[Gems-users] opal trace collection -- exception

[Miray Kas <miraykas@xxxxxxxxx>]

Hi all,

 

I am trying to collect traces from opal but I got stuck with an exception. It should be something minor but I dont know how to fix this.

 

The exception is this:

 

opening file ./mem-opal_trace-001
installing memory hierarchy
Exception error message: attribute timing_model in object cpu0_mem: Value does not match type definition: o|n
system: installMemoryHierarchy: phys_mem0: caught exception (#13).

 

When I look at the timing model, I get 0(null) value:

 

simics> phys_mem0->timing_model
0

I know that this checkpoint works with opal, ruby, opal+ruby but it gets stuck when I want to collect traces.

 

What should I change in my commands or checkpoints to be able to get traces?

 

Thanks,

Miray
