Create a new child device of dev. The name and unit arguments specify the name and unit number of the device. If the name is unknown then the caller should pass NULL. If the unit is unknown then the c...
Attach a device to the system. The probe method will have been called and will have indicated that the device exists. This routine should initialise the hardware and allocate other system resources (s...
The current state of a device is accessed by calling device_get_state() which returns DS_NOTPRESENT, DS_ALIVE, DS_ATTACHED or DS_BUSY (described in device(9)). To test see if a device was successfully...
The specified device is removed from dev and deleted. If the device is currently attached, it is first detached (see DEVICE_ATTACH(9) and DEVICE_DETACH(9)).
Detach a device. This can be called if the user is replacing the driver software or if a device is about to be physically removed from the system (e.g. for pccard devices). The method should deallocat...
Each device has an enabled flag associated with it. A device is enabled by default when it is created but may be disabled (for instance to prevent a destructive or time consuming probe attempt). To di...

Retrieve a list of all device instances currently connected to dev and return the list in *devlistp and the count in *devcountp. The memory allocated for the list should be freed using free(*devlistp,...
Manipulate the verbose description of a device. This description (if present) is printed as part of the message when it is attached during autoconfiguration. The variation device_set_desc_copy() is us...
Each device supports a set of driver-dependent flags which are often used to control device behaviour. These flags are read by calling device_get_flags() and written by calling device_set_flags().
The device_get_ivars() function returns the bus-specific instance variables of a device. The device_set_ivars() function sets the bus-specific instance variables of a device. Typically, only bus drive...
The device_get_name() function returns the name of the device's device class. The device_get_nameunit() function returns the name of the device's instance.
