I would like that. I've thought about it before. The one problem I
couldn't figure out is, where to set the accessed and dirty bits for the
pages. Now we do it when we unpin. If we don't pin the pages in the
first place, we don't have a good place for this.
Our hardware doesn't give us notifications or accessed/dirty bits, so we
have to assume the worst case that the pages are continuously
accessed/dirty.
I'd appreciate any advice how to handle that. (Sorry, I realize this is
going a bit off topic.) A pointer to a document or source code would be
great. :)
Thanks,
Felix
