One fun thing on this that came up at the audio meeting we had in Dublin after ELC-E is that there is some desire to export the internal topology of audio devices to userspace using the same format that we're using to=20 load topology information for DSP firmwares (see include/sound/soc-topoloy.= h). If we go ahead with that it'd create an alternative topology ABI, it seems like we should at least consider if it's worth trying to share things here. I've not had a chance to look at the new media controller work yet, I've CCed Lars and Liam who have more knowledge in this area. Unfortunately I don't think any of the people working directly on this will be at KS this year. --H6VDMcGxLLsLVW3N Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWJPXrAAoJECTWi3JdVIfQzKsH/jWkpWnxdYJdZhrQS9kCxQDi wzjPfATTOdIs2UQjmWGJqp4RDqx5l2yaNcgImonIpxMJ/mtoFCsUYyY51njDXjXk ReZ68x+jaRThPaZiWLLwVlJib9Rtf6tUEXBZBJbSFVLY29VBhRgMI0Lu0SH8AY9g 3xhAnlxClalRCeVWBn1YeMgBfLCuwaRYqvOsGZV6qolQX/ScdefBQ0W6XVJSOAgb suttu3/F53bJ5x4dVFQ+s+OPpgR3FpJXDk56A//JCyAUQ0S2Q3OLV2Uw82ibZI6a 2k1jIOquAp51sILr58INUNKiybap3vXefl/Fmkpe2eGe+e0OZY1jy1jza35VY+M= =igK6 -----END PGP SIGNATURE----- --H6VDMcGxLLsLVW3N--
