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

a116f6d5 | 154 | help |
2f2f371f MS |
155 | The address space of Microblaze processors is only 4 Gigabytes large |
156 | and it has to accommodate user address space, kernel address | |
157 | space as well as some memory mapped IO. That means that, if you | |
158 | have a large amount of physical memory and/or IO, not all of the | |
159 | memory can be "permanently mapped" by the kernel. The physical | |
160 | memory that is not permanently mapped is called "high memory". | |

168 | This option allows you to set the maximum amount of memory which | |
169 | will be used as "low memory", that is, memory which the kernel can | |
170 | access directly, without having to set up a kernel virtual mapping. | |

226 | Select the kernel logical page size. Increasing the page size | |
227 | will reduce software overhead at each page boundary, allow | |
228 | hardware prefetch mechanisms to be more effective, and allow | |
229 | larger dma transfers increasing IO efficiency and reducing | |
230 | overhead. However the utilization of memory will increase. | |
231 | For example, each cached file will using a multiple of the | |
232 | page size to hold its contents and the difference between the | |
