Adding hooks at module load time when RTCs are registered could be done, but then you have the issue that userspace might have set the clock via something like ntpdate, so Comment 4 Bug Zapper 2008-04-04 09:44:09 EDT Based on the date this bug was created, it appears to have been reported during the development of Fedora 8. This clock should be battery-backed, so that it reads the correct time when the system boots from a power-off state. And discussing with them just leads to ignored patches/bugfixes.

Perhaps double-check with someone that has a RTC unit if that option does anything? Sep 14, 2003 Posts: 4228 View posts Location: Queanbeyan, Australia #2 Posted by squidgit: Tue.

Again, this doesn't change anything on systems with a "persistent" clock. http://www.serverphorums.com/read.php?12,955967 And in any case, feel free to completely ignore these patches.

There is a "deprecated" warning in the syslog coming from the spi of the board file so perhaps that is the cause. Also, /sys/class/rtc exists but is an empty directory, but I'm not sure waht that means. Chrome Os Download

The mechanism I want to use is the following: The RTC subsystem now maintains the ID of the RTC device which was used for hctosys (in rtc_hctosys_dev_id) and therefor specifies the If the clock you specify here is not battery backed, it may still be useful to reinitialize system time when resuming from system sleep states. Attached is a respun version. Check This Out Yea, this issue was brought up previously, but we never got around to a solution that could be merged.

This may upset some RTC users.

What use does it have to people with RTC hardware? "The driver for this RTC device must be loaded before late_initcall functions run, so it must usually be statically linked." All That a good start to get this working in the kernel. We recommend upgrading to the latest Safari, Google Chrome, or Firefox. But if someone wants these patches based on 3.15, feel free to notice me.

And don't try to tell me I'm uncooperative. I've written that because I will not add a totally unnecessary lock in a code path which does set the system time. And the silence as response to my repost of my already working patches just proved that isn't true. http://netfiscal.com/unable-to/gentoo-drivers-rtc-hctosys-c-unable-to-open-rtc-device.html Comment 1 Chuck Ebbert 2007-09-07 11:03:34 EDT rtc is not used for timekeeping.
