36 .Nd introduction to sparc64 special files and hardware support
38 This section describes the special files, related driver functions,
39 and networking support
40 available in the system.
41 In this part of the manual, the
44 each configurable device gives a sample specification
45 for use in constructing a system description for the
50 section lists messages which may appear on the console
51 and/or in the system error log
53 due to errors in device operation;
58 This section contains both devices
59 which may be configured into the system
60 and network related information.
61 The networking support is introduced in
64 This section describes the hardware supported on the SPARC64
66 Software support for these devices comes in two forms. A hardware
67 device may be supported with a character or block
69 or it may be used within the networking subsystem and have a
70 .Em network interface driver .
71 Block and character devices are accessed through files in the file
72 system of a special type; see
74 Network interfaces are indirectly accessed through the interprocess
75 communication facilities provided by the system; see
78 A hardware device is identified to the system at configuration time
79 and the appropriate device or network interface driver is then compiled
80 into the system. When the resultant system is booted, the
81 autoconfiguration facilities in the system probe for the device
82 and, if found, enable the software support for it.
83 If a device does not respond at autoconfiguration
84 time it is not accessible at any time afterwards.
85 To enable a device which did not autoconfigure,
86 the system must be rebooted.
88 The autoconfiguration system is described in
90 A list of the supported devices is given below.
110 The devices listed below are supported in this incarnation of
111 the system. Devices are indicated by their functional interface.
112 Not all supported devices are listed.
