This patch introduce a vDPA driver for virtio-pci device. It bridges
the virtio-pci control command to the vDPA bus. This will be used for
developing new features for both software vDPA framework and hardware
vDPA feature.
Compared to vdpa_sim, it has several advantages:
- it's a real device driver which allow us to play with real hardware
features
- type independent instead of networking specific
Note that since virtio specification does not support get/restore
virtqueue state. So we can not use this driver for VM. This can be
addressed by extending the virtio specification.
Consider the driver is mainly for testing and development for vDPA
features, it can only be bound via dynamic ids to make sure it's not
conflict with the drivers like virtio-pci or IFCVF.

which tree is this on top of?
Your vhost.git vhost branch, HEAD is bbea3bcfd1d6 vdpa: fix typos in the
comments for __vdpa_alloc_device()
Do I need to use other branch?
Thanks
No it's ok, I am just wondering why doesn't it apply then.
I found the reason, I generate the patch on another branch whose base
does not existed in the vhost branch. Will repost.
Sorry.
