  1564. This kernel feature is useful for number crunching applications
  1565. that may need to compute untrusted bytecode during their
  1566. execution. By using pipes or other transports made available to
  1567. the process as file descriptors supporting the read/write
  1568. syscalls, it's possible to isolate those applications in
  1569. their own address space using seccomp. Once seccomp is
  1570. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1571. and the task is only allowed to execute a few safe syscalls
  1572. defined by each seccomp mode.
  1573. If unsure, say Y. Only embedded should say N here.

  1581. APM is a BIOS specification for saving power using several different
  1582. techniques. This is mostly useful for battery powered systems with
  1583. APM compliant BIOSes. If you say Y here, the system time will be
  1584. reset after a RESUME operation, the /proc/apm device will provide
  1585. battery status information, and user-space programs will receive
  1586. notification of APM "events" (e.g. battery status change).
  1587. In order to use APM, you will need supporting software. For location
  1588. and more information, read <file:Documentation/pm.txt> and the
  1589. Battery Powered Linux mini-HOWTO, available from
  1590. <http://www.tldp.org/docs.html#howto>.
  1591. This driver does not spin down disk drives (see the hdparm(8)
  1592. manpage ("man 8 hdparm") for that), and it doesn't turn off
  1593. VESA-compliant "green" monitors.
  1594. Generally, if you don't have a battery in your machine, there isn't
  1595. much point in using this driver and you should say N. If you get
  1596. random kernel OOPSes or reboots that don't seem to be related to
  1597. anything, try disabling/enabling this option (or disabling/enabling
  1598. APM in your BIOS).
