You don't need to reply to every single comment, the general assumption will be that if there's no other followup all review comments will be addressed. It's better to just reply to things where there's something more detailed to say, if you explicitly reply to everything then that makes it easier for actual replies to be missed since there's a lot of there's a lot of the mail that's just going to be skipped through. > >>+static void ringbuf_inc(void __iomem *audio_io, bool is_playback, > >>+ const struct ringbuf_regs *p_rbuf) > >So it looks like we're getting an interrupt per period and we have to > >manually advance to the next one? > Yes. OK, so that seems fragile - what happens if we're slightly late processing an interrupt or miss one entirely? Most hardware has some way to read back the current position which tends to be more reliable, is that not an option here?
