pm_planar_control Kernel Service

AIX Version 4.3 Kernel and Subsystems Technical Reference, Volume 1

Controls power of a specified device on the planar.

#include <sys/pm.h>
int pm_planar_control(DevNumber,DevID,command)
dev_t DevNumber;
int DevID;
int command;

DevNumber

Specifies the major minor number of the caller device. If caller is not a device, DevNumber is 0.

DevID

Specifies the planar device ID.

command

Specifies one of the following:

PM_PLANAR_QUERY	Queries supported commands of the kernel service.
PM_PLANAR_ON	Turns the device on.
PM_PLANAR_OFF	Turns the device off.
PM_PLANAR_LOWPOWER1	Brings the device into low power 1.
PM_PLANAR_LOWPOWER2	Brings the device into low power 2.

The pm_planar_control kernel service turns a device on the planar either on or off.

If command is PM_PLANAR_QUERY, OR of the following is returned:

PM_PLANAR_ON

PM_PLANAR_OFF

PM_PLANAR_LOWPOWER1

or PM_PLANAR_LOWPOWER2

If command is other than PM_PLANAR_QUERY the following is returned:

PM_SUCCESS	Indicates successful completion.
PM_ERROR	Indicates an error condition.

The pm_planar_control kernel service can be called from either the process or interrupt environment.

The pm_planar_control kernel service is part of the Base Operating System (BOS) Runtime.
