1788 bool "Enable seccomp to safely compute untrusted bytecode"
1789 depends on PROC_FS && BROKEN
1792 This kernel feature is useful for number crunching applications
1793 that may need to compute untrusted bytecode during their
1794 execution. By using pipes or other transports made available to
1795 the process as file descriptors supporting the read/write
1796 syscalls, it's possible to isolate those applications in
1797 their own address space using seccomp. Once seccomp is
1798 enabled via /proc/<pid>/seccomp, it cannot be disabled
1799 and the task is only allowed to execute a few safe syscalls
1800 defined by each seccomp mode.
1802 If unsure, say Y. Only embedded should say N here.
1805 bool "Power Management support (EXPERIMENTAL)"
1806 depends on EXPERIMENTAL && SOC_AU1X00
