From: Namhyung Kim Date: Tue, 4 Mar 2014 02:01:41 +0000 (+0900) Subject: perf top: Add --fields option to specify output fields X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6fe8c26d7ab9fbd6748fc40ca5fea1e3131e7236;p=openwrt%2Fstaging%2Fblogic.git perf top: Add --fields option to specify output fields The --fields option is to allow user setup output field in any order. It can receive any sort keys and following (hpp) fields: overhead, overhead_sys, overhead_us, sample and period If guest profiling is enabled, overhead_guest_{sys,us} will be available too.
