There's a bunch of documentation about this on the Apple developer web site. <http://developer.apple.com/documentation/Darwin/Kernel-date.html#//apple_ref/doc/uid/TP30000422-TP30000532> Also can i configure the darwin kernel and then build the same? If i can configure the kernel how do i do it? I don't really understand your question. You can build the Darwin kernel from source if you like, but you don't need to do this in order to build and load a kernel extension. Similarly, you don't need to specifically configure the kernel in order to load a KEXT. Some classes of KEXTs are loaded on demand when the appropriate hardware is found (I/O Kit) and others can be loaded programmatically at any time. If you're looking for more pointers about implementing a kernel extension, you'll have to provide us more information about what you're trying to do. There are three basic classes of KEXTs on Mac OS X, I/O Kit drivers, VFS plug-ins, and Network Kernel Extensions (NKEs). Your first step is to decide what class of KEXT you want to be.
