6 intro - introduction to special files and hardware support
7
9 This section describes the special files, related driver functions, and
10 networking support available in the system. In this part of the man‐
11 ual, the SYNOPSIS section of each configurable device gives a sample
12 specification for use in constructing a system description for the
13 /sys/conf/configscript, the autoconfig(8), program and descibes the
14 major and minor device numbers and their encoding. The DIAGNOSTICS
15 section lists messages which may appear on the console and/or in the
16 system error log /usr/adm/messages due to errors in device operation.
17 This section contains both devices which may be configured into the
19 system, ``4'' entries, and network related information, ``4N'', ``4P'',
20 and ``4F'' entries; The networking support is introduced in intro(4N).

23 This section describes the hardware supported on the DEC PDP-11. Soft‐
24 ware support for these devices comes in two forms. A hardware device
25 may be supported with a character or block device driver, or it may be
26 used within the networking subsystem and have a network interface
27 driver. Block and character devices are accessed through files in the
28 file system of a special type; c.f. mknod(8). Network interfaces are
29 indirectly accessed through the interprocess communication facilities
30 provided by the system; see socket(2).
31 A hardware device is identified to the system at configuration time and
33 the appropriate device or network interface driver is then compiled
34 into the system. When the resultant system is booted, the autoconfigu‐
35 ration facilities in the system probe for the device on either the
36 UNIBUS (or Q-bus) or MASSBUS and, if found, enable the software support
37 for it. If a device does not respond at autoconfiguration time it is
38 not accessible at any time afterwards. To enable a device which did
39 not autoconfigure, the system will have to be rebooted.
40 The autoconfiguration system is described in autoconfig(8). A list of
42 the supported devices is given below.

45 intro(4), networking(4), config(8).

48 The devices listed below are supported in this incarnation of the sys‐
49 tem. Pseudo-devices are not listed. Listed also are devices which are
50 in various stages of porting to 2.11BSD from 4.3BSD.
51 Devices are indicated by their functional interface. If second vendor
53 products provide functionally identical interfaces they should be
54 usable with the supplied software. (Beware, however, that we promise
55 the software works ONLY with the hardware indicated on the appropriate
56 manual page.) Occasionally, new devices of a similar type may be added
57 simply by creating appropriate table entries in the driver.
