sys_attrs_pwrmgr(5)


NAME

  sys_attrs_pwrmgr - pwrmgr subsystem attributes


DESCRIPTION

  This reference page lists and describes attributes for the Power Manager
  (pwrmgr) kernel subsystem. To change these attributes so that they take
  effect each time you boot the system, you create a stanza file with the
  attribute settings you want and then use the sysconfigdb command to update
  the system configuration database with the information in this file. See
  the EXAMPLES section for more information about this process.	 Refer to the
  sys_attrs(5) reference page for an general introduction to the topic of
  kernel subsystem attributes.

  cpu_slowdown
      A value that enables (1) or disables (0) CPU slowdown after the CPU
      becomes idle.

  default_pwrmgr_state
      A value that enables (1) or disables (0) all power management functions
      (for CPU, disks, and graphics hardware).

  disk_dwell_time
      The number of minutes to wait before powering down registered disks
      after they become idle.

  disk_spindown
      A value that enables (1) or disables (0) disk spindown after registered
      disks become idle.

  graphics_off_dwell
      The number of minutes before entering DPMS off mode after display
      hardware has become idle. If you specify 0 for this attribute, DPMS off
      mode is disabled.

  graphics_powerdown
      A value that enables (1) or disables (0) Display Power Management
      Signaling (DPMS) modes for graphics display hardware.

  graphics_standby_dwell
      The number of minutes before entering DPMS standby mode after display
      hardware has become idle. If you specify 0 for this attribute, DPMS
      standby mode is disabled.

  graphics_suspend_dwell
      The number of minutes before entering DPMS suspend mode after display
      hardware has become idle. If you specify 0 for this attribute, DPMS
      suspend mode is disabled.


EXAMPLES

  The following example shows a sample stanza file named power_mgr.stanza:

       pwrmgr:
			 default_pwrmgr_state=1
			 cpu_slowdown=1
			 disk_spindown=1
			 disk_dwell_time=20
			 graphics_powerdown=1
			 graphics_standby_dwell=5
			 graphics_suspend_dwell=10
			 graphics_off_dwell=15

  This file:

    ·  Enables power management in general, plus  all three of the power
       management options for idle hardware (CPU slowdown, disk spindown, and
       DPMS modes for graphics displays)

    ·  Specifies a wait of 20 minutes before spinning down a disk after it
       has become idle

    ·  Specifies a wait of 5, 10, and 15 minutes before entering DPMS
       standby, suspend, and off modes, respectively, after graphics display
       hardware has become idle

  See stanza(4) for more information about stanza files.

  The following command updates the /etc/sysconfigtab database with the
  information in the stanza file:

       # sysconfigdb -a -f power_mgr.stanza pwrmgr

  See sysconfigdb(8) for more information about using this command to update
  the system configuration database.
