| ---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 |
| default y |
| ---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. |

| ---help--- |
| This enables support for systems with more than one CPU. If you have |
| a system with only one CPU, say N. If you have a system with more |
| than one CPU, say Y. |
| |
| If you say N here, the kernel will run on single and multiprocessor |
| machines, but will use only one CPU of a multiprocessor machine. If |
| you say Y here, the kernel will run on many, but not all, |
| singleprocessor machines. On a singleprocessor machine, the kernel |
| will run faster if you say N here. |
| |
| People using multiprocessor machines who say Y here should also say |
| Y to "Enhanced Real Time Clock Support", below. The "Advanced Power |
| Management" code will be disabled if you say Y here. |

| help |
| SPARC is a family of RISC microprocessors designed and marketed by |
| Sun Microsystems, incorporated. They are very widely found in Sun |
| workstations and clones. This port covers the original 32-bit SPARC; |
| it is old and stable and usually considered one of the "big three" |
| along with the Intel and Alpha ports. The UltraLinux project |
| maintains both the SPARC32 and SPARC64 ports; its web page is |

| ---help--- |
| Say Y here if you want to attach PCMCIA- or PC-cards to your Linux |
| computer. These are credit-card size devices such as network cards, |
| modems or hard drives often used with laptops computers. There are |
| actually two varieties of these cards: the older 16 bit PCMCIA cards |
| and the newer 32 bit CardBus cards. If you want to use CardBus |
| cards, you need to say Y here and also to "CardBus support" below. |
| |
| To use your PC-cards, you will need supporting software from David |
| Hinds' pcmcia-cs package (see the file <file:Documentation/Changes> |
| for location). Please also read the PCMCIA-HOWTO, available from |
| <http://www.tldp.org/docs.html#howto>. |

| config SERIAL_CONSOLE |
| bool |

| ---help--- |
| If you say Y here, it will be possible to use a serial port as the |
| system console (the system console is the device which receives all |
| kernel messages and warnings and which allows logins in single user |
| mode). This could be useful if some terminal or printer is connected |
| to that serial port. |
| |
| Even if you say Y here, the currently visible virtual console |
| (/dev/tty0) will still be used as the system console by default, but |
| you can alter that using a kernel command line option such as |
| "console=ttyS1". (Try "man bootparam" or see the documentation of |
| your boot loader (silo) about how to pass options to the kernel at |
| boot time.) |
| |
| If you don't have a graphics card installed and you say Y here, the |
| kernel will automatically use the first serial line, /dev/ttyS0, as |
| system console. |

| If unsure, say N. |

| menu "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. |
| |
| config UNIX98_PTY_COUNT |
| int "Maximum number of Unix98 PTYs in use (0-2048)" |
| depends on UNIX98_PTYS |
| default "256" |
| help |
| The maximum number of Unix98 PTYs that can be used at any one time. |
| The default is 256, and should be enough for desktop systems. Server |
| machines which support incoming telnet/rlogin/ssh connections and/or |
| serve several X terminals may want to increase this: every incoming |
| connection and every xterm uses up one PTY. |
| |
| When not in use, each additional set of 256 PTYs occupy |
| approximately 8 KB of kernel memory on 32-bit architectures. |
