"absolute" means it retains original value before and after the filter applied. In patch 5, I made the "absolute" as default since it makes more sense IMHO. $ perf report -s comm # Overhead Command # ........ ............ # 74.19% cc1 7.61% gcc 6.11% as 4.35% sh 4.14% make 1.13% fixdep ... $ perf report -s comm -c cc1,gcc --percentage absolute # Overhead Command # ........ ............ # 74.19% cc1 7.61% gcc $ perf report -s comm -c cc1,gcc --percentage relative # Overhead Command # ........ ............ # 90.69% cc1 9.31% gcc Note that it has zero effect if no filter was applied. I only added the option to perf report for now. If it looks good to you I'll add it to perf top too.
