site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Are there any drivers required for the machine that are not part of the open source Darwin project? Yes. Having looked over the Darwin download page, I'm guessing that the network and hard disk drivers are kernel level modules, and the video driver for Darwin is a user-space component of the X11 distribution, correct? Drivers are not part of the kernel, per se. They, and their supporting libraries ("Families") are handled as loadable modules. = Mike _______________________________________________ Do not post admin requests to the list. They will be ignored.

I assume this includes the Macbook Pro with Intel Core 2 Duo processor, correct? You can generally safely assume that a Darwin source release that post-dates the release date of your hardware will work. Yes. I assume that this is also true for the desktop machines. Correct? IONetworkingFamily, IOStorageFamily and their respective hardware- specific drivers are all built as kernel extensions, yes. I'm not familiar with X11 for Darwin. MacOS X video drivers are supplied in binary-only form and typically comprise several kernel extensions. Our project requires being able to do compiler analysis of the entire kernel source. I see. That may be a problem, but I imagine we can work around it. The Darwin kernel we build from the open source sources should be able to load and use these drivers, correct? Yes, that's correct. You will want to be careful about applying software updates to your system, as interface versions do occasionally get bumped, but for the most part you should not have any problems here.
