Hi,
I changed a little bit the vfb module to be used as a frame buffer in
memory. I would like to use the mmap over the virtual framebuffer. I
added a few line:
I allocated the buffer using
videomemory=(void *)__get_free_pages(GFP_KERNEL,
get_order(PAGE_ALIGN(videomemorysize)));
and fixed the framebuffer info structure:
vfb_fix.smem_start = virt_to_phys(videomemory);
vfb_fix.smem_len = videomemorysize;
What is the virtual frame buffer meant for?
Regards Michael
