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:
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 nouveau at lists.freedesktop.org and try to chime in when
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: open-gpu-doc at nvidia.com. I can't promise we'll be able to answer
everything, but we'll provide best-effort in areas where we are able.
