Hi,
Im trying to figure out how (on, say, x86), qemu (1.3, git) knows when
the guest has accessed a page - in particular, on a framebuffer.
It looks like its done via dirty page logs, which are maintained by the
host kernel, so probably this is a kernel question, more than a qemu one.
Is this the case? if so, where do the bits in the dirty bitmap get set?
I cant find anything in the kernel that seems to do much with it, other
than to copy the bitmap to userspace.
