Subject: question about vdpa_mgmt_dev
Date: Mon, 15 Nov 2021 05:52:24 +0000	[thread overview]
Message-ID: <10b3825413da4a73ac8cdce9eca5e860@baidu.com> (raw)

Hi Experts
	I have read the upstream code about vdpa, and I notice that there is a new struct vdpa_mgmt_dev have been added.
	Every driver implements dev_add() interface, such as mlx5 use mlx5_vdpa_dev_add(). This interface completes the creation of the vdpa device, hardware initialization and system registration. And I found that only netlink will call the dev_add() interface, in vdpa_nl_cmd_dev_add_set_doit(). While the probe() function just register vdpa_mgmt_dev without call dev_add()
	So, my questions are:
	Does it create a vdpa device only through the netlink interface? The system scans the PCI device and does not automatically create the corresponding vdpa device?
	

Thanks
Feng
