Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ * This driver is for the 'Mark Of The Unicorn' (MOTU)
+ * MidiTimePiece AV multiport MIDI interface
+ *
+ * IOPORTS
+ * -------
+ * 8 MIDI Ins and 8 MIDI outs
+ * Video Sync In (BNC), Word Sync Out (BNC),
+ * ADAT Sync Out (DB9)
+ * SMPTE in/out (1/4")
+ * 2 programmable pedal/footswitch inputs and 4 programmable MIDI controller knobs.
+ * Macintosh RS422 serial port
+ * RS422 "network" port for ganging multiple MTP's
+ * PC Parallel Port ( which this driver currently uses )
+ *
+ * MISC FEATURES
+ * -------------
+ * Hardware MIDI routing, merging, and filtering
+ * MIDI Synchronization to Video, ADAT, SMPTE and other Clock sources
+ * 128 'scene' memories, recallable from MIDI program change
+ *
+ *
+ * ChangeLog
+ * Jun 11 2001 Takashi Iwai <tiwai@suse.de>
+ * - Recoded & debugged
+ * - Added timer interrupt for midi outputs
+ * - hwports is between 1 and 8, which specifies the number of hardware ports.
+ * The three global ports, computer, adat and broadcast ports, are created
+ * always after h/w and remote ports.

+ * After receiving a interrupt, it is important to indicate to the UART that
+ * this has been done.
+ * For a Rx interrupt, this is done by reading the received byte.
+ * For a Tx interrupt this is done by either:
+ * a) Writing a byte
+ * b) Reading the IIR
+ * It is particularly important to read the IIR if a Tx interrupt is received
+ * when there is no data in tx_buff[], as in this case there no other
+ * indication that the interrupt has been serviced, and it remains outstanding
+ * indefinitely. This has the curious side effect that and no further interrupts
+ * will be generated from this device AT ALL!!.
+ * It is also desirable to clear outstanding interrupts when the device is
+ * opened/closed.
+ *
+ *
+ * Note that some devices need OUT2 to be set before they will generate
+ * interrupts at all. (Possibly tied to an internal pull-up on CTS?)

+ * VIRTUAL RAW MIDI DEVICE CARDS
+ *
+ * This dummy card contains up to 4 virtual rawmidi devices.
+ * They are not real rawmidi devices but just associated with sequencer
+ * clients, so that any input/output sources can be connected as a raw
+ * MIDI device arbitrary.
+ * Also, multiple access is allowed to a single rawmidi device.
+ *
+ * Typical usage is like following:
+ * - Load snd-virmidi module.
+ * # modprobe snd-virmidi index=2
+ * Then, sequencer clients 72:0 to 75:0 will be created, which are
+ * mapped from /dev/snd/midiC1D0 to /dev/snd/midiC1D3, respectively.
+ *
+ * - Connect input/output via aconnect.
+ * % aconnect 64:0 72:0 # keyboard input redirection 64:0 -> 72:0
+ * % aconnect 72:0 65:0 # output device redirection 72:0 -> 65:0
+ *
+ * - Run application using a midi device (eg. /dev/snd/midiC1D0)

+ * STRATEGY
+ * for playback, we send series of "chunks", which size is equal with the
+ * IBL size, typically 126 samples. at each end of chunk, the end-of-buffer
+ * interrupt is notified, and the interrupt handler will feed the next chunk.
+ *
+ * the current position is calculated from the sample count RMH.
+ * pipe->transferred is the counter of data which has been already transferred.
+ * if this counter reaches to the period size, snd_pcm_period_elapsed() will
+ * be issued.
+ *
+ * for capture, the situation is much easier.
+ * to get a low latency response, we'll check the capture streams at each
+ * interrupt (capture stream has no EOB notification). if the pending
+ * data is accumulated to the period size, snd_pcm_period_elapsed() is
+ * called and the pointer is updated.
+ *
+ * the current point of read buffer is kept in pipe->hw_ptr. note that
+ * this is in bytes.
+ *
+ *
+ * TODO
+ * - linked trigger for full-duplex mode.
+ * - scheduled action on the stream.
