I'll apply the patch against 3.12 and will report back if it works.

Well, there is no actual behavior difference between
AZX_DRIVER_ATIHDMI and AZX_DRIVER_GENERIC about AMD HDMI chips. The
codec-probing is pretty same. The only difference in the current code
is the driver name string and the fallback of number of streams, but
the latter is valid only when GCAP register doesn't give proper
values, and it shouldn't happen with a proper chip.
That being said, the entries weren't added intentionally just because
they aren't needed to be added explicitly. The generic entry suffices
from the functionality POV.
But it seems that people misunderstand, so I think it's fine to apply
your patch to give a more clear name.

The ATI card did not show up as "ATI", but the other ATI card without
HDMI did: <http://thread.gmane.org/gmane.linux.alsa.user/37732>.
Anyway, let's close this thread:

ALSA: hda: add device IDs for AMD Evergreen/Northern Islands HDMI
The device IDs of the AMD Cypress/Juniper/Redwood/Cedar/Cayman/Antilles/
Barts/Turks/Caicos HDMI HDA controllers were missing for some reason.
Add them so that the name shows up properly as "ATI HDMI" instead of
"Generic", and so that the driver does not try to detect nonexistent
codecs.
According to Takashi's tests and the lack of complaints, these devices
work fine without disabling snooping.

The card shown as "Generic" is actually yet another AMD HDMI chip.
And this should work without the snooping. Unless you hear any
audible problems, no reason to fix this one.
Another "HDA ATI HDMI" one is tied with a different graphics unit.
I don't know what hardware configuration you have. Do you have
multiple AMD graphics cards? Basically each HDMI audio entry is tied
with the dedicated graphics chip (board). You wanted to play back via
this HDMI and it didn't work?

That's why I started asking :) The recent code should cover known
issues of AMD HDMI codecs, at least. But if there is a new chip, we'd
need to test and add the corresponding entry.

I was specifically trying to get clarification on which parts needed the snoop flag. Is there some other larger issue? From the feedback I've seen lately, audio has been working pretty well on AMD GPUs with Anssi's patches.

OK, then could you alsa-info.sh output?
The situation in the upstream has changed since we have a lot more
AMD-specific HDMI codes in the latest driver for 3.13 kernel. So,
it's not only a matter of snoop flag.

the original issue is that wen using an ATI gpu with hdmi in it, rerouting the sound via the ati hdmi card doesn't work, only via the generic.
alsa devs pointed out that the ati cards listed in intel_hda.c aren't updated with latest cards due to insufficient info on about the cards.
Alex Deucher from AMD's dev answered that he will query the right team in his workplace but no response was received fro him yet.

Well, what's your original issue?
I wasn't in the loop from the beginning, so I don't know what is the

If disablement of the snoop is mandatory on your board, we need to add
the workaround in the driver no matter what spec says. (The datasheet
is often wrong in practice :)

Thanks for the information.
Though, it's strange that the information doesn't match with what I've
heard (and also with what I've tested with a laptop). I've heard that
it's Southern Island HDMI that needs the snoop-disablement.
Could you ask again whether it's really Evergreen / Nothern Islands?
thanks,

According to our internal teams, disabling snooping is only required on the audio parts included in Evergreen and Northern Islands GPUs. Older chips like R7xx (aa48) and newer chips like Southern Islands (aaa0) are able to use snooping. I'm not real familiar with the audio portions of the GPUs so if you need further clarification, let me know.

Most of HD-audio controller have a snoop control, but the recent AMD
HDMI audio controller don't have the feature, thus the driver must use
the non-cached pages. At least, PCI ID 1002:aaa0, aaa8 and aab0 are
known to require such.
Now the question is whether all new chips above (aa50,...) require the
same workaround, too. Could you check this or forward the inquiry to
someone in AMD?
FWIW, such a chip needs to set AZX_DRIVER_ATIHDMI_NS bits in
driver_data of pci entries in sound/pci/hda/hda_intel.c.

Takashi

Coherent memory accesses, i.e., not setting bit 18 in the stream
descriptor control register; the HDA spec says:
| Traffic Priority (TP): If set to a 1, the stream will be treated as
| preferred traffic if the underlying bus supports it. If set to a 0,
| the traffic will be handled on a “best effort” basis. [...]
| On PCI Express, for example, setting the TP bit to a 1 might cause
| the controller to generate non-snooped isochronous traffic, while
| a PCI implementation may ignore this bit.
| It is permitted to implement this bit as RO if there is no
| controllability available.
So "require" might be wrong, this is just an optimization. Anyway,
devices up to aa48 use snooping, while from aaa0 (Tahiti XT) forward,
the driver sets TP (<http://git.kernel.org/linus/1815b34a6267>).
The question is, what was the first device to support this?
Regards,
Clemens
