, sizeof(int));
dsc.flags = DSDESC_CAPS|DSDESC_PREALLOCATED|DSDESC_WIDTH |
DSDESC_HEIGHT | DSDESC_PIXELFORMAT;
dsc.caps = DSCAPS_SystemOnly;
dsc.preallocated[0].data=fbAddr;
dsc.preallocated[0].pitch = primary.pitch;
dsc.preallocated[1].data = NULL;
dsc.preallocated[1].pitch = 0;
dsc.width = width;
dsc.height = height;
dsc.pixelformat = DSPF_ARGB;
error = dfb->CreateSurface(dfb, &dsc, &surface);
but still it takes more time to blit/draw to the surface. So please can
anyone help me out to solve this issue, Thanking you for your sharing your
precious time in reading this.
cheers
Kumar
