I am working on SR-IOV support for a new adapter which has shared resources between the PF and VFs and requires an out-of-band (outside the adapter) communication mechanism to manage those resources. I have been looking at RPMSG as a mechanism to communicate between the driver on a guest (VM) and the driver on the host OS (which "owns" the resources). It appears to me that virtio is intended for communication between guests and host, and RPMSG over virtio is what I want to use. Can anyone confirm that RPMSG is capable of doing what we need? If so, I'll need some help figuring out how to use that from kernel device drivers (I've not been able to find any examples of doing the service/device side). If not, is there some other facility that is better suited? Thanks, Doug External recipient
