+config VT
+ bool "Virtual terminal"
+ ---help---
+ If you say Y here, you will get support for terminal devices with
+ display and keyboard devices. These are called "virtual" because you
+ can run several virtual terminals (also called virtual consoles) on
+ one physical terminal. This is rather useful, for example one
+ virtual terminal can collect system messages and warnings, another
+ one can be used for a text-mode user session, and a third could run
+ an X session, all in parallel. Switching between virtual terminals
+ is done with certain key combinations, usually Alt-<function key>.
+
+ The setterm command ("man setterm") can be used to change the
+ properties (such as colors or beeping) of a virtual terminal. The
+ man page console_codes(4) ("man console_codes") contains the special
+ character sequences that can be used to change those properties
+ directly. The fonts used on virtual terminals can be changed with
+ the setfont ("man setfont") command and the key bindings are defined
+ with the loadkeys ("man loadkeys") command.
+
+ You need at least one virtual terminal device in order to make use
+ of your keyboard and monitor. Therefore, only people configuring an
+ embedded system would want to say N here in order to save some
+ memory; the only way to log into such a system is then via a serial
+ or network connection.
+
+ If unsure, say Y, or else you won't be able to do much with your new
+ shiny Linux system :-)
+
+config VT_CONSOLE
+ bool "Support for console on virtual terminal"
+ depends on VT
+ ---help---
+ The system console is the device which receives all kernel messages
+ and warnings and which allows logins in single user mode. If you
+ answer Y here, a virtual terminal (the device used to interact with
+ a physical terminal) can be used as system console. This is the most
+ common mode of operations, so you should say Y here unless you want
+ the kernel messages be output only to a serial port (in which case
+ you should say Y to "Console on serial port", below).
+
+ If you do say Y here, by default the currently visible virtual
+ terminal (/dev/tty0) will be used as system console. You can change
+ that with a kernel command line option such as "console=tty3" which
+ would use the third virtual terminal as system console. (Try "man
+ bootparam" or see the documentation of your boot loader (lilo or
+ loadlin) about how to pass options to the kernel at boot time.)
+
+ If unsure, say Y.

+comment "Unix98 PTY support"
+
+config UNIX98_PTYS
+ bool "Unix98 PTY support"
+ ---help---
+ A pseudo terminal (PTY) is a software device consisting of two
+ halves: a master and a slave. The slave device behaves identical to
+ a physical terminal; the master device is used by a process to
+ read data from and write data to the slave, thereby emulating a
+ terminal. Typical programs for the master side are telnet servers
+ and xterms.
+
+ Linux has traditionally used the BSD-like names /dev/ptyxx for
+ masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
+ has a number of problems. The GNU C library glibc 2.1 and later,
+ however, supports the Unix98 naming standard: in order to acquire a
+ pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
+ terminal is then made available to the process and the pseudo
+ terminal slave can be accessed as /dev/pts/<number>. What was
+ traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
+
+ The entries in /dev/pts/ are created on the fly by a virtual
+ file system; therefore, if you say Y here you should say Y to
+ "/dev/pts file system for Unix98 PTYs" as well.
+
+ If you want to say Y here, you need to have the C library glibc 2.1
+ or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
+ Read the instructions in <file:Documentation/Changes> pertaining to
+ pseudo terminals. It's safe to say N.

+/* Core file format: The core file is written in such a way that gdb
+ can understand it and provide useful information to the user (under
+ linux we use the 'trad-core' bfd). There are quite a number of
+ obstacles to being able to view the contents of the floating point
+ registers, and until these are solved you will not be able to view the
+ contents of them. Actually, you can read in the core file and look at
+ the contents of the user struct to find out what the floating point
+ registers contain.
+ The actual file contents are as follows:
+ UPAGE: 1 page consisting of a user struct that tells gdb what is present
+ in the file. Directly after this is a copy of the task_struct, which
+ is currently not used by gdb, but it may come in useful at some point.
+ All of the registers are stored as part of the upage. The upage should
+ always be only one page.
+ DATA: The data area is stored. We use current->end_text to
+ current->brk to pick up all of the user variables, plus any memory
+ that may have been malloced. No attempt is made to determine if a page
+ is demand-zero or if a page is totally unused, we just cover the entire
+ range. All of the addresses are rounded in such a way that an integral
+ number of pages is written.
+ STACK: We need the stack information in order to get a meaningful
+ backtrace. We need to write the data from (esp) to
+ current->start_stack, so we round each of these off in order to be able
+ to write an integer number of pages.
+ The minimum core file size is 3 pages, or 12288 bytes.
