The linux-generic implements timers supposing that timers are based
on CPU cycle counter. It's not always true and timer API can have
nothing common with CPU cycles. Thus timer test shouldn't print
here conversion cycles/ns table for time API.

I'm not sure about moving the table to validation test, but it can
be useful to visually see resolution impact.
This patch should be included in
"odp-lng] [Patch 0/4] preparation series before updating odp time API"
https://lists.linaro.org/pipermail/lng-odp/2015-August/014850.html
But before let's clarify it.

Petri,

Maybe this peace of code should migrate to some other place,
but on my opinion it has more common with time API then cpu API.

The table to check time table mixes time/cycles with timer API example, and it
is confusing a little. Here it doesn't bear any sense except time API has something
common with timer API, but that's not true.

Maybe it can be deleted at all, just want to leave it somewhere.

I agree that the code shouldn't be in the timer example. If anything, we
could print the conversion from ns to timer ticks in the example.

Agree. I'll adopt it for timer.

Yes. I didn't saw example for time, and probably there is no reason for that.
Also it's not place for validation.
So, no validation test changes here.
Thanks.

Ola,

The patch with your corrections is included in the series that I sent recently:
"[lng-odp] [PATCH v2 0/5] preparation series before updating odp time API"
