115 | help | |
116 | This kernel feature is useful for number crunching applications | |

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

a116f6d5 | 161 | help |
2f2f371f MS |
162 | The address space of Microblaze processors is only 4 Gigabytes large |
163 | and it has to accommodate user address space, kernel address | |
164 | space as well as some memory mapped IO. That means that, if you | |
165 | have a large amount of physical memory and/or IO, not all of the | |
166 | memory can be "permanently mapped" by the kernel. The physical | |
167 | memory that is not permanently mapped is called "high memory". | |

175 | This option allows you to set the maximum amount of memory which | |
176 | will be used as "low memory", that is, memory which the kernel can | |

233 | Select the kernel logical page size. Increasing the page size | |
234 | will reduce software overhead at each page boundary, allow | |
235 | hardware prefetch mechanisms to be more effective, and allow | |
236 | larger dma transfers increasing IO efficiency and reducing | |
237 | overhead. However the utilization of memory will increase. | |
238 | For example, each cached file will using a multiple of the | |
239 | page size to hold its contents and the difference between the | |
