First, it kicks off the driver loading 31 * of the console devices during boot in dynamic_console_config(). 32 * The loading of the drivers for the console devices triggers the 33 * additional device autoconfiguration to link the drivers into the keyboard 34 * and mouse console streams. 35 * 36 * The second function of this module is to provide the dacf functions 37 * to be called after a driver has attached and before it detaches. For 38 * example, a driver associated with the keyboard will have kb_config called 39 * after the driver attaches and kb_unconfig before it detaches. Similar 40 * configuration actions are performed on behalf of minor nodes representing 41 * mice. The configuration functions for the attach case take a module 42 * name as a parameter. The module is pushed on top of the driver during 43 * the configuration. 44 * 45 * Although the dacf framework is used to configure all keyboards and mice, 46 * its primary function is to allow keyboard and mouse hotplugging. 47 * 48 * This module supports multiple keyboards and mice at the same time. 49 * 50 * From the kernel perspective, there are roughly three different possible 51 * console configurations. Across these three configurations, the following 52 * elements are constant: 53 * wsconsvp = IWSCN_PATH 54 * rwsconsvp = WC_PATH 55 * consms -> msdev 56 * 57 * The "->" syntax indicates that the streams device on the right is 58 * linked under the streams device on the left. 59 * 60 * The following lists how the system is configured for different setups: 61 * 62 * stdin is a local keyboard. use stdin and stdout as the console. 63 * sp->cons_input_type = CONSOLE_LOCAL 64 * rconsvp = IWSCN_PATH 65 * wc -> conskbd -> kbddev 66 * 67 * stdin is not a keyboard and stdin is the same as stdout. 68 * assume we running on a tip line and use stdin/stdout as the console. 69 * sp->cons_input_type = CONSOLE_TIP 70 * rconsvp = (stdindev/stdoutdev) 71 * wc -> conskbd -> kbddev 72 * 73 * stdin is not a keyboard device and it's not the same as stdout. 74 * assume we have a serial keyboard hooked up and use it along with 75 * stdout as the console. 76 * sp->cons_input_type = CONSOLE_SERIAL_KEYBOARD 77 * rconsvp = IWSCN_PATH 78 * wc -> stdindev 79 * conskbd -> kbddev 80 * 81 * CAVEAT: 82 * The above is all true except for one possible Intel configuration. 83 * If stdin is set to a local keyboard but stdout is set to something 84 * other than the local display (a tip port for example) stdout will 85 * still go to the local display. This is an artifact of the console 86 * implementation on intel. 87 */ 88 89 #include <sys/types.h> 90 #include <sys/param.h> 91 #include <sys/cmn_err.h> 92 #include <sys/user.h> 93 #include <sys/vfs.h> 94 #include <sys/vnode.h> 95 #include <sys/pathname.h> 96 #include <sys/systm.h> 97 #include <sys/file.h> 98 #include <sys/stropts.h> 99 #include <sys/stream.h> 100 #include <sys/strsubr.h> 101 102 #include <sys/consdev.h> 103 #include <sys/console.h> 104 #include <sys/wscons.h> 105 #include <sys/kbio.h> 106 #include <sys/debug.h> 107 #include <sys/reboot.h> 108 #include <sys/termios.h> 109 110 #include <sys/ddi.h> 111 #include <sys/sunddi.h> 112 #include <sys/sunldi.h> 113 #include <sys/sunndi.h> 114 #include <sys/ndi_impldefs.h> 115 #include <sys/modctl.h> 116 #include <sys/ddi_impldefs.h> 117 #include <sys/ddi_implfuncs.h> 118 #include <sys/promif.h> 119 #include <sys/fs/snode.h> 120 121 #include <sys/errno.h> 122 #include <sys/devops.h> 123 #include <sys/note.h> 124 125 #include <sys/tem_impl.h> 126 #include <sys/polled_io.h> 127 #include <sys/kmem.h> 128 #include <sys/dacf.h> 129 #include <sys/consconfig_dacf.h> 130 #include <sys/log.h> 131 #include <sys/disp.h> 132 133 /* 134 * External global variables 135 */ 136 extern vnode_t *rconsvp; 137 extern dev_t rwsconsdev; 138 139 /* 140 * External functions 141 */ 142 extern uintptr_t space_fetch(char *key); 143 extern int space_store(char *key, uintptr_t ptr); 144 145 /* 146 * Tasks 147 */ 148 static int kb_config(dacf_infohdl_t, dacf_arghdl_t, int); 149 static int kb_unconfig(dacf_infohdl_t, dacf_arghdl_t, int); 150 static int ms_config(dacf_infohdl_t, dacf_arghdl_t, int); 151 static int ms_unconfig(dacf_infohdl_t, dacf_arghdl_t, int); 152 153 /* 154 * Internal functions 155 */ 156 static int consconfig_setmodes(dev_t dev, struct termios *termiosp); 157 static void consconfig_check_phys_kbd(cons_state_t *); 158 static void consconfig_rem_dev(cons_state_t *, dev_t); 159 static void consconfig_add_dev(cons_state_t *, cons_prop_t *); 160 static cons_prop_t *consconfig_find_dev(cons_state_t *, dev_t); 161 static void consconfig_free_prop(cons_prop_t *prop); 162 static void flush_usb_serial_buf(void); 163 164 165 /* 166 * On supported configurations, the firmware defines the keyboard and mouse 167 * paths.
