Dear all,
I'm trying to measure the LLC events of a program. I'm running
linux-tools-3.2.0- 34 on a fairly recent 4 core Intel machine. For a
certain program that reads a 64 MB file into memory, I get
Performance counter stats for './algo data/E.dna':
0 LLC-loads
0 LLC-load-misses
26,538,349 cache-misses
4,465,644,541 L1-dcache-misses
35.116615511 seconds time elapsed
I have tried this in another machine, and it does give me some results
for LLC. Also Valgrind gives me results (different from 0, that is)
Any idea what I'm doing wrong? Anyone else experiencing this problem
with perf right now? Please let me know if I need to provide more
information.
Thanks.
