If you want the kernel's idea of time to be wrong up to a second or two, then you can rely on the kernel's time setting. Please realise that the kernel has always set the time from the RTC, even on x86 where hwclock has been used. hwclock, however, has some advanced features and advantages that are beneficial if you're after accuracy. 1) hwclock will try to read the RTC as close to a second-change as possible, so that the time read from the RTC is as close to the second. 2) hwclock can measure and correct the RTC time for its own drift if hwclock has been allowed to capture and process the offset. What this means is that hwclock has the capability to precisely set the kernel's time at boot, way more accurately than the kernel does. The kernel's time setting is focused on speed, not accuracy. So, if your userspace application is to monitor something using a precise timestamp, and you are NTP synchronising (or other method) the time on the system, then you need the kernel's idea of time to be set much more precisely to avoid NTP making big corrections over the following three to six hours. This happens because NTP will slew the clock for a few seconds of difference, which makes storing and reloading the PPM value useless, and can also mean that in such a monitoring application, the results are unreliable until NTP has re-stabilised. Here's an example of an application where this may matter: average speed camera system. You have two cameras over a section of road, each with their own processing, which are NTP synchronised. Each reads the numberplate of passing vehicles using ANPR technology, and timestamps the passing of the vehicle using their local clock. The distance is known, so it's an easy calculation to calculate the vehicle speed. If the vehicle speed is over the limit, the driver is fined. Consider what the implications are if one of the systems rebooted and then had incorrect time (up to two seconds wrong) for up to six hours after - a two second error is about a 3% error in recorded speed. Would you want to be sent a speeding fine from such a system? (We have the first non-motorway road in Surrey, UK to have average speed cameras installed down its entire length because of "piston heads" who think the speed limit is 60mph rather than the sign- posted 40mph.) Another, probably more relevant application is a stratum-1 NTP server synchronised via PPS to a GPS. I wonder how many people are aware that if you reboot such a setup relying on the kernel's time setting only, the time sent to clients will be wrong while NTP slews the local clock. I've seen these effects locally, where rebooting exactly such a system results in slaved systems which have no other source of time also making big corrections. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up ^ permalink raw reply [flat|nested] 20+ messages in thread

After a quick look into the reference manuals: Patch 5b72505 ("ARM: dts: imx53: add srtc node") is bad. The i.MX53 provides an RTC more close to the i.MX6 instead (e.g. rtc-snvs.c). But unfortunately it uses a different register layout than the i.MX6 does. So we can't use this driver without i.MX53 specific adaptions. But at least 5b72505 should be reverted. jb -- Pengutronix e.K. | Juergen Borleis | Industrial Linux Solutions | http://www.pengutronix.de/ | ^ permalink raw reply [flat|nested] 20+ messages in thread

Looked in the vendor kernel and this is the rtc driver for mx53: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01 ,which is a different one from the dryice one: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-imxdi.c?h=imx_2.6.35_11.09.01 I will send a revert for 5b72505 ("ARM: dts: imx53: add srtc node").
