| 240 | * |
| 241 | * @write: This function provides the demux driver with a memory buffer |
| 242 | * containing TS packets. Instead of receiving TS packets from the DVB |
| 243 | * front-end, the demux driver software will read packets from memory. |
| 244 | * Any clients of this demux with active TS, PES or Section filters will |
| 245 | * receive filtered data via the Demux callback API (see 0). The function |
| 246 | * returns when all the data in the buffer has been consumed by the demux. |
| 247 | * Demux hardware typically cannot read TS from memory. If this is the |
| 248 | * case, memory-based filtering has to be implemented entirely in software. |
| 249 | * The @demux function parameter contains a pointer to the demux API and |
| 250 | * instance data. |
| 251 | * The @buf function parameter contains a pointer to the TS data in |
| 252 | * kernel-space memory. |
| 253 | * The @count function parameter contains the length of the TS data. |
| 254 | * It returns |
| 255 | * 0 on success; |
| 256 | * -ENOSYS, if the command is not implemented; |
| 257 | * -EINVAL, on bad parameter. |
| 258 | * |
| 259 | * @allocate_ts_feed: Allocates a new TS feed, which is used to filter the TS |
| 260 | * packets carrying a certain PID. The TS feed normally corresponds to a |
| 261 | * hardware PID filter on the demux chip. |
| 262 | * The @demux function parameter contains a pointer to the demux API and |
| 263 | * instance data. |
| 264 | * The @feed function parameter contains a pointer to the TS feed API and |
| 265 | * instance data. |
| 266 | * The @callback function parameter contains a pointer to the callback |
| 267 | * function for passing received TS packet. |
| 268 | * It returns |

| 270 | * -EBUSY, if no more TS feeds is available; |
| 271 | * -ENOSYS, if the command is not implemented; |
| 272 | * -EINVAL, on bad parameter. |
| 273 | * |
| 274 | * @release_ts_feed: Releases the resources allocated with allocate_ts_feed(). |
| 275 | * Any filtering in progress on the TS feed should be stopped before |
| 276 | * calling this function. |
| 277 | * The @demux function parameter contains a pointer to the demux API and |
| 278 | * instance data. |
| 279 | * The @feed function parameter contains a pointer to the TS feed API and |
| 280 | * instance data. |

| 284 | * |
| 285 | * @allocate_section_feed: Allocates a new section feed, i.e. a demux resource |
| 286 | * for filtering and receiving sections. On platforms with hardware |
| 287 | * support for section filtering, a section feed is directly mapped to |
| 288 | * the demux HW. On other platforms, TS packets are first PID filtered in |
| 289 | * hardware and a hardware section filter then emulated in software. The |
| 290 | * caller obtains an API pointer of type dmx_section_feed_t as an out |
| 291 | * parameter. Using this API the caller can set filtering parameters and |
| 292 | * start receiving sections. |
| 293 | * The @demux function parameter contains a pointer to the demux API and |
| 294 | * instance data. |
| 295 | * The @feed function parameter contains a pointer to the TS feed API and |
| 296 | * instance data. |
| 297 | * The @callback function parameter contains a pointer to the callback |
| 298 | * function for passing received TS packet. |
| 299 | * It returns |
| 300 | * 0 on success; |
| 301 | * -EBUSY, if no more TS feeds is available; |
| 302 | * -ENOSYS, if the command is not implemented; |
| 303 | * -EINVAL, on bad parameter. |
| 304 | * |
| 305 | * @release_section_feed: Releases the resources allocated with |
| 306 | * allocate_section_feed(), including allocated filters. Any filtering in |
| 307 | * progress on the section feed should be stopped before calling this |
| 308 | * function. |
| 309 | * The @demux function parameter contains a pointer to the demux API and |
| 310 | * instance data. |
| 311 | * The @feed function parameter contains a pointer to the TS feed API and |
| 312 | * instance data. |
| 313 | * It returns |
| 314 | * 0 on success; |
| 315 | * -EINVAL, on bad parameter. |
| 316 | * |
| 317 | * @add_frontend: Registers a connectivity between a demux and a front-end, |
| 318 | * i.e., indicates that the demux can be connected via a call to |
| 319 | * connect_frontend() to use the given front-end as a TS source. The |
| 320 | * client of this function has to allocate dynamic or static memory for |
| 321 | * the frontend structure and initialize its fields before calling this |
| 322 | * function. This function is normally called during the driver |
| 323 | * initialization. The caller must not free the memory of the frontend |
| 324 | * struct before successfully calling remove_frontend(). |
| 325 | * The @demux function parameter contains a pointer to the demux API and |
| 326 | * instance data. |
| 327 | * The @frontend function parameter contains a pointer to the front-end |
| 328 | * instance data. |
| 329 | * It returns |
| 330 | * 0 on success; |
| 331 | * -EEXIST, if a front-end with the same value of the id field |
| 332 | * already registered; |
| 333 | * -EINUSE, if the demux is in use; |
| 334 | * -ENOMEM, if no more front-ends can be added; |
| 335 | * -EINVAL, on bad parameter. |
| 336 | * |
| 337 | * @remove_frontend: Indicates that the given front-end, registered by a call |
| 338 | * to add_frontend(), can no longer be connected as a TS source by this |
| 339 | * demux. The function should be called when a front-end driver or a demux |
| 340 | * driver is removed from the system. If the front-end is in use, the |
| 341 | * function fails with the return value of -EBUSY. After successfully |
| 342 | * calling this function, the caller can free the memory of the frontend |
| 343 | * struct if it was dynamically allocated before the add_frontend() |
| 344 | * operation. |
| 345 | * The @demux function parameter contains a pointer to the demux API and |
| 346 | * instance data. |
| 347 | * The @frontend function parameter contains a pointer to the front-end |
| 348 | * instance data. |
| 349 | * It returns |

| 351 | * -EBUSY, if the front-end is in use, i.e. a call to |
| 352 | * connect_frontend() has not been followed by a call to |
| 353 | * disconnect_frontend(); |
| 354 | * -EINVAL, on bad parameter. |
| 355 | * |
| 356 | * @get_frontends: Provides the APIs of the front-ends that have been |
| 357 | * registered for this demux. Any of the front-ends obtained with this |
| 358 | * call can be used as a parameter for connect_frontend(). The include |
| 359 | * file demux.h contains the macro DMX_FE_ENTRY() for converting an |
| 360 | * element of the generic type struct list_head* to the type |
| 361 | * dmx_frontend_t*. The caller must not free the memory of any of the |
| 362 | * elements obtained via this function call. |
| 363 | * The @demux function parameter contains a pointer to the demux API and |
| 364 | * instance data. |
| 365 | * It returns a struct list_head pointer to the list of front-end |
| 366 | * interfaces, or NULL in the case of an empty list. |
| 367 | * |
| 368 | * @connect_frontend: Connects the TS output of the front-end to the input of |
| 369 | * the demux. A demux can only be connected to a front-end registered to |
| 370 | * the demux with the function add_frontend(). It may or may not be |
| 371 | * possible to connect multiple demuxes to the same front-end, depending |
| 372 | * on the capabilities of the HW platform. When not used, the front-end |
| 373 | * should be released by calling disconnect_frontend(). |
| 374 | * The @demux function parameter contains a pointer to the demux API and |
| 375 | * instance data. |
| 376 | * The @frontend function parameter contains a pointer to the front-end |
| 377 | * instance data. |
| 378 | * It returns |
| 379 | * 0 on success; |
| 380 | * -EBUSY, if the front-end is in use; |
| 381 | * -EINVAL, on bad parameter. |
| 382 | * |
| 383 | * @disconnect_frontend: Disconnects the demux and a front-end previously |
| 384 | * connected by a connect_frontend() call. |
| 385 | * The @demux function parameter contains a pointer to the demux API and |
| 386 | * instance data. |
| 387 | * It returns |
| 388 | * 0 on success; |
| 389 | * -EINVAL on bad parameter. |
