From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What's an example? I would have thought, back then especially, their driver (and maybe nvapi) was most of the software they shipped.
My memory is fuzzy, but they have had their tegra SOC since the 2000s, and somewhat more recently they have been a big player in data center networking.
And ever since CUDA became a thing they have been a big name in HPC and super computers, which is usually Linux based.
So they have done a lot of behind the scenes Linux work (and possibly BSD?).
Yeah, afaik the tegra was only used for embedded, closed source devices though, no? Did they submit any non-proprietary tegra support upstream?
And afaik CUDA has also always been proprietary bins. Maybe you mean they had to submit upstream fixes here and there to get their closed-source stuff working properly?
Tegra was used in android tablets, I had a couple. Not sure what the licence status was, but it was supported in cyanogen, so they must have had to make some changes to the kernel for that?
Certainly some of the stuff the upstreamed was to support their drivers, but they would have also been working on other more general things to support their super computers and other HPC stuff.
They also had a chipset for intel motherboards (which I can't find anything about), which may have had some work required?
I don't really know exactly the scope of all the work, but they have been in the top 20 companies for kernel development for a long time, and I assuming it can't just be supporting their own drivers.
Its hard to find the stats, but from here: https://bootlin.com/community/contributions/kernel-contributions/ you can click through and get breakdowns per kernel release: https://web.archive.org/web/20160803012713/remword.com/kps_result/3.8_whole.html
Cool, that's a good source to peruse, thanks.
