1561 Choose this option to build a kernel for release 6 or later of the
1562 MIPS64 architecture. New MIPS processors, starting with the Warrior
1563 family, are based on a MIPS64r6 processor. If you own an older
1564 processor, you probably need to select MIPS64r1 or MIPS64r2 instead.

1574 Please make sure to pick the right CPU type. Linux/MIPS is not
1575 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1576 *not* work on R4000 machines and vice versa. However, since most
1577 of the supported machines have an R4000 (or similar) CPU, R4x00
1578 might be a safe bet. If the resulting kernel does not work,
1579 try to recompile with R3000.

1819 Choose this option if you want to enable the Extended Physical
1820 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1821 benefit is to increase physical addressing equal to or greater
1822 than 40 bits. Note that this has the side effect of turning on
1823 64-bit addressing which in turn makes the PTEs 64-bit in size.
1824 If unsure, say 'N' here.

1839 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1840 require workarounds. Without workarounds the system may hang
1841 unexpectedly. For more information please refer to the gas
1842 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1843
1844 Loongson 2F03 and later have fixed these issues and no workarounds
1845 are needed. The workarounds have no significant side effect on them
1846 but may decrease the performance of the system so this option should
1847 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1848 systems.
1849
1850 If unsure, please say Y.

2965 point registers with binaries using the O32 ABI along with the
2966 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2967 32-bit MIPS systems this support is at the cost of increasing the
2968 size and complexity of the compiled FPU emulator. Thus if you are
2969 running a MIPS32 system and know that none of your userland binaries

2971 of your kernel & potentially improve FP emulation performance by
