13 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 14 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 15 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 16 | manufactured, but legacy ARM-based PC hardware remains popular in |
1da177e4 LT |

31 | The Extended Industry Standard Architecture (EISA) bus was | |
32 | developed as an open alternative to the IBM MicroChannel bus. | |
33 | ||
34 | The EISA bus provided some of the features of the IBM MicroChannel | |
35 | bus while maintaining backward compatibility with cards made for | |
36 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
37 | 1995 when it was made obsolete by the PCI bus. | |

485 | Enable support for local timers on SMP platforms, rather then the | |
486 | legacy IPI broadcast method. Local timers allows the system | |
487 | accounting to be spread across the timer interval, preventing a | |
488 | "thundering herd" at every timer tick. | |

490 | config PREEMPT |
491 | bool "Preemptible Kernel (EXPERIMENTAL)" | |
492 | depends on EXPERIMENTAL | |
493 | help | |
494 | This option reduces the latency of the kernel when reacting to | |
495 | real-time or interactive events by allowing a low priority process to | |
496 | be preempted even if it is in kernel mode executing a system call. | |
497 | This allows applications to run more reliably even when the system is | |
498 | under load. | |
499 | ||
500 | Say Y here if you are building a kernel for a desktop, embedded | |
501 | or real-time system. Say N if you are unsure. | |

503 | config NO_IDLE_HZ |
504 | bool "Dynamic tick timer" | |
505 | help | |
506 | Select this option if you want to disable continuous timer ticks | |
507 | and have them programmed to occur as required. This option saves | |
508 | power as the system can remain in idle state for longer. | |
509 | ||
510 | By default dynamic tick is disabled during the boot, and can be | |
511 | manually enabled with: | |
512 | ||
513 | echo 1 > /sys/devices/system/timer/timer0/dyn_tick | |
514 | ||
515 | Alternatively, if you want dynamic tick automatically enabled | |
516 | during boot, pass "dyntick=enable" via the kernel command string. | |
517 | ||

518 | Please note that dynamic tick may affect the accuracy of |
519 | timekeeping on some platforms depending on the implementation. | |
569d2c34 NP |
520 | Currently at least OMAP, PXA2xx and SA11x0 platforms are known |
521 | to have accurate timekeeping with dynamic tick. | |

530 | config AEABI |
531 | bool "Use the ARM EABI to compile the kernel" | |
532 | help | |
533 | This option allows for the kernel to be compiled using the latest | |
534 | ARM ABI (aka EABI). This is only useful if you are using a user | |
535 | space environment that is also compiled with EABI. | |
536 | ||
537 | Since there are major incompatibilities between the legacy ABI and | |
538 | EABI, especially with regard to structure member alignment, this | |
539 | option also changes the kernel syscall calling convention to | |
540 | disambiguate both ABIs and allow for backward compatibility support | |
541 | (selected with CONFIG_OABI_COMPAT). | |
542 | ||
543 | To use this you need GCC version 4.0.0 or later. | |

6c90c872 NP |
548 | default y |
549 | help | |
550 | This option preserves the old syscall interface along with the | |
551 | new (ARM EABI) one. It also provides a compatibility layer to | |
552 | intercept syscalls that have structure arguments which layout | |
553 | in memory differs between the legacy ABI and the new ARM EABI | |
554 | (only for non "thumb" binaries). This option adds a tiny | |
555 | overhead to all syscalls and produces a slightly larger kernel. | |
556 | If you know you'll be using only pure EABI user space then you | |
557 | can say N here. If this option is not selected and you attempt | |
558 | to execute a legacy ABI binary then the result will be | |
559 | UNPREDICTABLE (in fact it can be predicted that it won't work | |
560 | at all). If in doubt say Y. | |
