MODERATORS
This is the best summary I could come up with:
New (Windows) tools have been released that break the NVIDIA BIOS Signature Lock, the "security" functionality in use since the GeForce GTX 900 days around signed firmware/BIOS handling.
With the NVIDIA BIOS Signature Lock being broken, a Windows utility was released today that allows for cross-flashing BIOS images on graphics cards, raising power limits on pre-Turing GPUs, and have more control around the graphics card's voltages, fan curve, and other attributes.
The Windows tools are OMGVflash and NVflashk for supporting vBIOS modding and cross-flashing with newer generations of GPUs.
The GeForce GTX 700 series is the last generation of cards to work well with the Nouveau open-source driver and not be contingent upon any extra signed firmware blobs for initialization.
Additionally, the Nouveau developers continuing to work on their kernel DRM driver are currently focused on getting the NVIDIA GPU System Processor (GSP) support in place for better handling RTX 20 series and newer hardware.
But it sure would be nice if things were still like the GeForce GTX 700 days and prior that allowed for better open-source driver support without having to worry about the security/authentication requirements.
