acpi-event for online/offline of ac-adapter

acpi-event for online/offline of ac-adapter

[Karl Weigel]

Hello list,

do you think it would make sense to generate an /proc/acpi/event, whenever the 
power-supply gets connected or disconnected?

Bye
Karl

Yes, this already happens.

Hi,

I personally and strongly want the platform hardware to raise SCI upon
AC/DC toggling.

Thanks,

There is one. Well, two actually. One for connecting and one for
disconnecting. ;-)

Sorry to have bothered you with my less-than-new ideas ;-)

Of course I tried to disconnect and reconnect the power supply, and I saw the 
state was getting set to online and offline, but doing the same with a cat 
listening on /proc/acpi/events did not see any events from un-/re-plugging. I 
am rebooting my laptop to verify this behaviour. And yes: In 
/proc/acpi/ac_adapter/AC/state I can see the state switching between on-line 
and off-line, while cat /proc/acpi/event does not see a power-related event. 
(After using modprobe button I can see, whether the power-button has been 
pressed)

I am using version 20030122

(And while I was looking for the place, where the on-line/off-line events 
should be generated I found, that my laptop does not react to echo 2 
>/proc/acpi/processor/CPU0/throttling. Doing the same on my tower does 
produce the expected result. But I wont try to disconnect the powersupply on 
that machine for obvious reasons)

To make the long story even longer: I have seen in the source, that it should 
work, and I have seen with cat /proc/acpi/event, that it does not.



Kind regards

Karl


P.S. Sorry for not staying in the thread, but GMX thougt it a good idea to 
mark your E-Mail as infected and did strange things to it because of that. I 
switched that feature off again.
