[PATCH] RTC subsystem: sysfs interface This patch adds the sysfs interface to the RTC subsystem. Each RTC client will have his own entry under /sys/classs/rtc/rtcN . Within this entry some attributes are exported by the subsystem, like date and time.

rtc-cmos alarm acts as oneshot Start making the rtc-cmos alarm act more like a oneshot alarm by disabling that alarm after its IRQ fires. (ACPI hooks are also needed.) The Linux RTC framework has previously been a bit vague in this area, but any other behavior is problematic and not very portable. RTCs with full YYYY-MM-DD HH:MM[:SS] alarms won't have a problem here. Only ones with partial match criteria, with the most visible example being the PC RTC, get confused. (Because the criteria will match repeatedly.) Update comments relating to that oneshot behavior and timezone handling. (Timezones are another issue that's mostly visible with rtc-cmos. That's because PCs often dual-boot MS-Windows, which likes its RTC to match local wall-clock time instead of UTC.)

[PATCH] RTC gets sysfs wakealarm attribute This adds a new "wakealarm" sysfs attribute to RTC class devices which support alarm operations and are wakeup-capable: - It reads as either empty, or the scheduled alarm time as seconds since the POSIX epoch. (That time may already have passed, since nothing currently enforces one-shot alarm semantics.) - It can be written with an alarm time in the future, again seconds since the POSIX epoch, which enables the alarm. - It can be written with an alarm time not in the future (such as 0, the start of the POSIX epoch) to disable the alarm. Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN": alarm after 10 minutes: # echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm alarm tuesday evening 10pm: # date -d '10pm tuesday' "+%s" > wakealarm disable alarm: # echo 0 > wakealarm This resembles the /proc/acpi/alarm file in that nothing happens when the alarm triggers ... except possibly waking the system from sleep. It's also like that in a nasty way: not much can be done to prevent one task from clobbering another task's alarm settings. It differs from that file in that there's no in-kernel date parser. Note that a few RTCs ignore rtc_wkalrm.enabled when setting alarms, or aren't set up correctly, so they won't yet behave with this attribute.

[PATCH] RTC gets sysfs wakealarm attribute This adds a new "wakealarm" sysfs attribute to RTC class devices which support alarm operations and are wakeup-capable: - It reads as either empty, or the scheduled alarm time as seconds since the POSIX epoch. (That time may already have passed, since nothing currently enforces one-shot alarm semantics.) - It can be written with an alarm time in the future, again seconds since the POSIX epoch, which enables the alarm. - It can be written with an alarm time not in the future (such as 0, the start of the POSIX epoch) to disable the alarm. Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN": alarm after 10 minutes: # echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm alarm tuesday evening 10pm: # date -d '10pm tuesday' "+%s" > wakealarm disable alarm: # echo 0 > wakealarm This resembles the /proc/acpi/alarm file in that nothing happens when the alarm triggers ... except possibly waking the system from sleep. It's also like that in a nasty way: not much can be done to prevent one task from clobbering another task's alarm settings. It differs from that file in that there's no in-kernel date parser.

rtc: simplified rtc sysfs attribute handling This simplifies the RTC sysfs support by removing the class_interface that hooks it into the rtc core. If it's configured, then sysfs support is now part of the RTC core, and is never a separate module. It's another step towards being able to remove "struct class_device".
