931 Say Y here to allow turning CPUs off and on. CPUs can be

933 (Note: power management support will enable this option
934 automatically on SMP systems. )

1264 Please make sure to pick the right CPU type. Linux/MIPS is not
1265 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1266 *not* work on R4000 machines and vice versa. However, since most
1267 of the supported machines have an R4000 (or similar) CPU, R4x00
1268 might be a safe bet. If the resulting kernel does not work,
1269 try to recompile with R3000.

1493 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1494 require workarounds. Without workarounds the system may hang
1495 unexpectedly. For more information please refer to the gas
1496 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1497
1498 Loongson 2F03 and later have fixed these issues and no workarounds
1499 are needed. The workarounds have no significant side effect on them
1500 but may decrease the performance of the system so this option should
1501 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1502 systems.

1826 keeps in the memory allocator. If you need to allocate very large

1828 increase this value.

1830 This config option is actually maximum order plus one. For example,
1831 a value of 11 means that the largest free memory block is 2^10 pages.

2445 bool "Support for O32 binaries using 64-bit FP"
2446 depends on 32BIT || MIPS32_O32
2447 default y
2448 help
2449 When this is enabled, the kernel will support use of 64-bit floating
2450 point registers with binaries using the O32 ABI along with the
2451 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2452 32-bit MIPS systems this support is at the cost of increasing the
2453 size and complexity of the compiled FPU emulator. Thus if you are
2454 running a MIPS32 system and know that none of your userland binaries
2455 will require 64-bit floating point, you may wish to reduce the size
2456 of your kernel & potentially improve FP emulation performance by
2457 saying N here.
2458
2459 If unsure, say Y.

2520 The Extended Industry Standard Architecture (EISA) bus was
2521 developed as an open alternative to the IBM MicroChannel bus.
2522
2523 The EISA bus provided some of the features of the IBM MicroChannel
2524 bus while maintaining backward compatibility with cards made for
2525 the older ISA bus. The EISA bus saw limited use between 1988 and
2526 1995 when it was made obsolete by the PCI bus.
