Re: [alsa-devel] About snd_dmaengine_pcm_trigger()

Hi Lars, Mark

Make them ASoC components ;) I don't know the hardware, but looking at the code it doesn't seem to be that different from other modern host side audio processing units. But one step at a time, first maybe try and see if you can switch over to using the dmaengine PCM helper functions. Then later thing about how this all can be better integrated into the ASoC framework.

In my quick check, I guess, my drivers (FSI/rcar) can use ${LINUX}/sound/core/pcm_dmaengine.c methods as 1st step.

OTOH, these drivers has PIO transfer too. So, if ALSA has PIO method like pcm_pio.c (?) which has similar method, it seems easy to switch over. But what do you think ?
