We can't use a ringbuffer on the chunk because it implies the consumer would write to it to update the read position, which we can't do because the chunk is read-only and might even be shared. Go back to offset/size pairs, which can sortof do the same thing if we want later when we keep a non-shared read pointer in the consumer. Keep alsa timestamp around and filled state for future. mmap the input port meta/data/chunk as read-only. Only do clock update requests when asked.
