There's already a cross-platform interface to RTC wakeup alarms; no
new interface is needed (or desirable), much less one that requires
any new or modified /sys/power/... files.
- Enable the wakeup event in /sys/devices/.../power/wakeup
(alternate names include /sys/class/rtc/.../device/power/wakeup)
- Userspace can set the alarm using
* /dev/rtcX and one ioctl: RTC_WKALM_SET
* /dev/rtcX and two ioctls: RTC_ALM_SET, then RTC_AIE_ON
* /sys/class/rtc/.../wakealarm
That works on multiple systems already. I've just posted updates
to make it work for "rtc-cmos" on the RTC list.
