From bbb2cea7e8dd496b41558df1a0ec9205497b7ebf Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 17 Jul 2014 12:55:00 +0200 Subject: perf tools: Add --debug optionto set debug variable Adding --debug option as a way to setup debug variables. Starting with support for verbose, more will come. It's possible to use it now with report command: $ perf --debug verbose ... $ perf --debug verbose=2 ... I'll need this support to add separated debug variable for ordered events change in order to separate debug output out of standard verbose stream.
