DTLB-Miss address

Postby arkaprava » Fri Mar 02, 2012 2:53 pm

Hello,

I am new to using PAPI so please pardon me for possibly stupid question.

I was trying to figure out whether I can use PAPI to get linear address of an memory access that has caused a DTLB-miss (possibly through Intel's Precise Event Based Sampling). I am planning to use the linear/virtual address of the DTLB miss causing memory access to classify the DTLB-miss as due to access to stack region or non-stack (e.g., heap, global) memory region. Can somebody put some light on whether this actually could be possible or not ?


Thanks
Arka

PS: I am using Intel Sandybridge machine.

Hi Arka,

Did you manage to get the virtual addresses through PAPI or some other tool? I am looking for to get similar data as well.

Thanks.
