 * Option: ARM_AMBA
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)


 * Option: ISA
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * Find out whether you have ISA slots on your motherboard. ISA is the name of a bus system, i.e. the way the CPU talks to the other stuff inside your box.  Other bus systems are PCI, EISA, MicroChannel (MCA) or VESA.  ISA is an older system, now being displaced by PCI; newer boards don't support it.  If you have ISA, say Y, otherwise N.

 * Option: PCI
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) PCI support if ARCH_INTEGRATOR_AP || ARCH_VERSATILE_PB
 * Find out whether you have a PCI motherboard. PCI is the name of a bus system, i.e. the way the CPU talks to the other stuff inside your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or VESA. If you have PCI, say Y, otherwise N.
 * The PCI-HOWTO, available from , contains valuable information about which PCI hardware does work under Linux and which doesn't.

 * Kernel Versions: 2.6.15.6 ...
 * (on/off)

 * Option: Howto configure the Linux kernel/drivers/pcmcia

Kernel Features

 * Option: SMP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Symmetric Multi-Processing (EXPERIMENTAL)
 * depends on EXPERIMENTAL && REALVIEW_MPCORE
 * This enables support for systems with more than one CPU. If you have a system with only one CPU, like most personal computers, 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, single processor machines. On a single processor machine, the kernel will run faster if you say N here.
 * See also the , ,  and the SMP-HOWTO available at .
 * If you don't know what to do here, say N.

"Maximum number of CPUs (2-32)" 2 32
 * Option: NR_CPUS
 * Kernel Versions: 2.6.15.6 ...
 * depends on SMP
 * default "4"


 * Option: HOTPLUG_CPU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Support for hot-pluggable CPUs (EXPERIMENTAL)
 * depends on SMP && HOTPLUG && EXPERIMENTAL
 * Say Y here to experiment with turning CPUs off and on. CPUs can be controlled through /sys/devices/system/cpu.


 * Option: LOCAL_TIMERS
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Use local timer interrupts
 * depends on SMP && REALVIEW_MPCORE
 * default y
 * Enable support for local timers on SMP platforms, rather than the legacy IPI broadcast method. Local timers allows the system accounting to be spread across the timer interval, preventing a thundering herd at every timer tick.


 * Option: PREEMPT
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Preemptible Kernel (EXPERIMENTAL)
 * depends on EXPERIMENTAL
 * 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.


 * Option: NO_IDLE_HZ
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Dynamic tick timer
 * Select this option if you want to disable continuous timer ticks and have them programmed to occur as required. This option saves power as the system can remain in idle state for longer.
 * By default dynamic tick is disabled during the boot, and can be manually enabled with:
 * echo 1 > /sys/devices/system/timer/timer0/dyn_tick
 * Alternatively, if you want dynamic tick automatically enabled during boot, pass "dyntick=enable" via the kernel command string.
 * Please note that dynamic tick may affect the accuracy of timekeeping on some platforms depending on the implementation. Currently at least OMAP, PXA2xx and SA11x0 platforms are known to have accurate timekeeping with dynamic tick.


 * Option: ARCH_DISCONTIGMEM_ENABLE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default (ARCH_LH7A40X && !LH7A40X_CONTIGMEM)
 * Say Y to support efficient handling of discontiguous physical memory, for architectures which are either NUMA (Non-Uniform Memory Access) or have huge holes in the physical address space for other reasons. See  for more.


 * Option: Howto configure the Linux kernel/mm


 * Option: LEDS
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Timer and CPU usage LEDs
 * depends on ARCH_CDB89712 || ARCH_CO285 || ARCH_EBSA110 || \  ARCH_EBSA285 || ARCH_IMX || ARCH_INTEGRATOR || \  ARCH_LUBBOCK || MACH_MAINSTONE || ARCH_NETWINDER || \  ARCH_OMAP || ARCH_P720T || ARCH_PXA_IDP || \  ARCH_SA1100 || ARCH_SHARK || ARCH_VERSATILE
 * 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.


 * Option: LEDS_TIMER
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Timer LED if (!ARCH_CDB89712 && !ARCH_OMAP) || \   MACH_OMAP_H2 || MACH_OMAP_PERSEUS2
 * depends on LEDS
 * default y if ARCH_EBSA110
 * 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.

!ARCH_OMAP) || MACH_OMAP_H2 || MACH_OMAP_PERSEUS2
 * Option: LEDS_CPU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) CPU usage LED if (!ARCH_CDB89712 && !ARCH_EBSA110 && \
 * depends on LEDS
 * 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 functions. You may choose to use both, but the Timer LED function will overrule the CPU usage LED.


 * Option: ALIGNMENT_TRAP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default y if !ARCH_EBSA110
 * 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.

Boot options

 * Compressed boot loader in ROM. Yes, we really want to ask about
 * TEXT and BSS so we preserve their values in the config files.

"Compressed ROM boot loader base address"
 * Option: ZBOOT_ROM_TEXT
 * Kernel Versions: 2.6.15.6 ...
 * default "0"
 * The physical address at which the ROM-able zImage is to be placed in the target. Platforms which normally make use of ROM-able zImage formats normally set this to a suitable value in their defconfig file.
 * If ZBOOT_ROM is not enabled, this has no effect.

"Compressed ROM boot loader BSS address"
 * Option: ZBOOT_ROM_BSS
 * Kernel Versions: 2.6.15.6 ...
 * default "0"
 * The base address of 64KiB of read/write memory in the target for the ROM-able zImage, which must be available while the decompressor is running. Platforms which normally make use of ROM-able zImage formats normally set this to a suitable value in their defconfig file.
 * If ZBOOT_ROM is not enabled, this has no effect.


 * Option: ZBOOT_ROM
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Compressed boot loader in ROM/flash
 * depends on ZBOOT_ROM_TEXT != ZBOOT_ROM_BSS
 * Say Y here if you intend to execute your compressed kernel image (zImage) directly from ROM or flash. If unsure, say N.

"Default kernel command string"
 * Option: CMDLINE
 * Kernel Versions: 2.6.15.6 ...
 * default ""
 * 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).


 * Option: XIP_KERNEL
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Kernel Execute-In-Place from ROM
 * depends on !ZBOOT_ROM
 * Execute-In-Place allows the kernel to run from non-volatile storage directly addressable by the CPU, such as NOR flash. This saves RAM space since the text section of the kernel is not loaded from flash to RAM. Read-write sections, such as the data section and stack, are still copied to RAM.  The XIP kernel is not compressed since it has to run directly from flash, so it will take more space to store it.  The flash address used to link the kernel object files, and for storing it, is configuration dependent. Therefore, if you say Y here, you must know the proper physical address where to store the kernel image depending on your own flash memory usage.
 * Also note that the make target becomes "make xipImage" rather than make zImage or make Image. The final kernel binary to put in ROM memory will be arch/arm/boot/xipImage.
 * If unsure, say N.

"XIP Kernel Physical Location"
 * Option: XIP_PHYS_ADDR
 * Kernel Versions: 2.6.15.6 ...
 * depends on XIP_KERNEL
 * default "0x00080000"
 * This is the physical address in your flash memory the kernel will be linked for and stored to. This address is dependent on your own flash usage.

(ARCH_SA1100 || ARCH_INTEGRATOR || ARCH_OMAP1)

CPU Frequency scaling

 * Option: Howto configure the Linux kernel/drivers/cpufreq


 * Option: CPU_FREQ_SA1100
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * depends on CPU_FREQ && (SA1100_H3100 || SA1100_H3600 || SA1100_H3800 || SA1100_LART || SA1100_PLEB || SA1100_BADGE4 || SA1100_HACKKIT)
 * default y


 * Option: CPU_FREQ_SA1110
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * depends on CPU_FREQ && (SA1100_ASSABET || SA1100_CERF || SA1100_PT_SYSTEM3)
 * default y


 * Option: CPU_FREQ_INTEGRATOR
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) CPUfreq driver for ARM Integrator CPUs
 * depends on ARCH_INTEGRATOR && CPU_FREQ
 * default y
 * This enables the CPUfreq driver for ARM Integrator CPUs.
 * For details, take a look at .
 * If in doubt, say Y.

Floating point emulation
"At least one emulation must be selected"


 * Option: FPE_NWFPE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) NWFPE math emulation
 * Say Y to include the NWFPE floating point emulator in the kernel. This is necessary to run most binaries. Linux does not currently support floating point hardware so you need to say Y here even if your machine has an FPA or floating point co-processor podule.
 * You may say N here if you are going to load the Acorn FPEmulator early in the bootup.


 * Option: FPE_NWFPE_XP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Support extended precision
 * depends on FPE_NWFPE
 * 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.


 * Option: FPE_FASTFPE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) FastFPE math emulation (EXPERIMENTAL)
 * depends on !CPU_32v3 && EXPERIMENTAL
 * 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.


 * Option: VFP
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) VFP-format floating point maths
 * depends on CPU_V6 || CPU_ARM926T
 * Say Y to include VFP support code in the kernel. This is needed if your hardware includes a VFP unit.
 * Please see  for release notes and additional status information.
 * Say N if your target does not have VFP hardware.

Userspace binary formats

 * Option: Howto configure the Linux kernel/fs.binfmt"


 * Option: ARTHUR
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) RISC OS personality
 * 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).

Power management options

 * Option: Howto configure the Linux kernel/kernel/power


 * Option: APM
 * Kernel Versions: 2.6.15.6 ...
 * (on/off/module) Advanced Power Management Emulation
 * depends on PM_LEGACY
 * 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).
 * In order to use APM, you will need supporting software. For location and more information, read  and the Battery Powered Linux mini-HOWTO, available from .
 * 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.
 * 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).
