Now this test has been fully automated in LAVA, which the dashboard can be found here:

http://validation.linaro.org/lava-server/dashboard/image-reports/linux-linaro-tracking-panda-es

According to the latest test result:

http://validation.linaro.org/lava-server/dashboard/streams/private/team/linaro/pre-built-leb-panda-es/bundles/e2c3839b437ca91c8ef3d13758f498a3bcc6fc07/be357cad-52fd-4a2b-8023-8d223a605061/

This issue still exists.

Failure list:

cpufreq_01.0/cpu0
cpufreq_01.0/cpu1
cpufreq_02.0/cpu0
cpufreq_02.0/cpu1
cpufreq_05.3
cpufreq_05.4
cpuhotplug_07.0/cpu1

Sanjay, have a quick look to see if some config options are missing in the kernel. If buggy code, TI LT should fix.

[Milosz Wasilewski (mwasilew)]

Sanjay,
Any progress here?

[Milosz Wasilewski (mwasilew)]

cpuhotplug_07 also fails on highbank (https://bugs.launchpad.net/linaro-power-qa/+bug/1230403) so this issue might be similar.

[Milosz Wasilewski (mwasilew)]

After a short chat with Sanjay it appears that cpufreq driver might be disabled in the kernel config.

Based on the Kernel configuration file of Linux Linaro ubuntu build 511 (refer to attachment):

Directives are fine the issues is with the TI driver, failing to get the resource.

[Botao (botao-sun)]

@sanjay, if this issue is blocked by lack of source code in TI driver, would you please just remove those failed test cases for TI Panda board?

[Botao (botao-sun)]

Based on the daily test dashboard for TI Panda Linux Linaro ubuntu build 611, all 155 power management test cases passed. But let's wait & see for a longer time since there is still no new build available so far.
