This lets you select the page size of the kernel.

8KB and 64KB work quite well, since Sparc ELF sections

provide for up to 64KB alignment.

Therefore, 512KB and 4MB are for expert hackers only.

|

The BBC devices on the UltraSPARC III have two I2C controllers. The
|
|
first I2C controller connects mainly to configuration PROMs (NVRAM,
|
|
CPU configuration, DIMM types, etc.). The second I2C controller
|
|
connects to environmental control devices such as fans and

temperature sensors. The second controller also connects to the

smartcard reader, if present. Say Y to enable support for these.

default y
|
|
---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 :-)

---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.)

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

config PREEMPT

bool "Preemptible Kernel"

help
|
|
This option reduces the latency of the kernel when reacting to
|
|
real-time or interactive events by allowing a low priority process to
|
|
be preempted even if it is in kernel mode executing a system call.
|
|
This allows applications to run more reliably even when the system is
|
|
under load.

Say Y here if you are building a kernel for a desktop, embedded

or real-time system. Say N if you are unsure.

---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.

|
|
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.
