Hopefully, this list will one day be obsoleted by DEVFS, but for now
|
|
|
|
|
this is the current allocation of device major numbers.
|
|
|
|
|
|
|
|
|
|
For local use, you are encouraged to use the reserved numbers.
|
|
|
|
|
|
|
|
|
|
If you intend the driver to be available, send email to the
|
|
|
|
|
hackers@freebsd.org mailing list to see about having a number
|
|
|
|
|
reserved for you.
|
|
|
|
|
|
|
|
|
|
The most "complete" version of this will be the one in FreeBSD-current.
