23 SPARC is a family of RISC microprocessors designed and marketed by
24 Sun Microsystems, incorporated. They are very widely found in Sun
25 workstations and clones. This port covers the original 32-bit SPARC;
26 it is old and stable and usually considered one of the "big three"
27 along with the Intel and Alpha ports. The UltraLinux project
28 maintains both the SPARC32 and SPARC64 ports; its web page is
29 available at <http://www.ultralinux.org/>.

67 This enables support for systems with more than one CPU. If you have
68 a system with only one CPU, say N. If you have a system with more
71 If you say N here, the kernel will run on single and multiprocessor
72 machines, but will use only one CPU of a multiprocessor machine. If
73 you say Y here, the kernel will run on many, but not all,
74 singleprocessor machines. On a singleprocessor machine, the kernel
75 will run faster if you say N here.
77 People using multiprocessor machines who say Y here should also say
78 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
79 Management" code will be disabled if you say Y here.
81 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
82 available at <http://www.tldp.org/docs.html#howto>.

98 ISA is found on Espresso only and is not supported currently.
104 EISA is not supported.
110 MCA is not supported.
116 Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
117 computer. These are credit-card size devices such as network cards,
118 modems or hard drives often used with laptops computers. There are
119 actually two varieties of these cards: the older 16 bit PCMCIA cards
120 and the newer 32 bit CardBus cards. If you want to use CardBus
121 cards, you need to say Y here and also to "CardBus support" below.
123 To use your PC-cards, you will need supporting software from David
124 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
125 for location). Please also read the PCMCIA-HOWTO, available from
126 <http://www.tldp.org/docs.html#howto>.
128 To compile this driver as modules, choose M here: the
129 modules will be called pcmcia_core and ds.
139 config SERIAL_CONSOLE
143 If you say Y here, it will be possible to use a serial port as the
144 system console (the system console is the device which receives all
145 kernel messages and warnings and which allows logins in single user
146 mode). This could be useful if some terminal or printer is connected
149 Even if you say Y here, the currently visible virtual console
150 (/dev/tty0) will still be used as the system console by default, but
151 you can alter that using a kernel command line option such as
152 "console=ttyS1". (Try "man bootparam" or see the documentation of
153 your boot loader (silo) about how to pass options to the kernel at
156 If you don't have a graphics card installed and you say Y here, the
157 kernel will automatically use the first serial line, /dev/ttyS0, as

205 Sparc32 does not have a CAS instruction like sparc64. cmpxchg()
206 is emulated, and therefore it is not completely atomic.

216 bool "Support for PCI and PS/2 keyboard/mouse"
218 CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
219 CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC.
220 All of these platforms are extremely obscure, so say N if unsure.

227 config SUN_OPENPROMFS
228 tristate "Openprom tree appears in /proc/openprom"
230 If you say Y, the OpenPROM device tree will be available as a
231 virtual file system, which you can mount to /proc/openprom by "mount
232 -t openpromfs none /proc/openprom".
234 To compile the /proc/openprom support as a module, choose M here: the
235 module will be called openpromfs.
237 Only choose N if you know in advance that you will not need to modify
238 OpenPROM settings on the running system.
241 tristate "Sun4m LED driver"
243 This driver toggles the front-panel LED on sun4m systems
244 in a user-specifiable manner. Its state can be probed
245 by reading /proc/led and its blinking mode can be changed
246 via writes to /proc/led
