[PATCH for 7.2 0/2] s390x/s390-virtio-ccw:

Posted by Cédric Le Goater 1 year, 5 months ago

Hello,

This series removes the redundant "zpcii-disable" machine property and
and introduces a GlobalProperty compat array to maintain the same
behaviour on older machines.

Thanks,

C.

Thanks Cedric.

For the series:
Reviewed-by: Matthew Rosato <mjrosato@linux.ibm.com>

Also did a quick test on top of
https://gitlab.com/thuth/qemu.git tags/pull-request-2022-11-06

to verify that zPCI interpretation/forwarding is available as expected with machine 7.2 and off by default in 7.1 and older.
