10 "cpufreq" test cases failed on "linux-linaro-lsk-highbank".

[Botao]

For pm-qa test suite on "linux-linaro-lsk-highbank", there are 10 failed test cases show up:

cpufreq_01.0/cpu0
cpufreq_01.0/cpu1
cpufreq_01.0/cpu2
cpufreq_01.0/cpu3
cpufreq_02.0/cpu0
cpufreq_02.0/cpu1
cpufreq_02.0/cpu2
cpufreq_02.0/cpu3
cpufreq_05.3
cpufreq_05.4

By comparison, on "linux-linaro-highbank", with the latest available pm-qa test result, happened on 6 February 2014, above test cases also failed there:

https://validation.linaro.org/dashboard/streams/private/team/linaro/pre-built-highbank/bundles/4f414790a5d846e0ffda8a7c438344664c9071ac/fbbd8c3d-a634-41bd-86ba-990bf6b0cf90/

I'm not quite sure above test cases are supported on Highbank, I assume they should work, correct me if I'm wrong.

Since this happens on 2 different projects, I will report a separated bug on "linux-linaro-highbank" later.

Hi Botao,

By default, any platform-specific bug should be assigned to the member
landing team, not to linaro-power-qa. Most of these bugs are incomplete or
buggy drivers. Only if it is proven that the tests are buggy should it be
assigned to linaro-power-qa

In this case, could you please assign this to some developer working on
Highbank? Many times we don't even have access to these platforms such as
in this case.

Regards,
Amit

Looking at the kernel config the cpufreq driver for highbank is being built. I can't see any error output so presumably the issue here is that userspace is failing to load the module somehow (potentially it's not even trying). The module isn't automatically enumerated so this is something that either the testsuite or the hwpack ought to be doing.

Botao, to follow up on what Amit is saying please try to be aware of common issues like this (no cpufreq driver present).

[Lisa Nguyen (lisatn)]

I ran two LAVA jobs (#129522 and #129514) to reproduce the bug, and it doesn't appear to me that cpufreq is supported on highbank. Therefore, the cpufreq test cases do not get executed.
