1335 Please make sure to pick the right CPU type. Linux/MIPS is not
1336 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1337 *not* work on R4000 machines and vice versa. However, since most
1338 of the supported machines have an R4000 (or similar) CPU, R4x00
1339 might be a safe bet. If the resulting kernel does not work,
1340 try to recompile with R3000.

1560 unexpectedly. For more information please refer to the gas
1561 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1562
1563 Loongson 2F03 and later have fixed these issues and no workarounds
1564 are needed. The workarounds have no significant side effect on them
1565 but may decrease the performance of the system so this option should
1566 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1567 systems.

2431 kexec is a system call that implements the ability to shutdown your

2488 When this is enabled, the kernel will support use of 64-bit floating
2489 point registers with binaries using the O32 ABI along with the
2490 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2491 32-bit MIPS systems this support is at the cost of increasing the
2492 size and complexity of the compiled FPU emulator. Thus if you are
2493 running a MIPS32 system and know that none of your userland binaries
2494 will require 64-bit floating point, you may wish to reduce the size
2495 of your kernel & potentially improve FP emulation performance by
2496 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002498 Although binutils currently supports use of this flag the details
2499 concerning its effect upon the O32 ABI in userland are still being
2500 worked on. In order to avoid userland becoming dependant upon current
2501 behaviour before the details have been finalised, this option should
2502 be considered experimental and only enabled by those working upon
2503 said details.
