Note, I'm currently working on adding code to detect NMIs to this as well. And perhaps even tracing SMI counters. Just to show what caused the latency, as latency isn't measured by the counters (that I know of).I like the trace report, but for one small thing; I think it's worth either adding units to the reported latency values (us suffix) or putting in a header line that hwlatdetect values are reported in microseconds.
Yeah, adding "us" to the time stamps would be useful. I'll update. -- Steve
