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.
|
|
(see http://www.freebsd.org/ or from ftp://ftp.freesoftware.com/pub/FreeBSD/)
|
|
|
|
NOTICE: FreeBSD does not use block major numbers anymore, you neither
|
|
need to assign nor use a block major number for any device driver any
|
|
more.
