1439 Please make sure to pick the right CPU type. Linux/MIPS is not
1440 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1441 *not* work on R4000 machines and vice versa. However, since most
1442 of the supported machines have an R4000 (or similar) CPU, R4x00
1443 might be a safe bet. If the resulting kernel does not work,
1444 try to recompile with R3000.

1672 benefit is to increase physical addressing equal to or greater

1674 64-bit addressing which in turn makes the PTEs 64-bit in size.

1690 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1691 require workarounds. Without workarounds the system may hang
1692 unexpectedly. For more information please refer to the gas
1693 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1694
1695 Loongson 2F03 and later have fixed these issues and no workarounds
1696 are needed. The workarounds have no significant side effect on them
1697 but may decrease the performance of the system so this option should
1698 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1699 systems.

2054 keeps in the memory allocator. If you need to allocate very large

2059 a value of 11 means that the largest free memory block is 2^10 pages.

2291 SmartMIPS is a extension of the MIPS32 architecture aimed at
2292 increased security at both hardware and software level for
2293 smartcards. Enabling this option will allow proper use of the
2294 SmartMIPS instructions by Linux applications. However a kernel with
2295 this option will not work on a MIPS core without SmartMIPS core. If
2296 you don't know you probably don't have SmartMIPS and should say N
2297 here.

2638 execution. By using pipes or other transports made available to
2639 the process as file descriptors supporting the read/write
2640 syscalls, it's possible to isolate those applications in
2641 their own address space using seccomp. Once seccomp is
2642 enabled via /proc/<pid>/seccomp, it cannot be disabled
2643 and the task is only allowed to execute a few safe syscalls

2652 When this is enabled, the kernel will support use of 64-bit floating
2653 point registers with binaries using the O32 ABI along with the
2654 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2655 32-bit MIPS systems this support is at the cost of increasing the
2656 size and complexity of the compiled FPU emulator. Thus if you are
2657 running a MIPS32 system and know that none of your userland binaries
2658 will require 64-bit floating point, you may wish to reduce the size
2659 of your kernel & potentially improve FP emulation performance by
2660 saying N here.
2661
Paul Burton06e2e882014-02-14 17:55:18 +00002662 Although binutils currently supports use of this flag the details
2663 concerning its effect upon the O32 ABI in userland are still being
2664 worked on. In order to avoid userland becoming dependant upon current
2665 behaviour before the details have been finalised, this option should
2666 be considered experimental and only enabled by those working upon
2667 said details.
2668
2669 If unsure, say N.
