Linux-2.6.12-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!

IEEE 1394 describes a high performance serial bus, which is also
|
||||
known as FireWire(tm) or i.Link(tm) and is used for connecting all
|
||||
sorts of devices (most notably digital video cameras) to your
|
||||
computer.
|
||||
|
||||
If you have FireWire hardware and want to use it, say Y here. This
|
||||
is the core support only, you will also need to select a driver for
|
||||
your IEEE 1394 adapter.
|
||||
|

module will be called ieee1394.

/* The userspace interface for the Audio & Music Data Transmission
|
||||
* Protocol driver is really simple. First, open /dev/amdtp, use the
|
||||
* ioctl to configure format, rate, dimension and either plug or
|
||||
* channel, then start writing samples.
|
||||
*
|
||||
* The formats supported by the driver are listed below.
|
||||
* AMDTP_FORMAT_RAW corresponds to the AM824 raw format, which can
|
||||
* carry any number of channels, so use this if you're streaming
|
||||
* multichannel audio. The AMDTP_FORMAT_IEC958_PCM corresponds to the
|
||||
* AM824 IEC958 encapsulation without the IEC958 data bit set, using
|
||||
* AMDTP_FORMAT_IEC958_AC3 will transmit the samples with the data bit
|
||||
* set, suitable for transmitting compressed AC-3 audio.
|
||||
*
|
||||
* The rate field specifies the transmission rate; supported values
|
||||
* are 32000, 44100, 48000, 88200, 96000, 176400 and 192000.
|
||||
*
|
||||
* The dimension field specifies the dimension of the signal, that is,
|
||||
* the number of audio channels. Only AMDTP_FORMAT_RAW supports
|
||||
* settings greater than 2.
|
||||
*
|
||||
* The mode field specifies which transmission mode to use. The AMDTP
|
||||
* specifies two different transmission modes: blocking and
|
||||
* non-blocking. The blocking transmission mode always send a fixed
|
||||
* number of samples, typically 8, 16 or 32. To exactly match the
|
||||
* transmission rate, the driver alternates between sending empty and
|
||||
* non-empty packets. In non-blocking mode, the driver transmits as
|
||||
* small packets as possible. For example, for a transmission rate of
|
||||
* 44100Hz, the driver should send 5 41/80 samples in every cycle, but
|
||||
* this is not possible so instead the driver alternates between
|
||||
* sending 5 and 6 samples.
|
||||
*
|
||||
* The last thing to specify is either the isochronous channel to use
|
||||
* or the output plug to connect to. If you know what channel the
|
||||
* destination device will listen on, you can specify the channel
|
||||
* directly and use the AMDTP_IOC_CHANNEL ioctl. However, if the
|
||||
* destination device chooses the channel and uses the IEC61883-1 plug
|
||||
* mechanism, you can specify an output plug to connect to. The
|
||||
* driver will pick up the channel number from the plug once the
|
||||
* destination device locks the output plug control register. In this
|
||||
* case set the plug field and use the AMDTP_IOC_PLUG ioctl.
|
||||
*
|
||||
* Having configured the interface, the driver now accepts writes of
|
||||
* regular 16 bit signed little endian samples, with the channels
|
||||
* interleaved. For example, 4 channels would look like:
|
||||
*
|
||||
* | sample 0 | sample 1 ...
|
||||
* | ch. 0 | ch. 1 | ch. 2 | ch. 3 | ch. 0 | ...
|
||||
* | lsb | msb | lsb | msb | lsb | msb | lsb | msb | lsb | msb | ...

The simplest is an interface based on write(): simply write
|
||||
full DV frames of data to the device, and they will be transmitted
|
||||
as quickly as possible. The FD may be set for non-blocking I/O,
|
||||
in which case you can use select() or poll() to wait for output
|
||||
buffer space.
|
||||
|
||||
To set the DV output parameters (e.g. whether you want NTSC or PAL
|
||||
video), use the DV1394_INIT ioctl, passing in the parameters you
|
||||
want in a struct dv1394_init.
|
||||
|
||||
Example 1:
|
||||
To play a raw .DV file: cat foo.DV > /dev/dv1394
|
||||
(cat will use write() internally)
|
||||
|
||||
Example 2:
|
||||
static struct dv1394_init init = {
|
||||
0x63, (broadcast channel)
|
||||
4, (four-frame ringbuffer)
|
||||
DV1394_NTSC, (send NTSC video)
|
||||
0, 0 (default empty packet rate)
|
||||
}
|
||||
|
||||
ioctl(fd, DV1394_INIT, &init);
|
||||
|
||||
while (1) {
|
||||
read( <a raw DV file>, buf, DV1394_NTSC_FRAME_SIZE );
|
||||
write( <the dv1394 FD>, buf, DV1394_NTSC_FRAME_SIZE );
|
||||
}
|
||||
|
||||
2)
|
||||
|
||||
For more control over buffering, and to avoid unnecessary copies
|
||||
of the DV data, you can use the more sophisticated the mmap() interface.
|
||||
First, call the DV1394_INIT ioctl to specify your parameters,
|
||||
including the number of frames in the ringbuffer. Then, calling mmap()
|
||||
on the dv1394 device will give you direct access to the ringbuffer
|
||||
from which the DV card reads your frame data.
|
||||
|
||||
The ringbuffer is simply one large, contiguous region of memory
|
||||
containing two or more frames of packed DV data. Each frame of DV data
|
||||
is 120000 bytes (NTSC) or 144000 bytes (PAL).
|
||||
|
||||
Fill one or more frames in the ringbuffer, then use the DV1394_SUBMIT_FRAMES
|
||||
ioctl to begin I/O. You can use either the DV1394_WAIT_FRAMES ioctl
|
||||
or select()/poll() to wait until the frames are transmitted. Next, you'll
|
||||
need to call the DV1394_GET_STATUS ioctl to determine which ringbuffer
|
||||
frames are clear (ready to be filled with new DV data). Finally, use
|
||||
DV1394_SUBMIT_FRAMES again to send the new data to the DV output.
|
||||
|
||||
|
||||
Example: here is what a four-frame ringbuffer might look like
|
||||
during DV transmission:
|
||||
|
||||
|
||||
frame 0 frame 1 frame 2 frame 3
|
||||
|
||||
*--------------------------------------*
|
||||
| CLEAR | DV data | DV data | CLEAR |
|
||||
*--------------------------------------*
|
||||
<ACTIVE>
|
||||
|
||||
transmission goes in this direction --->>>
|
||||
|
||||
|
||||
The DV hardware is currently transmitting the data in frame 1.
|
||||
Once frame 1 is finished, it will automatically transmit frame 2.
|
||||
(if frame 2 finishes before frame 3 is submitted, the device
|
||||
will continue to transmit frame 2, and will increase the dropped_frames
|
||||
counter each time it repeats the transmission).
|
||||
|
||||
|
||||
If you called DV1394_GET_STATUS at this instant, you would
|
||||
receive the following values:
|
||||
|
||||
n_frames = 4
|
||||
active_frame = 1
|
||||
first_clear_frame = 3
|
||||
n_clear_frames = 2
|
||||
|
||||
At this point, you should write new DV data into frame 3 and optionally
|
||||
frame 0. Then call DV1394_SUBMIT_FRAMES to inform the device that
|
||||
it may transmit the new frames.
|
||||
|
||||
ERROR HANDLING
|
||||
|
||||
An error (buffer underflow/overflow or a break in the DV stream due
|
||||
to a 1394 bus reset) can be detected by checking the dropped_frames
|
||||
field of struct dv1394_status (obtained through the
|
||||
DV1394_GET_STATUS ioctl).
|
||||
|
||||
The best way to recover from such an error is to re-initialize
|
||||
dv1394, either by using the DV1394_INIT ioctl call, or closing the
|
||||
file descriptor and opening it again. (note that you must unmap all
|
||||
ringbuffer mappings when closing the file descriptor, or else
|
||||
dv1394 will still be considered 'in use').
|
||||
|
||||
MAIN LOOP
|
||||
|
||||
For maximum efficiency and robustness against bus errors, you are
|
||||
advised to model the main loop of your application after the
|
||||
following pseudo-code example:
|
||||
|
||||
(checks of system call return values omitted for brevity; always
|
||||
check return values in your code!)
|
||||
|
||||
while ( frames left ) {
|
||||
|
||||
struct pollfd *pfd = ...;
|
||||
|
||||
pfd->fd = dv1394_fd;
|
||||
pfd->revents = 0;
|
||||
pfd->events = POLLOUT | POLLIN; (OUT for transmit, IN for receive)
|
||||
|
||||
(add other sources of I/O here)
|
||||
|
||||
poll(pfd, 1, -1); (or select(); add a timeout if you want)
|
||||
|
||||
if (pfd->revents) {
|
||||
struct dv1394_status status;
|
||||
|
||||
ioctl(dv1394_fd, DV1394_GET_STATUS, &status);
|
||||
|
||||
if (status.dropped_frames > 0) {
|
||||
reset_dv1394();
|
||||
} else {
|
||||
for (int i = 0; i < status.n_clear_frames; i++) {
|
||||
copy_DV_frame();
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
where copy_DV_frame() reads or writes on the dv1394 file descriptor
|
||||
(read/write mode) or copies data to/from the mmap ringbuffer and
|
||||
then calls ioctl(DV1394_SUBMIT_FRAMES) to notify dv1394 that new
|
||||
frames are availble (mmap mode).
|
||||
|
||||
reset_dv1394() is called in the event of a buffer
|
||||
underflow/overflow or a halt in the DV stream (e.g. due to a 1394
|
||||
bus reset). To guarantee recovery from the error, this function
|
||||
should close the dv1394 file descriptor (and munmap() all
|
||||
ringbuffer mappings, if you are using them), then re-open the
|
||||
dv1394 device (and re-map the ringbuffer).

/*
|

A: DV video streams do not utilize 100% of the potential bandwidth offered
|
||||
by IEEE 1394 (FireWire). To achieve the correct rate of data transmission,
|
||||
DV devices must periodically insert empty packets into the 1394 data stream.
|
||||
Typically there is one empty packet per 14-16 data-carrying packets.
|
||||
|
||||
Some DV devices will accept a wide range of empty packet rates, while others
|
||||
require a precise rate. If the dv1394 driver produces empty packets at
|
||||
a rate that your device does not accept, you may see ugly patterns on the
|
||||
DV output, or even no output at all.
|
||||
|
||||
The default empty packet insertion rate seems to work for many people; if
|
||||
your DV output is stable, you can simply ignore this discussion. However,
|
||||
we have exposed the empty packet rate as a parameter to support devices that
|
||||
do not work with the default rate.
|
||||
|
||||
The decision to insert an empty packet is made with a numerator/denominator
|
||||
algorithm. Empty packets are produced at an average rate of CIP_N / CIP_D.
|
||||
You can alter the empty packet rate by passing non-zero values for cip_n
|
||||
and cip_d to the INIT ioctl.
