| help |
| This kernel feature is useful for number crunching applications |
| that may need to compute untrusted bytecode during their |
| execution. By using pipes or other transports made available to |
| the process as file descriptors supporting the read/write |
| syscalls, it's possible to isolate those applications in |
| their own address space using seccomp. Once seccomp is |
| enabled via /proc/<pid>/seccomp, it cannot be disabled |
| and the task is only allowed to execute a few safe syscalls |
| defined by each seccomp mode. |
| |
| If unsure, say Y. Only embedded should say N here. |

| help |
| Select the kernel logical page size. Increasing the page size |
| will reduce software overhead at each page boundary, allow |
| hardware prefetch mechanisms to be more effective, and allow |
| larger dma transfers increasing IO efficiency and reducing |
| overhead. However the utilization of memory will increase. |
| For example, each cached file will using a multiple of the |
| page size to hold its contents and the difference between the |
| end of file and the end of page is wasted. |
| |
| If unsure, choose 4K_PAGES. |
