From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Murray Subject: [PATCH] Bootgraph.pl bug fix Date: Thu, 9 Jun 2011 22:40:10 +0100 Message-ID: <1307655610-28446-1-git-send-email-amurray@mpcdata.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org List-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: trivial@kernel.org Cc: linux-embedded@vger.kernel.org, linux-kernel@vger.kernel.org, Andrew Murray , Andrew Murray This patch removes the assumption of the bootgraph.pl script that the timing information reported by PRINTK_TIME will contain at least one entry with a time of less than 100 seconds. Not all boards correctly reset the system timer and in many cases the inital times reported by PRINTK_TIME is high. When this occurs the bootchart.pl script fails to give any useful output. This patch sets the $firsttime variable to the largest value expected by PRINTK_TIME Signed-off-by: Andrew Murray --- scripts/bootgraph.pl | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/scripts/bootgraph.pl b/scripts/bootgraph.pl index 12caa82..b78fca9 100644 --- a/scripts/bootgraph.pl +++ b/scripts/bootgraph.pl @@ -44,7 +44,7 @@ my %end; my %type; my $done = 0; my $maxtime = 0; -my $firsttime = 100; +my $firsttime = 99999; my $count = 0; my %pids; my %pidctr; -- 1.7.4.1
