[LTP] poll02 threshold overruns

[Kshitij Malik]

Thank you Cyril for the clarification.

I understand what you mean. I guess I just have to ignore this particular test for our platform. We know polling works as poll01 test passes without any issue and hence it is not an issue with our BSP or kernel.

Thank you for your support.

Hi!
> What kernel configurations are we talking about here?

I'm afraid that there is quite a lot, starting at scheduller choice,
support for hardware hrtimers or CONFIG_HZ, etc. I'm not expert on
kernel timers to make an exhaustive list.

> Is there a formula to calculate threshold based on CPU speed and kernel parameters?

I doubt that there is one. The problem is quite complex and the result
wouldn't be worth of the work.
