Incredibally useful for debugging kernels using vmware. Vmware com1 is diverted to one side, and gdb listens to the other side. viola.. instant debugging sandbox on one system.

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.
