[PATCH] add new Fermi 5xx codec IDs to snd-hda

[PATCH] add new Fermi 5xx codec IDs to snd-hda

[Richard Samson]

Hello,

It's my first patch/post here, i'm not sure if this list is the right
place to suggest this patch.

To follow up a previous commit on snd-hda :
http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commitdiff;h=9cf2657d05f9f9e04c3e113d68bf7cef5a942070

I added a new entry in patch_hdmi.c to get sound working on my own 560
Ti card :

I think other 5xx cards need new value also.

Hmm. When I submitted that last patch, I think I looked at the wrong branch
of our Windows drivers, and hence missed a couple IDs, and added a couple of
IDs that won't be used. Once this is merged, I'll follow up with another
patch to fix the other issues (or let me know if you just want me to provide
a single patch with everything in it, Takashi).

Thanks Richard.

Richard, could you your sign-off for merging to the upstream?
See $LINUX/Documentation/SubmittingPatches,  "Sign your work" section.

I don't mind in either way as long as it's a simple patch.
As I already asked Richard for re-submitting with his sign-off,
we can wait for a while.

BTW, this kind of id addition patch can be still merged in 2.6.38
if the chips listed there are real ones.

Hello,

Thank you for your replies.

As Stephen Warren said, a patch with full support of 5xx cards will be
more useful.
I'll be able to write a new patch but I don't have the knowledge to
get other IDs.

OK, Stephen, could you prepare the patch including all missing IDs?

Hello,

I wrote an new patch with three new codec IDs for Nvidia Fermi cards.
I attended to use existing IDs and online technical specifications to
get two others cards :
- Nvidia GeForce GTX 470 : id = 0x10de0015
- Nvidia GeForce GTX 560 Ti : id = 0x10de0016 (works fine)
- Nvidia GeForce GTX 570 : id = 0x10de0017

Stephen, could you confirm these new IDs are correct ?

This patch applies on 2.6.38-rc6 and trunk.

They don't appear to match our Windows driver. Where did you get the values
from? (0x17 isn't in the Windows driver at all. 0x15 shouldn't be a GTX 470)

I ask to a reseller, it seems a bad idea.
If I can help, where are these values in the Windows driver ?

The only way to find the values that I know of would be to plug the card
in, run Linux, and look at the ALSA /proc files. (Perhaps there's some
equivalent tool under Windows)

> If I can help, where are these values in the Windows driver ?

They encoded into the binary. I doubt they're user-accessible.

So, I think the best way to proceed is for you to modify your patch to add
IDs 0x15 and 0x16 only. I'm pretty sure ID 0x17 isn't assigned to anything.
Let's not remove any NVIDIA IDs even though I'm pretty sure a couple aren't
actually assigned; if I'm wrong, we'd just have to add them back later, and
having them in won't harm anything.

Thanks.
