Subject: [PATCH 0/2] Emulate MMX MOVQ
Date: Wed, 21 Mar 2012 20:40:20 +0200	[thread overview]
Message-ID: <1332355222-30508-1-git-send-email-avi@redhat.com> (raw)

This patchset emulates two instructions:

  MOVQ mm, mm/m64
  MOVQ mm/m64, mm

Needed by https://bugzilla.kernel.org/show_bug.cgi?id=42779. However it seems
to fail sometimes in my unit test, generating a math fault at the fwait
instruction (which is duly trapped).  Hints appreciated.

  KVM: x86 emulator: MMX support
  KVM: x86 emulator: implement MMX MOVQ (opcodes 0f 6f, 0f 7f)
