Dear Jason, Thank you so much for your reply. Could you please elaborate more on how to "implement a function in Caches.py to dump the data"? As far as I can see, there are only some cache parameters defined in this scripts.. I really have no idea how should I bridge the code there with the runtime cache state (my focus is the L1 D Cache)...
I am not a system person and I am sincerely sorry if it is actually quite obvious... Thank you so much in advance!
