I just noticed the following: Macintyre:/tmp/oprofile/doc:[0]$ oprofpp --counter=1 -g -i /lib/libc.so.6 Cpu type: Athlon Cpu speed was (MHz estimation) : 1194.693000 Counter 1 counted DATA_CACHE_REFILLS_FROM_L2 events (Data cache refills from L2) with a unit mask of 0x1f (all MOESI cache state) count 600000 Macintyre:/tmp/oprofile/doc:[0]$ oprofpp -g --counter=1 -i /lib/libc.so.6 Cpu type: Athlon Cpu speed was (MHz estimation) : 1194.693000 Counter 0 counted DATA_CACHE_MISSES events (Data cache misses) with a unit mask of 0x00 (Not set) count 600000 First it displays counter 1 (correctly) but the second invocation shows counter 0 which is wrong.
