Cover letter [PATCH 0/3] iommu/vt-d: Global PASID name space
Hi,
This patch series is trying to change the scope of PASID management used in Intel IOMMU driver from per IOMMU to driver global. This is required for some cases where current per-IOMMU PASID name space doesn't work. For an example, one application (associated with one PASID) might talk to two physical devices simultaneously where two devices could reside behind two different IOMMU units.
Best regards,
Lu Baolu
