Probably as easy as dma_data->sync_mode since OMAP_DMA_SYNC_ELEMENT is zero. The McBSP DAI must and can know the DMA parameters (like sync_mode) but otherwise (like MCBSP_DMA_MODE_xxx) it sounds unnecessary glue between the drivers. > @@ -193,9 +195,16 @@ static int omap_pcm_trigger(struct snd_pcm_substream *substream, int cmd) > struct omap_pcm_dma_data *dma_data = prtd->dma_data; > unsigned long flags; > int ret = 0; > - int samples = snd_pcm_lib_period_bytes(substream) >> 1; > + int samples; > > spin_lock_irqsave(&prtd->lock, flags); > + > + /* TODO: Currently, MODE_ELEMENT == MODE_FRAME */ > + if (dma_data->dma_op_mode == MCBSP_DMA_MODE_THRESHOLD) > + samples = snd_pcm_lib_period_bytes(substream) >> 1; > + else > + samples = 1; > + Can these lines in this patch and in patch 15 to be moved into omap_mcbsp_trigger? For me it looks it would simplify and remove the glue between the drivers. -- Jarkko -- To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
