Hi folks,
I'm running some perf program on my x86-64 machine with 4.1.12-rt13
kernel, but I found just 8 perf events can be showed up with "perf stat
-e" on -rt kernel, but mainline kernel is fine.
I traced 14 events (tried different number in my test, always > 8), then
I got:
29692 cs
104 page-faults
104 minor-faults
0 major-faults
100122071 iTLB-load-misses
447793 dTLB-load-misses
13655 dTLB-store-misses
201620583 branch-misses
<not counted> cache-misses (0.00%)
<not counted> cycles (0.00%)
<not counted> dtlb_misses_walk_duration (0.00%)
<not counted> dtlb_misses_walk_completed (0.00%)
<not counted> itlb_misses_walk_duration (0.00%)
<not counted> itlb_misses_walk_completed (0.00%)
No matter how many events are traced, just 8 events are showed with
meaningful data, all others are showed up as "not counted".
Any hint is appreciated.
Regards,
Yang
