The ARM series is a line of low-power-consumption RISC chip designs
licensed by ARM ltd and targeted at embedded applications and
handhelds such as the Compaq IPAQ. ARM-based PCs are no longer
manufactured, but legacy ARM-based PC hardware remains popular in
Europe. There is an ARM Linux project with a web page at
<http://www.arm.linux.org.uk/>.
config MMU
bool
default y
config EISA
bool
---help---
The Extended Industry Standard Architecture (EISA) bus was
developed as an open alternative to the IBM MicroChannel bus.
The EISA bus provided some of the features of the IBM MicroChannel
bus while maintaining backward compatibility with cards made for
the older ISA bus. The EISA bus saw limited use between 1988 and
1995 when it was made obsolete by the PCI bus.
Say Y here if you are building a kernel for an EISA-based machine.
Otherwise, say N.
config SBUS
bool
config MCA
bool

MicroChannel Architecture is found in some IBM PS/2 machines and
laptops. It is a bus system similar to PCI or ISA. See
<file:Documentation/mca.txt> (and especially the web page given
there) before attempting to build an MCA bus kernel.

CPU clock scaling allows you to change the clock speed of the
running CPU on the fly. This is a nice method to save battery power,
because the lower the clock speed, the less power the CPU
consumes. Note that this driver doesn't automatically change the CPU
clock speed, you need some userland tools (which still have to be
written) to implement the policy. If you don't understand what this
is all about, it's safe to say 'N'.

help
Say Y to include 80-bit support in the kernel floating-point
emulator. Otherwise, only 32 and 64-bit support is compiled in.
Note that gcc does not generate 80-bit operations by default,
so in most cases this option only enlarges the size of the
floating point emulator without any good reason.
You almost surely want to say N here.
config FPE_FASTFPE
bool "FastFPE math emulation (EXPERIMENTAL)"
depends on !CPU_32v3 && EXPERIMENTAL
---help---
Say Y here to include the FAST floating point emulator in the kernel.
This is an experimental much faster emulator which now also has full
precision for the mantissa. It does not support any exceptions.
It is very simple, and approximately 3-6 times faster than NWFPE.
It should be sufficient for most programs. It may be not suitable
for scientific calculations, but you have to check this for yourself.
If you do not feel you need a faster FP emulation you should better
choose NWFPE.
config VFP
bool "VFP-format floating point maths"
help
Say Y to include VFP support code in the kernel. This is needed
if your hardware includes a VFP unit.
Please see <file:Documentation/arm/VFP/release-notes.txt> for
release notes and additional status information.
Say N if your target does not have VFP hardware.

config PM
bool "Power Management support"
---help---
"Power Management" means that parts of your computer are shut
off or put into a power conserving "sleep" mode if they are not
being used. There are two competing standards for doing this: APM
and ACPI. If you want to use either one, say Y here and then also
to the requisite support below.
Power Management is most important for battery powered laptop
computers; if you have a laptop, check out the Linux Laptop home
page on the WWW at <http://www.linux-on-laptops.com/> or
Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>
and the Battery Powered Linux mini-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
Note that, even if you say N here, Linux on the x86 architecture
will issue the hlt instruction if nothing is to be done, thereby
sending the processor to sleep and saving power.
config PREEMPT
bool "Preemptible Kernel (EXPERIMENTAL)"
depends on CPU_32 && EXPERIMENTAL
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.
config APM
tristate "Advanced Power Management Emulation"
depends on PM
---help---
APM is a BIOS specification for saving power using several different
techniques. This is mostly useful for battery powered laptops with
APM compliant BIOSes. If you say Y here, the system time will be
reset after a RESUME operation, the /proc/apm device will provide
battery status information, and user-space programs will receive
notification of APM "events" (e.g. battery status change).
If you select "Y" here, you can disable actual use of the APM
BIOS by passing the "apm=off" option to the kernel at boot time.
Note that the APM support is almost completely disabled for
machines with more than one CPU.
In order to use APM, you will need supporting software. For location
and more information, read <file:Documentation/pm.txt> and the
Battery Powered Linux mini-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
This driver does not spin down disk drives (see the hdparm(8)
manpage ("man 8 hdparm") for that), and it doesn't turn off
VESA-compliant "green" monitors.
This driver does not support the TI 4000M TravelMate and the ACER
486/DX4/75 because they don't have compliant BIOSes. Many "green"
desktop machines also don't have compliant BIOSes, and this driver
may cause those machines to panic during the boot phase.
Generally, if you don't have a battery in your machine, there isn't
much point in using this driver and you should say N. If you get
random kernel OOPSes or reboots that don't seem to be related to
anything, try disabling/enabling this option (or disabling/enabling
APM in your BIOS).
Some other things you should try when experiencing seemingly random,
"weird" problems:
1) make sure that you have enough swap space and that it is
enabled.
2) pass the "no-hlt" option to the kernel
3) switch on floating point emulation in the kernel and pass
the "no387" option to the kernel
4) pass the "floppy=nodma" option to the kernel
5) pass the "mem=4M" option to the kernel (thereby disabling
all but the first 4 MB of RAM)
6) make sure that the CPU is not over clocked.
7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
8) disable the cache from your BIOS settings
9) install a fan for the video card or exchange video RAM
10) install a better fan for the CPU
11) exchange RAM chips
12) exchange the motherboard.
To compile this driver as a module, choose M here: the
module will be called apm.
config ARTHUR
tristate "RISC OS personality"
depends on CPU_32
help
Say Y here to include the kernel code necessary if you want to run
Acorn RISC OS/Arthur binaries under Linux. This code is still very
experimental; if this sounds frightening, say N and sleep in peace.
You can also say M here to compile this support as a module (which
will be called arthur).
config CMDLINE
string "Default kernel command string"
default ""
help
On some architectures (EBSA110 and CATS), there is currently no way
for the boot loader to pass arguments to the kernel. For these
architectures, you should supply some command-line options at build
time by entering them here. As a minimum, you should specify the
memory size and the root device (e.g., mem=64M root=/dev/nfs).

help
If you say Y here, the LEDs on your machine will be used
to provide useful information about your current system status.
If you are compiling a kernel for a NetWinder or EBSA-285, you will
be able to select which LEDs are active using the options below. If
you are compiling a kernel for the EBSA-110 or the LART however, the
red LED will simply flash regularly to indicate that the system is
still functional. It is safe to say Y here if you have a CATS
system, but the driver will do nothing.

help
If you say Y here, one of the system LEDs (the green one on the
NetWinder, the amber one on the EBSA285, or the red one on the LART)
will flash regularly to indicate that the system is still
operational. This is mainly useful to kernel hackers who are
debugging unstable kernels.
The LART uses the same LED for both Timer LED and CPU usage LED
functions. You may choose to use both, but the Timer LED function
will overrule the CPU usage LED.
config LEDS_CPU

If you say Y here, the red LED will be used to give a good real
time indication of CPU usage, by lighting whenever the idle task
is not currently executing.
The LART uses the same LED for both Timer LED and CPU usage LED

config ALIGNMENT_TRAP
bool
depends on CPU_32
default y if !ARCH_EBSA110
help
ARM processors can not fetch/store information which is not
naturally aligned on the bus, i.e., a 4 byte fetch must start at an
address divisible by 4. On 32-bit ARM processors, these non-aligned
fetch/store instructions will be emulated in software if you say
here, which has a severe performance impact. This is necessary for
correct operation of some network protocols. With an IP-only
configuration it is safe to say N, otherwise say Y.

config FRAME_POINTER
bool
default y
help
If you say N here, the resulting kernel will be slightly smaller and
faster. However, when a problem occurs with the kernel, the
information that is reported is severely limited. Most people
should say Y here.
config DEBUG_USER
bool "Verbose user fault messages"
help
When a user program crashes due to an exception, the kernel can
print a brief message explaining what the problem was. This is
sometimes helpful for debugging but serves no purpose on a
production system. Most people should say N here.
In addition, you need to pass user_debug=N on the kernel command
line to enable this feature. N consists of the sum of:
1 - undefined instruction events
2 - system calls
4 - invalid data aborts
8 - SIGSEGV faults
16 - SIGBUS faults
config DEBUG_INFO
bool "Include GDB debugging information in kernel binary"
help
Say Y here to include source-level debugging information in the
`vmlinux' binary image. This is handy if you want to use gdb or
addr2line to debug the kernel. It has no impact on the in-memory
footprint of the running kernel but it can increase the amount of
time and disk space needed for compilation of the kernel. If in
doubt say N.

allocation as well as poisoning memory on free to catch use of freed
memory.
config MAGIC_SYSRQ
bool "Magic SysRq key"
depends on DEBUG_KERNEL
help
If you say Y here, you will have some control over the system even
if the system crashes for example during kernel debugging (e.g., you
will be able to flush the buffer cache to disk, reboot the system
immediately or dump some status information). This is accomplished
by pressing various keys while holding SysRq (Alt+PrintScreen). It
also works on a serial console (on PC hardware at least), if you
send a BREAK and then within 5 seconds a command keypress. The
keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
unless you really know what this hack does.
config DEBUG_SPINLOCK
bool "Spinlock debugging"

debugging but costs about 70-100K of memory.
config DEBUG_ERRORS
bool "Verbose kernel error messages"
depends on DEBUG_KERNEL
help
This option controls verbose debugging information which can be
printed when the kernel detects an internal error. This debugging
information is useful to kernel hackers when tracking down problems,
