| |
Hi
I'm using the dmaengine API with an ASoC driver (soon to be submitted), and I have to provide a callback to ALSA to query the progress of the current transfer (the .pointer() method from struct snd_pcm_ops). Currently I only can provide this information with a period size precision. Wouldn't it make sense to add an optional hook to dmaengine for that? I certainly could add this as a platform-specific extension to the specific dmaengine driver, I'm using (shdma), but that'd be ugly. Ideas? Specific proposals for the prototype? I could cook up a patch if there are no principal objections against this.
Thanks Guennadi --- Guennadi Liakhovetski
