[src/isaki-audio2]: src/sys/dev/pci Adapt to audio2.
details: https://anonhg.NetBSD.org/src/rev/4d7ef65f6786
branches: isaki-audio2
changeset: 456016:4d7ef65f6786
user: isaki <isaki%NetBSD.org@localhost>
date: Sun Apr 28 07:48:15 2019 +0000
description:
Adapt to audio2.
- XXX In audio2, number of blocks must be 3 or greater, so
modify round_blocksize() to return bufsize / 4.
- XXX Doesn't neo_trigger_input() need to subtract ssz from
buffer end like trigger_output()?
