Hi Nouveau developers,

NVIDIA is releasing public documentation on certain aspects of our GPUs, with the intent to address areas that impact the out-of-the-box usability of NVIDIA GPUs with Nouveau. We intend to provide more documentation over time, and guidance in additional areas as we are able.

As a first step towards that, we've posted a document here:

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

that documents the Device Control Block ("DCB") layout in the VBIOS. The DCB describes board topology and the board's display connectors.

I suspect much of the information in that document is not news for the Nouveau community, but hopefully it will be helpful to confirm your understanding or flesh out the implementation of a few unhandled cases. A few of us who work on NVIDIA's proprietary Linux GPU driver will pay attention to Questo indirizzo email è protetto dagli spambots.

If there are specific areas of documentation that would most help you, that feedback would help NVIDIA prioritize our documentation efforts.

If you have specific questions for NVIDIA, you can ask here, or direct them to: Questo indirizzo email è protetto dagli spambots. E' necessario abilitare JavaScript per vederlo. I can't promise we'll be able to answer everything, but we'll provide best-effort in areas where we are able.

Thanks, - Andy Ritger
