Oh sure it's broken, but its brokeness is consistent within the same model at least. How mad/stupid would it be to analyze the flow of GPU instructions to detect differences between a normal non-crashing flow (pre-KMS) and a crashing flow (KMS)? Also it would be nice to be able to "pack" these GPU flows in runnable batchsets so that one can eventually find the glitching sequence.
I have done this kind of sorcerery with JTAG so I thought it might be a "tool" for us too.
