Subject: [PATCH] memory: Add IOMMU_ATTR_MSI_TRANSLATE IOMMU memory region
|
||
|
|
attribute
|
||
|
|
|
||
|
|
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.
