https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259036 --- Comment #7 from Ian Lepore <ian@FreeBSD.org> --- I don't know of any downside to having OPTION PPS in the kernel and not using the feature other than a bit of wasted code space (which probably doesn't add up to more than 1-2kbytes). I don't understand the comment about PPS not being useful on ppc or riscv. You can feed a PPS pulse to a system on any gpio pin or serial port, including usb-serial adapters. If you use ftdi adapters you can get accuracies in the +- 50us range, cheaper brands still get you millisecond accuracy which is as good as a network connection). -- You are receiving this mail because: You are the assignee for the bug.help
