Public bug reported:
---Problem Description---
QEMU 5.2.0 (Ubuntu 21.04) does not have the virtio-9p-ccw device.
Following patch should be used at
https://lists.nongnu.org/archive/html/qemu-devel/2021-02/msg05793.html.
This should be back-ported.
---Steps to Reproduce---
Build QEMU from https://download.qemu.org/qemu-5.2.0.tar.xz and try
qemu-system-s390x -device virtio-9p-ccw
Userspace tool common name: QEMU
The userspace tool has the following bit modes: 64-bit
Userspace rpm: qemu-system-s390x
Userspace tool obtained from project website: 5.2.0
Commit 2c44220d05 ("meson: convert hw/arch*"), which migrated the old
Makefile.objs to meson.build accidentally excluded virtio-ccw-9p.c and
thus the virtio-9p-ccw device from the build (and potentially also
included the file virtio-ccw-blk.c twice in the source set). And since
CONFIG_VIRTFS can't be used the way it was used here (see commit
2c9dce0196 ("meson: do not use CONFIG_VIRTFS")), the preconditions have
to be written differently.
Let's fix this!
