1805 This kernel feature is useful for number crunching applications
1806 that may need to compute untrusted bytecode during their
1807 execution. By using pipes or other transports made available to
1808 the process as file descriptors supporting the read/write
1809 syscalls, it's possible to isolate those applications in
1810 their own address space using seccomp. Once seccomp is
1811 enabled via /proc/<pid>/seccomp, it cannot be disabled
1812 and the task is only allowed to execute a few safe syscalls
1813 defined by each seccomp mode.
1815 If unsure, say Y. Only embedded should say N here.
1818 bool "Power Management support (EXPERIMENTAL)"
1819 depends on EXPERIMENTAL && SOC_AU1X00
