Hi Sebastian,
Hi Carsten,
We could save a short history of RT tasks along with their uninterrupted runtime and, in case of throttling, print the one with the longest uninterrupted runtime.
A sched_switch tracer would do that. It only does not stop and records SCHED_OTHER as well. Maybe the tracing folks have an idea.
