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

a116f6d5 | 160 | help |
2f2f371f MS |
161 | The address space of Microblaze processors is only 4 Gigabytes large |
162 | and it has to accommodate user address space, kernel address | |
163 | space as well as some memory mapped IO. That means that, if you | |
164 | have a large amount of physical memory and/or IO, not all of the | |
165 | memory can be "permanently mapped" by the kernel. The physical | |
166 | memory that is not permanently mapped is called "high memory". | |

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

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