I want to determine the amount of screen activity taking place on VGA monitor/ Screen for different applications (eg. playing vlc video, normal typing.)
When I do not start the X server, I can easily determine the screen activity by counting the number of pages accessed in the region 0xA0000 - 0xBffff (This is the VGA Monitor region in boot screen).
However when I start the X Server, A diffrent set of pages are hit. Could anyone please explain how the VGA Monitor works in QEMU? Or if someone could suggest an alternate solution to determine amount of screen activity while playing diffrent applications?
[NOTE : I have already checked for the region where X server pages are mapped using cat /proc/iomem. But pages are not getting written to the "possible" X server mmapped region.]
