I notice that the wistron_btns driver has support for some other Amilo
laptops.  The source says:

 /*
  * If your machine is not here (which is currently rather likely), please send
  * a list of buttons and their key codes (reported when loading this module
  * with force=1) and the output of dmidecode to $MODULE_AUTHOR.
  */

Tino (or anyone with this hardware), could you send dmesg output from

	modprobe wistron_btns force=1

and dmidecode (or "grep . /sys/class/dmi/id/*_{vendor,name,version}"
as Ben suggested)?

Thanks,

 Hello,

 I never tried integrating the code into any "standard way". I just 
 needed a quick fix and I do not have much experience with Kernel 
 programming.

 I agree that running the code without checking the presence of this HW 
 can have bad side effects (however, I did not experienced any on several 
 different laptops).

 I do not have the hardware easily accessible now to provide requested 
 information. I would really appreciate if anybody could take the code 
 and put it into some standard Kernel module.

 Please note, that it is not possible to switch the wifi on by emulating 
 some software keys. It really needs to write to some HW ports. I 
 obtained these numbers by reverse engineering the original 
 Fujitsu-Siemens Windows driver.

 Cheers,
 Martin

Hi,
I'm sorry for the long delay but I can use the laptop only on weekend. 
Here is the output:

It looks like this model is rather different, maybe not a Wistron design
at all.

I would prefer you to test against Linux 3.0, but it appears that the
model detection has not changed since 2.6.26.

Please build and test the attached driver (make && insmod
amilo-rfkill.ko).  It provides a standard rfkill device which you can
control with e.g. the 'rfkill' command, and will only bind to specific
models.

If this works, I'll submit the code upstream.

Ben.

Hi Ben,
Thank you for your code!

Before I built the module (Kernel 2.6.32) I had to insert the include 
line #include <asm/io.h> ( -> inb()-function ?)
With Kernel 2.6.26 I couldn't even built the module.

But loading of the module failed:
# insmod amilo-rfkill.ko
insmod: error inserting 'amilo-rfkill.ko': -1 No such device

In kernel 2.6.32 exists /dev/rfkill but

# rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

# rfkill unblock all

# rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

doesn't work here. Nothing changed.

Thanks,
Tino

That should be <linux/io.h>, actually.

Sorry, I made the driver look for product name "AMILO A1655" but that is
actually the board name.  Could you try changing DMI_PRODUCT_NAME to
DMI_BOARD_NAME?

This is the rfkill device exposed by the regular wireless driver.  Since
it doesn't know anything about the model-specific blocking behaviour, it
appears to treat it as hard-blocking.  But that shouldn't matter if we
can get this new driver working.

Ben.

Yep, that's it. Runs fine!
