[PATCH v5 06/23] iommu/vt-d: add definitions for PFSID

2018-05-11 Thread Jacob Pan
When SRIOV VF device IOTLB is invalidated, we need to provide the PF source ID 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. This patch adds bit definitions for checking
