I am not sure what do you mean here. INS read ahead and MMIO read cache are
different beasts. Former is needed to speed-up string pio reads, later
(not yet implemented) is needed to reread previous MMIO read results in
case instruction emulation is restarted due to need to exit to userspace.
MMIO read cache need to be invalidated on each iteration of string
instruction.
Instructions with multiple reads or writes need an mmio read/write
buffer that can be replayed on re-execution.
buffer != cache! A cache can be dropped (perhaps after flushing it to a
backing store), but a buffer in general cannot.
