Subject: [PATCH 0/8] Miscellaneous x86 emulator fixes
Date: Tue, 9 Feb 2010 16:13:56 +0200 [thread overview]
Message-ID: <1265724844-11112-1-git-send-email-gleb@redhat.com> (raw)
X86 emulator fails to do permission/correctness checking like
real CPU does for some instruction. This patch series fixes some
of those discrepancies.
Gleb Natapov (8):
KVM: Add group8 instruction decoding.
KVM: Add group9 instruction decoding.
KVM: Add Virtual-8086 mode of emulation.
KVM: fix memory access during x86 emulation.
KVM: Check IOPL level during io instruction emulation.
KVM: Fix popf emulation.
KVM: Check CPL level during privilege instruction emulation.
KVM: Add LOCK prefix validity checking.
