777 | Some MIPS machines can be configured for either little or big endian | |
5e83d430 | 778 | byte order. These modes require different kernels and a different |
3cb2fccc | 779 | Linux distribution. In general there is one preferred byteorder for a |
5e83d430 | 780 | particular system but some systems are just as commonly used in the |
3dde6ad8 | 781 | one or the other endianness. |

1620 | This allows you to specify the maximum number of CPUs which this | |
1621 | kernel will support. The maximum supported value is 32 for 32-bit | |
1622 | kernel and 64 for 64-bit kernels; the minimum value which makes | |

1623 | sense is 1 for Qemu (useful only for kernel debugging purposes) |
1624 | and 2 for all others. | |

1626 | This is purely to save memory - each supported CPU adds | |
72ede9b1 AN |
1627 | approximately eight kilobytes to the kernel image. For best |
1628 | performance should round up your number of processors to the next | |
1629 | power of two. | |
