[PATCH v3 07/16] iommu/vt-d: assign PFSID in device TLB invalidation

2017-11-17 Thread Jacob Pan
When SRIOV VF device IOTLB is invalidated, we need to provide the PF source SID such that IOMMU hardware can gauge the depth of invalidation queue which is shared among VFs. This is needed when device invalidation throttle (DIT) capability is supported. Signed-off-by: Jacob Pan
