From ff6a2d00f900005a50b88d15a7beeea0a27a1d37 Mon Sep 17 00:00:00 2001 From: Marcel Moolenaar Date: Thu, 4 May 2006 03:48:06 +0000 Subject: [PATCH] Belatedly add 2 entries relating to the introduction of scc(4) and the overhaul of puc(4). On sparc64 people may end up without serial console if they upgrade without adding scc(4) to their kernel configuration file. --- UPDATING | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/UPDATING b/UPDATING index 75f8a5dbc2eb..113aebce7b1d 100644 --- a/UPDATING +++ b/UPDATING @@ -21,6 +21,21 @@ NOTE TO PEOPLE WHO THINK THAT FreeBSD 7.x IS SLOW: developers choose to disable these features on build machines to maximize performance. +20060428: + The puc(4) driver has been overhauled.
