I have been reading any information I can find, which is very little, on writing unix device drivers. Specifically I would like information on FreeBSD;) I really want to start simple by writing a character driver that is not attached to a REAL device but just holds on to some memory and allows me to writing some bytes in (write()) and read them back (read()). I don't think this will be very difficult but I need some detailed information specific to FreeBDS on what header files I need to include and how to build my driver as part of the kernel. What directory should I build my driver in? What entry point will the kernel call when the system boots so I can print a pretty little string from my driver showing a sample initialization. I am kinda in the dark here to specifics of this so ALL help is greatly appreciated.
