  1583. This kernel feature is useful for number crunching applications
  1584. that may need to compute untrusted bytecode during their
  1585. execution. By using pipes or other transports made available to
  1586. the process as file descriptors supporting the read/write
  1587. syscalls, it's possible to isolate those applications in
  1588. their own address space using seccomp. Once seccomp is
  1589. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1590. and the task is only allowed to execute a few safe syscalls
  1591. defined by each seccomp mode.

  1600. APM is a BIOS specification for saving power using several different
  1601. techniques. This is mostly useful for battery powered systems with
  1602. APM compliant BIOSes. If you say Y here, the system time will be
  1603. reset after a RESUME operation, the /proc/apm device will provide
  1604. battery status information, and user-space programs will receive
  1605. notification of APM "events" (e.g. battery status change).
  1606. In order to use APM, you will need supporting software. For location
  1607. and more information, read <file:Documentation/pm.txt> and the
  1608. Battery Powered Linux mini-HOWTO, available from
  1609. <http://www.tldp.org/docs.html#howto>.
  1610. This driver does not spin down disk drives (see the hdparm(8)
  1611. manpage ("man 8 hdparm") for that), and it doesn't turn off
  1612. VESA-compliant "green" monitors.
  1613. Generally, if you don't have a battery in your machine, there isn't
  1614. much point in using this driver and you should say N. If you get
  1615. random kernel OOPSes or reboots that don't seem to be related to
  1616. anything, try disabling/enabling this option (or disabling/enabling
  1617. APM in your BIOS).
