Even though you are the only user ... it would seem prudent to define some generic interface. Right now you just assume (correctly) that all the uncacheable memory has been ignored by Linux. There are two problems with this: 1) Someday that might change. E.g. Linux might need to alloc uncacheable memory for min_state areas for more complex MCA recovery 2) There is no way for another non-kernel user of uncacheable memory to share the resource with you. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Tue Jul 29 14:45:56 2003
