Hi, This patch implements automatic page coalescing when separated io page table is used. It uses ignore bits in iommu pde to cache how many entries lower next page level are suitable for coalescing and then builds a super page entry when all lower entries are contiguous. This patch has been tested OK for weeks mainly with graphic devices and 3D mark vantage.
