DpcIsr ETW Tracing Broken in RS2?

Hi,

I often use the following commands to generate a DPC/ISR Latency & CPU?Report:

tracelog ?start ?f dpcisr.etl ?dpcisr ?UsePerfCounter ?b 128
<…>
tracelog ?stop

tracerpt dpcisr.etl -report dpcisr.xml

In all versions of Windows, I get a nice XML/HTML report with latencies, CPU duration, etc…

In RS2, at least in build 14986 and later, I get no DPC/ISR?data at all. Has this been broken or changed in some way? Of note, I am using the RS1 Tracelog tool – is a new copy of the RS2 WDK required? Can anyone repro or someone from MS chime in?


Best regards,
