396 | Qemu is a software emulator which among other architectures also |
397 | can simulate a MIPS32 4Kc system. This patch adds support for the | |
398 | system architecture that currently is being simulated by Qemu. It | |
399 | will eventually be removed again when Qemu has the capability to | |
400 | simulate actual MIPS hardware platforms. More information on Qemu | |
401 | can be found at http://www.linux-mips.org/wiki/Qemu. | |

1626 | This enables support for systems with more than one CPU. If you have |
1627 | a system with only one CPU, like most personal computers, say N. If | |
1628 | you have a system with more than one CPU, say Y. | |
1629 | ||
1630 | If you say N here, the kernel will run on single and multiprocessor | |
1631 | machines, but will use only one CPU of a multiprocessor machine. If | |
1632 | you say Y here, the kernel will run on many, but not all, | |
1633 | singleprocessor machines. On a singleprocessor machine, the kernel | |
1634 | will run faster if you say N here. | |
1635 | ||
1636 | People using multiprocessor machines who say Y here should also say | |
1637 | Y to "Enhanced Real Time Clock Support", below. | |
