1312 Please make sure to pick the right CPU type. Linux/MIPS is not
1313 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1314 *not* work on R4000 machines and vice versa. However, since most
1315 of the supported machines have an R4000 (or similar) CPU, R4x00
1316 might be a safe bet. If the resulting kernel does not work,
1317 try to recompile with R3000.

1537 unexpectedly. For more information please refer to the gas
1538 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1539
1540 Loongson 2F03 and later have fixed these issues and no workarounds
1541 are needed. The workarounds have no significant side effect on them
1542 but may decrease the performance of the system so this option should
1543 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1544 systems.

2407 kexec is a system call that implements the ability to shutdown your
2408 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002409 but it is independent of the system firmware. And like a reboot

Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002412 The name comes from the similarity to the exec system call.

2464 When this is enabled, the kernel will support use of 64-bit floating
2465 point registers with binaries using the O32 ABI along with the
2466 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2467 32-bit MIPS systems this support is at the cost of increasing the
2468 size and complexity of the compiled FPU emulator. Thus if you are
2469 running a MIPS32 system and know that none of your userland binaries
2470 will require 64-bit floating point, you may wish to reduce the size
2471 of your kernel & potentially improve FP emulation performance by
2472 saying N here.
2473
Paul Burton06e2e882014-02-14 17:55:18 +00002474 Although binutils currently supports use of this flag the details
2475 concerning its effect upon the O32 ABI in userland are still being
2476 worked on. In order to avoid userland becoming dependant upon current
2477 behaviour before the details have been finalised, this option should
2478 be considered experimental and only enabled by those working upon
2479 said details.
