| New Loongson 3 CPU (since Loongson-3A R2, as opposed to Loongson-3A | |
| R1, Loongson-3B R1 and Loongson-3B R2) has many enhancements, such as | |
| FTLB, L1-VCache, EI/DI/Wait/Prefetch instruction, DSP/DSPv2 ASE, User | |
| Local register, Read-Inhibit/Execute-Inhibit, SFB (Store Fill Buffer), | |

| help | |
| kexec is a system call that implements the ability to shutdown your | |
| current kernel, and to start another kernel. It is like a reboot | |
| but it is independent of the system firmware. And like a reboot | |
| you can start any kernel with it, not just Linux. | |
| The name comes from the similarity to the exec system call. | |
| It is an ongoing process to be certain the hardware in a machine | |
| is properly shutdown, so do not be surprised if this code does not | |
| initially work for you. As of this writing the exact hardware | |
| interface is strongly in flux, so no good recommendation can be | |

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

| config MIPS_O32_FP64_SUPPORT | |

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