Hello list. How I can access the video memory directly from user space? I tried to map the framebuffer (/dev/fb0) using mmap() and ioctl(), but I have not been successful. Really I want to make a copy of the contents of video memory and save it as an image. have any suggestions?
Hi, probably not the brightest idea, but have check and try to read (carefully) these memory area, such as: $ cat /proc/iomem | grep -i video 000a0000-000bffff : Video RAM area 000c0000-000c7fff : Video ROM -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
