Hi, Thanks so much... it's done now. Yes the patch was not applied correctly. I forgot to add the object file for the patch.

To get the vales you mentioned the simulator needs to know where to look for them, so you need to add some symbols to a newly compiled version of the kernel.

You can have gem5 create an ever on linux's __switch_to function and see what thread is running on which core by inspecting some kernel data structures. This is done for Alpha and for ARM.
