1306 Please make sure to pick the right CPU type. Linux/MIPS is not
1307 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1308 *not* work on R4000 machines and vice versa. However, since most
1309 of the supported machines have an R4000 (or similar) CPU, R4x00
1310 might be a safe bet. If the resulting kernel does not work,
1311 try to recompile with R3000.

1529 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1530 require workarounds. Without workarounds the system may hang
1531 unexpectedly. For more information please refer to the gas
1532 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1533
1534 Loongson 2F03 and later have fixed these issues and no workarounds
1535 are needed. The workarounds have no significant side effect on them
1536 but may decrease the performance of the system so this option should
1537 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1538 systems.

2436 help
2437 This kernel feature is useful for number crunching applications
2438 that may need to compute untrusted bytecode during their
2439 execution. By using pipes or other transports made available to
2440 the process as file descriptors supporting the read/write
2441 syscalls, it's possible to isolate those applications in
2442 their own address space using seccomp. Once seccomp is
2443 enabled via /proc/<pid>/seccomp, it cannot be disabled
2444 and the task is only allowed to execute a few safe syscalls
2445 defined by each seccomp mode.
2446
2447 If unsure, say Y. Only embedded should say N here.

2453 When this is enabled, the kernel will support use of 64-bit floating
2454 point registers with binaries using the O32 ABI along with the
2455 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2456 32-bit MIPS systems this support is at the cost of increasing the
2457 size and complexity of the compiled FPU emulator. Thus if you are
2458 running a MIPS32 system and know that none of your userland binaries
2459 will require 64-bit floating point, you may wish to reduce the size
2460 of your kernel & potentially improve FP emulation performance by
2461 saying N here.
2462
Paul Burton06e2e882014-02-14 17:55:18 +00002463 Although binutils currently supports use of this flag the details
2464 concerning its effect upon the O32 ABI in userland are still being
2465 worked on. In order to avoid userland becoming dependant upon current
2466 behaviour before the details have been finalised, this option should
2467 be considered experimental and only enabled by those working upon
2468 said details.
2469
2470 If unsure, say N.
