And, as Andrew suggested last time around, could you perhaps push this
fancy new idea into the FB layer so that more drivers can make us of it?
I would like to do that very much. I have some ideas how it could work
for devices that support clean partial updates by tracking touched
pages. But I wonder if it is too early to try to abstract this out.
James, Geert, what do you think?
for the real framebuffer updates when there's more than a couple of pages
that have been touched, which would also be nice to have. There's more
than a few drivers that could take advantage of that.
