Reformat the output of the `adjtick` test in tools/testing/selftests/timers/ to display results in a clean tabular format.
Previously, the output was printed in a free-form manner like this:
Each iteration takes about 15 seconds Estimating tick (act: 9000 usec, -100000 ppm): 9000 usec, -100000 ppm [OK]
This format made it hard to visually compare values across iterations or parse results in scripts.
The new output is aligned in a table with clearly labeled columns:
Each iteration takes about 15 seconds
| Requested (usec) | Expected (ppm) | Measured (ppm) | Result | |------------------|----------------|----------------|---------| | 9000 | -100000 | -100001 | [ OK ] | | 9250 | -75000 | -75000 | [ OK ] | ...
This improves readability, consistency, and log usability for automated tooling.
No major objection from me, but also I've not followed too closely if the kselftest output formatting has been formalized further (I know it was moving towards TAP), but it seems this test hasn't been converted yet, so it probably isn't negatively impacting things.
So it might be worth looking into getting the output to be happy with TAP while you're tweaking things here.
