1451 Please make sure to pick the right CPU type. Linux/MIPS is not
1452 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1453 *not* work on R4000 machines and vice versa. However, since most
1454 of the supported machines have an R4000 (or similar) CPU, R4x00
1455 might be a safe bet. If the resulting kernel does not work,
1456 try to recompile with R3000.

1684 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1685 benefit is to increase physical addressing equal to or greater
1686 than 40 bits. Note that this has the side effect of turning on
1687 64-bit addressing which in turn makes the PTEs 64-bit in size.

1703 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1704 require workarounds. Without workarounds the system may hang
1705 unexpectedly. For more information please refer to the gas
1706 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1707
1708 Loongson 2F03 and later have fixed these issues and no workarounds
1709 are needed. The workarounds have no significant side effect on them
1710 but may decrease the performance of the system so this option should
1711 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1712 systems.

2301 increased security at both hardware and software level for
2302 smartcards. Enabling this option will allow proper use of the

2645 This kernel feature is useful for number crunching applications
2646 that may need to compute untrusted bytecode during their
2647 execution. By using pipes or other transports made available to
2648 the process as file descriptors supporting the read/write
2649 syscalls, it's possible to isolate those applications in
2650 their own address space using seccomp. Once seccomp is

2661 When this is enabled, the kernel will support use of 64-bit floating
2662 point registers with binaries using the O32 ABI along with the
2663 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2664 32-bit MIPS systems this support is at the cost of increasing the
2665 size and complexity of the compiled FPU emulator. Thus if you are
2666 running a MIPS32 system and know that none of your userland binaries
2667 will require 64-bit floating point, you may wish to reduce the size
2668 of your kernel & potentially improve FP emulation performance by
2669 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002671 Although binutils currently supports use of this flag the details
2672 concerning its effect upon the O32 ABI in userland are still being
2673 worked on. In order to avoid userland becoming dependant upon current
2674 behaviour before the details have been finalised, this option should
2675 be considered experimental and only enabled by those working upon
2676 said details.
