1452 Please make sure to pick the right CPU type. Linux/MIPS is not
1453 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1454 *not* work on R4000 machines and vice versa. However, since most
1455 of the supported machines have an R4000 (or similar) CPU, R4x00
1456 might be a safe bet. If the resulting kernel does not work,
1457 try to recompile with R3000.

1685 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1686 benefit is to increase physical addressing equal to or greater
1687 than 40 bits. Note that this has the side effect of turning on
1688 64-bit addressing which in turn makes the PTEs 64-bit in size.

1704 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1705 require workarounds. Without workarounds the system may hang
1706 unexpectedly. For more information please refer to the gas
1707 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1708
1709 Loongson 2F03 and later have fixed these issues and no workarounds
1710 are needed. The workarounds have no significant side effect on them
1711 but may decrease the performance of the system so this option should
1712 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1713 systems.

2302 increased security at both hardware and software level for
2303 smartcards. Enabling this option will allow proper use of the
2304 SmartMIPS instructions by Linux applications. However a kernel with
2305 this option will not work on a MIPS core without SmartMIPS core. If

2617 kexec is a system call that implements the ability to shutdown your
2618 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002619 but it is independent of the system firmware. And like a reboot

2674 When this is enabled, the kernel will support use of 64-bit floating
2675 point registers with binaries using the O32 ABI along with the
2676 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2677 32-bit MIPS systems this support is at the cost of increasing the
2678 size and complexity of the compiled FPU emulator. Thus if you are
2679 running a MIPS32 system and know that none of your userland binaries
2680 will require 64-bit floating point, you may wish to reduce the size
2681 of your kernel & potentially improve FP emulation performance by
2682 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002684 Although binutils currently supports use of this flag the details
2685 concerning its effect upon the O32 ABI in userland are still being
2686 worked on. In order to avoid userland becoming dependant upon current
2687 behaviour before the details have been finalised, this option should
2688 be considered experimental and only enabled by those working upon
2689 said details.
