2008-11-24vga optimization (Glauber Costa)aliguori
Hypervisors like KVM perform badly while doing mmio on a loop, because it'll generate an exit on each access. This is the case with VGA, which results in very bad performance. In this patch, we map the linear frame buffer as RAM, make sure it has dirty region tracking enabled, and then just let the region to be written.
