1442 Please make sure to pick the right CPU type. Linux/MIPS is not
1443 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1444 *not* work on R4000 machines and vice versa. However, since most
1445 of the supported machines have an R4000 (or similar) CPU, R4x00
1446 might be a safe bet. If the resulting kernel does not work,
1447 try to recompile with R3000.

1674 Choose this option if you want to enable the Extended Physical
1675 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1676 benefit is to increase physical addressing equal to or greater
1677 than 40 bits. Note that this has the side effect of turning on
1678 64-bit addressing which in turn makes the PTEs 64-bit in size.

1694 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1695 require workarounds. Without workarounds the system may hang
1696 unexpectedly. For more information please refer to the gas
1697 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1698
1699 Loongson 2F03 and later have fixed these issues and no workarounds
1700 are needed. The workarounds have no significant side effect on them
1701 but may decrease the performance of the system so this option should
1702 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1703 systems.
1704
1705 If unsure, please say Y.

2055 The kernel memory allocator divides physically contiguous memory
2056 blocks into "zones", where each zone is a power of two number of
2057 pages. This option selects the largest power of two that the kernel
2058 keeps in the memory allocator. If you need to allocate very large
2059 blocks of physically contiguous memory, then you may need to
2060 increase this value.
2061
2062 This config option is actually maximum order plus one. For example,
2063 a value of 11 means that the largest free memory block is 2^10 pages.

2295 SmartMIPS is a extension of the MIPS32 architecture aimed at
2296 increased security at both hardware and software level for
2297 smartcards. Enabling this option will allow proper use of the
2298 SmartMIPS instructions by Linux applications. However a kernel with
2299 this option will not work on a MIPS core without SmartMIPS core. If
2300 you don't know you probably don't have SmartMIPS and should say N
2301 here.

2640 This kernel feature is useful for number crunching applications
2641 that may need to compute untrusted bytecode during their
2642 execution. By using pipes or other transports made available to
2643 the process as file descriptors supporting the read/write
2644 syscalls, it's possible to isolate those applications in
2645 their own address space using seccomp. Once seccomp is
2646 enabled via /proc/<pid>/seccomp, it cannot be disabled
2647 and the task is only allowed to execute a few safe syscalls
2648 defined by each seccomp mode.

Paul Burton597ce172013-11-22 13:12:07 +00002655 help
2656 When this is enabled, the kernel will support use of 64-bit floating
2657 point registers with binaries using the O32 ABI along with the
2658 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2659 32-bit MIPS systems this support is at the cost of increasing the
2660 size and complexity of the compiled FPU emulator. Thus if you are
2661 running a MIPS32 system and know that none of your userland binaries
2662 will require 64-bit floating point, you may wish to reduce the size
2663 of your kernel & potentially improve FP emulation performance by
2664 saying N here.
2665
Paul Burton06e2e882014-02-14 17:55:18 +00002666 Although binutils currently supports use of this flag the details
2667 concerning its effect upon the O32 ABI in userland are still being
2668 worked on. In order to avoid userland becoming dependant upon current
2669 behaviour before the details have been finalised, this option should
2670 be considered experimental and only enabled by those working upon
2671 said details.
2672
2673 If unsure, say N.
