Re: [tracecompass-dev] Thread Priority in KernelStateProvider

Hi Matthew,
thanks for the reply. To be honest up until now I have not given the data output much thought, but now that you mention it ... I want a quick overview of the current thread when stepping through a kernel trace. Since the Control Flow View already highlights the current thread, what about a new column "Prio" next to the process name or after the ptid column?
Regards Chris
