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.]
Regards,
