/*
Sequencer MIDI-through client
This gives a simple midi-through client. All the normal input events
are redirected to output port immediately.
The routing can be done via aconnect program in alsa-utils.
Each client has a static client number 14 (= SNDRV_SEQ_CLIENT_DUMMY).
If you want to auto-load this module, you may add the following alias
in your /etc/conf.modules file.
alias snd-seq-client-14 snd-seq-dummy
The module is loaded on demand for client 14, or /proc/asound/seq/
is accessed. If you don't need this module to be loaded, alias
snd-seq-client-14 as "off". This will help modprobe.
The number of ports to be created can be specified via the module
parameter "ports". For example, to create four ports, add the
following option in a configuration file under /etc/modprobe.d/:
option snd-seq-dummy ports=4
The model option "duplex=1" enables duplex operation to the port.
In duplex mode, a pair of ports are created instead of single port,
and events are tunneled between pair-ports. For example, input to
port A is sent to output port of another port B and vice versa.
In duplex mode, each port has DUPLEX capability.

* ALSA sequencer Timing queue handling
* Copyright (c) 1998-1999 by Frank van de Pol <[email protected]>
*
* MAJOR CHANGES
* Nov. 13, 1999 Takashi Iwai <[email protected]>
* - Queues are allocated dynamically via ioctl.
* - When owner client is deleted, all owned queues are deleted, too.
* - Owner of unlocked queue is kept unmodified even if it is
* manipulated by other clients.
* - Owner field in SET_QUEUE_OWNER ioctl must be identical with the
* caller client. i.e. Changing owner to a third client is not
* allowed.
*
* Aug. 30, 2000 Takashi Iwai
* - Queues are managed in static array again, but with better way.
* The API itself is identical.
* - The queue is locked when struct snd_seq_queue pointer is returned via
* queueptr(). This pointer *MUST* be released afterward by
* queuefree(ptr).
* - Addition of experimental sync support.

* Port "Timer"
* - send tempo /start/stop etc. events to this port to manipulate the

* - this port supports subscription. The received timer events are
* broadcasted to all subscribed clients. The modified tempo
* value is stored on data.queue.value.
* The modifier client/port is not send.
*
* Port "Announce"
* - does not receive message
* - supports supscription. For each client or port attaching to or
* detaching from the system an announcement is send to the subscribed
* clients.
*
* Idea: the subscription mechanism might also work handy for distributing
* synchronisation and timing information. In this case we would ideally have
* a list of subscribers for each type of sync (time, tick), for each timing
* queue.
*
* NOTE: the queue to be started, stopped, etc. must be specified
* in data.queue.addr.queue field. queue is used only for
* scheduling, and no longer referred as affected queue.
* They are used only for timer broadcast (see above).

registration of client ports

/*
NOTE: the current implementation of the port structure as a linked list is
not optimal for clients that have many ports. For sending messages to all
subscribers of a port we first need to find the address of the port
structure, which means we have to traverse the list. A direct access table
(array) would be better, but big preallocated arrays waste memory.
Possible actions:
1) leave it this way, a client does normaly does not have more than a few
ports
2) replace the linked list of ports by a array of pointers which is
dynamicly kmalloced. When a port is added or deleted we can simply allocate
a new array, copy the corresponding pointers, and delete the old one. We
then only need a pointer to this array, and an integer that tells us how
much elements are in array.

*
* Each biased linear code has a leading 1 which identifies the segment
* number. The value of the segment number is equal to 7 minus the number
* of leading 0's. The quantization interval is directly available as the
* four bits wxyz. * The trailing bits (a - h) are ignored.
*
* Ordinarily the complement of the resulting code word is used for
* transmission, and so the code word is complemented before it is returned.

/* GENERAL NOTES:
*
* BUGS:
* - There are pops (we can't delay in trigger function, cause midlevel
* often need to trigger down and then up very quickly).
* Any ideas?
* - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
*/
/*
* ES1868 NOTES:
* - The chip has one half duplex pcm (with very limited full duplex support).
*
* - Duplex stereophonic sound is impossible.
* - Record and playback must share the same frequency rate.
*
* - The driver use dma2 for playback and dma1 for capture.
*/
/*
* ES1869 NOTES:
*
* - there are a first full duplex pcm and a second playback only pcm
* (incompatible with first pcm capture)
*
* - there is support for the capture volume and ESS Spatializer 3D effect.
*
* - contrarily to some pages in DS_1869.PDF the rates can be set
* independently.
*
* - Zoom Video is implemented by sharing the FM DAC, thus the user can
* have either FM playback or Video playback but not both simultaneously.
* The Video Playback Switch mixer control toggles this choice.
*
* BUGS:
*
* - There is a major trouble I noted:
*
* using both channel for playback stereo 16 bit samples at 44100 Hz
* the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
*
* The same happens using Audio1 for captureing.
*
* The Windows driver does not suffer of this (although it use Audio1
* only for captureing). I'm unable to discover why.
*
*/
/*
* ES1879 NOTES:
* - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
* seems to be effected (speaker_test plays a lower frequency). Can't find
* anything in the datasheet to account for this, so a Video Playback Switch
* control has been included to allow ZV to be enabled only when necessary.
* Then again on at least one test system the 0x71 bit 6 enable bit is not
* needed for ZV, so maybe the datasheet is entirely wrong here.

*
* This card has two mixers and two PCM devices. I've cheesed it such
* that recording and playback can be done through the same device.
* The driver "magically" routes the capturing to the AD1848 codec,
* and playback to the SB16 codec. This allows for full-duplex mode
* to some extent.
* The utilities in alsa-utils are aware of both devices, so passing
* the appropriate parameters to amixer and alsactl will give you
* full control over both mixers.

* to make it easier for some brave heart to implemt classic
