792 This option supports all of the Octeon reference boards from Cavium
793 Networks. It builds a kernel that dynamically determines the Octeon
794 CPU type and supports all known board reference implementations.
795 Some of the supported boards are:
796 EBT3000
797 EBH3000
798 EBH3100
799 Thunder
800 Kodama
801 Hikari

1347 Please make sure to pick the right CPU type. Linux/MIPS is not
1348 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1349 *not* work on R4000 machines and vice versa. However, since most
1350 of the supported machines have an R4000 (or similar) CPU, R4x00
1351 might be a safe bet. If the resulting kernel does not work,
1352 try to recompile with R3000.

1575 Loongson 2F03 and later have fixed these issues and no workarounds
1576 are needed. The workarounds have no significant side effect on them
1577 but may decrease the performance of the system so this option should

2434 kexec is a system call that implements the ability to shutdown your

2491 When this is enabled, the kernel will support use of 64-bit floating
2492 point registers with binaries using the O32 ABI along with the
2493 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2494 32-bit MIPS systems this support is at the cost of increasing the
2495 size and complexity of the compiled FPU emulator. Thus if you are
2496 running a MIPS32 system and know that none of your userland binaries
2497 will require 64-bit floating point, you may wish to reduce the size
2498 of your kernel & potentially improve FP emulation performance by
2499 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002501 Although binutils currently supports use of this flag the details
2502 concerning its effect upon the O32 ABI in userland are still being
2503 worked on. In order to avoid userland becoming dependant upon current
2504 behaviour before the details have been finalised, this option should
2505 be considered experimental and only enabled by those working upon
2506 said details.
