I've just played some music over HDMI using radeon KMS and RV730 card! My local patch rewrites the way we choose HDMI block for encoder, drops current hacks and make it work on more hardware. Plus of course it adds some single bits for DCE 3.2 GPUs. It needs some cleaning, splitting maybe and fixing resume. I hope to post it in day or two, hopefully in time for getting it into 2.6.34 :)

Hi, I think this has already been completed upstream. They're just waiting on an IP Review before releasing the code
That being said I'm looking forward to trying out your patch :D

@FireBurn: that's right, patches are "ready", but didn't pass IP review since December or even longer. Fortunately we grabbed enough info (RE mostly) that allowed us to implement that anyway. It was quite easy after understanding encoder vs. transmitter difference actually :) Simple reading radeon_encoders.c gave great hints.
Unfortunately we still have no idea how to handle audio interrupts and we use timer instead. Maybe I'll dig into this later. AFAIK it was also covered by written-not-released patch.

Well if you need some testing done, especially seeing as I had so many issues with the original code (aka green screen of doom) I'll happily test out any patches before you mainline them
mike at fireburn dot co dot uk if you do
Cheers

Please release this patch soon. I have a r700/hd4000 that I thought was supported and have been trying to get hdmi audio to work on for a week now (since the hdmi sound card shows up in alsa and everything, just no volume comes out when select.)
I was about to buy a usb soundcard to get digital out to work before I read this.

Do you have a pay-pal account I could make a donation too?
zajec ─ 15.03.2010 ─ 08:22
As I said, I released this day or two after announcement. However this was ignored and probably won't be commited, because "we" prefer to wait for AMD... Which may finish IP review same day and provide own patches covering this functionality (and more audio stuff).
@mod: I don't have pay-pal and it would be unfair to get any money if I can not guarantee my patches will ever hit kernel tree.

I understand not releasing the drivers you wrote, part of working with a team.
Is there any way to donate to the xf86-video-ati group in general? I use the drivers every-day and without you guys would have to run a old version of xorg and the ATI proprietary driver.
