From: Thomas Huth <[email protected]>
When trying to plug a PCI device to a Sparc64 machine, you currently
have to specify the right bus ("bus=pciB"), otherwise you get this error:
$ qemu-system-sparc64 -device virtio-scsi-pci
qemu-system-sparc64: -device virtio-scsi-pci: PCI: no slot/function
available for virtio-scsi-pci, all in use or reserved
This is quite annoying for the unexperienced users, and it also breaks
e.g. the iotests ("make check-block") when running with qemu-system-sparc64.
Mark the non-usable PCI busses as full now, so that QEMU can automatically
plug new PCI devices to the right "pciB" bus.

Note: Only lightly tested, it seems to work fine for me at a first glance,
but maybe I missed something...
