Good work Jon. I think something like this will be helpful. Any reason why you could not do SMI detection in user level code running at the highest RT priority? If something is running at the highest RT priority, it should not be preempted by anything. Right? In the past, we discoved discovered periodic SMIs on some hardware platforms by running a user level process in an infinite loop sampling the clock and reporting unexpected delays. Of course, this does hog an entire CPU. -- Mike -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
