Northern Islands HDMI audio?

[AndyW]

Can I ask what is the state of play with HDMI audio on Northern Islands? I know it is pretty much done now for Evergreen thanks to Rafał Miłecki, but for N. I. the X.Org wiki says "Todo". My HD 4670 has pretty much given up the ghost (& doesn't seem to respond to the oven-baking trick either) so I am looking now at upgrading to "Turks" (HD 6670) as that looks like the nearest equivalent in the N. I. range and TDP should be OK for my passive HTPC case. Our main use is for HTPC TV & media playback, so 3D performance is not of great interest to us. I am also looking ahead to 3D TV...even though I know it is early days yet - HDMI 1.4 seems to be a requirement for that, which is available on N.I. h/w but not Evergreen as far as I can see.

If anyone (@zajec or Christian Konig?) is working on N. I. HDMI audio (or planning to) I am up for registry hacking, testing or anything else I can do to help. I did some of this for HD 4670 HDMI audio on radeonhd a while back. If HDMI audio is a foreseeable prospect we can manage on fglrx and/or separate audio for the time being. As stated above I would plan on purchasing HD 6670 h/w.

On the topic of HDMI 1.4, is support for that planned in radeon OSS driver, or already done - or is it all done in h/w anyway?

Regards,
Andrew

I am 6850 owner. It still doesn't support HDMI audio.

My advice is keep away from ATI cards if you want to use it on Linux with Open Sourced Radeon Drivers..
The worst thing is, it consumes ~90W extra on IDLE. Yes on IDLE.
I have to use my integrated RS780 for save power.
Even if I use echo "low" > /sys/class/drm/card0/device/power_profile, it consumes ~20 more watt than catalyst driver "using same card!"
But using "low profile" slow down GPU. And it reacts slower than my integrated GPU.
There is some automated modes available also. Like "dnypm" method. But it gives you flickers!

I don't recommend ATI to anyone until their open sourced "Power" problems fixed.

We weren't able to release the full HDMI audio implementation developed internally -- the data structures relied on some other standards where it wasn't clear we could get rights to use it in open source code -- but we did get the final bit of approval today to release register info for the blocks that control HDMI audio on newer chips. Alex pushed the patch on dri-devel earlier today :

That should include enough info to get the current code working.

DCE5 audio (Northern Islands) is identical to DCE4 audio (evergreen).

please delete your "Phoronix" account.

I don't think accounts can be deleted like that. As an alternative, how about if you set "ignore" for my username and I do the same for yours ?

Qaridarium, please stop trolling. Bridgman himself also can't help that other people at AMD aren't pro open source. Would you prefer no open source driver at all from AMD?

LOL, that may be the most outrageous statement made by Q yet.

Ha ha. Sure. Which reality would that be. The reality of Planet Andromeda.

Good to know that you're not a trolling robot but a real life person. Or should we have better not known this and treated you as a bot to be ignored?
