Subject: [PATCH v3 11/11] hw/arm/smmuv3: Advertise SMMUv3.2 range invalidation
Date: Wed,  8 Jul 2020 16:18:56 +0200	[thread overview]
Message-ID: <20200708141856.15776-12-eric.auger@redhat.com> (raw)
In-Reply-To: <20200708141856.15776-1-eric.auger@redhat.com>

Expose the RIL bit so that the guest driver uses range
invalidation. Range invalidation being an SMMU3.2 feature,
let AIDR advertise SMMUv3.2 support.
