     28      0    stevel  * This module performs two functions.  First, it kicks off the driver loading
     29      0    stevel  * of the console devices during boot in dynamic_console_config().
     30      0    stevel  * The loading of the drivers for the console devices triggers the
     31      0    stevel  * additional device autoconfiguration to link the drivers into the keyboard
     32      0    stevel  * and mouse console streams.
     33      0    stevel  *
     34      0    stevel  * The second function of this module is to provide the dacf functions
     35      0    stevel  * to be called after a driver has attached and before it detaches.  For
     36      0    stevel  * example, a driver associated with the keyboard will have kb_config called
     37      0    stevel  * after the driver attaches and kb_unconfig before it detaches.  Similar
     38      0    stevel  * configuration actions are performed on behalf of minor nodes representing
     39      0    stevel  * mice.  The configuration functions for the attach case take a module
     40      0    stevel  * name as a parameter.  The module is pushed on top of the driver during
     41      0    stevel  * the configuration.
     42      0    stevel  *
     43      0    stevel  * Although the dacf framework is used to configure all keyboards and mice,
     44      0    stevel  * its primary function is to allow keyboard and mouse hotplugging.
     45      0    stevel  *
     46      0    stevel  * This module supports multiple keyboards and mice at the same time.
     47      0    stevel  *
     48      0    stevel  * From the kernel perspective, there are roughly three different possible
     49      0    stevel  * console configurations.  Across these three configurations, the following
     50      0    stevel  * elements are constant:
     51      0    stevel  * 	wsconsvp = IWSCN_PATH
     52      0    stevel  * 	rwsconsvp = WC_PATH
     53      0    stevel  * 	consms -> msdev
     54      0    stevel  *
     55      0    stevel  * The "->" syntax indicates that the streams device on the right is
     56      0    stevel  * linked under the streams device on the left.
     57      0    stevel  *
     58      0    stevel  * The following lists how the system is configured for different setups:
     59      0    stevel  *
     60      0    stevel  * stdin is a local keyboard.  use stdin and stdout as the console.
     61      0    stevel  * 	sp->cons_input_type = CONSOLE_LOCAL
     62      0    stevel  *	rconsvp = IWSCN_PATH
     63      0    stevel  *	wc -> conskbd -> kbddev
     64      0    stevel  *
     65      0    stevel  * stdin is not a keyboard and stdin is the same as stdout.
     66      0    stevel  * assume we running on a tip line and use stdin/stdout as the console.
     67      0    stevel  * 	sp->cons_input_type = CONSOLE_TIP
     68      0    stevel  *	rconsvp = (stdindev/stdoutdev)
     69      0    stevel  *	wc -> conskbd -> kbddev
     70      0    stevel  *
     71      0    stevel  * stdin is not a keyboard device and it's not the same as stdout.
     72      0    stevel  * assume we have a serial keyboard hooked up and use it along with
     73      0    stevel  * stdout as the console.
     74      0    stevel  * 	sp->cons_input_type = CONSOLE_SERIAL_KEYBOARD
     75      0    stevel  *	rconsvp = IWSCN_PATH
     76      0    stevel  *	wc -> stdindev
     77      0    stevel  *	conskbd -> kbddev
     78      0    stevel  *
     79      0    stevel  * CAVEAT:
     80      0    stevel  * 	The above is all true except for one possible Intel configuration.
     81      0    stevel  * 	If stdin is set to a local keyboard but stdout is set to something
     82      0    stevel  * 	other than the local display (a tip port for example) stdout will
     83      0    stevel  * 	still go to the local display.  This is an artifact of the console
     84      0    stevel  * 	implementation on intel.

    179      0    stevel  * Unfortunatly the sparc variables were well documented.
    180      0    stevel  * So to aviod breaking either sparc or intel we'll declare the variables
