Sure, they are: 1. INSTRUCTION_RETIRED 2. CYCLES 3. DTLB_LOAD_MISSES:MISS_CAUSES_A_WALK 4. DTLB_LOAD_MISSES:WALK_DURATION 5. DTLB_LOAD_MISSES:STLB_HIT 6. DTLB_STORE_MISSES:MISS_CAUSES_A_WALK 7. DTLB_STORE_MISSES:WALK_DURATION 8. DTLB_STORE_MISSES:STLB_HIT
Please let me know if you need the hexa values of these events as welll. Thank you, Binh On 12/06/2013 07:40 PM, Stephane Eranian wrote:
Hi, Please provide the full list of events you are using. Thanks.On Dec 3, 2013 1:58 PM, "Binh Q. Pham" <phambinh1...@gmail.com <mailto:phambinh1...@gmail.com>> wrote:I am having a problem while using libpfm-4.4.0, which I think related to this question. What I see is that the number of instructions retired drops significantly if I add a few more events to the list of monitored events in my program. I suspect that the added events conflict with the existing ones, hence brings the actual count down. Do you have the same thoughts? Also, could you point me to where I can find information about these conflicting events in order to configure them correctly? How can I know how many performance counters that my CPU has?
