This version unlike previous versions doesn't change the way the rtc driver works. The output of /dev/rtc is preserved also so it doesn't break the existing functionality of rtc. By the same token it won't produce output usable by amlat, but it works for measuring the latency from interrupt to read. It doesn't measure when a poll is satisfied yet because I didn't need that yet. It doesn't trigger the end until the read. kr
