Aside from the firmware issues mentioned by Developer12, you would get a driver no legitimate distribution can ship because it's a copyright infringement. You need clean room reverse engineering for proper open source implementations, there's no way around that. That's also why Lapsu$' leak doesn't really matter. At most you can get some counterfeit patched version which will most likely be closed source (that scene tend to prefer keeping things closed for bragging rights or something) and may or may not contain back doors. The competition can't use it because the copyright infringement would be blatant and they risk getting sued and losing and the same applies to Mesa trying to improve Nouveau by studying or modifying that code.
But may point out that the idea is nouveau could get "inspired" by the leaked code.

My question was more in the sense of : the leaked code exposes how the driver works - this does not mean a 1:1 reengineered version is the only solution. If BMW is building a Car it is not per se a reverse engineered Maserati or vice versa. Both use Petrol engines have 4 wheels and a gearbox. That is a very simplified version of the issue.

The problem is that its naturally practically impossible to reverse engineer the current NVidia driver because its signed (in other words its encrypted) and as said before the firmware only accepts drivers that are signed. So unless someone manages to somehow break modern crypto, NVidia in any court room can very reasonable claim that the reverse engineered effort took IP from the leak because its otherwise not possible.

It should also be worth mentioning that the nvdla coprocessor can be found in the VisionFive board

s_j_newbury mentions a way, but I'm not entirely sure how far you can get without being sued anyway, considering even downloading that source code constitutes infringement.

Designing new custom hardware accelerators for deep learning is clearly popular, but achieving state-of-the-art performance and efficiency with a new design is a complex and challenging problem.
Their goal is for it to become the de facto standard in IoT. They don't plan on playing in that space, but if IoT users adopt it, Nvidia seems to anticipate up-market advantages in their bigger SoCs and training systems.
So, no. You're jumping to conclusions. Try doing a little more digging, first.Last edited by coder; 24 April 2022, 10:53 AM.
