[ath9k-devel] Time-of-flight positioning - Atheros

[Graf Monika]

Hello Everyone

I am currently at a project where I am using Atheros Chipsets AR9590 with the ath9k driver on Debian.
I am wondering how the time-of-flight information can be retrieved per packet in most recent Atheros chipsets.
Could you tell me how that I get that out of the driver? Or which register do I have to access in order to get the hardware timestamp (in nanosec)?

Thank you for your help!

You need an NDA with Atheros and recent proprietary driver for AR9590. 
AFAIK this feature is not documented in datasheets so you need
to dig through the code. At least the low level stuff doesn't look that 
terrible to backport.
I wanted to look at it myself but haven't got time yet.

Would be nice to get it upstream but I don't know how it works with 
licenses and NDA.

Br,
Wojtek

Hey Wojtek

Thank you for your help!
Do you (or anyone else) know if I can get an NDA with Atheros?
It is for my Master Thesis project at the ETH Zurich which I am doing in collaboration with a company,
so I could request it through either of the two organizations. 

Thanks for your help!

Monika
