  3config STDERR_CONSOLE
  4	bool "stderr console"
  5	default y
  6	help
  7	  console driver which dumps all printk messages to stderr.
  8
  9config SSL
 10	bool "Virtual serial line"
 11	help
 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
 14          ttys or ptys.
 15
 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.
 18
 19          Unless you have a specific reason for disabling this, say Y.
 20
 21config NULL_CHAN
 22	bool "null channel support"
 23	help
 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.
 27
 28config PORT_CHAN
 29	bool "port channel support"
 30	help
 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.
 37
 38config PTY_CHAN
 39	bool "pty channel support"
 40	help
 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.
 47
 48config TTY_CHAN
 49	bool "tty channel support"
 50	help
 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.
 56
 57config XTERM_CHAN
 58	bool "xterm channel support"
 59	help
 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
 62          its own xterm.
 63          It is safe to say 'Y' here.
 64
 65config NOCONFIG_CHAN
 66	bool
 67	default !(XTERM_CHAN && TTY_CHAN && PTY_CHAN && PORT_CHAN && NULL_CHAN)
 68
 69config CON_ZERO_CHAN
 70	string "Default main console channel initialization"
 71	default "fd:0,fd:1"
 72	help
 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.
 78
 79config CON_CHAN
 80	string "Default console channel initialization"
 81	default "xterm"
 82	help
 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.
 90
 91config SSL_CHAN
 92	string "Default serial line channel initialization"
 93	default "pty"
 94	help
 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.
102
103config UML_SOUND
104	tristate "Sound support"
105	help
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.
