Subject: [PATCH] hw/arm/smmu-common: Allow domain invalidation for
|
|
NH_ALL/NSNH_ALL
|
|
|
|
NH_ALL/NSNH_ALL corresponds to a domain granularity invalidation,
|
|
ie. all the notifier range gets invalidation, whatever the ASID.
|
|
So let's set the granularity to IOMMU_INV_GRAN_DOMAIN to allow
|
|
the consumer to benefit from the info if it can.
