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

124 | execution. By using pipes or other transports made available to | |
125 | the process as file descriptors supporting the read/write | |
126 | syscalls, it's possible to isolate those applications in | |
127 | their own address space using seccomp. Once seccomp is | |
128 | enabled via /proc/<pid>/seccomp, it cannot be disabled | |
129 | and the task is only allowed to execute a few safe syscalls | |
130 | defined by each seccomp mode. | |

2f2f371f MS |
164 | The address space of Microblaze processors is only 4 Gigabytes large |
165 | and it has to accommodate user address space, kernel address | |
166 | space as well as some memory mapped IO. That means that, if you | |
167 | have a large amount of physical memory and/or IO, not all of the | |
168 | memory can be "permanently mapped" by the kernel. The physical | |
169 | memory that is not permanently mapped is called "high memory". | |

235 | Select the kernel logical page size. Increasing the page size | |

239 | overhead. However the utilization of memory will increase. | |
