Typedefs | |
| typedef void(* | doca_devemu_virtio_dev_event_reset_handler_cb_t) (struct doca_devemu_virtio_dev *virtio_dev, union doca_data event_user_data) |
| Function to be executed on Virtio device reset. The event handler will enable users to quiesce, flush and reset the necessary resources associated with the emulated Virtio device. Upon event, all PCI I/O transactions to/from the host memory are disabled. Additionally, the user should flush all the outstanding resources associated with the emulated Virtio device, which were initially owned by the Virtio device and moved the the ownership of the user. After flushing all the outstanding resources, the user should call doca_devemu_virtio_dev_reset_complete(). More... | |

| Function to be executed upon finishing asynchronous population of Virtio queue statistics list. More... | |
