Just a quick update.
The hardware-independent part of VoodooWireless framework is almost completed. What remains is handling of scan results, and handling the various apple80211Request() function calls and mapping relevant ones to hardware-dependent functions.
Out of these the first part is somewhat complicated as a lot of decisions need to be taken on which results to store, for how long, when to renew them, which ones to send to Airport, which ones to choose while associating, and so on. The second part is more mechanical work, as there are something like 25-30 message types to respond to (or map to hardware-dependent function calls).
Once these are done, the hardware-dependent parts of the HAL (for 3945) will be written. I’ve gone through the FreeBSD wpi driver already during my trip last week, and have a somewhat clear idea of how this card works. It is different than 2200BG in many respects, but also similar in many other respects. Some things that the 2200BG firmware handled for us, need to be handled in software for the 3945 (like manually creating probe request frames for scanning). But other things are more streamlined that 2200BG.
All in all, it should be an interesting experience. Let’s see how long it takes to complete.
Total time logged so far is 336 hours, out of which 46 hours have been spent working on the “new” architecture.
