ndation.org> 2007-10-22Intel IOMMU: IOVA allocation and management routinesKeshavamurthy, Anil S This code implements a generic IOVA allocation and management. As per Dave's suggestion we are now allocating IO virtual address from Higher DMA limit address rather than lower end address and this eliminated the need to preserve the IO virtual address for multiple devices sharing the same domain virtual address. Also this code uses red black trees to store the allocated and reserved iova nodes. This showed a good performance improvements over previous linear linked list.
