The branch main has been updated by mav: URL: https://cgit.FreeBSD.org/src/commit/?id=68e457df0268113646264883515412af4c8808cb commit 68e457df0268113646264883515412af4c8808cb Author: Alexander Motin <mav@FreeBSD.org> AuthorDate: 2023-12-24 00:10:49 +0000 Commit: Alexander Motin <mav@FreeBSD.org> CommitDate: 2023-12-24 00:10:49 +0000 iichid(4): Restore/increase sampling rate My previous commit by reducing precision reduced the sampling rate from 60Hz to 40Hz on idle system. Return it back to 60-80Hz range, that should be good for mouse smoothness on 60Hz displays.
