1650 | This is a kernel model which is known a VSMP but lately has been |
1651 | marketesed into SMVP. | |
1652 | Virtual SMP uses the processor's VPEs to implement virtual | |
1653 | processors. In currently available configuration of the 34K processor | |
1654 | this allows for a dual processor. Both processors will share the same | |
1655 | primary caches; each will obtain the half of the TLB for it's own | |
1656 | exclusive use. For a layman this model can be described as similar to | |
1657 | what Intel calls Hyperthreading. | |

2096 | help | |
2097 | kexec is a system call that implements the ability to shutdown your | |
2098 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 2099 | but it is independent of the system firmware. And like a reboot |
ea6e942b AN |
2100 | you can start any kernel with it, not just Linux. |

2104 | It is an ongoing process to be certain the hardware in a machine | |
2105 | is properly shutdown, so do not be surprised if this code does not | |
2106 | initially work for you. It may help to enable device hotplugging | |

2115 | This kernel feature is useful for number crunching applications | |
2116 | that may need to compute untrusted bytecode during their | |
2117 | execution. By using pipes or other transports made available to | |
2118 | the process as file descriptors supporting the read/write | |
2119 | syscalls, it's possible to isolate those applications in | |
2120 | their own address space using seccomp. Once seccomp is | |
2121 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2122 | and the task is only allowed to execute a few safe syscalls | |
