We've run into problems with running out of dynamicly assign char device majors particullarly on automated test systems with all-yes-configs. Roughly 40 dynamic assignments can be made with such kernels at this time while space is reserved for only 20. Currently, the kernel only prints a warning when dynamic allocation overflows the reserved region. And when this happens drivers that have fixed assignments can randomly fail depending on the order of initialization of other drivers. Thus, adding a new char device can cause unexpected failures in completely unrelated parts of the kernel. This patch solves the problem by extending dynamic major number allocations down from 511 once the 234-254 region fills up. Fixed majors already exist above 255 so the infrastructure to support high number majors is already in place. The patch reserves an additional 128 major numbers which should hopefully last us a while. Kernels that don't require more than 20 dynamic majors assigned (which is pretty typical) should not be affected by this change.

Older kernels had /dev/ramdisk (1, 1) here.

/dev/initrd refers to a RAM disk which was preloaded

by the boot loader; newer kernels use /dev/ram0 for

the initrd.

...

|
|
|
|
Pseudo-tty's are named as follows:
|
|
* Masters are "pty", slaves are "tty";
|
|
* the fourth letter is one of pqrstuvwxyzabcde indicating
|
|
the 1st through 16th series of 16 pseudo-ttys each, and
|
|
* the fifth letter is one of 0123456789abcdef indicating
|
|
the position within the series.
|
|
|
|
These are the old-style (BSD) PTY devices; Unix98
|
|
devices are on major 128 and above and use the PTY
|
|
master multiplex (/dev/ptmx) to acquire a PTY on
|
|
demand.

5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
|

(any model, u). The use of the capital letters D, H

the drive type is insignificant for these devices.

For Linux/i386, partitions 1-4 are the primary

UART serial ports refer to 8250/16450/16550 series devices.
|
|
|
|
Older versions of the Linux kernel used this major
|
|
number for BSD PTY devices. As of Linux 2.1.115, this
|
|
is no longer supported. Use major numbers 2 and 3.

1 = /dev/lp1 Parallel printer on parport1
|

they are redirected through the parport multiplex layer.

|
|
0 = /dev/loop0 First loop device
|

1 = /dev/loop1 Second loop device
|

The loop devices are used to mount filesystems not
|

associated with block devices. The binding to the

|
loop devices is handled by mount(8) or losetup(8).
|

8 block SCSI disk devices (0-15)

240 = /dev/sdp Sixteenth SCSI disk whole disk
|

Partitions are handled in the same way as for IDE

disks (see major number 3) except that the limit on

partitions is 15.

|
|
225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
|
|
...
|
|
|
|
"No rewind" refers to the omission of the default
|
|
automatic rewind on device close. The MTREW or MTOFFL
|
|
ioctl()'s can be used to rewind the tape regardless of
|
|
the device used to access it.

9 block Metadisk (RAID) devices
|
|
0 = /dev/md0 First metadisk group
|
|
1 = /dev/md1 Second metadisk group

The metadisk driver is used to span a

filesystem across multiple physical disks.

This number is intended for use in sample code, as

|
well as a general "example" device number. It
|
|
should never be used for a device driver that is being
|
|
distributed; either obtain an official number or use
|
|
the local/experimental range. The sudden addition or
|
|
removal of a driver with this number should not cause
|
|
ill effects to the system (bugs excepted.)
|
|
|

IN PARTICULAR, ANY DISTRIBUTION WHICH CONTAINS A
|
|
DEVICE DRIVER USING MAJOR NUMBER 42 IS NONCOMPLIANT.

to mounting filesystems over the net, swapping over

the net, implementing block device in userland etc.

The OnStream SC-x0 SCSI tapes do not support the
|
|
standard SCSI SASD command set and therefore need
|
|
their own driver "osst". Note that the IDE, USB (and
|
|
maybe ParPort) versions may be driven via ide-scsi or
|
|
usb-storage SCSI emulation and this osst device and
|
|
driver as well. The ADR-x0 drives are QIC-157
|
|
compliant and don't need osst.
