Thomas Moestl f42d907165 When multiple IOMMUs are present in a system, use a single TSB for all ... of them, and couple them by always performing all operations on all present IOMMUs. This is required because with the current API there is no way to determine on which bus a busdma operation is performed. While being there, clean up the iommu code a bit. This should be a step in the direction of allow some of larger machines to work; tests have shown that there still seem to be problems left.		2002-07-16 18:17:03 +00:00
