Pull intel iommu updates from David Woodhouse: "This adds "Shared Virtual Memory" (aka PASID support) for the Intel IOMMU. This allows devices to do DMA using process address space, translated through the normal CPU page tables for the relevant mm. With corresponding support added to the i915 driver, this has been tested with the graphics device on Skylake. We don't have the required TLP support in our PCIe root ports for supporting discrete devices yet, so it's only integrated devices that can do it so far" * git://git.infradead.org/intel-iommu: (23 commits) iommu/vt-d: Fix rwxp flags in SVM device fault callback iommu/vt-d: Expose struct svm_dev_ops without CONFIG_INTEL_IOMMU_SVM iommu/vt-d: Clean up pasid_enabled() and ecs_enabled() dependencies iommu/vt-d: Handle Caching Mode implementations of SVM iommu/vt-d: Fix SVM IOTLB flush handling iommu/vt-d: Use dev_err(..) in intel_svm_device_to_iommu(..) iommu/vt-d: fix a loop in prq_event_thread() iommu/vt-d: Fix IOTLB flushing for global pages iommu/vt-d: Fix address shifting in page request handler iommu/vt-d: shift wrapping bug in prq_event_thread() iommu/vt-d: Fix NULL pointer dereference in page request error case iommu/vt-d: Implement SVM_FLAG_SUPERVISOR_MODE for kernel access iommu/vt-d: Implement SVM_FLAG_PRIVATE_PASID to allocate unique PASIDs iommu/vt-d: Add callback to device driver on page faults iommu/vt-d: Implement page request handling iommu/vt-d: Generalise DMAR MSI setup to allow for page request events iommu/vt-d: Implement deferred invalidate for SVM iommu/vt-d: Add basic SVM PASID support iommu/vt-d: Always enable PASID/PRI PCI capabilities before ATS iommu/vt-d: Add initial support for PASID tables ... |
