Well then probably someone needs to write a device driver for this, just
like for Toshiba's special device.

Actually, it has already been done. Right now, we're working with Julien to 
simplify the code and to add some features. The code is now under heavy 
re-development, and we'll make an appropriate announce once it becomes 
stable enough.

Since we were aiming at merging the driver with the ACPI code (more or less
on the same basis the Toshiba driver is) anyway, we can as well ask right
now, whether this would be possible somewhere in the future?

Of course! This is exactly what I was hoping for.

Well, here is a new version of the driver. It was tested against
2.4.21-rc2 + acpi-20030512-2.4.21-rc2.diff

Any comment welcome

Hi Julien,

Just a few suggestions about your copyright and credits:

You should remove Jonathan Buzzard from the copyright, since he didn't write any 
of the code.

You don't have to keep my copyright since I don't really see much of my code 
left, maybe just give me a credit if you'd like.  (If you keep it, it should be 
on a separate line so people know it is a derived work rather than co-authored.)

Perhaps you should remove the credits I wrote (Jonathan Buzzard, Yasushi 
Nagato), since they have no bearing on your current code.

Regards,
-John

Asus ACPI Hotkeys

[Gertjan]

Hi,

I recently bought an Asus Laptop from the L3 series. It has hotkeys, or
multimedia buttons, for volume up, down, mute, internet, mail etcetera.
Especially the volume up, down and mute are the buttons I would like to
see working.

After some research I found out that these buttons are ACPI buttons. In
Windows Asus has a driver which handles the buttons with a nice OSD
interface. But as I use Linux and not Windows, I can't use these buttons
since they are not currently supported. There are loads of programs to
assign commands to special buttons ('hotkeys', 'lineakd', etcetera), but
the problem is, that my buttons do not generate scancodes, because they
are ACPI buttons.

I really would like to have them working. I'm prepared to write a driver
for them if needed and that's why I'm posting this request. Can somebody
help me, where to start, which steps to take? I'll post my results and I
hope that eventually the buttons will get supported in the ACPI patches.

Regards,

Gertjan

Do they generate an event, when you do
cat /proc/acpi/event
and press a button?

Did you (have to) recompile your DSDT and fixed some errors?

Only sleep and poweroff. But that's only 2 out of 10.

No. I tried if it helped, but it didn't. If I recompile my DSDT I don't
get any warnings.

It just seems that no support for these buttons is in the kernel yet.

I'm a little surprised, can you positively confirm that the buttons generate ACPI interrupts?

try
fgrep acpi /proc/interrupts
and see if the number of interrupts increases whenever you press a button.

Then you're sure that the buttons really run over ACPI. Believe me, not much of what I've seen so far did use ACPI for buttons other than the sleep and power button ...

They do. Asus makes all the extra keys (4 silver on top and others,
controlling brightness, volume, or video output) work through ACPI, though
through a special device.

There is currently a driver, made by Julien Lerouge
(http://julien.lerouge.free.fr) that supports both these buttons, and the 2
status LEDs. I'm currently beginning to work on developing this driver
further on, so if you're willing to contribute, you're welcome.

What exactly is the model (and the BIOS version) of the laptop you have?

Re: Asus ACPI Hotkeys

[Gertjan]

Hi both,

I tested it and the driver works for my Asus L3400D too! I'll put up a
page about Linux on the Asus L3400D within a few days... I use kernel 2.5
in stead of 2.4 for better ACPI and CPU frequency scaling support and I'll
take a look at this driver to port it to 2.5. Will this driver be
supported in the ACPI patch sooner or later? What has to be done to have
it supported in the ACPI patch? Maybe it is a good idea to use
/proc/acpi/event and /proc/acpi/button in stead of /proc/acpi/asus/hotk.
Maybe /proc/acpi/led can be introduced for the status leds... Please let
me know what I can do...

Regards,

Gertjan

Re: Asus ACPI Hotkeys

[Julien Lerouge]

Hi,

Check my page : http://julien.lerouge.free.fr/

This driver supports Asus hotkeys, it adds an entry in /proc/
filesystem. Currently, events are redirected to this entry, but in the
next version, they will go directly in /proc/acpi/event.

What this driver dos is rather simple, it installs a handler for the
HOTK/ATKD device you can find in your DSDT.

Regards,
Julien

Please note that in most cases, the volume buttons have nothing to do with 
ACPI. Run "showkey -s", hit any of these keys and see if they register any 
codes. If they do, then you're good to go. On my notebook (Compaq 1722EA), 
that is the case, and I use xevact under X to use them.
