1438 Please make sure to pick the right CPU type. Linux/MIPS is not
1439 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1440 *not* work on R4000 machines and vice versa. However, since most
1441 of the supported machines have an R4000 (or similar) CPU, R4x00
1442 might be a safe bet. If the resulting kernel does not work,
1443 try to recompile with R3000.

1671 benefit is to increase physical addressing equal to or greater

1673 64-bit addressing which in turn makes the PTEs 64-bit in size.

1689 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1690 require workarounds. Without workarounds the system may hang
1691 unexpectedly. For more information please refer to the gas
1692 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1693
1694 Loongson 2F03 and later have fixed these issues and no workarounds
1695 are needed. The workarounds have no significant side effect on them
1696 but may decrease the performance of the system so this option should
1697 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1698 systems.

2053 keeps in the memory allocator. If you need to allocate very large

2058 a value of 11 means that the largest free memory block is 2^10 pages.

2290 SmartMIPS is a extension of the MIPS32 architecture aimed at
2291 increased security at both hardware and software level for
2292 smartcards. Enabling this option will allow proper use of the
2293 SmartMIPS instructions by Linux applications. However a kernel with
2294 this option will not work on a MIPS core without SmartMIPS core. If
2295 you don't know you probably don't have SmartMIPS and should say N
2296 here.

2637 execution. By using pipes or other transports made available to
2638 the process as file descriptors supporting the read/write
2639 syscalls, it's possible to isolate those applications in
2640 their own address space using seccomp. Once seccomp is
2641 enabled via /proc/<pid>/seccomp, it cannot be disabled
2642 and the task is only allowed to execute a few safe syscalls

2651 When this is enabled, the kernel will support use of 64-bit floating
2652 point registers with binaries using the O32 ABI along with the
2653 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2654 32-bit MIPS systems this support is at the cost of increasing the
2655 size and complexity of the compiled FPU emulator. Thus if you are
2656 running a MIPS32 system and know that none of your userland binaries
2657 will require 64-bit floating point, you may wish to reduce the size
2658 of your kernel & potentially improve FP emulation performance by
2659 saying N here.
2660
Paul Burton06e2e882014-02-14 17:55:18 +00002661 Although binutils currently supports use of this flag the details
2662 concerning its effect upon the O32 ABI in userland are still being
2663 worked on. In order to avoid userland becoming dependant upon current
2664 behaviour before the details have been finalised, this option should
2665 be considered experimental and only enabled by those working upon
2666 said details.
2667
2668 If unsure, say N.
