From: Jiri Olsa
Date: Sun Feb 14 2016 - 11:04:48 EST


hi,
adding support to store CPU cache details under perf data.

$ perf report --header-only -I
...
# cache info:
# L1 Data 32K [0-1]
# L1 Instruction 32K [0-1]
# L1 Data 32K [2-3]
# L1 Instruction 32K [2-3]
# L2 Unified 256K [0-1]
# L2 Unified 256K [2-3]
# L3 Unified 4096K [0-3]
...

Plus some libapi additions.
