Hey Bobby, Thank you very much for your prompt reply. At least your example below "just worked", wow a very new and different gem5 experience. Really loooking forward to the new infrastructure.
This was what I hoping for, now I have a known working configuration and can start tracking down the differences to our config and hopefully get that to work. I will report back if I do not succeed. :-) Thanks again, Antoine On Thu, Oct 28 15:06, Bobby Bruce wrote: > Hey Antoine, > > First of all, multi-core TimingSimple with classic caches will not work, > you have to use Ruby or run a single-core simulation. > > I think we have something in development which can help you out.
