From: Ingo Molnar Date: Wed, 12 Nov 2008 10:55:41 +0000 (+0100) Subject: tracing: branch tracer, tweak output X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f88c4ae9f8c3939bee4337c75c7a673b5de7a8a7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git tracing: branch tracer, tweak output Impact: modify the tracer output, to make it a bit easier to read Change the output from: > bash-3471 [003] 357.014755: [INCORRECT] sched_info_dequeued:sched_stats.h:177 > bash-3471 [003] 357.014756: [correct] update_curr:sched_fair.c:489 > bash-3471 [003] 357.014758: [correct] calc_delta_fair:sched_fair.c:411 to: > bash-3471 [003] 357.014755: [ MISS ] sched_info_dequeued:sched_stats.h:177 > bash-3471 [003] 357.014756: [ .... ] update_curr:sched_fair.c:489 > bash-3471 [003] 357.014758: [ .... ] calc_delta_fair:sched_fair.c:411 it's good to have fields aligned vertically, and the only important information is a prediction miss, so display only that information.
