Sorry for being unclear. What I meant is not replacing vDPA with the
vhost(bus) you proposed but the possibility of replacing virtio-pci-epf
with vDPA in:
My question is basically for the part of virtio_pci_epf_send_command(),
so it looks to me you have a vendor specific API to replace the
virtio-pci layout of the BAR:
+static int virtio_pci_epf_send_command(struct virtio_pci_device *vp_dev,
+??? ??? ??? ??? ?????? u32 command)
+{
+??? struct virtio_pci_epf *pci_epf;
+??? void __iomem *ioaddr;
+??? ktime_t timeout...
