Thomas Moestl e8e2c56650 Revamp the busdma implementation a bit: ... - change the IOMMU support code so that it supports overcommittting the available DVMA memory, while still allocating as lazily as possible. This is achieved by limiting the preallocation, and deferring the allocation to map load time when it fails. In the latter case, the DVMA memory reserved for unloaded maps can be stolen to free up enough memory for loading a map. - allow NULL settings in the method tables, and search the parent tags until an appropriate implementation is found. This allows to remove some kluges in the old implementation.		2002-03-24 02:50:53 +00:00
