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
