1219 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1220 | *not* work on R4000 machines and vice versa. However, since most | |

1612 | SMTC pseudo-interrupts between TCs are deferred and queued | |
1613 | if the target TC is interrupt-inhibited (IXMT). In the first | |
1614 | SMTC prototypes, these queued IPIs were serviced on return | |

1616 | INSTANT_REPLAY option dispatches them as part of local_irq_restore() | |
1617 | processing, which adds runtime overhead (hence the option to turn | |

2028 | The Extended Industry Standard Architecture (EISA) bus was | |
2029 | developed as an open alternative to the IBM MicroChannel bus. | |
2030 | ||
2031 | The EISA bus provided some of the features of the IBM MicroChannel | |
2032 | bus while maintaining backward compatibility with cards made for | |
2033 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2034 | 1995 when it was made obsolete by the PCI bus. | |
2035 | ||
2036 | Say Y here if you are building a kernel for an EISA-based machine. | |
2037 | ||
2038 | Otherwise, say N. | |

2078 | help |
2079 | A 64-bit kernel is usually built using the 64-bit ELF binary object | |
2080 | format as it's one that allows arbitrary 64-bit constructs. For | |
2081 | kernels that are loaded within the KSEG compatibility segments the | |
2082 | 32-bit ELF format can optionally be used resulting in a somewhat | |
2083 | smaller binary, but this option is not explicitly supported by the | |
2084 | toolchain and since binutils 2.14 it does not even work at all. | |
2085 | ||
