471 | Qemu is a software emulator which among other architectures also | |
472 | can simulate a MIPS32 4Kc system. This patch adds support for the | |
473 | system architecture that currently is being simulated by Qemu. It | |
474 | will eventually be removed again when Qemu has the capability to | |
475 | simulate actual MIPS hardware platforms. More information on Qemu | |

1439 | This allows you to specify the maximum number of CPUs which this | |
1440 | kernel will support. The maximum supported value is 32 for 32-bit | |
1441 | kernel and 64 for 64-bit kernels; the minimum value which makes | |
1442 | sense is 2. | |
1443 | ||
1444 | This is purely to save memory - each supported CPU adds | |
1445 | approximately eight kilobytes to the kernel image. | |

1450 | This option reduces the latency of the kernel when reacting to | |
1451 | real-time or interactive events by allowing a low priority process to | |
1452 | be preempted even if it is in kernel mode executing a system call. | |
