I know you are going to tell me to rtfm, it's bound to be in there but I can't find anything relevant here so assume I'm stupid and please point me at something obvious :P
I have just become acquainted with the differences between FreeBSD and OpenBSD by porting over the ubtbcmfw driver which seems to build into my Kernel quite happily and I can plug in the Blutonium based USB dongle and my driver recognises it. great!.. However, programming device drivers on OpenBSD isn't quite like I was expecting.. I have modified a few up to now but not brought a new one into the tree before. FreeBSD has a make_dev call to actually make the device nodes for the driver. OpenBSD has makedev which I think does something similar, however, the majority of the drivers that I have examined don't use it. They don't actually seem to have anything within the driver itself that identifies with me as a registration of major and minor device numbers that I can correlate with a simple mknod command so I'm assuming that there is an element of automatic assignment on the part of the device numbers (or maybe I missed some macro that does something for you.. I don't know). Looking at the counterpart driver for this device (ubt) I can't see any reference to major, minor device numbers so I picked something more obvious. the wd driver and I can't figure out how this maps to major number 16 at all. (it's been a long day working from home and the smallest baby has been screaming all day too :(). Can someone give me a hint or point me at a relevant man page about how device numbers are managed in the Kernel source tree this would save me a lot of head scratching... even at the risk of having to slap myself on the forehead and shout "DOH!". -Andy
