1263 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1264 | *not* work on R4000 machines and vice versa. However, since most | |

2428 | help | |
2429 | This kernel feature is useful for number crunching applications | |
2430 | that may need to compute untrusted bytecode during their | |
2431 | execution. By using pipes or other transports made available to | |
2432 | the process as file descriptors supporting the read/write | |
2433 | syscalls, it's possible to isolate those applications in | |
2434 | their own address space using seccomp. Once seccomp is | |
2435 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2436 | and the task is only allowed to execute a few safe syscalls | |
2437 | defined by each seccomp mode. | |

2448 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2449 | 32-bit MIPS systems this support is at the cost of increasing the | |
2450 | size and complexity of the compiled FPU emulator. Thus if you are | |
2451 | running a MIPS32 system and know that none of your userland binaries | |
2452 | will require 64-bit floating point, you may wish to reduce the size | |
