Currently that entry provides no mechanism to specify that ptc.g should not be used at all (the entry provides the count of how many ptc.g can happen in parallel, but the spec says that the value "0" means "1" :-( ) There is an ongoing discussion with DIG64 to use a currently reserved field in the table to specify the value "0". If that change is approved, then we can add code to enable Natalie's code based on the SAL table. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
