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 | |

2405 | execution. By using pipes or other transports made available to | |
2406 | the process as file descriptors supporting the read/write | |
2407 | syscalls, it's possible to isolate those applications in | |
2408 | their own address space using seccomp. Once seccomp is | |

2420 | When this is enabled, the kernel will support use of 64-bit floating | |
2421 | point registers with binaries using the O32 ABI along with the | |
2422 | EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On | |
2423 | 32-bit MIPS systems this support is at the cost of increasing the | |
2424 | size and complexity of the compiled FPU emulator. Thus if you are | |
2425 | running a MIPS32 system and know that none of your userland binaries | |
2426 | will require 64-bit floating point, you may wish to reduce the size | |
2427 | of your kernel & potentially improve FP emulation performance by | |
2428 | saying N here. | |
