32 .Nd introduction to pmppc special files and hardware support
34 This section describes the special files, related driver functions,
35 and networking support available in the system.
36 In this part of the manual, the
38 section of each configurable device gives a sample specification
39 for use in constructing a system description for the
44 section lists messages which may appear on the console
45 and/or in the system error log
47 due to errors in device operation;
52 This section contains both devices
53 which may be configured into the system
54 and network related information.
55 The networking support is introduced in
57 .Sh PMPPC DEVICE SUPPORT
58 This section describes the hardware supported on the
61 Software support for these devices comes in two forms.
62 A hardware device may be supported with a character or block
64 or it may be used within the networking subsystem and have a
65 .Em network interface driver .
66 Block and character devices are accessed through files in the file
67 system of a special type; see
69 Network interfaces are indirectly accessed through the interprocess
70 communication facilities provided by the system; see
73 A hardware device is identified to the system at configuration time
74 and the appropriate device or network interface driver is then compiled
76 When the resultant system is booted, the
77 autoconfiguration facilities in the system probe for the device
78 and, if found, enable the software support for it.
79 If a device does not respond at autoconfiguration
80 time it is not accessible at any time afterwards.
81 To enable a device which did not autoconfigure,
82 the system will have to be rebooted.
84 The autoconfiguration system is described in
86 A list of the supported devices is given below.
97 man page first appeared in
100 The devices listed below are supported in this incarnation of
102 Devices are indicated by their functional interface.
103 Not all supported devices are listed.
105 PCI devices are supported through the
107 bus and associated devices.
109 USB devices are supported through the
111 bus and associated devices.
113 Additionally, the following specific devices are supported:
114 .Bl -tag -width "xxxxxxxx" -compact -offset indent
116 serial ports in the CPC700
118 PCI host controller CPC700
122 Real Time Clock driver
