Package: src:linux Version: 4.0.2-1 Severity: normal Tags: upstream
My cubox-i4pro armhf device has two real-time-clocks. One, snvs, is not battery backed, hence is not useful for setting the system clock on boot after a power failure. The other, pcf8523, does have battery backup. Unfortunately, the snvs is recognzed first, so it become /dev/rtc0 (the pcf8523 becomes /dev/rtc1) and the kernel at boot time uses /dev/rtc0 by default to set the system time from. There does not seem to be any way to over-ride this. There's code in /etc/default/hwclock that would do part of the work in a sysvinit setup, but it seems to be ignored under systemd. In googling about, I stumbled across a proposed patch that would add a kernel command line parameter, "hctosys=rtc<#>' that would over-ride the default, but it seems not to have ever been implemented ( http://lkml.iu.edu/hypermail/linux/kernel/1407.0/03989.html ) Presumably, there is systemd magic that could do the same thing as was available under sysvinit. Is there anybody out there with enough systemd foo to tell me how to do that? Other ways to attack this problem may involve something with udev rules, but I'm not savvy enough to figure that out for myself, either. Personally, I kind of like the kernel command line parameter, but others may have other ideas. Thanks for your consideration!
