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

1379 Please make sure to pick the right CPU type. Linux/MIPS is not
1380 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1381 *not* work on R4000 machines and vice versa. However, since most
1382 of the supported machines have an R4000 (or similar) CPU, R4x00
1383 might be a safe bet. If the resulting kernel does not work,

1607 Loongson 2F03 and later have fixed these issues and no workarounds
1608 are needed. The workarounds have no significant side effect on them
1609 but may decrease the performance of the system so this option should

1958 keeps in the memory allocator. If you need to allocate very large

1960 increase this value.

1962 This config option is actually maximum order plus one. For example,
1963 a value of 11 means that the largest free memory block is 2^10 pages.

2541 point registers with binaries using the O32 ABI along with the
2542 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2543 32-bit MIPS systems this support is at the cost of increasing the
2544 size and complexity of the compiled FPU emulator. Thus if you are
2545 running a MIPS32 system and know that none of your userland binaries

2547 of your kernel & potentially improve FP emulation performance by
