[Xen-devel] Shadow pagetable code changes since 3.0.2
I don't know if anyone's tried this already or even knows about this, but
I'm trying to apply the Potemkin patch to the new Xen 3.1.0 source code.
The original Potemkin patch by Michael Vrable et al.
(www.cs.ucsd.edu/~savage/papers/Sosp05.pdf) implements delta
virtualization (copy-on-write fork for guest domain memory) as an
extension to Xen's translated shadow mode. Download is available here:
I noticed that the shadow pagetable code has went through some serious
design change since 3.0.2, and I couldn't find a good documentation that
explains how the old code maps to the new code.
Can anyone please explain the exact nature of the change - how the new
functions replace the old ones?
