Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

33 If you say Y here, you will get support for terminal devices with
34 display and keyboard devices. These are called "virtual" because you
35 can run several virtual terminals (also called virtual consoles) on
36 one physical terminal. This is rather useful, for example one
37 virtual terminal can collect system messages and warnings, another
38 one can be used for a text-mode user session, and a third could run
39 an X session, all in parallel. Switching between virtual terminals
40 is done with certain key combinations, usually Alt-<function key>.
41
42 The setterm command ("man setterm") can be used to change the
43 properties (such as colors or beeping) of a virtual terminal. The
44 man page console_codes(4) ("man console_codes") contains the special
45 character sequences that can be used to change those properties
46 directly. The fonts used on virtual terminals can be changed with
47 the setfont ("man setfont") command and the key bindings are defined
48 with the loadkeys ("man loadkeys") command.
49
50 You need at least one virtual terminal device in order to make use
51 of your keyboard and monitor. Therefore, only people configuring an
52 embedded system would want to say N here in order to save some
53 memory; the only way to log into such a system is then via a serial
54 or network connection.
55
56 If unsure, say Y, or else you won't be able to do much with your new
57 shiny Linux system :-)

59config VT_CONSOLE

61 default y
62 ---help---
63 The system console is the device which receives all kernel messages
64 and warnings and which allows logins in single user mode. If you
65 answer Y here, a virtual terminal (the device used to interact with
66 a physical terminal) can be used as system console. This is the most
67 common mode of operations, so you should say Y here unless you want
68 the kernel messages be output only to a serial port (in which case
69 you should say Y to "Console on serial port", below).
70
71 If you do say Y here, by default the currently visible virtual
72 terminal (/dev/tty0) will be used as system console. You can change
73 that with a kernel command line option such as "console=tty3" which
74 would use the third virtual terminal as system console. (Try "man
75 bootparam" or see the documentation of your boot loader (lilo or
76 loadlin) about how to pass options to the kernel at boot time.)

89 a system with only one CPU, say N. If you have a system with more
90 than one CPU, say Y.
91
92 If you say N here, the kernel will run on single and multiprocessor
93 machines, but will use only one CPU of a multiprocessor machine. If
94 you say Y here, the kernel will run on many, but not all,
95 singleprocessor machines. On a singleprocessor machine, the kernel
96 will run faster if you say N here.
97
98 People using multiprocessor machines who say Y here should also say
99 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
100 Management" code will be disabled if you say Y here.

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

149 Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
150 computer. These are credit-card size devices such as network cards,
151 modems or hard drives often used with laptops computers. There are
152 actually two varieties of these cards: the older 16 bit PCMCIA cards
153 and the newer 32 bit CardBus cards. If you want to use CardBus
154 cards, you need to say Y here and also to "CardBus support" below.
155
156 To use your PC-cards, you will need supporting software from David
157 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
158 for location). Please also read the PCMCIA-HOWTO, available from
159 <http://www.tldp.org/docs.html#howto>.

177 system console (the system console is the device which receives all
178 kernel messages and warnings and which allows logins in single user
179 mode). This could be useful if some terminal or printer is connected
180 to that serial port.
181
182 Even if you say Y here, the currently visible virtual console
183 (/dev/tty0) will still be used as the system console by default, but
184 you can alter that using a kernel command line option such as
185 "console=ttyS1". (Try "man bootparam" or see the documentation of
186 your boot loader (silo) about how to pass options to the kernel at
187 boot time.)

276 Also read the Printing-HOWTO, available from
277 <http://www.tldp.org/docs.html#howto>.
278
279 It is possible to share one parallel port among several devices
280 (e.g. printer and ZIP drive) and it is safe to compile the
281 corresponding drivers into the kernel. If you want to compile this
282 driver as a module however, choose M here and read
283 <file:Documentation/parport.txt>. The module will be called lp.
284
285 If you have several parallel ports, you can specify which ports to
286 use with the "lp" kernel command line option. (Try "man bootparam"
287 or see the documentation of your boot loader (silo) about how to pass
288 options to the kernel at boot time.) The syntax of the "lp" command
289 line option can be found in <file:drivers/char/lp.c>.
290
291 If you have more than 8 printers, you need to increase the LP_NO
292 macro in lp.c and the PARPORT_MAX macro in parport.h.

332 bool "Unix98 PTY support"
333 ---help---
334 A pseudo terminal (PTY) is a software device consisting of two
335 halves: a master and a slave. The slave device behaves identical to
336 a physical terminal; the master device is used by a process to
337 read data from and write data to the slave, thereby emulating a
338 terminal. Typical programs for the master side are telnet servers
339 and xterms.
340
341 Linux has traditionally used the BSD-like names /dev/ptyxx for
342 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
343 has a number of problems. The GNU C library glibc 2.1 and later,
344 however, supports the Unix98 naming standard: in order to acquire a
345 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
346 terminal is then made available to the process and the pseudo
347 terminal slave can be accessed as /dev/pts/<number>. What was
348 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
349
350 The entries in /dev/pts/ are created on the fly by a virtual
351 file system; therefore, if you say Y here you should say Y to
352 "/dev/pts file system for Unix98 PTYs" as well.
353
354 If you want to say Y here, you need to have the C library glibc 2.1
355 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
356 Read the instructions in <file:Documentation/Changes> pertaining to
357 pseudo terminals. It's safe to say N.

364 The maximum number of Unix98 PTYs that can be used at any one time.

366 machines which support incoming telnet/rlogin/ssh connections and/or
367 serve several X terminals may want to increase this: every incoming
368 connection and every xterm uses up one PTY.
369
370 When not in use, each additional set of 256 PTYs occupy
371 approximately 8 KB of kernel memory on 32-bit architectures.
