Firstly it\nset the flags RTE_PCI_DRV_INTR_RMV in drv_flags to announce the hotplug\nability, and then use rte_eth_dev_event_handler_install to install\nthe hotplug event handler for ethdev. When eal detect the hotplug event,\nit will call the ethdev callback to process it. If the event is hotplug\nremoval, it will trigger the RTE_ETH_EVENT_INTR_RMV event into ethdev\ncallback to let app process the hotplug for this ethdev.\n\nThis is an example for other driver, that if any driver support hotplug\nfeature could be use this way to install hotplug handler.\n\nSigned-off-by: Jeff Guo <jia.guo@intel.com>\n---\nv4->v3:\nchange to use eal device event handler install api\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 13c5d32..8fccf04 100644\n--- a/drivers/net/i40e/i40e_ethdev.c\n+++ b/drivers/net/i40e/i40e_ethdev.c\n@@ -688,7 +688,7 @@ 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@@ -1442,6 +1442,9 @@ 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@@ -1674,6 +1677,9 @@ 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": [ "v4", "3/4" ] }
