Sorry about the ambiguity. I am using x86-64 architecture in user mode. Basically, I am trying to log all the cache activities when I run a guest program with QEMU. That's why I asked whether QEMU simulated CPU caches. I was assuming if QEMU did not simulate CPU caches then there would be no way to do this (Correct me if I am wrong). Is there a way to do this? Pointer to the 2009 thread: https://lists.nongnu.org/archive/html/qemu-devel/2009-06/msg01353.html
