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. * assume we running on a tip line and use stdin/stdout as the console. * sp->cons_input_type = CONSOLE_TIP * rconsvp = (stdindev/stdoutdev) * 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. */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include /* * External global variables */ extern vnode_t *rconsvp; extern dev_t rwsconsdev; /* * External functions */ extern uintptr_t space_fetch(char *key); extern int space_store(char *key, uintptr_t ptr); /* * Tasks */ static int kb_config(dacf_infohdl_t, dacf_arghdl_t, int); static int kb_unconfig(dacf_infohdl_t, dacf_arghdl_t, int); static int ms_config(dacf_infohdl_t, dacf_arghdl_t, int); static int ms_unconfig(dacf_infohdl_t, dacf_arghdl_t, int); /* * Internal functions */ static int consconfig_setmodes(dev_t dev, struct termios *termiosp); static void consconfig_check_phys_kbd(cons_state_t *); static void consconfig_rem_dev(cons_state_t *, dev_t); static void consconfig_add_dev(cons_state_t *, cons_prop_t *); static cons_prop_t *consconfig_find_dev(cons_state_t *, dev_t); static void consconfig_free_prop(cons_prop_t *prop); static void flush_deferred_console_buf(void); /* * On supported configurations, the firmware defines the keyboard and mouse * paths.
