1307 Please make sure to pick the right CPU type. Linux/MIPS is not
1308 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1309 *not* work on R4000 machines and vice versa. However, since most
1310 of the supported machines have an R4000 (or similar) CPU, R4x00
1311 might be a safe bet. If the resulting kernel does not work,
1312 try to recompile with R3000.

1532 unexpectedly. For more information please refer to the gas
1533 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1534
1535 Loongson 2F03 and later have fixed these issues and no workarounds
1536 are needed. The workarounds have no significant side effect on them
1537 but may decrease the performance of the system so this option should
1538 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1539 systems.

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

2454 When this is enabled, the kernel will support use of 64-bit floating
2455 point registers with binaries using the O32 ABI along with the
2456 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2457 32-bit MIPS systems this support is at the cost of increasing the
2458 size and complexity of the compiled FPU emulator. Thus if you are
2459 running a MIPS32 system and know that none of your userland binaries
2460 will require 64-bit floating point, you may wish to reduce the size
2461 of your kernel & potentially improve FP emulation performance by
2462 saying N here.
2463
Paul Burton06e2e882014-02-14 17:55:18 +00002464 Although binutils currently supports use of this flag the details
2465 concerning its effect upon the O32 ABI in userland are still being
2466 worked on. In order to avoid userland becoming dependant upon current
2467 behaviour before the details have been finalised, this option should
2468 be considered experimental and only enabled by those working upon
2469 said details.
2470
2471 If unsure, say N.
