Hey š
About 8 months ago on my previous PC Iād came across this document by the creators of a certain testmem5 config 1usmus V3
It explains what each individual error means and possible way to fix, plus the website tells you the amount of time or cycles to run each config.
At the bottom it also gives detailed explanations on certain error codes for different configs and what it could mean
Anyway, I hope this document is helpful to some people, just as much as it helped me
