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

1384 Please make sure to pick the right CPU type. Linux/MIPS is not
1385 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1961 blocks into "zones", where each zone is a power of two number of
1962 pages. This option selects the largest power of two that the kernel
1963 keeps in the memory allocator. If you need to allocate very large
1964 blocks of physically contiguous memory, then you may need to
1965 increase this value.

1967 This config option is actually maximum order plus one. For example,
1968 a value of 11 means that the largest free memory block is 2^10 pages.

2545 When this is enabled, the kernel will support use of 64-bit floating
2546 point registers with binaries using the O32 ABI along with the
2547 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2548 32-bit MIPS systems this support is at the cost of increasing the
2549 size and complexity of the compiled FPU emulator. Thus if you are
2550 running a MIPS32 system and know that none of your userland binaries
2551 will require 64-bit floating point, you may wish to reduce the size
2552 of your kernel & potentially improve FP emulation performance by
