From adcf33a504de29feb720736051dc32889314c9e6 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 17 Mar 2021 10:56:22 +0100 Subject: [PATCH] s390x: modularize virtio-gpu-ccw Since the virtio-gpu-ccw device depends on the hw-display-virtio-gpu module, which provides the type virtio-gpu-device, packaging the hw-display-virtio-gpu module as a separate package that may or may not be installed along with the qemu package leads to problems. Namely if the hw-display-virtio-gpu is absent, qemu continues to advertise virtio-gpu-ccw, but it aborts not only when one attempts using virtio-gpu-ccw, but also when libvirtd's capability probing tries to instantiate the type to introspect it. Let us thus introduce a module named hw-s390x-virtio-gpu-ccw that is going to provide the virtio-gpu-ccw device. The hw-s390x prefix was chosen because it is not a portable device. With virtio-gpu-ccw built as a module, the correct way to package a modularized qemu is to require that hw-display-virtio-gpu must be installed whenever the module hw-s390x-virtio-gpu-ccw.
