Generating trace using Tarmac trace plug-in

Hi,

I have a couple of questions regarding generating traces on using the Tarmac trace plug-in. I'm using the FVP_VE_CortexA9x4 fixed virtual platform running Linaro Android.

1- I want to start trace generation at a specific point in time. When I use the start-instruction-count parameter to set the instruction count, I can only see the trace from CPU0 being generated. I don't see the traces from other CPUs. But if I don't use this parameter, I can (correctly) see the traces from all CPUs. Is this a bug?

2- When connecting the ModelDebugger to the running simulation, I cannot see the controls for the Tarmac trace plug-in in the "Set Parameters" section of the Debug menu for the CPU components. Is this also a bug?

3- Is there any way to selectively turn the tracing on/off in the middle of the simulation? I don't know a priori the instruction count that I need to start the tracing, and this makes the start-instruction-count parameter difficult to use.

  Thanks,
