1450 Please make sure to pick the right CPU type. Linux/MIPS is not
1451 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1452 *not* work on R4000 machines and vice versa. However, since most
1453 of the supported machines have an R4000 (or similar) CPU, R4x00
1454 might be a safe bet. If the resulting kernel does not work,
1455 try to recompile with R3000.

1683 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1684 benefit is to increase physical addressing equal to or greater
1685 than 40 bits. Note that this has the side effect of turning on
1686 64-bit addressing which in turn makes the PTEs 64-bit in size.

1702 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1703 require workarounds. Without workarounds the system may hang
1704 unexpectedly. For more information please refer to the gas
1705 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1706
1707 Loongson 2F03 and later have fixed these issues and no workarounds
1708 are needed. The workarounds have no significant side effect on them
1709 but may decrease the performance of the system so this option should
1710 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1711 systems.

2644 This kernel feature is useful for number crunching applications
2645 that may need to compute untrusted bytecode during their
2646 execution. By using pipes or other transports made available to
2647 the process as file descriptors supporting the read/write
2648 syscalls, it's possible to isolate those applications in
2649 their own address space using seccomp. Once seccomp is

2660 When this is enabled, the kernel will support use of 64-bit floating
2661 point registers with binaries using the O32 ABI along with the
2662 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2663 32-bit MIPS systems this support is at the cost of increasing the
2664 size and complexity of the compiled FPU emulator. Thus if you are
2665 running a MIPS32 system and know that none of your userland binaries
2666 will require 64-bit floating point, you may wish to reduce the size
2667 of your kernel & potentially improve FP emulation performance by
2668 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002670 Although binutils currently supports use of this flag the details
2671 concerning its effect upon the O32 ABI in userland are still being
2672 worked on. In order to avoid userland becoming dependant upon current
2673 behaviour before the details have been finalised, this option should
2674 be considered experimental and only enabled by those working upon
2675 said details.
