From 876d18c962f0ead31d8458cd7ac19178be78455c Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 19 Mar 2021 12:22:48 -0400 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.
