SPARC is a family of RISC microprocessors designed and marketed by
Sun Microsystems, incorporated. They are very widely found in Sun
workstations and clones.
Say yes to build a 64-bit kernel - formerly known as sparc64

---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.
See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
available at <http://www.tldp.org/docs.html#howto>.
If you don't know what to do here, say N.

This lets you select the page size of the kernel.

provide for up to 64KB alignment.

bool "Enable seccomp to safely compute untrusted bytecode"
depends on SPARC64 && PROC_FS
default y
help
This kernel feature is useful for number crunching applications
that may need to compute untrusted bytecode during their
execution. By using pipes or other transports made available to
the process as file descriptors supporting the read/write
syscalls, it's possible to isolate those applications in
their own address space using seccomp. Once seccomp is
enabled via /proc/<pid>/seccomp, it cannot be disabled
and the task is only allowed to execute a few safe syscalls
defined by each seccomp mode.
If unsure, say Y. Only embedded should say N here.

Say Y here if you want to be able to pass default arguments to
the kernel. This will be overridden by the bootloader, if you
use one (such as SILO). This is most useful if you want to boot
a kernel from TFTP, and want default options to be available
with having them passed on the command line.
NOTE: This option WILL override the PROM bootargs setting!

config SERIAL_CONSOLE
bool
depends on SPARC32
default y
---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.
config SPARC_LEON
bool "Sparc Leon processor family"

---help---
If you say Y here if you are running on a SPARC-LEON processor.
The LEON processor is a synthesizable VHDL model of the
SPARC-v8 standard. LEON is part of the GRLIB collection of
IP cores that are distributed under GPL. GRLIB can be downloaded
from www.gaisler.com. You can download a sparc-linux cross-compilation
toolchain at www.gaisler.com.

help
Find out whether your system includes a PCI bus. PCI is the name of
a bus system, i.e. the way the CPU talks to the other stuff inside
your box. If you say Y here, the kernel will include drivers and
infrastructure code to support PCI bus devices.
CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC.
All of these platforms are extremely obscure, so say N if unsure.

To compile the /proc/openprom support as a module, choose M here: the
module will be called openpromfs.
Only choose N if you know in advance that you will not need to modify
OpenPROM settings on the running system.
