I must have been unclear. I was not suggesting adding hardware. I was suggesting that we could run Linux under Bochs, which is a software x86 emulator. Being what it is, hooks can be added to track "cpu activity" is it occurs within the emulator. This is all a simulation. The key idea I was suggesting was to log processor activity (of the emulator) and develop a viewer program which would help people visualize the activity.

Doesn't Valgrind already do most of what you want?

Can you valgrind a UML process?

Tim, what will this give you that a stack trace won't?

If your stack gets hosed by a bug, a simulator with a complete history of memory writes will help you discover the problem.

I know nothing about Valgrind.
