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.

2300 SmartMIPS is a extension of the MIPS32 architecture aimed at
2301 increased security at both hardware and software level for
2302 smartcards. Enabling this option will allow proper use of the
2303 SmartMIPS instructions by Linux applications. However a kernel with
2304 this option will not work on a MIPS core without SmartMIPS core. If

2616 kexec is a system call that implements the ability to shutdown your
2617 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002618 but it is independent of the system firmware. And like a reboot

2673 When this is enabled, the kernel will support use of 64-bit floating
2674 point registers with binaries using the O32 ABI along with the
2675 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2676 32-bit MIPS systems this support is at the cost of increasing the
2677 size and complexity of the compiled FPU emulator. Thus if you are
2678 running a MIPS32 system and know that none of your userland binaries
2679 will require 64-bit floating point, you may wish to reduce the size
2680 of your kernel & potentially improve FP emulation performance by
2681 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002683 Although binutils currently supports use of this flag the details
2684 concerning its effect upon the O32 ABI in userland are still being
2685 worked on. In order to avoid userland becoming dependant upon current
2686 behaviour before the details have been finalised, this option should
2687 be considered experimental and only enabled by those working upon
2688 said details.
