[alsa-devel] callbacks order while capturing from Line-IN
Hi,
By now I am a bit confused.
I am seeing a certain pattern in which the callbacks are invoked:
- hw_params() - prepare() - trigger(); // Start DMA - pointer(); --> gets data after interrupt is handled - trigger(); // Stop DMA - prepare(); - trigger(); // Start DMA - pointer(); --> gets data after interrupt is handled
.. ..
and so on.
Is this the right behaviour that's expected from a function ALSA capture driver ? I am trying to understand why there is Start DMA, Stop DMA, Start DMA, Stop DMA in a cyclic fashion for each of the interrupts in my setup.
Thanks, Manu

To test my theory that a STOP cmd after an interrupt was giving me the same buffer location, I did commented out the STOP cmd, as well, allowing the START cmd to run only if the streaming engine has not START 'ed.
This allows the interrupt handler to fire correctly with the correct buffer indices, as seen in the following logs.
The problem is that,
1. I don't understand why the application issues a CMD to STOP/START, after each interrupt. 2. The STOP/START cmds reinitializes the Streaming engine to start with buffer index:0, therefore always buffer position is at the very beginning of the buffer.
Additionally, I see these lines:

The hardware information definition looks thus:
static struct snd_pcm_hardware saa7231_capture_info = { .info = (SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_INTERLEAVED | SNDRV_PCM_INFO_BLOCK_TRANSFER | SNDRV_PCM_INFO_MMAP_VALID),
.formats = SNDRV_PCM_FMTBIT_S16_LE, .rates = SNDRV_PCM_RATE_48000,
.rate_min = 48000, .rate_max = 48000,
.channels_min = 2, .channels_max = 2,
.buffer_bytes_max = XS2D_BUFFERS * PAGE_SIZE * 512, /* 16,777,216 */
.period_bytes_min = 4096, .period_bytes_max = 2097152,
.periods_min = 8, //8, .periods_max = 4096, //4096, };
Where XS2D_BUFFERS = 8
Any help is much appreciated.

I believe that your pointer callback is buggy so the midlevel code things that you had and overrun.

Thanks, that was very helpful. I am looking at it. I did find an issue looking at the pointer callback itself straight away.

The pointer should return how many samples are filled (probably value 6144 in your case). The midlevel code expects that at least one period has been recorded, but your pointer() callbacks returned 0 here. It is wrong. Ignoring STOP/START is just a bad workaround for the broken driver.

Try add some printk directly to the driver to show the few recorded samples in the DMA buffers.

Initially, I had to ignore the CMD's to understand what was happening, ie why the DMA engine was giving me buffer index:0 and hence I did ignore the START/STOP CMD's.
I did hardcoded the max frames per buffer to be 6144 (as your guess), as you can see...
stride = 768; /* meaningless in 1D mode */ buf_size = 24576; //7680; x_length = 32;// 4 /* max bytes in a line/frame/packet */ // y_length = 1920; /* max lines/frames/packets per buffer */ y_length = 6144; //1920; /* max lines/frames/packets per buffer */
SAA7231_WR(x_length, SAA7231_BAR0, module, S2D_CHx_B1_X_LENGTH(0)); SAA7231_WR(y_length, SAA7231_BAR0, module, S2D_CHx_B1_Y_LENGTH(0));
Initially, I was of the understanding that capture pointer wanted the start of the buffer and hence started with 0, 6144 and multiples of it... Now that you mention it; I modified it to return 6144 frames after each interrupt.
static snd_pcm_uframes_t saa7231_capture_pointer(struct snd_pcm_substream *pcm) { struct saa7231_audio *audio = snd_pcm_substream_chip(pcm); struct saa7231_dev *saa7231 = audio->saa7231; struct snd_pcm_runtime *rt = pcm->runtime; u32 frames, buf_size;

Eventually the arecord overrun error is gone completely

I did add a few printks, the data seems to be all 0's.
I guess the NULL data is not an Alsa related issue ? Thanks again for all the help.
