QEMU currently aborts if you try to use the device at the command
line:
$ ppc64-softmmu/qemu-system-ppc64 -S -machine prep -device pc87312
Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:222:
qemu-system-ppc64: -device pc87312: Device 'parallel0' is in use
Aborted (core dumped)
It uses parallel_hds in its realize function, so I can not be
instantiated by the user again.
Signed-off-by: Thomas Huth <th...@redhat.com>
Reviewed-by: Hervé Poussineau <hpous...@reactos.org>
However, a better solution would probably to not directly use parallel_hds[0],
but to add some Chardev properties to the device, and to fill them in the
mainboard code.
This is noted as a "Future incompatible change" in changelog since 2.8
