Hi guys,
With the generic vDPA device, QEMU won't need to touch the device
types any more, such like vfio.
We can use the generic vDPA device as follow:
-device vhost-vdpa-device-pci,vdpa-dev=/dev/vhost-vdpa-X
I've done some simple tests on Huawei's offloading card (net, 0.95)
and vdpa_sim_blk (1.0);
The whole seems almost okay, I left you some comments, but for the next
version maybe it's better to reorganize the series differently.
Instead of adding vdpa-dev and vdpa-dev-pci incrementally, with stub
functions and untestable parts, I would make a patch that adds vdpa-dev
in full and then one that adds vdpa-dev-pci.
The first 2 patches on the other hand are okay, maybe patch 2 won't be
needed since I think we will sync the headers after the 7.0 release, but
is better to keep it for now to simplify the review.
Thanks,
Stefano
