NVIDIA Releases Drivers With Openness Flavor

May 13, 2022 by Arya Voronova 27 Comments

This year, we’ve already seen sizeable leaks of NVIDIA source code, and a release of open-source drivers for NVIDIA Tegra. It seems NVIDIA decided to amp it up, and just released open-source GPU kernel modules for Linux. The GitHub link named open-gpu-kernel-modules has people rejoicing, and we are already testing the code out, making memes and speculating about the future. This driver is currently claimed to be experimental, only “production-ready” for datacenter cards – but you can already try it out!

The Driver’s Present State

Of course, there’s nuance. This is new code, and unrelated to the well-known proprietary driver. It will only work on cards starting from RTX 2000 and Quadro RTX series (aka Turing and onward). The good news is that performance is comparable to the closed-source driver, even at this point! A peculiarity of this project – a good portion of features that AMD and Intel drivers implement in Linux kernel are, instead, provided by a binary blob from inside the GPU. This blob runs on the GSP, which is a RISC-V core that’s only available on Turing GPUs and younger – hence the series limitation. Now, every GPU loads a piece of firmware, but this one’s hefty!

Barring that, this driver already provides more coherent integration into the Linux kernel, with massive benefits that will only increase going forward. Not everything’s open yet – NVIDIA’s userspace libraries and OpenGL, Vulkan, OpenCL and CUDA drivers remain closed, for now. Same goes for the old NVIDIA proprietary driver that, I’d guess, would be left to rot – fitting, as “leaving to rot” is what that driver has previously done to generations of old but perfectly usable cards.

NVIDIA 1060 with Udoo Single Board Computer

Single Board Computer Plays Nice With NVIDIA GPU

It’s about convenience when it comes to single board computers. The trade-off of raw compute power for size means the bulk of them end up being ARM based, but there are a few exceptions like the x86 based Udoo Ultra. The embedded Intel 405 GPU on the Udoo Ultra is better than most in the category, but that won’t begin to play much of anything outside of a browser window. Not satisfied with “standard” [Matteo] put together his build combining an Udoo x86 Ultra with a NVIDIA 1060 GPU. It seems ridiculous to have an expansion card almost three times longer than the entire computer its attached to, but since when did being ridiculous stop anyone in the pursuit of a few more polygons?

M.2 adapter board trim comparison — M.2 to PCIe adapter board (Top) Trimmed adapter board (Bottom)

Since the Udoo Ultra doesn’t feature a PCIe slot [Matteo] slotted in a M.2 to PCIe adapter board. There are two PCIe lines accessible by the Udoo Ultra’s M.2 port although trimming the adapter board was required in order to fit. The PCIe female slot was cut open to allow the 1060 GPU to slide in. All of the throughput of the 1060 GPU wouldn’t be utilized given the Udoo Ultra’s limitations anyway.

Windows 10 was the OS chosen for the machine so that all those NVIDIA drivers could be installed, and there’s also the added benefit of being able to sneak in a little Trackmania Turbo too. So to accompany the build, [Matteo] created a graphics comparison video to show the remarkable improvement over the embedded graphics chip. You can see the Time Spy benchmark results in the video below.

Hackaday Links: February 11, 2018

Are you a student? Are you part of a hackerspace? We have a contest going on right now where you can win a fancy new Prusa i3 MK3. The Repairs You Can Print contest is a challenge to do something useful with that machine that spits out tugboats. We’re looking for functional repairs of items around your house, office, or garage. Did you repair something with a 3D printer? Then you too can get in on the action! Enter now! Check out the entries!

You may know Flite Test as the group who do everything surrounding remote control flight (mostly fixed wings, a nice counter to the quadification of the hobby over the last few years). Flite Test designs and sells airplanes made out of Dollar Tree foam board, they have yearly, bi-coastal meetups, and they’re all-around awesome dudes. Now, they want to build the Disneyland of RC flight. [Josh Bixler], the face of Flite Test and a guy who has a plane named after him, wants to buy a golf course and turn it into the world’s best RC flying park, with a ~2000 foot grass strip for general aviation. We’re looking at their crowdfunding campaign, ~~and it looks promising~~ it might be funded by the time this goes live.

A while ago, [Peter Jansen], the guy who built a tricorder and a laser-cut CT scanner, made a magnetic camera. This Hall Effect camera is a camera for magnetism instead of light. Now, this camera has been fully built and vastly improved. He’s capturing ‘frames’ of magnetism in a spinning fan at 2000 Hz (or FPS, terminology kind of breaks down here), and it’s beautiful.

Oh thank God we can finally buy GPUs again. Try buying them with Bitcoin.

In the last few years, CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, has expanded. Originally, this was one of the treaties that banned the import or export of rhino horn, but recently this expanded to the export of rosewood thanks to increased demand in China for rosewood furniture. The laws of unintended consequences kicked into effect, and importing anything made out of rosewood is now a mess of permits and inspections at the border, including musical instruments. Travelling orchestras, for example, are at risk of having their string section confiscated because of rosewood tuning pegs. Cooler minds may now be prevailing, and there’s some hope the regulations may be changed during the next meeting of the CITES convention next year.

As noted a few months ago, there was a possibility of Broadcom buying Qualcomm for one… hundred… Billion dollars. This offer was rejected, with Qualcomm saying the offer wasn’t high enough. Broadcom fired back with an offer of $82 per share, or $121B. This offer was rejected this week.

Need some EMC testing? [Zach]’s got your back. He’s reserved some time in a 10m EMC chamber for testing NeuroBytes this week. If you have an Open Source project that needs a pre-test scan for unintentional radiator, you can get in on the action. This is just a pre-test, you’re not getting certification, and you’re not going to test anything with radios, and you need to ship [Zach] your stuff. But still, free test time. Woo.
