From e2fd1adaf57800bb2a6e20bd59a02e76eb6d7f89 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Mon, 8 Feb 2016 08:25:53 +0000 Subject: base-files: For sysfixtime use hwclock if RTC available MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On systems that have an RTC prefer it to the file-based time fixup (i.e. use hwclock when there is a permanent clock instead of the faked up time logic that is needed when there is not RTC). We can't rely on hctosys kernel feature either as we're usually using RTC as kernel modules which are usually being loaded after hctosys was run, leading in the following error: hctosys: unable to open rtc device (rtc0) Signed-off-by: Daniel Dickinson Signed-off-by: Petr Štetiar SVN-Revision: 48661 --- package/base-files/files/etc/init.d/sysfixtime | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/package/base-files/files/etc/init.d/sysfixtime b/package/base-files/files/etc/init.d/sysfixtime index 4010e06f93..ab946f6518 100755 --- a/package/base-files/files/etc/init.d/sysfixtime +++ b/package/base-files/files/etc/init.d/sysfixtime @@ -2,10 +2,24 @@ # Copyright (C) 2013-2014 OpenWrt.org START=00 +STOP=90 + +RTC_DEV=/dev/rtc0 +HWCLOCK=/sbin/hwclock boot() { + start && exit 0 + local curtime="$(date +%s)" local maxtime="$(find /etc -type f -exec date -r {} +%s \; | sort -nr | head -n1)" [ $curtime -lt $maxtime ] && date -s @$maxtime } +start() { + [ -e "$RTC_DEV" ] && [ -e "$HWCLOCK" ] && $HWCLOCK -s -f $RTC_DEV +} + +stop() { + [ -e "$RTC_DEV" ] && [ -e "$HWCLOCK" ] && $HWCLOCK -w -f $RTC_DEV && \ + logger -t sysfixtime "saved '$(date)' to $RTC_DEV" +} -- cgit v1.2.3
