freebsd-dev/sys/conf/majors

# $FreeBSD$
#
# This list is semi-obsoleted by DEVFS, but for now it still contains
# the current allocation of device major numbers.
#
# Unless very special circumstants demand otherwise, all device drivers
# are able to use a dynamically allocated major number.  If the d_maj
# element of the cdevsw is uninitialized (preferred) or initialized to
# MAJOR_AUTO, this dynamic allocation will happen.
# 
# 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.
#
# The names marked with a '*' is belived to be allocated for code inside
# the CVS tree.

Note that MAJOR_AUTO is now the default if d_maj is not initialized. This is more robust and prevents the hijacking of /dev/console for the typical mistake. Remove unneeded MAJOR_AUTO uses, it is only needed explicitly now if the driver source has cross-branch compatibility to old releases. 2003-03-09 11:03:45 +00:00			`# are able to use a dynamically allocated major number.

We are developing a device driver of Smart Capture Card. Smart Capture Card is a kind of video capture card, PCMCIA type II, and made by IBM Japan co.. Unfortunately, it is sold in Japan now. The device driver is working on the latest pccard-test package by Tatsumi HOSOKAWA and bsd-nomads. Some applications are also working. For example, xscc is a video moniter client on X-window, vic-2.7b2 is a video conference tool. We have a contract with IBM Japan. From the contract, we cannot release the source code exept the permit of IBM Japan. But I think they will permit us in few weeks.

This file lies by saying 200-255 are reserved for local use, thus implying that they aren't used for the rest of the system. Fix the lies: 253 is used by mfs (bad MFS for not registering it). 254 is a magic cookie inside of the dev code in at least one place. 255 is -1 which is magic in a different way in the dev code. So, that means that 200-252 are reserved for local users. A grep for 252 didn't turn anything up, so I'm assuming it and lower are safe. And I thought I was being smart by allocating our local major numbers from 254 on down. This caused very very odd problems that were hard to track down: close not being called, sync failing at reboot, etc. 2000-06-14 23:34:22 +00:00			`252 ?? entries from 200-252 are reserved for local use`
