1311 Please make sure to pick the right CPU type. Linux/MIPS is not
1312 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1313 *not* work on R4000 machines and vice versa. However, since most
1314 of the supported machines have an R4000 (or similar) CPU, R4x00
1315 might be a safe bet. If the resulting kernel does not work,
1316 try to recompile with R3000.

1534 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1535 require workarounds. Without workarounds the system may hang
1536 unexpectedly. For more information please refer to the gas
1537 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1538
1539 Loongson 2F03 and later have fixed these issues and no workarounds
1540 are needed. The workarounds have no significant side effect on them
1541 but may decrease the performance of the system so this option should
1542 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1543 systems.

2446 This kernel feature is useful for number crunching applications
2447 that may need to compute untrusted bytecode during their
2448 execution. By using pipes or other transports made available to
2449 the process as file descriptors supporting the read/write
2450 syscalls, it's possible to isolate those applications in
2451 their own address space using seccomp. Once seccomp is
2452 enabled via /proc/<pid>/seccomp, it cannot be disabled
2453 and the task is only allowed to execute a few safe syscalls

2462 When this is enabled, the kernel will support use of 64-bit floating
2463 point registers with binaries using the O32 ABI along with the
2464 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2465 32-bit MIPS systems this support is at the cost of increasing the
2466 size and complexity of the compiled FPU emulator. Thus if you are
2467 running a MIPS32 system and know that none of your userland binaries
2468 will require 64-bit floating point, you may wish to reduce the size
2469 of your kernel & potentially improve FP emulation performance by
2470 saying N here.
2471
Paul Burton06e2e882014-02-14 17:55:18 +00002472 Although binutils currently supports use of this flag the details
2473 concerning its effect upon the O32 ABI in userland are still being
2474 worked on. In order to avoid userland becoming dependant upon current
2475 behaviour before the details have been finalised, this option should
2476 be considered experimental and only enabled by those working upon
2477 said details.
