| 1674 | help |
| 1675 | Choose this option if you want to enable the Extended Physical |
| 1676 | Addressing (XPA) on your MIPS32 core (such as P5600 series). The |
| 1677 | benefit is to increase physical addressing equal to or greater |
| 1678 | than 40 bits. Note that this has the side effect of turning on |
| 1679 | 64-bit addressing which in turn makes the PTEs 64-bit in size. |
| 1680 | If unsure, say 'N' here. |

| 1695 | Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which |
| 1696 | require workarounds. Without workarounds the system may hang |
| 1697 | unexpectedly. For more information please refer to the gas |
| 1698 | -mfix-loongson2f-nop and -mfix-loongson2f-jump options. |
| 1699 | |
| 1700 | Loongson 2F03 and later have fixed these issues and no workarounds |
| 1701 | are needed. The workarounds have no significant side effect on them |
| 1702 | but may decrease the performance of the system so this option should |
| 1703 | be disabled unless the kernel is intended to be run on 2F01 or 2F02 |
| 1704 | systems. |
| 1705 | |
| 1706 | If unsure, please say Y. |
