First, it kicks off the driver loading 29 * of the console devices during boot in dynamic_console_config(). 30 * The loading of the drivers for the console devices triggers the 31 * additional device autoconfiguration to link the drivers into the keyboard 32 * and mouse console streams. 33 * 34 * The second function of this module is to provide the dacf functions 35 * to be called after a driver has attached and before it detaches. For 36 * example, a driver associated with the keyboard will have kb_config called 37 * after the driver attaches and kb_unconfig before it detaches. Similar 38 * configuration actions are performed on behalf of minor nodes representing 39 * mice. The configuration functions for the attach case take a module 40 * name as a parameter. The module is pushed on top of the driver during 41 * the configuration. 42 * 43 * Although the dacf framework is used to configure all keyboards and mice, 44 * its primary function is to allow keyboard and mouse hotplugging. 45 * 46 * This module supports multiple keyboards and mice at the same time. 47 * 48 * From the kernel perspective, there are roughly three different possible 49 * console configurations. Across these three configurations, the following 50 * elements are constant: 51 * wsconsvp = IWSCN_PATH 52 * rwsconsvp = WC_PATH 53 * consms -> msdev 54 * 55 * The "->" syntax indicates that the streams device on the right is 56 * linked under the streams device on the left. 57 * 58 * The following lists how the system is configured for different setups: 59 * 60 * stdin is a local keyboard. use stdin and stdout as the console. 61 * sp->cons_input_type = CONSOLE_LOCAL 62 * rconsvp = IWSCN_PATH 63 * wc -> conskbd -> kbddev 64 * 65 * stdin is not a keyboard and stdin is the same as stdout. 66 * assume we running on a tip line and use stdin/stdout as the console. 67 * sp->cons_input_type = CONSOLE_TIP 68 * rconsvp = (stdindev/stdoutdev) 69 * wc -> conskbd -> kbddev 70 * 71 * stdin is not a keyboard device and it's not the same as stdout. 72 * assume we have a serial keyboard hooked up and use it along with 73 * stdout as the console. 74 * sp->cons_input_type = CONSOLE_SERIAL_KEYBOARD 75 * rconsvp = IWSCN_PATH 76 * wc -> stdindev 77 * conskbd -> kbddev 78 * 79 * CAVEAT: 80 * The above is all true except for one possible Intel configuration. 81 * If stdin is set to a local keyboard but stdout is set to something 82 * other than the local display (a tip port for example) stdout will 83 * still go to the local display. This is an artifact of the console 84 * implementation on intel. 85 */ 86 87 #include <sys/types.h> 88 #include <sys/param.h> 89 #include <sys/cmn_err.h> 90 #include <sys/user.h> 91 #include <sys/vfs.h> 92 #include <sys/vnode.h> 93 #include <sys/pathname.h> 94 #include <sys/systm.h> 95 #include <sys/file.h> 96 #include <sys/stropts.h> 97 #include <sys/stream.h> 98 #include <sys/strsubr.h> 99 100 #include <sys/consdev.h> 101 #include <sys/console.h> 102 #include <sys/wscons.h> 103 #include <sys/kbio.h> 104 #include <sys/debug.h> 105 #include <sys/reboot.h> 106 #include <sys/termios.h> 107 108 #include <sys/ddi.h> 109 #include <sys/sunddi.h> 110 #include <sys/sunldi.h> 111 #include <sys/sunndi.h> 112 #include <sys/ndi_impldefs.h> 113 #include <sys/modctl.h> 114 #include <sys/ddi_impldefs.h> 115 #include <sys/ddi_implfuncs.h> 116 #include <sys/promif.h> 117 #include <sys/fs/snode.h> 118 119 #include <sys/errno.h> 120 #include <sys/devops.h> 121 #include <sys/note.h> 122 123 #include <sys/tem_impl.h> 124 #include <sys/polled_io.h> 125 #include <sys/kmem.h> 126 #include <sys/dacf.h> 127 #include <sys/consconfig_dacf.h> 128 #include <sys/consplat.h> 129 #include <sys/log.h> 130 #include <sys/disp.h> 131 132 /* 133 * External global variables 134 */ 135 extern vnode_t *rconsvp; 136 extern dev_t rwsconsdev; 137 138 /* 139 * External functions 140 */ 141 extern uintptr_t space_fetch(char *key); 142 extern int space_store(char *key, uintptr_t ptr); 143 144 /* 145 * Tasks 146 */ 147 static int kb_config(dacf_infohdl_t, dacf_arghdl_t, int); 148 static int kb_unconfig(dacf_infohdl_t, dacf_arghdl_t, int); 149 static int ms_config(dacf_infohdl_t, dacf_arghdl_t, int); 150 static int ms_unconfig(dacf_infohdl_t, dacf_arghdl_t, int); 151 152 /* 153 * Internal functions 154 */ 155 static int consconfig_setmodes(dev_t dev, struct termios *termiosp); 156 static void consconfig_check_phys_kbd(cons_state_t *); 157 static void consconfig_rem_dev(cons_state_t *, dev_t); 158 static void consconfig_add_dev(cons_state_t *, cons_prop_t *); 159 static cons_prop_t *consconfig_find_dev(cons_state_t *, dev_t); 160 static void consconfig_free_prop(cons_prop_t *prop); 161 static void flush_deferred_console_buf(void); 162 163 164 /* 165 * On supported configurations, the firmware defines the keyboard and mouse 166 * paths.
