  1584. This kernel feature is useful for number crunching applications
  1585. that may need to compute untrusted bytecode during their
  1586. execution. By using pipes or other transports made available to
  1587. the process as file descriptors supporting the read/write
  1588. syscalls, it's possible to isolate those applications in
  1589. their own address space using seccomp. Once seccomp is
  1590. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1591. and the task is only allowed to execute a few safe syscalls
  1592. defined by each seccomp mode.

  1601. APM is a BIOS specification for saving power using several different
  1602. techniques. This is mostly useful for battery powered systems with
  1603. APM compliant BIOSes. If you say Y here, the system time will be
  1604. reset after a RESUME operation, the /proc/apm device will provide
  1605. battery status information, and user-space programs will receive
  1606. notification of APM "events" (e.g. battery status change).
  1607. In order to use APM, you will need supporting software. For location
  1608. and more information, read <file:Documentation/pm.txt> and the
  1609. Battery Powered Linux mini-HOWTO, available from
  1610. <http://www.tldp.org/docs.html#howto>.
  1611. This driver does not spin down disk drives (see the hdparm(8)
  1612. manpage ("man 8 hdparm") for that), and it doesn't turn off
  1613. VESA-compliant "green" monitors.
  1614. Generally, if you don't have a battery in your machine, there isn't
  1615. much point in using this driver and you should say N. If you get
  1616. random kernel OOPSes or reboots that don't seem to be related to
  1617. anything, try disabling/enabling this option (or disabling/enabling
  1618. APM in your BIOS).
