I have emulated a PCI device on Qemu and hooked my sample/simple driver to that virtio device on the guest. I am testing the notification from Guest-Qemu and vice-versa. I am able to notify from Guest to Qemu but Qemu-Guest notification is not happening. As a part of "Kick" routine in my guest driver I could see the notification happening from Guest-Qemu and In the Qemu process as a part of handle output for the emulated device I am simply doing "virtio_notify(vdev, vq)" but I don't see my callback getting called which is already registered as a part of "find_vq" in guest driver's probe. BTW, the emulated device is allocated with "GSI 11" where as for other emulated devices like "virtio-blk" is associated with GSI 10 which I found in "dmesg's". Is this a reason why interrupt is not delivered from Qemu-Guest? Any clues?
