Solaris DDI specific (Solaris DDI).

dip

Pointer to the device's dev_info structure

components

Number of components to create

The pm_create_components() and pm_destroy_components() functions are now obsolete and will be removed in a future release. It is recommended that the driver use pm-components(9) instead.

The pm_create_components() function creates power-manageable components for a device. It should be called from the driver's attach(9E) entry point if the device has power-manageable components.

The correspondence of components to parts of the physical device controlled by the driver are the responsibility of the driver.

The pm_destroy_components() function removes all components from the device. It should be called from the driver's detach(9E) entry point.

The pm_create_components() function returns:

DDI_SUCCESS

Components are successfully created.

DDI_FAILURE

The device already has components.

These functions may be called from user or kernel context.
