Thanks. Looks like the similar fix. Will comment that patch and drop this one if that is merged. > > > -----Original Message----- > > From: Wu, Jingjing <jingjing.wu@intel.com> > > Sent: Thursday, January 7, 2021 4:27 PM > > To: dev@dpdk.org > > Cc: Wu, Jingjing <jingjing.wu@intel.com>; Xing, Beilei > > <beilei.xing@intel.com>; Xia, Chenbo <chenbo.xia@intel.com>; Lu, > > Xiuchun <xiuchun.lu@intel.com> > > Subject: [PATCH v3 5/5] net/iavf: fix vector mapping with queue > > > > Fix the vector mapping with queue by changing the recircle when > > exceeds RX_VEC_START + nb_msix; > > > > Fixes: d6bde6b5eae9 ("net/avf: enable Rx interrupt") > > > > Signed-off-by: Jingjing Wu <jingjing.wu@intel.com> > > --- > > drivers/net/iavf/iavf_ethdev.c | 4 ++-- > > 1 file changed, 2 insertions(+), 2 deletions(-) > > > > diff --git a/drivers/net/iavf/iavf_ethdev.c > > b/drivers/net/iavf/iavf_ethdev.c index 06395f852b..b169b19975 100644 > > --- a/drivers/net/iavf/iavf_ethdev.c > > +++ b/drivers/net/iavf/iavf_ethdev.c > > @@ -570,7 +570,7 @@ static int iavf_config_rx_queues_irqs(struct > > rte_eth_dev *dev, > > /* If Rx interrupt is reuquired, and we can use > > * multi interrupts, then the vec is from 1 > > */ > > - vf->nb_msix = RTE_MIN(vf->vf_res->max_vectors, > > + vf->nb_msix = RTE_MIN(vf->vf_res->max_vectors - > 1, > > intr_handle->nb_efd); > > vf->msix_base = IAVF_RX_VEC_START; > > vec = IAVF_RX_VEC_START; > > @@ -578,7 +578,7 @@ static int iavf_config_rx_queues_irqs(struct > > rte_eth_dev *dev, > > qv_map[i].queue_id = i; > > qv_map[i].vector_id = vec; > > intr_handle->intr_vec[i] = vec++; > > - if (vec >= vf->nb_msix) > > + if (vec >= vf->nb_msix + > IAVF_RX_VEC_START) > > vec = IAVF_RX_VEC_START; > > } > > vf->qv_map = qv_map; > > -- > > 2.21.1
