From 7972995b0c346de76fe260ce0fd6bcc8ffab724a Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Thu, 18 Mar 2010 15:20:24 +0200 Subject: KVM: x86 emulator: Move string pio emulation into emulator.c Currently emulation is done outside of emulator so things like doing ins/outs to/from mmio are broken it also makes it hard (if not impossible) to implement single stepping in the future. The implementation in this patch is not efficient since it exits to userspace for each IO while previous implementation did 'ins' in batches. Further patch that implements pio in string read ahead address this problem.
