/*
* This module performs two functions. First, it kicks off the driver loading
* of the console devices during boot in dynamic_console_config().
* The loading of the drivers for the console devices triggers the
* additional device autoconfiguration to link the drivers into the keyboard
* and mouse console streams.
*
* The second function of this module is to provide the dacf functions
* to be called after a driver has attached and before it detaches. For
* example, a driver associated with the keyboard will have kb_config called
* after the driver attaches and kb_unconfig before it detaches. Similar
* configuration actions are performed on behalf of minor nodes representing
* mice. The configuration functions for the attach case take a module
* name as a parameter. The module is pushed on top of the driver during
* the configuration.
*
* Although the dacf framework is used to configure all keyboards and mice,
* its primary function is to allow keyboard and mouse hotplugging.
*
* This module supports multiple keyboards and mice at the same time.
*
* From the kernel perspective, there are roughly three different possible
* console configurations. Across these three configurations, the following
* elements are constant:
* wsconsvp = IWSCN_PATH
* rwsconsvp = WC_PATH
* consms -> msdev
*
* The "->" syntax indicates that the streams device on the right is
* linked under the streams device on the left.
*
* The following lists how the system is configured for different setups:
*
* stdin is a local keyboard. use stdin and stdout as the console.
* sp->cons_input_type = CONSOLE_LOCAL
* rconsvp = IWSCN_PATH
* wc -> conskbd -> kbddev
*
* stdin is not a keyboard and stdin is the same as stdout.
* sp->cons_input_type = CONSOLE_TIP
* wc -> conskbd -> kbddev
*
* stdin is not a keyboard device and it's not the same as stdout.
* assume we have a serial keyboard hooked up and use it along with
* stdout as the console.
* sp->cons_input_type = CONSOLE_SERIAL_KEYBOARD
* rconsvp = IWSCN_PATH
* wc -> stdindev
* conskbd -> kbddev
*
* CAVEAT:
* The above is all true except for one possible Intel configuration.
* If stdin is set to a local keyboard but stdout is set to something
* other than the local display (a tip port for example) stdout will
* still go to the local display. This is an artifact of the console
* implementation on intel.
