[RFC v6 20/24] hw/arm/smmuv3: Fill the IOTLBEntry arch_id on NH_VA invalidation
Posted by Eric Auger 5 years, 10 months ago
When the guest invalidates one S1 entry, it passes the asid.
When propagating this invalidation downto the host, the asid
information also must be passed. So let's fill the arch_id field
introduced for that purpose.
