[PATCH 0/1] reviving ack callback for 5.7(latest)

[Kuninori Morimoto]

Hi

Thank you for the patch

> ACK callback is useful to notify application pointer in DMA buffer to DSP,
> because it is called after application pointer is updated in ALSA.
> DSP can use the pointer to control preprocessing, detect underrun and so on.
> I'd like to revive it from 5.4 if it is possible.
> This patch is created in for-linus branch.

If you want to revive ACK,
post with user driver patch is nice idea IMO.
Otherwise, it will/might be removed again
because of "there is no user driver".

Thank you for your help !!

Best regards
