My spdif work: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/68594 Mathew Kanner did the original locking, which I cleaned up a bit: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/59349 The _real_ credit for my locking work goes to the horrible interactivity problems that plagued -CURRENT about a year ago. Adding locking to the driver was a desperate attempt to get sound without pauses... In any case, I've been running these changes for at least a year with no problems. I tried to pester folks into committing it many times (with no success), so I am VERY excited about this work! I don't know if you've touched the man pages at all, but my latest patch includes a man page update for the spdif sysctl: http://www.noacks.org/freebsd/es137x.diff -- Jonathan Noack | noackjr@alumni.rice.edu | OpenPGP: 0x991D8195 --------------enig91751346A6B22F460DDC6D88 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQFC0CyvUFz01pkdgZURAsHQAJ9HVA9wnVqqk8lINJ5rLpKCaweZOQCgj/PS sVJyMTuJXhBbK+osIWCdWaI= =MIrG -----END PGP SIGNATURE----- --------------enig91751346A6B22F460DDC6D88--
