From 4731d4c7a07769cf2926c327177b97bb8c68cafc Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Tue, 23 Sep 2008 13:18:39 -0300 Subject: KVM: MMU: out of sync shadow core Allow guest pagetables to go out of sync. Instead of emulating write accesses to guest pagetables, or unshadowing them, we un-write-protect the page table and allow the guest to modify it at will. We rely on invlpg executions to synchronize individual ptes, and will synchronize the entire pagetable on tlb flushes.
