1415 The workarounds have no significant side effect on them but may
1416 decrease the performance of the system so this option should be

1576 Please make sure to pick the right CPU type. Linux/MIPS is not
1577 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1578 *not* work on R4000 machines and vice versa. However, since most
1579 of the supported machines have an R4000 (or similar) CPU, R4x00
1580 might be a safe bet. If the resulting kernel does not work,
1581 try to recompile with R3000.

1840 help
1841 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1842 require workarounds. Without workarounds the system may hang
1843 unexpectedly. For more information please refer to the gas
1844 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1845
1846 Loongson 2F03 and later have fixed these issues and no workarounds
1847 are needed. The workarounds have no significant side effect on them
1848 but may decrease the performance of the system so this option should
1849 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1850 systems.
1851
1852 If unsure, please say Y.

2166 memory. Default is 40 bits or less, depending on the CPU.
2167 For page sizes 16k and above, this option results in a small

2169 level of page tables is added which imposes both a memory

2491 SmartMIPS is a extension of the MIPS32 architecture aimed at
2492 increased security at both hardware and software level for
2493 smartcards. Enabling this option will allow proper use of the
2494 SmartMIPS instructions by Linux applications. However a kernel with
2495 this option will not work on a MIPS core without SmartMIPS core. If

2962 When this is enabled, the kernel will support use of 64-bit floating
2963 point registers with binaries using the O32 ABI along with the
2964 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2965 32-bit MIPS systems this support is at the cost of increasing the
2966 size and complexity of the compiled FPU emulator. Thus if you are
2967 running a MIPS32 system and know that none of your userland binaries
2968 will require 64-bit floating point, you may wish to reduce the size
2969 of your kernel & potentially improve FP emulation performance by
2970 saying N here.

2974 worked on. In order to avoid userland becoming dependant upon current
2975 behaviour before the details have been finalised, this option should
2976 be considered experimental and only enabled by those working upon
