Add some trace points for IOTLB translation for vhost. After vhost-user is setup, the only IO path that QEMU will participate should be the IOMMU translation, so it'll be good we can track this with explicit timestamps when needed to see how long time we take to do the translation, and whether there's anything stuck inside. It might be useful for triaging vhost-user problems. Signed-off-by: Peter Xu <peterx@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
