How to use DTLB_LOAD_MISSES.WALK_DURATION

How to use DTLB_LOAD_MISSES.WALK_DURATION

Hi expert,

   Recently, I am analyzing a performance issue, in which CU has collected lots of PMC events, and i found something strange.

   In one physical core,

   its DTLB_LOAD_MISSES.WALK_DURATION is 45054431.81;

   its DTLB_STORE_MISSES.WALK_DURATION is 25549.30;

   its CPU_CLK_UNHALTED.THREAD_P is 11567496.63;

   with these 3 numbers, I don't know how to get the ratio of DTLB miss percentage.

   Could you please teach me how to use these numbers?

   Thanks,

 Tao
