47 The Extended Industry Standard Architecture (EISA) bus was
48 developed as an open alternative to the IBM MicroChannel bus.
50 The EISA bus provided some of the features of the IBM MicroChannel
51 bus while maintaining backward compatibility with cards made for
52 the older ISA bus. The EISA bus saw limited use between 1988 and
53 1995 when it was made obsolete by the PCI bus.
55 Say Y here if you are building a kernel for an EISA-based machine.
65 MicroChannel Architecture is found in some IBM PS/2 machines and
66 laptops. It is a bus system similar to PCI or ISA. See

598 you have a system with more than one CPU, say Y.
600 If you say N here, the kernel will run on single and multiprocessor
601 machines, but will use only one CPU of a multiprocessor machine. If
602 you say Y here, the kernel will run on many, but not all, single

624 can be controlled through /sys/devices/system/cpu.
627 bool "Use local timer interrupts"
628 depends on SMP && REALVIEW_MPCORE
631 Enable support for local timers on SMP platforms, rather then the
632 legacy IPI broadcast method. Local timers allows the system
633 accounting to be spread across the timer interval, preventing a
634 "thundering herd" at every timer tick.
637 bool "Preemptible Kernel (EXPERIMENTAL)"
638 depends on EXPERIMENTAL
640 This option reduces the latency of the kernel when reacting to
641 real-time or interactive events by allowing a low priority process to
642 be preempted even if it is in kernel mode executing a system call.
643 This allows applications to run more reliably even when the system is

647 or real-time system. Say N if you are unsure.
650 bool "Dynamic tick timer"
651 depends on !GENERIC_CLOCKEVENTS
653 Select this option if you want to disable continuous timer ticks
654 and have them programmed to occur as required. This option saves
655 power as the system can remain in idle state for longer.
657 By default dynamic tick is disabled during the boot, and can be
658 manually enabled with:
660 echo 1 > /sys/devices/system/timer/timer0/dyn_tick
662 Alternatively, if you want dynamic tick automatically enabled
663 during boot, pass "dyntick=enable" via the kernel command string.
665 Please note that dynamic tick may affect the accuracy of
666 timekeeping on some platforms depending on the implementation.
667 Currently at least OMAP, PXA2xx and SA11x0 platforms are known
668 to have accurate timekeeping with dynamic tick.

679 bool "Use the ARM EABI to compile the kernel"
681 This option allows for the kernel to be compiled using the latest
682 ARM ABI (aka EABI). This is only useful if you are using a user
683 space environment that is also compiled with EABI.
685 Since there are major incompatibilities between the legacy ABI and
686 EABI, especially with regard to structure member alignment, this
687 option also changes the kernel syscall calling convention to
688 disambiguate both ABIs and allow for backward compatibility support
689 (selected with CONFIG_OABI_COMPAT).
691 To use this you need GCC version 4.0.0 or later.
694 bool "Allow old ABI binaries to run with this kernel (EXPERIMENTAL)"
695 depends on AEABI && EXPERIMENTAL
698 This option preserves the old syscall interface along with the
699 new (ARM EABI) one. It also provides a compatibility layer to
700 intercept syscalls that have structure arguments which layout
701 in memory differs between the legacy ABI and the new ARM EABI
702 (only for non "thumb" binaries). This option adds a tiny
703 overhead to all syscalls and produces a slightly larger kernel.
704 If you know you'll be using only pure EABI user space then you
705 can say N here. If this option is not selected and you attempt
706 to execute a legacy ABI binary then the result will be

827 Say Y here if you intend to execute your compressed kernel image
828 (zImage) directly from ROM or flash. If unsure, say N.
831 string "Default kernel command string"
834 On some architectures (EBSA110 and CATS), there is currently no way
835 for the boot loader to pass arguments to the kernel. For these
836 architectures, you should supply some command-line options at build
837 time by entering them here. As a minimum, you should specify the
838 memory size and the root device (e.g., mem=64M root=/dev/nfs).
841 bool "Kernel Execute-In-Place from ROM"
842 depends on !ZBOOT_ROM
844 Execute-In-Place allows the kernel to run from non-volatile storage
845 directly addressable by the CPU, such as NOR flash. This saves RAM
846 space since the text section of the kernel is not loaded from flash
847 to RAM. Read-write sections, such as the data section and stack,
848 are still copied to RAM. The XIP kernel is not compressed since
849 it has to run directly from flash, so it will take more space to
850 store it. The flash address used to link the kernel object files,
851 and for storing it, is configuration dependent. Therefore, if you
852 say Y here, you must know the proper physical address where to
853 store the kernel image depending on your own flash memory usage.
855 Also note that the make target becomes "make xipImage" rather than
856 "make zImage" or "make Image". The final kernel binary to put in
857 ROM memory will be arch/arm/boot/xipImage.

866 This is the physical address in your flash memory the kernel will

874 kexec is a system call that implements the ability to shutdown your

876 but it is independent of the system firmware. And like a reboot
877 you can start any kernel with it, not just Linux.

935 This is necessary to run most binaries. Linux does not currently
936 support floating point hardware so you need to say Y here even if
937 your machine has an FPA or floating point co-processor podule.
939 You may say N here if you are going to load the Acorn FPEmulator
943 bool "Support extended precision"
946 Say Y to include 80-bit support in the kernel floating-point
947 emulator. Otherwise, only 32 and 64-bit support is compiled in.
948 Note that gcc does not generate 80-bit operations by default,
949 so in most cases this option only enlarges the size of the
950 floating point emulator without any good reason.
952 You almost surely want to say N here.
955 bool "FastFPE math emulation (EXPERIMENTAL)"
956 depends on (!AEABI || OABI_COMPAT) && !CPU_32v3 && EXPERIMENTAL
958 Say Y here to include the FAST floating point emulator in the kernel.
959 This is an experimental much faster emulator which now also has full
960 precision for the mantissa. It does not support any exceptions.
961 It is very simple, and approximately 3-6 times faster than NWFPE.
963 It should be sufficient for most programs. It may be not suitable
964 for scientific calculations, but you have to check this for yourself.
965 If you do not feel you need a faster FP emulation you should better
969 bool "VFP-format floating point maths"
970 depends on CPU_V6 || CPU_ARM926T || CPU_V7
972 Say Y to include VFP support code in the kernel. This is needed
973 if your hardware includes a VFP unit.
975 Please see <file:Documentation/arm/VFP/release-notes.txt> for
976 release notes and additional status information.
978 Say N if your target does not have VFP hardware.
986 bool "Advanced SIMD (NEON) Extension support"
987 depends on VFPv3 && CPU_V7
989 Say Y to include support code for NEON, the ARMv7 Advanced SIMD

999 tristate "RISC OS personality"
1002 Say Y here to include the kernel code necessary if you want to run
1003 Acorn RISC OS/Arthur binaries under Linux. This code is still very
1004 experimental; if this sounds frightening, say N and sleep in peace.
1005 You can also say M here to compile this support as a module (which
1006 will be called arthur).
