Well, we probably wouldn't `reserve' major numbers before they are needed. However, with the current approach, this is just a single #define statement in your code anyway, so i don't think you gotta worry much about it yet. Simply use major # 20 (``local use'') by now to develop it. Basically, if you look at the latest copy of the file /sys/i386/conf/majors.i386, you'll see what's the next available number. > I will be contributing this driver, unless rejected, to the > freebsd project. Please adhere to style(9) if you intend to contribute it. If you care for it from the beginning, it's much easier than changing things later. > I also need to know what kind of man page text I need to go along with > this. I have never done any man pages. Basically, pick some comparable device driver man page from section 4 (/usr/src/share/man/man4/). Unless the driver exports some kernel API functions (i.e. non-`static' functions etc. that can be reused in other parts of the kernel), section 9 man pages are not required. I think there are a number of people around in the committers club who are knowledgable about man pages, so if you ask nicely for a review/ style fixup, it's likely that you should find someone. Finding a kernel committer who's knowledgable enough for at least a cursory review of your code *and* who also has the time to do it is probably much harder. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
