Take a look at Documentation/IO-mapping.txt in the Linux source tree. ian> Question 2: Which memory type should be use given a continuous ian> range of physical memory? It seems simpler to use the ian> DAT_MEM_TYPE_IA type since no translation is needed. But is not ian> there any limitation to the memory to be registered using the ian> DAT_MEM_TYPE_IA, contrasted with the DAT_MEM_PHYSICAL type? If you have physical memory, use DAT_MEM_TYPE_PHYSICAL. If there is only 1 region, the array should only have 1 element. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
