Introduction

This page describes how to test tmlinux using LTP. The Linux™ Test Project (LTP) is a joint project started by SGI™ and maintained by IBM®, that has a goal to deliver test suites to the open source community that validate the reliability, robustness, and stability of Linux. The LTP testsuite contains a collection of tools for testing the Linux kernel and related features. For more information, please goto http://ltp.sourceforge.net

Details

1. checkout LTP

checkout LTP using the following command:

svn checkout http://tmlinux.googlecode.com/svn/trunk/ltp-base

Let's suppose you checkout ltp-base at /home/guohr/workdir/tmlinux/ltp-base

2. Set compiler and PATH environment

Edit Makefile at /home/guohr/workdir/tmlinux/ltp-base/ and set CROSS_COMPILE as the compiler prefix you are using.

For PNX1500 nohost, you should set CROSS_COMPIL as trimedia-gss-linux-tcs-pnx1500el_fp64-uclibc-

And then set PATH environment variable, so that shell can find the compiler you are using. For PNX1500 nohost, you should set PATH using the following command:

export PATH=$PATH:/home/guohr/workdir/tmlinux/sysroots/pnx1500_nohost_uclibc/x86-linux2/

3. Build and Install LTP

Now build and install ltp using the following commands:

cd /home/guohr/workdir/tmlinux/ltp-base
make uclinux
sudo make uclinux_install

4. Install LTP to target root filesystem

let's suppose tmlinux target root filesystem in your machine is /home/guohr/workdir/ tmlinux/export, you should install LTP using the following commands:

cd /home/guohr/workdir/tmlinux/ltp-base/

make ltp directory structures

mkdir -p /home/guohr/workdir/tmlinux/export/opt/ltp-base/testcases/
mkdir -p /home/guohr/workdir/tmlinux/export/opt/ltp-base/runtest
mkdir -p /home/guohr/workdir/tmlinux/export/opt/ltp-base/pan

install testcases of LTP to target root filesystem.

sudo chmod a+x testcases/bin/*
sudo cp testcases/bin/ /home/guohr/workdir/tmlinux/export/opt/ltp-base/testcases/ -rf

copy test cases file of LTP to target root filesystem

cp runtest/syscalls* /home/guohr/workdir/tmlinux/export/opt/ltp-base/runtest/

copy pan to target root filesystem

chmod a+x pan/pan
cp pan/pan /home/guohr/workdir/tmlinux/export/opt/ltp-base/pan/

copy test script to target root filesystem

cp runltpmsh.sh /home/guohr/workdir/tmlinux/export/opt/ltp-base/

5. execute LTP

Now boot up trimedia machine.

Before run LTP testcases, you need to tell runltpmsh.sh which testcase set you want to execute. To do that, you need to set CMDFILE in runltpmsh.sh. For example, you want to run testcases in syscalls01, you should set CMDFILE="syscalls01"

To execute ltp, at your trimedia machine's console

cd /opt/ltp-base/
./runltpmsh.sh

the raw testresult will print on the screen, and test result file will be located at /tmp/ltp-$(pid)/ directory.
