Subject: [PATCH v3 0/5] KVM: x86: improve reexecute_instruction
Date: Sat, 15 Dec 2012 14:57:38 +0800 [thread overview]
Message-ID: <50CC1F62.4050701@linux.vnet.ibm.com> (raw)
Changlog:
- do not change pte access for mmio access
- a new bug is exposed that Dirty bit is not tracked if CR0.WP = 0
- cache something on page fault path and use them to detect unhandleable
instruction, suggested by Marcelo
I will add the two testcase for unhandleable instruction after figure
out a way to notify the unemulationable error to guest
