This enables support for systems with more than one CPU. If you have

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

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
|
|
available at <http://www.ultralinux.org/>.

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>.

To compile this driver as modules, choose M here: the

modules will be called pcmcia_core and ds.

---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.

|

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.

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.
