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.

Linux 6.6 To Better Protect Against The Illicit Behavior Of NVIDIA's Proprietary Driver (www.phoronix.com)

Luis Chamberlain sent out the modules changes today for the Linux 6.6 merge window. Most notable with the modules update is a change that better builds up the defenses against NVIDIA's proprietary kernel driver from using GPL-only symbols. Or in other words, bits that only true open-source drivers should be utilizing and not proprietary kernel drivers like NVIDIA's default Linux driver in respecting the original kernel code author's intent.

Back in 2020 when the original defense was added, NVIDIA recommended avoiding the Linux 5.9 for the time being. They ended up having a supported driver several weeks later. It will be interesting to see this time how long Linux 6.6+ thwarts their kernel driver.

Oh yes sure, the software make nvidia gpu better, something that probably most of the hundred if not thousand of contributor to the mesa driver and in the list we have amd, intel, collabora, redhat, nouveau, google, valve and many others didn't see, they were the only one in the entire silicon valley to find this secret sauce to make gpus better with software.

Yes? I'm not saying Mesa as a whole is bad, but Mesa+Nouveau for Nvidia cards is terrible.

(It doesn't help that Nvidia isn't exactly cooperative when it comes to supporting open-source developers, but my point that driver development is non-trivial stands.)

Mesa+Nouveau is bad only thanks to nvidia and their signature lock implemented since the 900 series, as even stated by me before:

the open source nvidia driver it's not able to re-clock the gpu with an higher clock than the boot one (and trust me it's a really low clock) and you are not able to use a quarter of the power the gpu has.

Even if the open source driver code is 100% equals the nvidia one, literally copy pasted, it would not work because it need to be signed by nvidia to do so.

You've convinced me. I still think that secret optimizations are a possibility, but I must concede that there might very well be this sort of lock-in bullshit and nothing else.
