The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=cc7854e10903cd4726a4da6610ebf4dcf69de352 commit cc7854e10903cd4726a4da6610ebf4dcf69de352 Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2024-10-14 21:57:16 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2024-10-14 22:03:58 +0000 uart: export rclk via sysctl To help debugging, export the rclk a uart is using as dev.uart.X.rclk. It can be opaque when it is wrong since any error messages printed to the system console using the wrong rclk aren't informative.
