1313 Please make sure to pick the right CPU type. Linux/MIPS is not
1314 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1315 *not* work on R4000 machines and vice versa. However, since most
1316 of the supported machines have an R4000 (or similar) CPU, R4x00
1317 might be a safe bet. If the resulting kernel does not work,
1318 try to recompile with R3000.

1538 unexpectedly. For more information please refer to the gas
1539 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1540
1541 Loongson 2F03 and later have fixed these issues and no workarounds
1542 are needed. The workarounds have no significant side effect on them
1543 but may decrease the performance of the system so this option should
1544 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1545 systems.

2407 kexec is a system call that implements the ability to shutdown your
2408 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02002409 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09002410 you can start any kernel with it, not just Linux.

Matt LaPlante01dd2fb2007-10-20 01:34:40 +02002412 The name comes from the similarity to the exec system call.

2448 This kernel feature is useful for number crunching applications
2449 that may need to compute untrusted bytecode during their
2450 execution. By using pipes or other transports made available to
2451 the process as file descriptors supporting the read/write
2452 syscalls, it's possible to isolate those applications in
2453 their own address space using seccomp. Once seccomp is
2454 enabled via /proc/<pid>/seccomp, it cannot be disabled
2455 and the task is only allowed to execute a few safe syscalls

2464 When this is enabled, the kernel will support use of 64-bit floating
2465 point registers with binaries using the O32 ABI along with the
2466 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2467 32-bit MIPS systems this support is at the cost of increasing the
2468 size and complexity of the compiled FPU emulator. Thus if you are
2469 running a MIPS32 system and know that none of your userland binaries
2470 will require 64-bit floating point, you may wish to reduce the size
2471 of your kernel & potentially improve FP emulation performance by
2472 saying N here.
2473
Paul Burton06e2e882014-02-14 17:55:18 +00002474 Although binutils currently supports use of this flag the details
2475 concerning its effect upon the O32 ABI in userland are still being
2476 worked on. In order to avoid userland becoming dependant upon current
2477 behaviour before the details have been finalised, this option should
2478 be considered experimental and only enabled by those working upon
2479 said details.

2481 If unsure, say N.
