#8656 closed enhancement (worksforme)

set CONFIG_NO_HZ=y (tickless kernel)

Description

I noticed that CONFIG_NO_HZ=n - I could find a reason why that is, and there are plenty of reasons why it should be enabled.

The only reference to this kernel configuration option I could find was in [10849] from ~3 years ago.

On routers, CONFIG_NO_HZ doesn't really make much sense (and this ticket doesn't list any good reasons).
On targets where CONFIG_NO_HZ was enabled accidentally, it caused some weird issues which we'd like to avoid. I think for routers, disabling NO_HZ is a much better default.
