I have a Intel Core i7.
How can I calculate the misses of cache of level L1 in Intel core i7?

I have looked a guide (Core_i7_VTune_SW_Opt_Guide_1.03.pdf) but only It appears the cache misses for L2 and L3.

Thank you.

No. VTune Analyzer v9.1 Update 2 supports Intel Core i7 processors, including L1$ events. See Vtune_DirHelppmn.chm,
searching "About L1 Data Cache Performance Tuning Events"

L1$isnot described in SW optimizationguideline since L1$misses impact the performance lightly.
