From: Namhyung Kim Date: Mon, 3 Sep 2012 02:53:09 +0000 (+0900) Subject: perf hists browser: Use perf_hpp__format functions X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f5951d56a2ab4181b96806a4746895aaa5a3d72e;p=openwrt%2Fstaging%2Fblogic.git perf hists browser: Use perf_hpp__format functions Override hpp->color functions for TUI. Because line coloring is done outside of the function, it just sets the percent value and pass it.
