Baytrail - Intel HDA Controller Register Documentation

TYeoh1 — Wed, 20 Apr 2016 08:16:40 GMT

Hello,

While going through the Intel BIOS Writers Guide (BWG), Section 30.7 "Additional Intel® High Definition Audio (Intel® HD Audio) Programming Steps" in Volume 2 of the Baytrail BIOS writers guide v1.44 (DocID: 514148) refers to some PCI Configuration registers in another document (DocID: 512177).

However looking at a more updated version of the "DocID: 512177" document still indicates the register documentation is missing.

The registers I am interested in are PCI configuration registers for HDA controller 0xC0,0xC4,0xC8,0xC0 & 0xD0. These registers do not exists in any of the documentation available to me.

As an developer, I prefer to understand what it is that I am configuring in the BWG.

Can anyone help clarify this?

Thank you.

Regards,

Tai

Hello TAI_YEOH

I have searched under the available documentation, but I have not being able to find the registers that you are looking for. I will consult with the next level of support about those registers.

In the meantime I would suggest that you consult on the following channels:

http://www.alsa-project.org/main/index.php/ASoC ASoC - AlsaProject

ALSA mailing list: mailto:alsa-devel@alsa-project.org alsa-devel@alsa-project.org

As there is a possibility that the Open Source Sound developers are familiar with them.

Best Regards,

Adolfo Sanchez.
