1449 Please make sure to pick the right CPU type. Linux/MIPS is not
1450 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1451 *not* work on R4000 machines and vice versa. However, since most
1452 of the supported machines have an R4000 (or similar) CPU, R4x00
1453 might be a safe bet. If the resulting kernel does not work,
1454 try to recompile with R3000.

1682 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1683 benefit is to increase physical addressing equal to or greater
1684 than 40 bits. Note that this has the side effect of turning on
1685 64-bit addressing which in turn makes the PTEs 64-bit in size.

1701 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1702 require workarounds. Without workarounds the system may hang
1703 unexpectedly. For more information please refer to the gas
1704 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1705
1706 Loongson 2F03 and later have fixed these issues and no workarounds
1707 are needed. The workarounds have no significant side effect on them
1708 but may decrease the performance of the system so this option should
1709 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1710 systems.

2299 increased security at both hardware and software level for
2300 smartcards. Enabling this option will allow proper use of the
2301 SmartMIPS instructions by Linux applications. However a kernel with
2302 this option will not work on a MIPS core without SmartMIPS core. If

2614 kexec is a system call that implements the ability to shutdown your
2615 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002616 but it is independent of the system firmware. And like a reboot

2671 When this is enabled, the kernel will support use of 64-bit floating
2672 point registers with binaries using the O32 ABI along with the
2673 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2674 32-bit MIPS systems this support is at the cost of increasing the
2675 size and complexity of the compiled FPU emulator. Thus if you are
2676 running a MIPS32 system and know that none of your userland binaries
2677 will require 64-bit floating point, you may wish to reduce the size
2678 of your kernel & potentially improve FP emulation performance by
2679 saying N here.

Paul Burton06e2e882014-02-14 17:55:18 +00002681 Although binutils currently supports use of this flag the details
2682 concerning its effect upon the O32 ABI in userland are still being
2683 worked on. In order to avoid userland becoming dependant upon current
2684 behaviour before the details have been finalised, this option should
2685 be considered experimental and only enabled by those working upon
2686 said details.
