Then, it calls the\n“rte_eth_dev_event_handler_install” API to install the device\nevent handler for ethdev. When the eal device event be detected,\nit calls the ethdev callback to process it. If the event is the\nhotplug-out event, it will trigger the “RTE_ETH_EVENT_INTR_RMV”\nevent into the ethdev callback to allow the application's callback\nto process hotplug for this ethdev.\n\nSigned-off-by: Jeff Guo <jia.guo@intel.com>\nAcked-by: Qi Zhang <qi.z.zhang@intel.com>\n---\nv6->v5:\nrefine commit log\n---\n drivers/net/i40e/i40e_ethdev.c | 8 +++++++-\n 1 file changed, 7 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/i40e/i40e_ethdev.c b/drivers/net/i40e/i40e_ethdev.c\nindex 85a6a86..bd9b3ce 100644\n--- a/drivers/net/i40e/i40e_ethdev.c\n+++ b/drivers/net/i40e/i40e_ethdev.c\n@@ -697,7 +697,7 @@ static int eth_i40e_pci_remove(struct rte_pci_device *pci_dev)\n static struct rte_pci_driver rte_i40e_pmd = {\n \t.id_table = pci_id_i40e_map,\n \t.drv_flags = RTE_PCI_DRV_NEED_MAPPING | RTE_PCI_DRV_INTR_LSC |\n-\t\t RTE_PCI_DRV_IOVA_AS_VA,\n+\t\t RTE_PCI_DRV_IOVA_AS_VA | RTE_PCI_DRV_INTR_RMV,\n \t.probe = eth_i40e_pci_probe,\n \t.remove = eth_i40e_pci_remove,\n };\n@@ -1466,6 +1466,9 @@ eth_i40e_dev_init(struct rte_eth_dev *dev, void *init_params __rte_unused)\n \trte_intr_callback_register(intr_handle,\n \t\t\t\t i40e_dev_interrupt_handler, dev);\n \n+\t/* install the dev event handler for ethdev. */\n+\trte_eth_dev_event_handler_install(dev);\n+\n \t/* configure and enable device interrupt */\n \ti40e_pf_config_irq0(hw, TRUE);\n \ti40e_pf_enable_irq0(hw);\n@@ -1697,6 +1700,9 @@ eth_i40e_dev_uninit(struct rte_eth_dev *dev)\n \t/* Remove all Traffic Manager configuration */\n \ti40e_tm_conf_uninit(dev);\n \n+\t/* uninstall the dev event handler for ethdev. */\n+\trte_eth_dev_event_handler_uninstall(dev);\n+\n \treturn 0;\n }\n \n", "prefixes": [ "v6", "3/4" ] }
