ath10k: mac80211 driver for QCA9880

ath10k: mac80211 driver for QCA9880

[Kalle Valo]

Hi,

I just pushed initial version of ath10k, our new driver for QCA9880 &
co, to github.com:

https://github.com/kvalo/ath10k

The driver is pretty small, roughly 14 kLOC. Even if the name implies
that this is an evolution from ath9k, the drivers are actually very
different. The biggest difference is that there's now firmware running
on the chip.

Once ath10k is ready I will send it for proper review. But we are not
quite there yet.

Will the firmware be released as free software at some point?

There's currently no plans to open source the firmware for ath10k chips.

So it's best to assume the answer is "no".

We'll be sure to tell people if this ever changes.

Does it matter? The firmware is just a binary logic black box. It's not
likely to even see more than a handful of revisions after the actual
products hit the market.

As long as the driver remains open I don't see any problems with the
open-driver-closed-firmware combination. Intel and Ralink has adopted this
practice to great success, and I don't see any reason why Atheros can't do
the same.

I believe the question was asked as Atheros / Qualcomm has a history
of releasing firmware for their devices, i.e. the ar9170 and ar7010 /
ar9271 chips, I believe Denis was wondering if this practise would
continue.

I don't believe anyone has problems with things being done this way,
we'd just like to know if there's a release scheduled.

.. as I said, there's no schedule for releasing firmware source for
the QCA988x 11ac NICs.

For now, please proceed as if there will never be a firmware source release.

If this ever changes, us in the QCA team will let everyone know. (Most
likely by saying "hey, go here! there's source! yay!.")

Is there any info on it's expected support for virtual stations, APs, etc?

Hardware is still hard to come by it seems..hope that changes soon!

Thanks,
Ben

There are limitations on the maximum number of virtual interfaces and stations
right now. But, the FW is being fixed to support more nodes/interfaces.
Nevertheless, it can't be compared with ath9k. :)

Nice, any idea when these devices will be available to the public?

Luckily I'm in a position where I don't need to speak with marketing and
sales so I have no idea :)

I pushed the firmware temporarily here:

https://github.com/kvalo/ath10k-firmware

I also created a small page to the wiki:

http://wireless.kernel.org/en/users/Drivers/ath10k

But now anyone with QCA9880 or QCA9888 should be able to run ath10k now.
If someone does that we would be very interested about feedback.
