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. | |

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