Subject: [RFC v8 07/28] memory: Add IOMMU_ATTR_MSI_TRANSLATE IOMMU memory region attribute
Date: Thu, 25 Feb 2021 11:52:12 +0100 [thread overview]
Message-ID: <20210225105233.650545-8-eric.auger@redhat.com> (raw)
In-Reply-To: <20210225105233.650545-1-eric.auger@redhat.com>
We introduce a new IOMMU Memory Region attribute, IOMMU_ATTR_MSI_TRANSLATE
which tells whether the virtual IOMMU translates MSIs. ARM SMMU
will expose this attribute since, as opposed to Intel DMAR, MSIs
are translated as any other DMA requests.
