Debug / Driver / Kernel / WiFi

Hi All,

I try to make new driver for AR5424* WiFi Module (ath0) becouse of a lot
of issues on my Fujitsu Esprimo Mobile U9210 Laptop. (Just not working
out of the box)

* https://cvsweb.openbsd.org/src/sys/dev/ic/ar5212.c
* https://cvsweb.openbsd.org/src/sys/dev/ic/ar5xxx.c
...

Could you be so kind to answer:

1. How can I try my new Driver without Build Kernel each time.
2. What kind of tools can I use for Debuging WiFi ... (just examples)
3. Any info about OpenBSD Drivers ? Developers Guides (Just for OpenBSD)
? // not man ath !

Many Thanks
Oleg Pahl
