I suggest the title be: vhost: add log for VHOST_USER_SET_VRING_BASE > > Usually the last avail index and last used index is 0, but for target > device of live migration, the last avail index and last used index is > not 0. So I think some log is helpful. Can simplify to: This patch adds log for vring related info in handling of vhost message VHOST_USER_SET_VRING_BASE, which will be useful in live migration case. > > Signed-off-by: Andy Pei <andy....@intel.com> > --- > lib/vhost/vhost_user.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/lib/vhost/vhost_user.c b/lib/vhost/vhost_user.c > index a781346..3cb13fb 100644 > --- a/lib/vhost/vhost_user.c > +++ b/lib/vhost/vhost_user.c > @@ -973,6 +973,11 @@ > vq->last_avail_idx = msg->payload.state.num; > } > > + VHOST_LOG_CONFIG(INFO, > + "vring base idx:%d last_used_idx:%u last_avail_idx:%u.\n", vring idx:%u Thanks, Chenbo > + msg->payload.state.index, vq->last_used_idx, > + vq->last_avail_idx); > + > return RTE_VHOST_MSG_RESULT_OK; > } > > -- > 1.8.3.1
