ath9k/PCI 168C:002C

hi,

i'm currently setting up karmic (64bit) an asus eeepc 1005p, and i've
found the following in the debian wiki:
http://wiki.debian.org/DebianEeePC/Model/1005P
i'm giving this laptop to another person on wednesday, but until then, i
might try to compile the ath9k module with the suggested addition of
that PCI id.

unfortunately, i haven't really found anything on how to do this (in a
least-invasive fashion). i've looked
into /usr/src/linux-headers-2.6.31-17/drivers/net/wireless/ath/ath9k,
but there's only a Kconfig and a Makefile, but no sources.

can you people help me modify, compile and test this module?

Seems more like a "how do I recompile my kernel on Ubuntu" question to me...

You can add the ID at the runtime:

echo "168c 002c" > /sys/bus/pci/drivers/ath9k/new_id

You should be able to compile compat-wireless on Ubuntu.  Then you can  
modify ath9k in the compat-wireless sources.  But I'm not optimistic.   
The wiki link suggests that further changes to the driver are needed.

You can also try MadWifi trunk to support the device.  It should  
compile out-of-box.  You can use the same trick to add the ID, just  
replace "ath9k" with "ath_pci".

Re: ath9k/PCI 168C:002C

thanks for your hints! unfortunately, as you expected, simply adding the
PCI id doesn't do the trick. seems like a couple of people tried it
already:
http://forum.ubuntuusers.de/topic/atheros-ar5b95-geht-unter-unr-9-10-nicht/
(in German).

i haven't tried madwifi yet, though.

regards,
bernhard

Please try the patch that was posted at
http://bugzilla.kernel.org/show_bug.cgi?id=15180

You can apply it to compat-wireless.

I was wrong, it won't work as is.  The ID should be added to HAL as
well.  Unfortunately, I don't know which initialization values are
needed for the chip, and I cannot figure it out from the ath9k patch.
