Level 2 data cache event counters?

Below is a list of all the event counter I have available on my Ivy Bridge CPU. It contains "L1D" cache event counters, but there are no "L2D" counters- only "L2". I was under the impression the L2 cache is split in to data and instruction caches. 

(I have read the descriptions of the below event counters and the "L1D" says "L1 data cache" and the "L2" says "L2 cache", implying it is not specific to the data cache).

What event counters should I use to measure data cache misses for L1/L2/L3, ignoring instruction cache misses?

Have attached the list of hardware event counters in this message.

T C:

please check out this thread: http://software.intel.com/en-us/forums/topic/506796 

yes, L2 cache is "unified" wrt the CPU.  Are you doing any GPU code excution?
