7 console driver which dumps all printk messages to stderr.
10 bool "Virtual serial line"
12 The User-Mode Linux environment allows you to create virtual serial
13 lines on the UML that are usually made to show up on the host as
16 See <http://user-mode-linux.sourceforge.net/old/input.html> for more
17 information and command line examples of how to use this facility.
19 Unless you have a specific reason for disabling this, say Y.
22 bool "null channel support"
24 This option enables support for attaching UML consoles and serial
25 lines to a device similar to /dev/null. Data written to it disappears
26 and there is never any data to be read.
29 bool "port channel support"
31 This option enables support for attaching UML consoles and serial
32 lines to host portals. They may be accessed with 'telnet <host>
33 <port number>'. Any number of consoles and serial lines may be
34 attached to a single portal, although what UML device you get when
35 you telnet to that portal will be unpredictable.
36 It is safe to say 'Y' here.
39 bool "pty channel support"
41 This option enables support for attaching UML consoles and serial
42 lines to host pseudo-terminals. Access to both traditional
43 pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled
44 with this option. The assignment of UML devices to host devices
45 will be announced in the kernel message log.
46 It is safe to say 'Y' here.
49 bool "tty channel support"
51 This option enables support for attaching UML consoles and serial
52 lines to host terminals. Access to both virtual consoles
53 (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and
54 /dev/pts/*) are controlled by this option.
55 It is safe to say 'Y' here.
58 bool "xterm channel support"
60 This option enables support for attaching UML consoles and serial
61 lines to xterms. Each UML device so assigned will be brought up in
63 It is safe to say 'Y' here.
67 default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)
70 string "Default main console channel initialization"
73 This is the string describing the channel to which the main console
74 will be attached by default. This value can be overridden from the
75 command line. The default value is "fd:0,fd:1", which attaches the
76 main console to stdin and stdout.
77 It is safe to leave this unchanged.
80 string "Default console channel initialization"
83 This is the string describing the channel to which all consoles
84 except the main console will be attached by default. This value can
85 be overridden from the command line. The default value is "xterm",
86 which brings them up in xterms.
87 It is safe to leave this unchanged, although you may wish to change
88 this if you expect the UML that you build to be run in environments
89 which don't have X or xterm available.
92 string "Default serial line channel initialization"
95 This is the string describing the channel to which the serial lines
96 will be attached by default. This value can be overridden from the
97 command line. The default value is "pty", which attaches them to
98 traditional pseudo-terminals.
99 It is safe to leave this unchanged, although you may wish to change
100 this if you expect the UML that you build to be run in environments
101 which don't have a set of /dev/pty* devices.
104 tristate "Sound support"
106 This option enables UML sound support. If enabled, it will pull in
107 soundcore and the UML hostaudio relay, which acts as a intermediary
108 between the host's dsp and mixer devices and the UML sound system.
109 It is safe to say 'Y' here.
