| 187 | * EVIOCGMASK - Retrieve current event mask |
| 188 | * |
| 189 | * This ioctl allows user to retrieve the current event mask for specific |
| 190 | * event type. The argument must be of type "struct input_mask" and |
| 191 | * specifies the event type to query, the address of the receive buffer and |
| 192 | * the size of the receive buffer. |
| 193 | * |
| 194 | * The event mask is a per-client mask that specifies which events are |
| 195 | * forwarded to the client. Each event code is represented by a single bit |
| 196 | * in the event mask. If the bit is set, the event is passed to the client |
| 197 | * normally. Otherwise, the event is filtered and will never be queued on |
| 198 | * the client's receive buffer. |
| 199 | * |
| 200 | * Event masks do not affect global state of the input device. They only |
| 201 | * affect the file descriptor they are applied to. |
| 202 | * |
| 203 | * The default event mask for a client has all bits set, i.e. all events |
| 204 | * are forwarded to the client. If the kernel is queried for an unknown |
| 205 | * event type or if the receive buffer is larger than the number of |
| 206 | * event codes known to the kernel, the kernel returns all zeroes for those |
| 207 | * codes. |
| 208 | * |
| 209 | * At maximum, codes_size bytes are copied. |
| 210 | * |
| 211 | * This ioctl may fail with ENODEV in case the file is revoked, EFAULT |
| 212 | * if the receive-buffer points to invalid memory, or EINVAL if the kernel |
| 213 | * does not implement the ioctl. |

| 223 | * argument-type. |
| 224 | * |
| 225 | * This ioctl provides full forward compatibility. If the passed event type |
| 226 | * is unknown to the kernel, or if the number of event codes specified in |
| 227 | * the mask is bigger than what is known to the kernel, the ioctl is still |
| 228 | * accepted and applied. However, any unknown codes are left untouched and |
| 229 | * stay cleared. That means, the kernel always filters unknown codes |
| 230 | * regardless of what the client requests. If the new mask doesn't cover |
| 231 | * all known event-codes, all remaining codes are automatically cleared and |
| 232 | * thus filtered. |

| 234 | * This ioctl may fail with ENODEV in case the file is revoked. EFAULT is |

| 448 | * struct ff_effect - defines force feedback effect |
| 449 | * @type: type of the effect (FF_CONSTANT, FF_PERIODIC, FF_RAMP, FF_SPRING, |
| 450 | * FF_FRICTION, FF_DAMPER, FF_RUMBLE, FF_INERTIA, or FF_CUSTOM) |
| 451 | * @id: an unique id assigned to an effect |
| 452 | * @direction: direction of the effect |
| 453 | * @trigger: trigger conditions (struct ff_trigger) |
| 454 | * @replay: scheduling of the effect (struct ff_replay) |
| 455 | * @u: effect-specific structure (one of ff_constant_effect, ff_ramp_effect, |
| 456 | * ff_periodic_effect, ff_condition_effect, ff_rumble_effect) further |
| 457 | * defining effect parameters |
| 458 | * |
| 459 | * This structure is sent through ioctl from the application to the driver. |
| 460 | * To create a new effect application should set its @id to -1; the kernel |
| 461 | * will return assigned @id which can later be used to update or delete |
| 462 | * this effect. |
| 463 | * |
| 464 | * Direction of the effect is encoded as follows: |
| 465 | * 0 deg -> 0x0000 (down) |
| 466 | * 90 deg -> 0x4000 (left) |
| 467 | * 180 deg -> 0x8000 (up) |
| 468 | * 270 deg -> 0xC000 (right) |
