[RFC v9 08/29] memory: Add IOMMU_ATTR_MSI_TRANSLATE IOMMU memory region attribute |
Date: |
Sun, 11 Apr 2021 14:08:51 +0200 |
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.
