Sorry for the late question, but I missed your first version. Is there a way to change that code to use virtio instead of PCI? That would allow us to use this driver on s390 and maybe other virtio transports.

Forgive my s390 ignorance, but is there a device interface in s390 that
can export memory and support interrupts? I'm not opposed to virtio,
but I like the simplicity of the PCI approach as well as having the
memory that is shared external to any particular VM. The current
approach is using a shared memory object on the host as the shared
memory the VMs share.
