[ANN] Atheros 802.11n USB firmware source code released

[Luis R. Rodriguez]

I'm pleased to announce we have released the source code to our
Atheros 802.11n USB Otus/ar9170 device under the GPL. You can grab the
source, compile and use it with the upstream ar9170 device driver.
Patches are welcomed. The git tree available for this is at:

http://git.sipsolutions.net/ar9170-fw.git

For more information please visit the home page for this project is on
our Linux wireless wiki:

http://wireless.kernel.org/en/users/Drivers/ar9170.fw

The ar9170 device driver home page is at:

http://wireless.kernel.org/en/users/Drivers/ar9170

I'd like to thank Johannes Berg and Christian Lamparter for their
incredible contributions to the project both firmware and ar9170
driver so far without which this would not have been possible.

Great! That's a first for any wireless chip...

BTW can we expect a similar firmware source release for ar2524/zd1211?

Great work, it's nice to see this happening so fast!

I just want to say thanks!

I will buy this device very soon.
Is this source for same firmware that was closed?
Will AP mode work in future?

If you were to release the documentation, then it would be really
possible to fix AP mode for this firmware.

If you could just release ath5k documentation.... I would fix its
numerous problems I have with my aspire one (AR2425)...

Best regards,
Maxim Levitsky

What does this mean:

eeprom : ORIGIN = 0x000000, LENGTH = 1024k

Does the device have whole 1M of eeprom?
What is there?

Also what is this:

sram : ORIGIN = 0x100000, LENGTH = 64k

Description says that pram is 32K, but:

pram : ORIGIN = 0x200000, LENGTH = 16k

Best regards,
Maxim Levitsk

Fine, like I expected, but still, I guess there is some 'loader' in
eeprom?

Great.

Thats fine too.

If there were a documentation too.
Isn't it possible to publish it?

This firmware contains so many 'magic' registers.

Exactly.

If you could make it public.....

I am taking even not especially about this device, but
about ath5k AR2425.

My aspire one has several very nasty bugs, and little hope they will be
fixed, and I blame no one for that, developers are busy, and load is
high.

But on the other hand, chances I fix them are low, I already read whole
ath5k drivers, and without documentation it is hard to see what it going
on.

The only way out I see, it to load windows driver in ndiswrapper, pray
that it will work, and then use mmiotrace to see what is done
differently. I really hate going this way.
