<sect1><title>Digital TV Demux API</title>
<para>The kernel demux API defines a driver-internal interface for
registering low-level, hardware specific driver to a hardware
independent demux layer. It is only of interest for Digital TV
device driver writers. The header file for this API is named
<constant>demux.h</constant> and located in
<constant>drivers/media/dvb-core</constant>.</para>
<para>The demux API should be implemented for each demux in the
system. It is used to select the TS source of a demux and to manage
the demux resources. When the demux client allocates a resource via
the demux API, it receives a pointer to the API of that
resource.</para>
<para>Each demux receives its TS input from a DVB front-end or from
memory, as set via this demux API. In a system with more than one
front-end, the API can be used to select one of the DVB front-ends
as a TS source for a demux, unless this is fixed in the HW platform.
The demux API only controls front-ends regarding to their connections
with demuxes; the APIs used to set the other front-end parameters,
such as tuning, are not defined in this document.</para>
<para>The functions that implement the abstract interface demux should
be defined static or module private and registered to the Demux
core for external access. It is not necessary to implement every
function in the struct <constant>dmx_demux</constant>. For example,
a demux interface might support Section filtering, but not PES
filtering. The API client is expected to check the value of any
function pointer before calling the function: the value of NULL means
that the &#8220;function is not available&#8221;.</para>
<para>Whenever the functions of the demux API modify shared data,
the possibilities of lost update and race condition problems should
be addressed, e.g. by protecting parts of code with mutexes.</para>
<para>Note that functions called from a bottom half context must not
sleep. Even a simple memory allocation without using GFP_ATOMIC can
result in a kernel thread being put to sleep if swapping is needed.
For example, the Linux kernel calls the functions of a network device
interface from a bottom half context. Thus, if a demux API function
is called from network device code, the function must not sleep.
</para>
</sect1>
<section id="demux_callback_api">
<title>Demux Callback API</title>
<para>This kernel-space API comprises the callback functions that
deliver filtered data to the demux client. Unlike the other DVB
kABIs, these functions are provided by the client and called from
the demux code.</para>
<para>The function pointers of this abstract interface are not
packed into a structure as in the other demux APIs, because the
callback functions are registered and used independent of each
other. As an example, it is possible for the API client to provide
several callback functions for receiving TS packets and no
callbacks for PES packets or sections.</para>
<para>The functions that implement the callback API need not be
re-entrant: when a demux driver calls one of these functions,
the driver is not allowed to call the function again before
the original call returns. If a callback is triggered by a
hardware interrupt, it is recommended to use the Linux
&#8220;bottom half&#8221; mechanism or start a tasklet instead of
making the callback function call directly from a hardware
interrupt.</para>
<para>This mechanism is implemented by
<link linkend='API-dmx-ts-cb'>dmx_ts_cb()</link> and
<link linkend='API-dmx-section-cb'>dmx_section_cb()</link>.</para>

* @buffer2_length: Length of the TS data in buffer2.
* @source: Indicates which TS feed is the source of the callback.
*
* This function callback prototype, provided by the client of the demux API,
* is called from the demux code. The function is only called when filtering
* on ae TS feed has been enabled using the start_filtering() function at
* the &dmx_demux.
* Any TS packets that match the filter settings are copied to a circular
* buffer. The filtered TS packets are delivered to the client using this
* callback function. The size of the circular buffer is controlled by the
* circular_buffer_size parameter of the &dmx_ts_feed.@set function.
* It is expected that the @buffer1 and @buffer2 callback parameters point to
* addresses within the circular buffer, but other implementations are also
* possible. Note that the called party should not try to free the memory
* the @buffer1 and @buffer2 parameters point to.
*
* When this function is called, the @buffer1 parameter typically points to
* the start of the first undelivered TS packet within a circular buffer.
* The @buffer2 buffer parameter is normally NULL, except when the received
* TS packets have crossed the last address of the circular buffer and
* ”wrapped” to the beginning of the buffer. In the latter case the @buffer1
* parameter would contain an address within the circular buffer, while the
* @buffer2 parameter would contain the first address of the circular buffer.
* The number of bytes delivered with this function (i.e. @buffer1_length +
* @buffer2_length) is usually equal to the value of callback_length parameter
* given in the set() function, with one exception: if a timeout occurs before
* receiving callback_length bytes of TS data, any undelivered packets are
* immediately delivered to the client by calling this function. The timeout
* duration is controlled by the set() function in the TS Feed API.
*
* If a TS packet is received with errors that could not be fixed by the
* TS-level forward error correction (FEC), the Transport_error_indicator
* flag of the TS packet header should be set. The TS packet should not be
* discarded, as the error can possibly be corrected by a higher layer
* protocol. If the called party is slow in processing the callback, it
* is possible that the circular buffer eventually fills up. If this happens,
* the demux driver should discard any TS packets received while the buffer
* is full and return -EOVERFLOW.
*
* The type of data returned to the callback can be selected by the
* &dmx_ts_feed.@set function. The type parameter decides if the raw
* TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
* should be returned. If additionally the TS_DECODER bit is set the stream
* will also be sent to the hardware MPEG decoder.
*
* Return:
* 0, on success;
* -EOVERFLOW, on buffer overflow.

* &dmx_ts_feed.@start_filtering. When the demux driver has received a
* complete section that matches at least one section filter, the client
* is notified via this callback function. Normally this function is called

* multiple sections with one callback, for example when the system load
* is high. If an error occurs while receiving a section, this
* function should be called with the corresponding error type set in the
* success field, whether or not there is data to deliver. The Section Feed
* implementation should maintain a circular buffer for received sections.
* However, this is not necessary if the Section Feed API is implemented as

* buffers the received data. The size of the circular buffer can be
* configured using the &dmx_ts_feed.@set function in the Section Feed API.

* the section must be discarded. If this happens, the value of the success

* struct dmx_demux - Structure that contains the demux capabilities and
* callbacks.
*
* @capabilities: Bitfield of capability flags.
*
* @frontend: Front-end connected to the demux
*
* @priv: Pointer to private data of the API client
*
* @open: This function reserves the demux for use by the caller and, if
* necessary, initializes the demux. When the demux is no longer needed,
* the function @close should be called. It should be possible for
* multiple clients to access the demux at the same time. Thus, the
* function implementation should increment the demux usage count when
* @open is called and decrement it when @close is called.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* It returns
* 0 on success;
* -EUSERS, if maximum usage count was reached;
* -EINVAL, on bad parameter.
*
* @close: This function reserves the demux for use by the caller and, if
* necessary, initializes the demux. When the demux is no longer needed,
* the function @close should be called. It should be possible for
* multiple clients to access the demux at the same time. Thus, the
* function implementation should increment the demux usage count when
* @open is called and decrement it when @close is called.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* It returns
* 0 on success;
* -ENODEV, if demux was not in use (e. g. no users);
* -EINVAL, on bad parameter.
*
* @write: This function provides the demux driver with a memory buffer
* containing TS packets. Instead of receiving TS packets from the DVB
* front-end, the demux driver software will read packets from memory.
* Any clients of this demux with active TS, PES or Section filters will
* receive filtered data via the Demux callback API (see 0). The function
* returns when all the data in the buffer has been consumed by the demux.
* Demux hardware typically cannot read TS from memory. If this is the
* case, memory-based filtering has to be implemented entirely in software.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @buf function parameter contains a pointer to the TS data in
* kernel-space memory.
* The @count function parameter contains the length of the TS data.
* It returns
* 0 on success;
* -ERESTARTSYS, if mutex lock was interrupted;
* -EINTR, if a signal handling is pending;
* -ENODEV, if demux was removed;
* -EINVAL, on bad parameter.
*
* @allocate_ts_feed: Allocates a new TS feed, which is used to filter the TS
* packets carrying a certain PID. The TS feed normally corresponds to a
* hardware PID filter on the demux chip.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @feed function parameter contains a pointer to the TS feed API and
* instance data.
* The @callback function parameter contains a pointer to the callback
* function for passing received TS packet.
* It returns
* 0 on success;
* -ERESTARTSYS, if mutex lock was interrupted;
* -EBUSY, if no more TS feeds is available;
* -EINVAL, on bad parameter.
*
* @release_ts_feed: Releases the resources allocated with @allocate_ts_feed.
* Any filtering in progress on the TS feed should be stopped before
* calling this function.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @feed function parameter contains a pointer to the TS feed API and
* instance data.
* It returns
* 0 on success;
* -EINVAL on bad parameter.
*
* @allocate_section_feed: Allocates a new section feed, i.e. a demux resource
* for filtering and receiving sections. On platforms with hardware
* support for section filtering, a section feed is directly mapped to
* the demux HW. On other platforms, TS packets are first PID filtered in
* hardware and a hardware section filter then emulated in software. The
* caller obtains an API pointer of type dmx_section_feed_t as an out
* parameter. Using this API the caller can set filtering parameters and
* start receiving sections.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @feed function parameter contains a pointer to the TS feed API and
* instance data.
* The @callback function parameter contains a pointer to the callback
* function for passing received TS packet.
* It returns
* 0 on success;
* -EBUSY, if no more TS feeds is available;
* -EINVAL, on bad parameter.
*
* @release_section_feed: Releases the resources allocated with
* @allocate_section_feed, including allocated filters. Any filtering in
* progress on the section feed should be stopped before calling this
* function.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @feed function parameter contains a pointer to the TS feed API and
* instance data.
* It returns
* 0 on success;
* -EINVAL, on bad parameter.
*
* @add_frontend: Registers a connectivity between a demux and a front-end,
* i.e., indicates that the demux can be connected via a call to
* @connect_frontend to use the given front-end as a TS source. The
* client of this function has to allocate dynamic or static memory for
* the frontend structure and initialize its fields before calling this
* function. This function is normally called during the driver
* initialization. The caller must not free the memory of the frontend
* struct before successfully calling @remove_frontend.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @frontend function parameter contains a pointer to the front-end
* instance data.
* It returns
* 0 on success;
* -EINVAL, on bad parameter.
*
* @remove_frontend: Indicates that the given front-end, registered by a call
* to @add_frontend, can no longer be connected as a TS source by this
* demux. The function should be called when a front-end driver or a demux
* driver is removed from the system. If the front-end is in use, the
* function fails with the return value of -EBUSY. After successfully
* calling this function, the caller can free the memory of the frontend
* struct if it was dynamically allocated before the @add_frontend
* operation.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @frontend function parameter contains a pointer to the front-end
* instance data.
* It returns
* 0 on success;
* -ENODEV, if the front-end was not found,
* -EINVAL, on bad parameter.
*
* @get_frontends: Provides the APIs of the front-ends that have been
* registered for this demux. Any of the front-ends obtained with this
* call can be used as a parameter for @connect_frontend. The include
* file demux.h contains the macro DMX_FE_ENTRY() for converting an
* element of the generic type struct &list_head * to the type
* struct &dmx_frontend *. The caller must not free the memory of any of
* the elements obtained via this function call.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* It returns a struct list_head pointer to the list of front-end
* interfaces, or NULL in the case of an empty list.
*
* @connect_frontend: Connects the TS output of the front-end to the input of
* the demux. A demux can only be connected to a front-end registered to
* the demux with the function @add_frontend. It may or may not be
* possible to connect multiple demuxes to the same front-end, depending
* on the capabilities of the HW platform. When not used, the front-end
* should be released by calling @disconnect_frontend.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @frontend function parameter contains a pointer to the front-end
* instance data.
* It returns
* 0 on success;
* -EINVAL, on bad parameter.
*
* @disconnect_frontend: Disconnects the demux and a front-end previously
* connected by a @connect_frontend call.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* It returns
* 0 on success;
* -EINVAL on bad parameter.
*
* @get_pes_pids: Get the PIDs for DMX_PES_AUDIO0, DMX_PES_VIDEO0,
* DMX_PES_TELETEXT0, DMX_PES_SUBTITLE0 and DMX_PES_PCR0.
* The @demux function parameter contains a pointer to the demux API and
* instance data.
* The @pids function parameter contains an array with five u16 elements
* where the PIDs will be stored.
* It returns
* 0 on success;
* -EINVAL on bad parameter.
