From 07c039ee370f49a0c5fc690ba473d42d27ccb022 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven <arjan@linux.intel.com> Date: Wed, 7 Oct 2009 12:27:07 -0700 Subject: [PATCH] perf timechart: Work around commit 42e59d7d19dc4b4
Commit 42e59d7d19dc4b4 introduced a sample frequency framework.. .. however it unfortunately changed how perf events get recorded, and caused timechart to miss events to the point that timechart became useless.
This patch causes the timechart code to use -F 0 to not use the new framework when recording timechart data.
