hi,
the c2c output readability heavily depends on headers
being displayed on multiple lines and allowing span
of some headers over multiple columns, like:
# Total %All Total ----- Core
Load Hit ----- -- LLC Load Hit -- ----- LLC Load Hitm -----
# Index Cacheline records Ld Miss %hitm Loads FB
L1 L2 Llc Rmt Total Lcl Rmt
# ..... .................... ....... ....... ....... ....... .......
....... ....... ........ ........ ....... ....... .......
#
0 0x7fbe65acee00 203 2.37% 3.34% 162 26
72 0 20 2 39 11 28
I haven't found use for this under current perf code,
so there's no actual current user in perf code of
those features.
Also available in:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/fixes
thanks,
jirka
