Subject: gpe-handler / acpi on ASUSL2400D
Date: Wed, 26 Mar 2003 14:36:13 +0100	[thread overview]
Message-ID: <200303261436.13123.post@sthias.de> (raw)

Hi,

i'm a newbie on both acpi- and kernel-programming.
I've got an ASUSL2400D-laptop and kenel 2.5.65.

Upon pressing one of my laptops hotkeys, I receive an error message about
a missing gpe-handler.
After fiddling a bit, I wrote a module that installs a gpe-handler for 0x1D 
(the one triggered by my hotkeys). The handler calls "\_GPE._L1D" (using 
acpi_evaluate_object ...). Only then can I receive notify-events for 
"\_SB_.HOTK" and only then buttons like switching LCD-Backlights off or 
changing the brightness work.

My question: Why do I have to install a gpe-handler by myself if there is
a mehod "\_GPE._L1D" in dsdt. Is that the usual way to do such things?

Thanks in advance
     S. Thias
