[PATCH 0/1] hw/arm: virt: add GICv2m for the case when ITS is not available

Posted by Mohamed Mediouni 3 months, 3 weeks ago

Client virtualization environments shipping with a GICv3 + GICv2m configuration
without support for emulating an ITS makes this more and more necessary...

Done in a backwards-compatible way without altering the existing device model
for older guests, but wonder if having a separate gicv2m flag is worthwhile.
