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.
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.
Return the driver-specific state of dev. The softc is automatically allocated the first time it is requested. The size of the allocation is determined by the device's driver_t information used to def...
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...
