| |
Hi!
( kernel 2.2.14 )
I noticed that user-space APM clients ( receivers of APM events ), usually apmd, can not cancel a pending standby or suspend request. This would be usefull in some cases and the in-kernel clients ( apm.c/send_event() ) can do it.
What I want to do is to start a script ( by apmd ) when the power button is pressed ( it sends a an APM_USER_SUSPEND event to the OS and when the OS acknowledges it , the system goes into suspend ), which then executes "shutdown -r|-h now" and signals apmd to reject the suspend mode ( maybe like "exit 1" -> cancel the event ; "exit 0" -> execute event ).
This way I can do a clean shutdown when the console locks next time :-)
BTW, some weird things I noticed on my Abit BH6 board : When the power-button is pressed , an APM_USER_SUSPEND event is sent to the OS. When the OS replys with apm_set_power_state(APM_STATE_SUSPEND); , the machine is powered off !
If I change the BIOS option "power button override" from Disabled to Enabled , then it works as expected; it only goes to suspend, to turn it off the button has to held for a few seconds.
The big problem is that even if no APM software is running ( like in DOS ), the button has to by depressed for a longer period ( ~5 secs ) to turn the machine off, so I wonder if this option can be switched by the APM driver in the OS ? So it would be "instant off" unless changed by the OS to "only suspend".
