KVM: Coalesced MMIO support
MMIO exits are more expensive in KVM or Xen than in QEMU because theyinvolve, at least, privilege transitions. However, MMIO writeoperations can be effectively batched if those writes do not have sideeffects.
Good examples of this include VGA pixel operations when in a planar...
