Greetings, With OpenBSD 5.6 release, I finally have a pretty functional (and usable) hibernation function (not on all my hardware, but at least for a not-so-recent HP laptop it works!).
I was digging into my scripts in order to apply some quirks before hibernating the machine, and noticed that the man page lacks some info. In particular, the code already support a specific file to be executed before entering the S4 state (/etc/apm/hibernate), even if uses the same file (/etc/apm/resume) after resuming from both S3 and S4 (if my understanding is wrong, please correct me). So: 1) a proposed patch for the man page (as per the 5.6 code): --- ./usr.sbin/apmd/apmd.8 Thu Jul 24 03:04:58 2014 +++ ./usr.sbin/apmd/apmd.8.patched Sun Dec 7 17:47:58 2014 @@ -137,14 +137,15 @@ in the requested state after running the configuration script and flushing the buffer cache. .Pp -Actions can be configured for the following five transitions: +Actions can be configured for the following six transitions: suspend, +hibernate, standby, resume, powerup, and powerdown. -The suspend and standby actions are run prior to +The suspend, hibernate and standby actions are run prior to .Nm performing any other actions (such as disk syncs) and entering the new state. @@ -159,6 +160,7 @@ Default device used to control the APM kernel driver. .Pp .It /etc/apm/suspend +.It /etc/apm/hibernate .It /etc/apm/standby .It /etc/apm/resume .It /etc/apm/powerup @@ -169,6 +171,7 @@ by examining the name by which it was called, which is one of suspend, +hibernate, standby, resume, powerup, 2) a question: why two different files for entering suspend/hibernate states, but only one for resuming? At the moment, I do not apply any quirks on resume, but having the possibility to differentiate b/w S3 and S4 wake-up could be useful in some corner cases.
