7 console driver which dumps all printk messages to stderr.
14 bool "Virtual serial line"
16 The User-Mode Linux environment allows you to create virtual serial
17 lines on the UML that are usually made to show up on the host as
20 See <http://user-mode-linux.sourceforge.net/old/input.html> for more
21 information and command line examples of how to use this facility.
23 Unless you have a specific reason for disabling this, say Y.
26 bool "null channel support"
28 This option enables support for attaching UML consoles and serial
29 lines to a device similar to /dev/null. Data written to it disappears
30 and there is never any data to be read.
33 bool "port channel support"
35 This option enables support for attaching UML consoles and serial
36 lines to host portals. They may be accessed with 'telnet <host>
37 <port number>'. Any number of consoles and serial lines may be
38 attached to a single portal, although what UML device you get when
39 you telnet to that portal will be unpredictable.
40 It is safe to say 'Y' here.
43 bool "pty channel support"
45 This option enables support for attaching UML consoles and serial
46 lines to host pseudo-terminals. Access to both traditional
47 pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled
48 with this option. The assignment of UML devices to host devices
49 will be announced in the kernel message log.
50 It is safe to say 'Y' here.
53 bool "tty channel support"
55 This option enables support for attaching UML consoles and serial
56 lines to host terminals. Access to both virtual consoles
57 (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and
58 /dev/pts/*) are controlled by this option.
59 It is safe to say 'Y' here.
62 bool "xterm channel support"
64 This option enables support for attaching UML consoles and serial
65 lines to xterms. Each UML device so assigned will be brought up in
67 It is safe to say 'Y' here.
71 default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)
74 string "Default main console channel initialization"
77 This is the string describing the channel to which the main console
78 will be attached by default. This value can be overridden from the
79 command line. The default value is "fd:0,fd:1", which attaches the
80 main console to stdin and stdout.
81 It is safe to leave this unchanged.
84 string "Default console channel initialization"
87 This is the string describing the channel to which all consoles
88 except the main console will be attached by default. This value can
89 be overridden from the command line. The default value is "xterm",
90 which brings them up in xterms.
91 It is safe to leave this unchanged, although you may wish to change
92 this if you expect the UML that you build to be run in environments
93 which don't have X or xterm available.
96 string "Default serial line channel initialization"
99 This is the string describing the channel to which the serial lines
100 will be attached by default. This value can be overridden from the
101 command line. The default value is "pty", which attaches them to
102 traditional pseudo-terminals.
103 It is safe to leave this unchanged, although you may wish to change
104 this if you expect the UML that you build to be run in environments
105 which don't have a set of /dev/pty* devices.
108 tristate "Sound support"
110 This option enables UML sound support. If enabled, it will pull in
111 soundcore and the UML hostaudio relay, which acts as a intermediary
112 between the host's dsp and mixer devices and the UML sound system.
113 It is safe to say 'Y' here.
