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.

1545 If unsure, please say Y.

2420 Generate crash dump after being started by kexec.
2421 This should be normally only set in special crash dump kernels
2422 which are loaded in the main kernel with kexec-tools into
2423 a specially reserved region and then later executed after
2424 a crash by kdump/kexec. The crash dump kernel must be compiled
2425 to a memory address not used by the main kernel or firmware using
2426 PHYSICAL_START.

2445 This kernel feature is useful for number crunching applications
2446 that may need to compute untrusted bytecode during their
2447 execution. By using pipes or other transports made available to
2448 the process as file descriptors supporting the read/write
2449 syscalls, it's possible to isolate those applications in
2450 their own address space using seccomp. Once seccomp is
2451 enabled via /proc/<pid>/seccomp, it cannot be disabled
2452 and the task is only allowed to execute a few safe syscalls
2453 defined by each seccomp mode.

2461 When this is enabled, the kernel will support use of 64-bit floating
2462 point registers with binaries using the O32 ABI along with the
2463 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2464 32-bit MIPS systems this support is at the cost of increasing the
2465 size and complexity of the compiled FPU emulator. Thus if you are
2466 running a MIPS32 system and know that none of your userland binaries
2467 will require 64-bit floating point, you may wish to reduce the size
2468 of your kernel & potentially improve FP emulation performance by
2469 saying N here.
2470
Paul Burton06e2e882014-02-14 17:55:18 +00002471 Although binutils currently supports use of this flag the details
2472 concerning its effect upon the O32 ABI in userland are still being
2473 worked on. In order to avoid userland becoming dependant upon current
2474 behaviour before the details have been finalised, this option should
2475 be considered experimental and only enabled by those working upon
2476 said details.
2477
2478 If unsure, say N.
