• 3715863aa   iommu: export iommu_is_span_boundary helper function ... Browse Code »

  iommu_is_span_boundary is used internally in the IOMMU helper
  (lib/iommu-helper.c), a primitive function that judges whether a memory area
  spans LLD's segment boundary or not.

  It's difficult to convert some IOMMUs to use the IOMMU helper but
  iommu_is_span_boundary is still useful for them. So this patch exports it.

  This is needed for the parisc iommu fixes.

• 0291df8cc   iommu sg: add IOMMU helper functions for the free area management ... Browse Code »

  This adds IOMMU helper functions for the free area management. These
  functions take care of LLD's segment boundary limit for IOMMUs. They would be
  useful for IOMMUs that use bitmap for the free area management.
