Instead of adding 'rte_thread_is_intr()' checks, can't you make sure all interrupts handled in control tread? And can you please provide a stack trace in commit log, to describe the issue better? > Cc: stable@dpdk.org > > Signed-off-by: Kaiwen Deng > --- > Changes since v2: > - Add to poll the response for VIRTCHNL_OP_GET_STATS. > > Changes since v1: > - Add lock to avoid race condition. > --- > --- > drivers/net/bonding/rte_eth_bond_pmd.c | 7 ++- > drivers/net/iavf/iavf_ethdev.c | 5 +- > drivers/net/iavf/iavf_vchnl.c | 71 ++++++++++++++++++-------- > 3 files changed, 58 insertions(+), 25 deletions(-) > > diff --git a/drivers/net/bonding/rte_eth_bond_pmd.c b/drivers/net/bonding/rte_eth_bond_pmd.c > index f0c4f7d26b..edce621496 100644 > --- a/drivers/net/bonding/rte_eth_bond_pmd.c > +++ b/drivers/net/bonding/rte_eth_bond_pmd.c > @@ -894,6 +894,7 @@ bond_ethdev_update_tlb_slave_cb(void *arg) > uint8_t update_stats = 0; > uint16_t slave_id; > uint16_t i; > + int ret; > > internals->slave_update_idx++; > > @@ -903,7 +904,10 @@ bond_ethdev_update_tlb_slave_cb(void *arg) > > for (i = 0; i < internals->active_slave_count; i++) { > slave_id = internals->active_slaves[i]; > - rte_eth_stats_get(slave_id, &slave_stats); > + ret = rte_eth_stats_get(slave_id, &slave_stats); > + if (ret) > + goto OUT; > + > tx_bytes = slave_stats.obytes - tlb_last_obytets[slave_id]; > bandwidth_left(slave_id, tx_bytes, > internals->slave_update_idx, &bwg_array[i]); > @@ -922,6 +926,7 @@ bond_ethdev_update_tlb_slave_cb(void *arg) > for (i = 0; i < slave_count; i++) > internals->tlb_slaves_order[i] = bwg_array[i].slave; > > +OUT: > rte_eal_alarm_set(REORDER_PERIOD_MS * 1000, bond_ethdev_update_tlb_slave_cb, > (struct bond_dev_private *)internals); > } > diff --git a/drivers/net/iavf/iavf_ethdev.c b/drivers/net/iavf/iavf_ethdev.c > index 3196210f2c..d6e1f1a7f4 100644 > --- a/drivers/net/iavf/iavf_ethdev.c > +++ b/drivers/net/iavf/iavf_ethdev.c > @@ -2607,6 +2607,9 @@ iavf_dev_init(struct rte_eth_dev *eth_dev) > adapter->dev_data = eth_dev->data; > adapter->stopped = 1; > > + if (iavf_dev_event_handler_init()) > + goto init_vf_err; > + > if (iavf_init_vf(eth_dev) != 0) { > PMD_INIT_LOG(ERR, "Init vf failed"); > return -1; > @@ -2634,8 +2637,6 @@ iavf_dev_init(struct rte_eth_dev *eth_dev) > rte_ether_addr_copy((struct rte_ether_addr *)hw->mac.addr, > ð_dev->data->mac_addrs[0]); > > - if (iavf_dev_event_handler_init()) > - goto init_vf_err; > > if (vf->vf_res->vf_cap_flags & VIRTCHNL_VF_OFFLOAD_WB_ON_ITR) { > /* register callback func to eal lib */ > diff --git a/drivers/net/iavf/iavf_vchnl.c b/drivers/net/iavf/iavf_vchnl.c > index 9adaadb173..aeffb07cca 100644 > --- a/drivers/net/iavf/iavf_vchnl.c > +++ b/drivers/net/iavf/iavf_vchnl.c > @@ -256,6 +256,7 @@ iavf_read_msg_from_pf(struct iavf_adapter *adapter, uint16_t buf_len, > vf->link_speed = iavf_convert_link_speed(speed); > } > iavf_dev_link_update(vf->eth_dev, 0); > + iavf_dev_event_post(vf->eth_dev, RTE_ETH_EVENT_INTR_LSC, NULL, 0); > PMD_DRV_LOG(INFO, "Link status update:%s", > vf->link_up ?
