[PATCH 0/2] s390x: ccw: A simple test device for virtio CCW

Hello All,

This series presents a VIRTIO test device which receives data on its
input channel and sends back a simple checksum for the data it received
on its output channel.
The goal is to allow a simple VIRTIO device driver to check the VIRTIO
initialization and various data transfer.

For this I introduced a new device ID for the device and having no
Linux driver but a kvm-unit-test driver, I have the following

Is there another way to advertise new VIRTIO IDs but Linux?
If this QEMU test meet interest, should I write a Linux test program?
