This list is the Linux Device List, the official registry of allocated
device numbers and /dev directory nodes for the Linux operating
the Atari platform only.
The symbol {2.6} means the allocation is obsolete and scheduled for
-removal once kernel version 2.6 (or equivalent) is released.
+removal once kernel version 2.6 (or equivalent) is released. Some of these
+allocations have already been removed.
This document is in the public domain. The author requests, however,
that semantically altered versions are not distributed without
**** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
-THE DEVICE REGISTRY IS OFFICIALLY FROZEN FOR LINUS TORVALDS' KERNEL
-TREE. At Linus' request, no more allocations will be made official
-for Linus' kernel tree; the 3 June 2001 version of this list is the
-official final version of this registry. At Alan Cox' request,
-however, the registry will continue to be maintained for the -ac
-series of kernels, and registrations will be accepted.

To have a major number allocated, or a minor number in situations
where that applies (e.g. busmice), please contact me with the
appropriate device information. Also, if you have additional
in "batch mode", so there is likely additional registrations that
haven't been listed yet.
+Fourth, remember that Linux now has extensive support for dynamic allocation
+of device numbering and can use sysfs and udev to handle the naming needs.
+There are still some exceptions in the serial and boot device area. Before
+asking for a device number make sure you actually need one.
+
Finally, sometimes I have to play "namespace police." Please don't be
offended. I often get submissions for /dev names that would be bound
to cause conflicts down the road. I am trying to avoid getting in a
