1654 | This is a kernel model which is known a VSMP but lately has been |
1655 | marketesed into SMVP. | |
1656 | Virtual SMP uses the processor's VPEs to implement virtual | |
1657 | processors. In currently available configuration of the 34K processor | |
1658 | this allows for a dual processor. Both processors will share the same | |
1659 | primary caches; each will obtain the half of the TLB for it's own | |
1660 | exclusive use. For a layman this model can be described as similar to | |
1661 | what Intel calls Hyperthreading. | |

2100 | help | |
2101 | kexec is a system call that implements the ability to shutdown your | |
2102 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 2103 | but it is independent of the system firmware. And like a reboot |

2119 | This kernel feature is useful for number crunching applications | |

2121 | execution. By using pipes or other transports made available to | |
2122 | the process as file descriptors supporting the read/write | |
2123 | syscalls, it's possible to isolate those applications in | |
2124 | their own address space using seccomp. Once seccomp is | |
2125 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
2126 | and the task is only allowed to execute a few safe syscalls | |
