I use the rtc-debug and amlat to generate histograms of latencies
which is what I was trying to do when I found the rtc problem the
first time. I believe that rtc-debug/amlat is much more accurate for
generating histograms of latencies than realfeel is because the
instrumentation is in the kernel rather than a userspace program.
ah, ok - nice. So rtc-debug+amlat is the only known-reliable way to
produce latency histograms?
Btw., rtc-debug's latency results could now be cross-validated with
-V0.4's wakeup tracer (and vice versa), because the two are totally
independent mechanisms.
