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

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

578 depends on SMP && REALVIEW_MPCORE
581 Enable support for local timers on SMP platforms, rather then the
582 legacy IPI broadcast method. Local timers allows the system
583 accounting to be spread across the timer interval, preventing a
584 "thundering herd" at every timer tick.
587 bool "Preemptible Kernel (EXPERIMENTAL)"
588 depends on EXPERIMENTAL
590 This option reduces the latency of the kernel when reacting to
591 real-time or interactive events by allowing a low priority process to
592 be preempted even if it is in kernel mode executing a system call.
593 This allows applications to run more reliably even when the system is

597 or real-time system. Say N if you are unsure.
600 bool "Dynamic tick timer"
601 depends on !GENERIC_CLOCKEVENTS
603 Select this option if you want to disable continuous timer ticks
604 and have them programmed to occur as required. This option saves
605 power as the system can remain in idle state for longer.
607 By default dynamic tick is disabled during the boot, and can be
608 manually enabled with:
610 echo 1 > /sys/devices/system/timer/timer0/dyn_tick
612 Alternatively, if you want dynamic tick automatically enabled
613 during boot, pass "dyntick=enable" via the kernel command string.
615 Please note that dynamic tick may affect the accuracy of
616 timekeeping on some platforms depending on the implementation.
617 Currently at least OMAP, PXA2xx and SA11x0 platforms are known
618 to have accurate timekeeping with dynamic tick.

628 bool "Use the ARM EABI to compile the kernel"
630 This option allows for the kernel to be compiled using the latest
631 ARM ABI (aka EABI). This is only useful if you are using a user
632 space environment that is also compiled with EABI.
634 Since there are major incompatibilities between the legacy ABI and
635 EABI, especially with regard to structure member alignment, this
636 option also changes the kernel syscall calling convention to
637 disambiguate both ABIs and allow for backward compatibility support
638 (selected with CONFIG_OABI_COMPAT).
640 To use this you need GCC version 4.0.0 or later.
643 bool "Allow old ABI binaries to run with this kernel (EXPERIMENTAL)"
644 depends on AEABI && EXPERIMENTAL
647 This option preserves the old syscall interface along with the
648 new (ARM EABI) one. It also provides a compatibility layer to
649 intercept syscalls that have structure arguments which layout
650 in memory differs between the legacy ABI and the new ARM EABI
651 (only for non "thumb" binaries). This option adds a tiny
652 overhead to all syscalls and produces a slightly larger kernel.
653 If you know you'll be using only pure EABI user space then you
654 can say N here. If this option is not selected and you attempt
655 to execute a legacy ABI binary then the result will be
656 UNPREDICTABLE (in fact it can be predicted that it won't work
657 at all). If in doubt say Y.

705 operational. This is mainly useful to kernel hackers who are
706 debugging unstable kernels.

730 ARM processors cannot fetch/store information which is not

733 fetch/store instructions will be emulated in software if you say
734 here, which has a severe performance impact. This is necessary for
735 correct operation of some network protocols. With an IP-only

762 entire decompressed kernel plus an additional 128 KiB.
763 Platforms which normally make use of ROM-able zImage formats

773 (zImage) directly from ROM or flash. If unsure, say N.
776 string "Default kernel command string"
779 On some architectures (EBSA110 and CATS), there is currently no way
780 for the boot loader to pass arguments to the kernel. For these
781 architectures, you should supply some command-line options at build
782 time by entering them here. As a minimum, you should specify the
783 memory size and the root device (e.g., mem=64M root=/dev/nfs).
786 bool "Kernel Execute-In-Place from ROM"
787 depends on !ZBOOT_ROM
789 Execute-In-Place allows the kernel to run from non-volatile storage
790 directly addressable by the CPU, such as NOR flash. This saves RAM
791 space since the text section of the kernel is not loaded from flash
792 to RAM. Read-write sections, such as the data section and stack,
793 are still copied to RAM. The XIP kernel is not compressed since
794 it has to run directly from flash, so it will take more space to
795 store it. The flash address used to link the kernel object files,
796 and for storing it, is configuration dependent. Therefore, if you
797 say Y here, you must know the proper physical address where to
798 store the kernel image depending on your own flash memory usage.
800 Also note that the make target becomes "make xipImage" rather than
801 "make zImage" or "make Image". The final kernel binary to put in
802 ROM memory will be arch/arm/boot/xipImage.
