While this isn't quite documentation, it does give us something to reference to see how NVIDIA drives their hardware. Second: a few months ago, NVIDIA released an open-source version of their kernel driver. Dave Airlie gave a very good talk at LPC about this.

If we can get GSP working, this will allow us to use the same firmware as the proprietary NVIDIA drivers and should solve many of the mystery bugs. The GSP firmware contains everything needed for bringing up the GPU, and once the GSP firmware is loaded, it loads all the other firmwares needed by various pieces of the GPU.

Turing GPUs use a new unified firmware blob.

The first change actually happened a few years ago when NVIDIA launched their Turing class of hardware. There are a few things which have changed recently to make the technical landscape a bit more friendly. The few developer hours it gets are mostly spent on basic hardware enablement and trying to get new OpenGL versions, leaving the systemic and architectural issues unaddressed. The unfortunate reality is that, while the original nouveau drivers were written by some amazing engineers and were state-of-the-art a decade ago, they have fallen behind in the last several years. Anyone who sticks around and demonstrates significant skill and capability within either Mesa or the kernel quickly gets hired by some company to work on something that isn't nouveau and their nouveau contributions quickly drop off. Reverse-engineering is hard work and people often find something easier or more fulfilling to do and wander off.

Apart from a couple people at Red Hat who are part-time on nouveau, most of the developers who've been involved in the past several years have been volunteers doing it in their free time. Unlike the Intel and AMD drivers in Mesa, nouveau has never had strong corporate backing. This isn't really a failing of the community so much as an unfortunate effect of the economics of open-source software.

We also don't fully understand how to properly do certain things like power management, so most NVIDIA cards run at minimum clock rates all the time, leading to performance that's worse than some integrated cards.Īnother factor has been the lack of contributors. These firmware blobs were likely missing features (we have no way to know) and never got as much internal testing as the firmware used by the NVIDIA proprietary drivers, so sometimes certain cards just don't work, and we have no idea why. The firmware blobs that NVIDIA provided in the past were trimmed down versions they created just for open-source drivers.

NVIDIA hardware depends on signed firmware for everything from display to job execution to power management. Probably the biggest area of technical struggle has been properly driving the hardware from kernel space. This slows down development in the best of times and makes solving certain problems nearly impossible. Most of the hardware knowledge we (the open-source graphics community) have is learned by reverse-engineering, digging through CUDA documentation (it's amazingly low-level sometimes), and picking through the few bits NVIDIA drops us here and there.

Historically, it's been mostly focused on enabling nouveau just enough that you can install your Linux distro, get to a web browser, and download their proprietary driver stack. They occasionally provide little bits of support here. Unlike the Intel and AMD drivers, nouveau driver stack has been developed with little to no official documentation or help from NVIDIA. The nouveau drivers exist but they're often missing features, buggy, or just don't support certain cards. Support for NVIDIA hardware in open-source drivers has always been somewhat lacking. In the last month or two, we've started picking up a few commits here and there from community folks and I'm hopeful that community involvement will only increase going forward. This new driver has primarily been written by myself (Faith Ekstrand), along with Karol Herbst and Dave Airlie at Red Hat.

For the past several months, I've been working on writing a brand new open-source Vulkan driver for NVIDIA hardware in Mesa called NVK.
