kernel default configuration

[ghost]

I would like to enable support for the WNA1000M wifi adapter, way smaller than the WNA1100, which is based on a Realtek chip. The main problem is that the ‘rtl8192cu’ driver handling this chip was not part of the 2.6.33-rc4 kernel.

TI has an released and updated DaVinci SDK (3.22.00.02) that is based on a 3.3.0, that contains it. Can I rely on the ‘da850_omapl138_defconfig’ target to create an initial kernel config file, or is there something special to select for EV3 ? (maybe some patches too…)

According to the release notes for DaVinci SDK 3.22.00.02 it's not for the TI AM1808. You might have better luck using a cleaned up kernel tree and just patching it with whatever driver you need. I have starting working on such a tree based off of Torvalds' tree but I have very limited time to work on it at the moment.
If you want to play around have a look at dholm/linux-ev3 branch:mindstorms-ev3. I have already broken out the patches for wireless so if you want to use something else you can just pull those patches out to have a "clean" tree without modifications to wireless and then add whatever wireless patch you want on top of that.

If anyone can tell me what patch LEGO used to add wireless please let me know. I tried a couple of compat-wireless patchsets but none of them match what LEGO did. I know Atheros used to supply modified compat-wireless patches but since Qualcomm redesigned their website I cannot find them anymore. For the time being I used compat-wireless-2.6.33.6 as a base which results in the EV3 changes appearing larger than they actually are. If I find a better matching patch I will replace it.
