Hi guys,
First Ros, I've looked at everything you've done and it looks really
good. I should be able to take what you've done and port it quite easily.
Was just thinking a bit now about the framebuffer concept in general.
So, in Linux, the video memory is mapped into the process address apce? What
about protection? The user process can clobber any part of the
frame buffer in addition to working with the part its responsible
for. This might be ok if the application is being granted the entire
screen, like for a game or something. For a windowing system, its not
as appealing. Roadrunner/pk is going to have the same problem as Linux.
Later,
FM
