Sure, Thanks Jason, I will check this part.

These code are all tested in vp-vdpa (support configure interrupt)
vdpa_sim (not support configure interrupt)


Cindy Lu (4):
   virtio:add support in configure interrupt
   virtio-pci:add support for configure interrupt



If possible, I would like to add the MMIO support for this.

One great advantage of vDPA is that it can avoid to expose a PCI device 
for guest.


Thanks

[PATCH v1 0/4] vhost-vdpa: add support for configure interrupt 

2021-01-13 Thread Cindy Lu 
Add configure interrupt support in vdpa_vhost. qemu will use the irqfd
process to support this feature.

These code are all tested in vp-vdpa (support configure interrupt)
vdpa_sim (not support configure interrupt)


Cindy Lu (4):
  virtio:add support in configure interrupt
  virtio-pci:add support for configure interrupt
  vhost_net:enable configure interrupt when vhost_net start
  vhost-vdpa:add callback function for configure interrupt
