[alsa-devel] possible problem in s3c24xx-pcm.c in git-devel branch
Hi,
during the porting the uda134x driver to the git devel branch of ALSA SOC I noticed a possible problem in s3c24xx-pcm.c. s3c24xx_pcm_enqueue gained a new parameter that specifies the maximum number of periods that can be enqueued. In s3c24xx_pcm_prepare, which is called on play/capture start, this is limited to 1. Unfortunately on the 2410 the result of this change is that the DMA is stopped because the autoload of the next DMA descriptor doesn't work. I copied a log at the end of this email. Look for DMT==00 after the irq signaling the end of the first period and the subsequent fail of DMA loading since the channel is stopped.
Now I fixed with:
--- a/sound/soc/s3c24xx/s3c24xx-pcm.c +++ b/sound/soc/s3c24xx/s3c24xx-pcm.c @@ -253,7 +253,7 @@ static int s3c24xx_pcm_prepare(struct snd_pcm_substream *substream) prtd->dma_pos = prtd->dma_start;
/* enqueue dma buffers */ - s3c24xx_pcm_enqueue(substream, 1); + s3c24xx_pcm_enqueue(substream, 2);
return ret; }
but this really could be "playing with DMA" since I'm not sure why there is a 1 (since min_period is 2 I would guess 2 is the right value). Anyway with this change play and capture work well.

CCing in Dave Anders who wrote that patch (though the problem it fixes was reported previously). I can't help but think that this ought to be being dealt with within the DMA code, it all feels rather fragile.
Now I fixed with:

See the commit log - the underlying DMA code restricts the number of buffers that can be queued up prior to the start of DMA.

See the commit log - the underlying DMA code restricts the number of buffers that can be queued up prior to the start of DMA.
AFAIK it's limited to 2 transfers, one loaded and one running. It could beneficial to have more of them (so the DMA doesn't stop if one interrupt is delayed for too much time). But I don't know if it's so critical. A period (4k) with cd quality sound takes 23 ms to be played. An embedded system not responding to irqs for all this time probably has worse issues.

Yes, exactly - meaning that when DMA is idle there's only the loaded buffer.

AIUI it's a bootstrapping issue: the problem is what happens when the first DMA buffer completes if there isn't a new buffer ready. Once there's a loaded buffer ready things are happy.
I'm wondering if adding a call to s3c24xx_pcm_enqueue() in the start trigger after enabling the DMA might help matters, but I've not thought that through at all.

More info provided by Dave on IRC:
15:46 < prpplague> now the big difference between the 2410 and 2440 is ofcourse the primary clock, the 2410 generally running 200mhz whereas the 2440 is at 400mhz
...
15:49 < prpplague> i'm wondering if that when on a 200mhz s3c2410 that the second dma enqueued buffer is done, that it has been long enough for the dma channel to have started, but on the 2440 running at 400mhz it hasn't had time to start
...
16:38 < prpplague> broonie: i wonder if i clock the my s3c2440 board at 200mhz and retested if i would see the issue 16:41 < prpplague> broonie: yep, i can recreate christians problem when using the s3c2440 at 200mhz 16:42 < prpplague> broonie: and also if i use the stock code, i.e. without the enqueue limit being 1, and running at 200mhz the audio issue goes away

Hi,
to say the truth I never saw problems on the S3c2440 custom board @ 400Mhz I worked with initially:
CPU S3C2440A (id 0x32440001) S3C244X: core 399.651 MHz, memory 133.217 MHz, peripheral 66.608 MHz
Right now I cannot do much complete audio testing with it (the audio part after the codec is crippled) but I can test if dma starts and if audio playing last the right number of seconds. My initial patch was against 2.6.27 so without the limitation on the maximum period initially loading but I remembered that there were only 2 buffers loaded because the lower level dma enqueue function returned error after that. I never saw problems with aplay and madplay.
I will try to do some changes in that code but my worry is how to know how many periods are filled with data for sure by the upper ALSA layers (I'm not an expert in ASLA as you can see).

No errors were being returned - the problems were all in the audio output but the applications weren't aware of this.

It's really up to the application how much data it tries to provide.
Christian,
the enqueue patch i submitted seems to have fixed the issue on several s3c2440 based platforms. i also tested with a s3c2410 and wm8750 codec. i'll re-setup my s3c2410 platform and do some tests. in the mean time, would it be possible for you to provide me a debug log with the enqueue set as:
s3c24xx_pcm_enqueue(substream, 0);
the zero value indicates to use whatever the max dma_limit value is. i agree with Mark, that there is some core DMA issue that needs to be resolved, i'm just not sure what it is as of yet. any feedback on the issue is greatly appreciated.
thanks Dave Anders AML

From: christian pellegrin chripell@gmail.com Subject: [alsa-devel] possible problem in s3c24xx-pcm.c in git-devel branch To: alsa-devel@alsa-project.org, "Ben Dooks" ben-linux@fluff.org Date: Thursday, November 13, 2008, 8:57 AM Hi,
during the porting the uda134x driver to the git devel branch of ALSA SOC I noticed a possible problem in s3c24xx-pcm.c. s3c24xx_pcm_enqueue gained a new parameter that specifies the maximum number of periods that can be enqueued. In s3c24xx_pcm_prepare, which is called on play/capture start, this is limited to 1. Unfortunately on the 2410 the result of this change is that the DMA is stopped because the autoload of the next DMA descriptor doesn't work. I copied a log at the end of this email. Look for DMT==00 after the irq signaling the end of the first period and the subsequent fail of DMA loading since the channel is stopped.
Now I fixed with:
--- a/sound/soc/s3c24xx/s3c24xx-pcm.c +++ b/sound/soc/s3c24xx/s3c24xx-pcm.c @@ -253,7 +253,7 @@ static int s3c24xx_pcm_prepare(struct snd_pcm_substream *substream) prtd->dma_pos = prtd->dma_start;
/* enqueue dma buffers */
s3c24xx_pcm_enqueue(substream, 1);
s3c24xx_pcm_enqueue(substream, 2); return ret;}
but this really could be "playing with DMA" since I'm not sure why there is a 1 (since min_period is 2 I would guess 2 is the right value). Anyway with this change play and capture work well.

the zero value indicates to use whatever the max dma_limit value is. i agree with Mark, that there is some core DMA issue that needs to be resolved, i'm just not sure what it is as of yet. any feedback on the issue is greatly appreciated.
what issues are you seeing? The dma code is quite complicated but I haven't experienced problems yet.
