1309 Please make sure to pick the right CPU type. Linux/MIPS is not
1310 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1311 *not* work on R4000 machines and vice versa. However, since most
1312 of the supported machines have an R4000 (or similar) CPU, R4x00
1313 might be a safe bet. If the resulting kernel does not work,
1314 try to recompile with R3000.

1532 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which

1534 unexpectedly. For more information please refer to the gas
1535 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1536
1537 Loongson 2F03 and later have fixed these issues and no workarounds
1538 are needed. The workarounds have no significant side effect on them
1539 but may decrease the performance of the system so this option should
1540 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1541 systems.

2419 a specially reserved region and then later executed after
2420 a crash by kdump/kexec. The crash dump kernel must be compiled
2421 to a memory address not used by the main kernel or firmware using

2441 This kernel feature is useful for number crunching applications
2442 that may need to compute untrusted bytecode during their
2443 execution. By using pipes or other transports made available to
2444 the process as file descriptors supporting the read/write
2445 syscalls, it's possible to isolate those applications in
2446 their own address space using seccomp. Once seccomp is
2447 enabled via /proc/<pid>/seccomp, it cannot be disabled
2448 and the task is only allowed to execute a few safe syscalls
2449 defined by each seccomp mode.

2457 When this is enabled, the kernel will support use of 64-bit floating
2458 point registers with binaries using the O32 ABI along with the
2459 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2460 32-bit MIPS systems this support is at the cost of increasing the
2461 size and complexity of the compiled FPU emulator. Thus if you are
2462 running a MIPS32 system and know that none of your userland binaries
2463 will require 64-bit floating point, you may wish to reduce the size
2464 of your kernel & potentially improve FP emulation performance by
2465 saying N here.
2466
Paul Burton06e2e882014-02-14 17:55:18 +00002467 Although binutils currently supports use of this flag the details
2468 concerning its effect upon the O32 ABI in userland are still being
2469 worked on. In order to avoid userland becoming dependant upon current
2470 behaviour before the details have been finalised, this option should
2471 be considered experimental and only enabled by those working upon
2472 said details.
2473
2474 If unsure, say N.
