PIO for passthrough does not work properly since the permissions are not set, it is not enough to call iopl at init time.
This temporary patch calls iopl for every pio request. A better solution would be have a per thread iopl. An alternative approach would be to use sysfs for pio. In the mean time, if you want to use the vtd branch, then you probably need this patch. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
