Subject: [PACH] cyclictest: Fixed incorrect wakeup reset interface
Date: Fri, 18 Feb 2011 15:15:13 +0900 [thread overview]
Message-ID: <1298009713.10998.11.camel@centos55> (raw)
Dear Clark Williams,
When we try to run ftrace with cyclictest command of rt-test testsuite,
We view the error according to base kernel version.
We need to modify this hard coded interface.
* Test environment:
. -rt patch version : 2.6.33.7.2-rt30
. rt-tests repository version : 0.72
http://git.kernel.org/?p=linux/kernel/git/clrkwllms/rt-tests.git
