22 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 23 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 24 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 25 | manufactured, but legacy ARM-based PC hardware remains popular in |
1da177e4 LT |
26 | Europe. There is an ARM Linux project with a web page at |

63 | The Extended Industry Standard Architecture (EISA) bus was | |
64 | developed as an open alternative to the IBM MicroChannel bus. | |
65 | ||
66 | The EISA bus provided some of the features of the IBM MicroChannel | |
67 | bus while maintaining backward compatibility with cards made for | |
68 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
69 | 1995 when it was made obsolete by the PCI bus. | |

859 | bool "Use the ARM EABI to compile the kernel" | |
860 | help | |
861 | This option allows for the kernel to be compiled using the latest | |
862 | ARM ABI (aka EABI). This is only useful if you are using a user | |
863 | space environment that is also compiled with EABI. | |
864 | ||
865 | Since there are major incompatibilities between the legacy ABI and | |
866 | EABI, especially with regard to structure member alignment, this | |
867 | option also changes the kernel syscall calling convention to | |
868 | disambiguate both ABIs and allow for backward compatibility support | |
869 | (selected with CONFIG_OABI_COMPAT). | |
870 | ||
871 | To use this you need GCC version 4.0.0 or later. | |

878 | This option preserves the old syscall interface along with the | |
879 | new (ARM EABI) one. It also provides a compatibility layer to | |
880 | intercept syscalls that have structure arguments which layout | |
881 | in memory differs between the legacy ABI and the new ARM EABI | |
882 | (only for non "thumb" binaries). This option adds a tiny | |
883 | overhead to all syscalls and produces a slightly larger kernel. | |
884 | If you know you'll be using only pure EABI user space then you | |
885 | can say N here. If this option is not selected and you attempt | |
886 | to execute a legacy ABI binary then the result will be | |
887 | UNPREDICTABLE (in fact it can be predicted that it won't work | |
888 | at all). If in doubt say Y. | |
