| 1313 | Please make sure to pick the right CPU type. Linux/MIPS is not |
| 1314 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will |
| 1315 | *not* work on R4000 machines and vice versa. However, since most |

| 1317 | might be a safe bet. If the resulting kernel does not work, |

| 1536 | Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which |
| 1537 | require workarounds. Without workarounds the system may hang |
| 1538 | unexpectedly. For more information please refer to the gas |
| 1539 | -mfix-loongson2f-nop and -mfix-loongson2f-jump options. |

| 1541 | Loongson 2F03 and later have fixed these issues and no workarounds |
| 1542 | are needed. The workarounds have no significant side effect on them |
| 1543 | but may decrease the performance of the system so this option should |
