Subject: DCB 4.1 spec update
Date: Tue, 9 Dec 2014 10:26:27 -0800	[thread overview]
Message-ID: <20141209182627.GO29251@parker.nvidia.com> (raw)

Hi,

The VBIOS on GM20x GPUs uses a slightly updated version of the DCB.
I've posted an updated DCB spec here:

ftp://download.nvidia.com/open-gpu-doc/DCB/2/DCB-4.x-Specification.html

You can diff it against the previous version:

ftp://download.nvidia.com/open-gpu-doc/DCB/1/DCB-4.0-Specification.html

to see what changed (sorry for having to diff html files).  The biggest
differences are Serial Output Resource (SOR) assignment, and the updated
Communications Control Block layout.

I hope that is helpful,
- Andy
