1457 Please make sure to pick the right CPU type. Linux/MIPS is not
1458 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1459 *not* work on R4000 machines and vice versa. However, since most
1460 of the supported machines have an R4000 (or similar) CPU, R4x00
1461 might be a safe bet. If the resulting kernel does not work,
1462 try to recompile with R3000.

1691 benefit is to increase physical addressing equal to or greater

1693 64-bit addressing which in turn makes the PTEs 64-bit in size.

1709 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1710 require workarounds. Without workarounds the system may hang
1711 unexpectedly. For more information please refer to the gas
1712 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1713
1714 Loongson 2F03 and later have fixed these issues and no workarounds
1715 are needed. The workarounds have no significant side effect on them
1716 but may decrease the performance of the system so this option should
1717 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1718 systems.

2679 When this is enabled, the kernel will support use of 64-bit floating
2680 point registers with binaries using the O32 ABI along with the
2681 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2682 32-bit MIPS systems this support is at the cost of increasing the
2683 size and complexity of the compiled FPU emulator. Thus if you are
2684 running a MIPS32 system and know that none of your userland binaries
2685 will require 64-bit floating point, you may wish to reduce the size
2686 of your kernel & potentially improve FP emulation performance by
2687 saying N here.

2691 worked on. In order to avoid userland becoming dependant upon current

2693 be considered experimental and only enabled by those working upon
2694 said details.
