[PATCH 18/52] perf c2c report: Add loads related dimension keys

Arnaldo Carvalho de Melo
2016-10-20T15:05:02Z

Add 3 loads related dimension key wrappers.

They are to be displayed in the main cachelines overall output:

ld_fbhit, ld_l1hit, ld_l2hit

They all display bare numbers of loads for
FB (Fill Buffer), L1 and L2 cache.
