The driver must prepare the device 1142 * to start generating events (start polling thread, 1143 * request an IRQ, submit URB, etc.) 1144 * @close: this method is called when the very last user calls 1145 * input_close_device(). 1146 * @flush: purges the device. Most commonly used to get rid of force 1147 * feedback effects loaded into the device when disconnecting 1148 * from it 1149 * @event: event handler for events sent _to_ the device, like EV_LED 1150 * or EV_SND. The device is expected to carry out the requested 1151 * action (turn on a LED, play sound, etc.) The call is protected 1152 * by @event_lock and must not sleep 1153 * @grab: input handle that currently has the device grabbed (via 1154 * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole 1155 * recipient for all input events coming from the device 1156 * @event_lock: this spinlock is is taken when input core receives 1157 * and processes a new event for the device (in input_event()). 1158 * Code that accesses and/or modifies parameters of a device 1159 * (such as keymap or absmin, absmax, absfuzz, etc.) after device 1160 * has been registered with input core must take this lock. 1161 * @mutex: serializes calls to open(), close() and flush() methods 1162 * @users: stores number of users (input handlers) that opened this 1163 * device. It is used by input_open_device() and input_close_device() 1164 * to make sure that dev->open() is only called when the first 1165 * user opens device and dev->close() is called when the very 1166 * last user closes the device 1167 * @going_away: marks devices that are in a middle of unregistering and 1168 * causes input_open_device*() fail with -ENODEV. 1169 * @sync: set to %true when there were no new events since last EV_SYN 1170 * @dev: driver model's view of this device 1171 * @h_list: list of input handles associated with the device. When 1172 * accessing the list dev->mutex must be held 1173 * @node: used to place the device onto input_dev_list 1174 */ 1175 struct input_dev { 1176 const char *name; 1177 const char *phys; 1178 const char *uniq; 1179 struct input_id id; 1180 1181 unsigned long evbit[BITS_TO_LONGS(EV_CNT)]; 1182 unsigned long keybit[BITS_TO_LONGS(KEY_CNT)]; 1183 unsigned long relbit[BITS_TO_LONGS(REL_CNT)]; 1184 unsigned long absbit[BITS_TO_LONGS(ABS_CNT)]; 1185 unsigned long mscbit[BITS_TO_LONGS(MSC_CNT)]; 1186 unsigned long ledbit[BITS_TO_LONGS(LED_CNT)]; 1187 unsigned long sndbit[BITS_TO_LONGS(SND_CNT)]; 1188 unsigned long ffbit[BITS_TO_LONGS(FF_CNT)]; 1189 unsigned long swbit[BITS_TO_LONGS(SW_CNT)]; 1190 1191 unsigned int hint_events_per_packet; 1192 1193 unsigned int keycodemax; 1194 unsigned int keycodesize; 1195 void *keycode; 1196 1197 int (*setkeycode)(struct input_dev *dev, 1198 unsigned int scancode, unsigned int keycode); 1199 int (*getkeycode)(struct input_dev *dev, 1200 unsigned int scancode, unsigned int *keycode); 1201 int (*setkeycode_new)(struct input_dev *dev, 1202 const struct input_keymap_entry *ke, 1203 unsigned int *old_keycode); 1204 int (*getkeycode_new)(struct input_dev *dev, 1205 struct input_keymap_entry *ke); 1206 1207 struct ff_device *ff; 1208 1209 unsigned int repeat_key; 1210 struct timer_list timer; 1211 1212 int rep[REP_CNT]; 1213 1214 struct input_mt_slot *mt; 1215 int mtsize; 1216 int slot; 1217 1218 struct input_absinfo *absinfo; 1219 1220 unsigned long key[BITS_TO_LONGS(KEY_CNT)]; 1221 unsigned long led[BITS_TO_LONGS(LED_CNT)]; 1222 unsigned long snd[BITS_TO_LONGS(SND_CNT)]; 1223 unsigned long sw[BITS_TO_LONGS(SW_CNT)]; 1224 1225 int (*open)(struct input_dev *dev); 1226 void (*close)(struct input_dev *dev); 1227 int (*flush)(struct input_dev *dev, struct file *file); 1228 int (*event)(struct input_dev *dev, unsigned int type, unsigned int code, int value); 1229 1230 struct input_handle __rcu *grab; 1231 1232 spinlock_t event_lock; 1233 struct mutex mutex; 1234 1235 unsigned int users; 1236 bool going_away; 1237 1238 bool sync; 1239 1240 struct device dev; 1241 1242 struct list_head h_list; 1243 struct list_head node; 1244 }; 1245 #define to_input_dev(d) container_of(d, struct input_dev, dev) 1246 1247 /* 1248 * Verify that we are in sync with input_device_id mod_devicetable.h #defines 1249 */ 1250 1251 #if EV_MAX != INPUT_DEVICE_ID_EV_MAX 1252 #error "EV_MAX and INPUT_DEVICE_ID_EV_MAX do not match" 1253 #endif 1254 1255 #if KEY_MIN_INTERESTING != INPUT_DEVICE_ID_KEY_MIN_INTERESTING 1256 #error "KEY_MIN_INTERESTING and INPUT_DEVICE_ID_KEY_MIN_INTERESTING do not match" 1257 #endif 1258 1259 #if KEY_MAX != INPUT_DEVICE_ID_KEY_MAX 1260 #error "KEY_MAX and INPUT_DEVICE_ID_KEY_MAX do not match" 1261 #endif 1262 1263 #if REL_MAX != INPUT_DEVICE_ID_REL_MAX 1264 #error "REL_MAX and INPUT_DEVICE_ID_REL_MAX do not match" 1265 #endif 1266 1267 #if ABS_MAX != INPUT_DEVICE_ID_ABS_MAX 1268 #error "ABS_MAX and INPUT_DEVICE_ID_ABS_MAX do not match" 1269 #endif 1270 1271 #if MSC_MAX != INPUT_DEVICE_ID_MSC_MAX 1272 #error "MSC_MAX and INPUT_DEVICE_ID_MSC_MAX do not match" 1273 #endif 1274 1275 #if LED_MAX != INPUT_DEVICE_ID_LED_MAX 1276 #error "LED_MAX and INPUT_DEVICE_ID_LED_MAX do not match" 1277 #endif 1278 1279 #if SND_MAX != INPUT_DEVICE_ID_SND_MAX 1280 #error "SND_MAX and INPUT_DEVICE_ID_SND_MAX do not match" 1281 #endif 1282 1283 #if FF_MAX != INPUT_DEVICE_ID_FF_MAX 1284 #error "FF_MAX and INPUT_DEVICE_ID_FF_MAX do not match" 1285 #endif 1286 1287 #if SW_MAX != INPUT_DEVICE_ID_SW_MAX 1288 #error "SW_MAX and INPUT_DEVICE_ID_SW_MAX do not match" 1289 #endif 1290 1291 #define INPUT_DEVICE_ID_MATCH_DEVICE \ 1292 (INPUT_DEVICE_ID_MATCH_BUS | INPUT_DEVICE_ID_MATCH_VENDOR | INPUT_DEVICE_ID_MATCH_PRODUCT) 1293 #define INPUT_DEVICE_ID_MATCH_DEVICE_AND_VERSION \ 1294 (INPUT_DEVICE_ID_MATCH_DEVICE | INPUT_DEVICE_ID_MATCH_VERSION) 1295 1296 struct input_handle; 1297 1298 /** 1299 * struct input_handler - implements one of interfaces for input devices 1300 * @private: driver-specific data 1301 * @event: event handler.
