1444 Please make sure to pick the right CPU type. Linux/MIPS is not
1445 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1446 *not* work on R4000 machines and vice versa. However, since most
1447 of the supported machines have an R4000 (or similar) CPU, R4x00
1448 might be a safe bet. If the resulting kernel does not work,
1449 try to recompile with R3000.

1677 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1678 benefit is to increase physical addressing equal to or greater
1679 than 40 bits. Note that this has the side effect of turning on
1680 64-bit addressing which in turn makes the PTEs 64-bit in size.

1696 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1697 require workarounds. Without workarounds the system may hang
1698 unexpectedly. For more information please refer to the gas
1699 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1700
1701 Loongson 2F03 and later have fixed these issues and no workarounds
1702 are needed. The workarounds have no significant side effect on them
1703 but may decrease the performance of the system so this option should
1704 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1705 systems.
1706
1707 If unsure, please say Y.

2060 keeps in the memory allocator. If you need to allocate very large

2062 increase this value.

2065 a value of 11 means that the largest free memory block is 2^10 pages.

2297 SmartMIPS is a extension of the MIPS32 architecture aimed at
2298 increased security at both hardware and software level for
2299 smartcards. Enabling this option will allow proper use of the
2300 SmartMIPS instructions by Linux applications. However a kernel with
2301 this option will not work on a MIPS core without SmartMIPS core. If
2302 you don't know you probably don't have SmartMIPS and should say N

2641 help
2642 This kernel feature is useful for number crunching applications
2643 that may need to compute untrusted bytecode during their
2644 execution. By using pipes or other transports made available to
2645 the process as file descriptors supporting the read/write
2646 syscalls, it's possible to isolate those applications in
2647 their own address space using seccomp. Once seccomp is
2648 enabled via /proc/<pid>/seccomp, it cannot be disabled
2649 and the task is only allowed to execute a few safe syscalls
2650 defined by each seccomp mode.

Paul Burton597ce172013-11-22 13:12:07 +00002657 help
2658 When this is enabled, the kernel will support use of 64-bit floating
2659 point registers with binaries using the O32 ABI along with the
2660 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2661 32-bit MIPS systems this support is at the cost of increasing the
2662 size and complexity of the compiled FPU emulator. Thus if you are
2663 running a MIPS32 system and know that none of your userland binaries
2664 will require 64-bit floating point, you may wish to reduce the size
2665 of your kernel & potentially improve FP emulation performance by
2666 saying N here.
2667
Paul Burton06e2e882014-02-14 17:55:18 +00002668 Although binutils currently supports use of this flag the details
2669 concerning its effect upon the O32 ABI in userland are still being
2670 worked on. In order to avoid userland becoming dependant upon current
2671 behaviour before the details have been finalised, this option should
2672 be considered experimental and only enabled by those working upon
2673 said details.
2674
2675 If unsure, say N.
