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
