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

1345 Please make sure to pick the right CPU type. Linux/MIPS is not
1346 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1347 *not* work on R4000 machines and vice versa. However, since most
1348 of the supported machines have an R4000 (or similar) CPU, R4x00
1349 might be a safe bet. If the resulting kernel does not work,
1350 try to recompile with R3000.

1573 Loongson 2F03 and later have fixed these issues and no workarounds
1574 are needed. The workarounds have no significant side effect on them
1575 but may decrease the performance of the system so this option should
1576 be disabled unless the kernel is intended to be run on 2F01 or 2F02

1914 keeps in the memory allocator. If you need to allocate very large

1919 a value of 11 means that the largest free memory block is 2^10 pages.

2432 kexec is a system call that implements the ability to shutdown your

2489 When this is enabled, the kernel will support use of 64-bit floating
2490 point registers with binaries using the O32 ABI along with the
2491 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2492 32-bit MIPS systems this support is at the cost of increasing the
2493 size and complexity of the compiled FPU emulator. Thus if you are
2494 running a MIPS32 system and know that none of your userland binaries
2495 will require 64-bit floating point, you may wish to reduce the size
2496 of your kernel & potentially improve FP emulation performance by
2497 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002499 Although binutils currently supports use of this flag the details
2500 concerning its effect upon the O32 ABI in userland are still being
2501 worked on. In order to avoid userland becoming dependant upon current
2502 behaviour before the details have been finalised, this option should
2503 be considered experimental and only enabled by those working upon
2504 said details.
