Reliability and Stability test for our drivers in LSDK

yutaka_ando — Fri, 20 Dec 2019 02:24:00 GMT

Do you have any test scenario / package to test reliability and/or stability of our own device drivers (e.g. DPAA driver) in LSDK? For Linux kernel, there is a test project called LTP (Linux test project). I am looking for something like this.

Hello Yutaka Ando,

we have LTP test, we also have Ethernet interfaces up and down continuously test to verify the stability.

Thanks,

Yiping

Hello yipingwang‌,

Thank you for the answer.

Could we share the test program or test script that perform ethernet interface up / down with customers or 3rd party? If yes, please let me know whom I should ask for.

Best regards,

Ando

Hello Ando,

The test script is similar as the following.

#!/bin/sh

ifs=$1

for i in `seq 1 100`

echo "=========== start rount $i test ========"

for eth in $ifs

echo "================= link up $eth =========="

ifconfig $eth up

sleep 3

echo "================= link down $eth =========="

ifconfig $eth down

sleep 1

done

sh +x up_down.sh "eth1 eth2"

You could setup netperf environment, then execute the up_down.sh script.

Thanks,

Yiping
