2023-03-31	iommu/sva: Stop using ioasid_set for SVA	Jason Gunthorpe	1	-2/+0
	Instead SVA drivers can use a simple global IDA to allocate PASIDs for each mm_struct. Future work would be to allow drivers using the SVA APIs to reserve global PASIDs from this IDA for their internal use, eg with the DMA API PASID support.

2023-03-31	iommu/sva: Remove PASID to mm lookup function	Jacob Pan	1	-1/+0
	There is no user of iommu_sva_find() function, remove it so that PASID allocator can be a simple IDA. Device drivers are expected to store and keep track of their own PASID metadata.

2022-11-03	iommu: Rename iommu-sva-lib.{c,h}	Lu Baolu	1	-0/+75
	Rename iommu-sva-lib.c[h] to iommu-sva.c[h] as it contains all code for SVA implementation in iommu core.
