- menu "UML Character Devices"
- config STDERR_CONSOLE
- bool "stderr console"
- default y
- help
- console driver which dumps all printk messages to stderr.
- config SSL
- bool "Virtual serial line"
- help
- The User-Mode Linux environment allows you to create virtual serial
- lines on the UML that are usually made to show up on the host as
- ttys or ptys.
- See <http://user-mode-linux.sourceforge.net/old/input.html> for more
- information and command line examples of how to use this facility.
- Unless you have a specific reason for disabling this, say Y.
- config NULL_CHAN
- bool "null channel support"
- help
- This option enables support for attaching UML consoles and serial
- lines to a device similar to /dev/null. Data written to it disappears
- and there is never any data to be read.
- config PORT_CHAN
- bool "port channel support"
- help
- This option enables support for attaching UML consoles and serial
- lines to host portals. They may be accessed with 'telnet <host>
- <port number>'. Any number of consoles and serial lines may be
- attached to a single portal, although what UML device you get when
- you telnet to that portal will be unpredictable.
- It is safe to say 'Y' here.
- config PTY_CHAN
- bool "pty channel support"
- help
- This option enables support for attaching UML consoles and serial
- lines to host pseudo-terminals. Access to both traditional
- pseudo-terminals (/dev/pty*) and pts pseudo-terminals are controlled
- with this option. The assignment of UML devices to host devices
- will be announced in the kernel message log.
- It is safe to say 'Y' here.
- config TTY_CHAN
- bool "tty channel support"
- help
- This option enables support for attaching UML consoles and serial
- lines to host terminals. Access to both virtual consoles
- (/dev/tty*) and the slave side of pseudo-terminals (/dev/ttyp* and
- /dev/pts/*) are controlled by this option.
- It is safe to say 'Y' here.
- config XTERM_CHAN
- bool "xterm channel support"
- help
- This option enables support for attaching UML consoles and serial
- lines to xterms. Each UML device so assigned will be brought up in
- its own xterm.
- It is safe to say 'Y' here.
- config NOCONFIG_CHAN
- bool
- default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)
- config CON_ZERO_CHAN
- string "Default main console channel initialization"
- default "fd:0,fd:1"
- help
- This is the string describing the channel to which the main console
- will be attached by default. This value can be overridden from the
- command line. The default value is "fd:0,fd:1", which attaches the
- main console to stdin and stdout.
- It is safe to leave this unchanged.
- config CON_CHAN
- string "Default console channel initialization"
- default "xterm"
- help
- This is the string describing the channel to which all consoles
- except the main console will be attached by default. This value can
- be overridden from the command line. The default value is "xterm",
- which brings them up in xterms.
- It is safe to leave this unchanged, although you may wish to change
- this if you expect the UML that you build to be run in environments
- which don't have X or xterm available.
- config SSL_CHAN
- string "Default serial line channel initialization"
- default "pty"
- help
- This is the string describing the channel to which the serial lines
- will be attached by default. This value can be overridden from the
- command line. The default value is "pty", which attaches them to
- traditional pseudo-terminals.
- It is safe to leave this unchanged, although you may wish to change
- this if you expect the UML that you build to be run in environments
- which don't have a set of /dev/pty* devices.
- config UML_SOUND
- tristate "Sound support"
- help
- This option enables UML sound support. If enabled, it will pull in
- soundcore and the UML hostaudio relay, which acts as a intermediary
- between the host's dsp and mixer devices and the UML sound system.
- It is safe to say 'Y' here.
- config SOUND
- tristate
- default UML_SOUND
- config SOUND_OSS_CORE
