In this open-source release, support for GeForce and Workstation GPUs is alpha quality.
So there is that.

Furthermore, I hope they have sorted out security issues and the kernel driver will be able to isolate GPU-using applications from each other and from system RAM. A way too common pattern in "open source kernel drivers" is that they do nothing besides allowing a proprietary userspace library which contains all the actual driver logic to program the hardware to do whatever it wants with no kernel oversight. It used to be the case that some of those proprietary GPU drivers worked like that too.

Since it's open-source, everybody is free to have a look instead of just guessing.

I see that as an admission by NVIDIA that these drivers have always been no more than alpha quality. Perhaps by making them open source they're saying that they have no plans to spend any significant resources improving them, ever. It's sad, but it shows a tiny level of support for linux that they didn't seem to show before; they're not going to maintain the drivers themselves, but they'll provide a bare minimum of assistance helping others do the work. Better than pretending linux doesn't exist.

Since it's open sores, there is no design documentation and no hardware spec and all you have is thousands lines of code that you are welcome to try to decipher if somebody (NSA/FSB/...) is paying you for doing so :P

That is nonsense. NVidia has had Linux drivers for many of the video card for years. And these work just fine and are updated regulary. Some people obsess that the drivers aren't open source but the majority doesn't care.

This is mostly just a fix for GPL problems. If you care deeply for GPL compliance (with a very narrow definition of linking) this matters for you, if you care about open source drivers nothing has changed.

As post by some early testers...

it is a total shit show...

They just can not figure out a proper position outside the wintel and all closed shit...

I just dont buy their crap .. for years now..

While AMD (my former top list options was already ATI)  can keep a (much) better value for the money...

NV makes no sense..

It actually makes a big difference. When open source user space is updated to working with this new kernel module (Nouveau, Mesa), we will have user space with more and better features and we can actually have a kernel module that doesn't have to be compiled manually for every kernel release and driver release (DKMS sucks). It will also mean day 1 support for new graphics hardware and kernel module can be signed for secure boot. Finally Nvidia will have similar out of the box experience on the Linux desktop as Intel and AMD.

That said, all of this will take a couple of years in worst case and it only works with Turing chipset and newer (GTX 16xx, RTX 20xx and newer). But it's definitely a good start.

OK we hope for the better...   

But hardly anyone would invest some hundred buks on a promise up to some years...

NV is a multigazillion  dollars company. That said there is no excuse to promote that kind of shitty show.

They not only CAN but should (as if they care about consumers using their hw)  do better.

Otherwise.. ... well otherwise we will just accept that as a skinny dry bone to the wild..
like we love *nix we respect our consumers.. we look green good...

I was reading that what actually Nvidia seems to be doing, the scumbags they are, is pushing all the proprietary blobs to firmware, and 'open-sourcing' the kernel drivers that essentially become just call to f/w.

If one's knowledgeable enough about Linux drivers as some people here seem to be implying, then one shouldn't have any issue figuring out at least what kind of driver it is by reading the source code.

Oh and one can whine to no end about NVidia, but the market for desktop Linux is unfortunately so tiny that you can't blame a company for not dedicating significant resources to address it *to the full extent that you would like*. As others have said, proprietary drivers have been around for a couple decades on Linux and mostly work fine. The fact that they would "taint" a Linux system is sure a concern, but that never prevented people from using NVidia cards on Linux for real work. Now they released source code, but people are still going to whine. Fortunately, there are decent alternatives to NVidia, so one can stick to those if one has a problem with NVidia. Not much of an issue. It's not a monopoly.

Oh, actually Nvidia didn't released anything  :o :o :o

They just moved their precious industrial secret into a firmware embedded into a binary blob (of 34 Mbyte of size) and created a dummy wrapper around. It's what you get as "kernel driver", actually nothing more than a wrapper, an it's only the same trick used by MadWifi years ago to solve a practical problem: how to keep things embedded into a binary-blob but allowing users to recompile the kernel.

sneaky move, but useful  :-//

Not sure what you are talking about.

Firmware is stuff that runs on the GPU itself. It may or may not be open source, more often the latter.
Madwifi (and NVIDIA too) used binary blobs with "open source" wrappers as OS drivers running on the CPU.

That is technically true, but classically there wasn't a lot of programmable hardware on GPUs not externally programmed. Maybe some bios stuff and power/fan profiles and that's it. The more programming disappears into it, the less open source drivers mean. Drivers can be open source in an entirely meaningless sense.

Open source in name only.

For what it’s worth, the raspberry pi open source graphics driver uses the exact same model, ie the open source part is just a very thin wrapper around a proprietary blob.

Keyword[]={ GSP-RISC-V }

Every GPU loads a piece of firmware, but this one's hefty! 34Mbyte!!! ~900 functions implemented!!! Hence we can affirm that with NVIDIA, a *good portion* of features that AMD and Intel drivers implement in kernel are, instead, provided by a binary blob from inside the GPU, and this blob runs on the GSP, which is a RISC-V core(1).

You actually have a programmable GPU! We already have read some good article like this(2), but this NVIDIA solution looks more like the one I saw in 2001 where a RISC-like CPU was paired with a dual port ram and DAC to create a 2D accelerated video card.

It was a CPU, running software, re-programmable, not dedicated hardware.

(1) only available on Turing  and younger GPUs.
(2) General-purpose computing on graphics processing units

NVIDIA Turing : RISC-V = Rendition Vérité 1000 : V1K-RISC

The v1000 was only a slow V1K-RISC CPU @25 MHz, having a one-cycle multiplication of 32 * 32, occupying a solid part of the chip,  a one-cycle instruction for calculating the approximate inverse value, that is, a two-stroke approximated integer division, and the usual set of RISC instructions, but encoded as custom "V1K-RISC". Oh, and another “bilinear load” instruction that read a 2x2 linear memory block and performed bilinear filtering based on fractional u and v values ​​passed to the instruction. The map had a tiny cache, it seems to be only 4 pixels. Therefore, if a perfectly matching 2x2 block appeared, we received a reduction in the load on the memory bandwidth.

Very old product, rare to see, an nobody remembers open source drivers have ever really worked with x11.

There are ~20 years between NVIDIA Turing and Vérité 1000, but they really look similar: no opensource drivers, all achieved by reverse engineering the PCI binary-only drivers.

Oh, and when it somehow works, well it's always bit bumpy  :-//

Closed-source Linux kernel drivers make kernel issues undebuggable, because of the structure of the Linux kernel: a driver can do anything, and crashes usually occur somewhere else completely.  Use-after-frees, stale (incorrect) addresses scribbling over unrelated kernel memory, and so on, are typical examples of this.  (Many end users have a difficult time believing this, and insist that "my [closed source] drivers cannot be the cause, as other users would have reported it also, so it must be [code I'm responsible for]!" Yet, if the closed source drivers are never loaded in the first place, the bug does not occur... It is unbelievably frustrating for someone like me just trying to help.)

Closed firmware running on a peripheral communicating via a Linux kernel controlled bus (including address translation and DMA engines), on the other hand, poses no problems in this respect.  Besides, a typical kernel developer does not have the necessary documentation and/or hardware tools to safely develop custom firmware for arbitrary devices.

Because of this, I personally do not care much what internal firmware a graphics card might run, as long as its access to any other hardware and CPU-accessible memory is completely controlled by the Linux kernel.  As long as all code running on the CPU is open source, I can at least try to debug and fix issues, and that's good enough for me.

One problem with the infamous proprietary binary blob is long term support, especially in case of larger changes in the linux kernel. Manufacturers can drop support for their binary blob any time for any reason. When that happens and the driver requires some significant changes due to kernel changes you're stuck because you can't modify the binary blob. You could try to add some compatibility/translation layer for the outdated blob, but this would be just :horse:.

Yep, what madires wrote.

A major reason the Linux kernel is so darned versatile –– I mean, being used from phones to routers to desktops to servers to HPC clusters –– is that it is internally modular, with no stable internal APIs.  The userspace interface (syscalls, /proc and /sys pseudofilesystems) should be stable, and mostly is (with limited exceptions), but internally everything is subject to change and refactoring.  The amount of refactoring-like code churn in it is stupifying.  I mean, it is no longer possible for a single human to keep track of all the changes by themselves.  (That's why Linus delegates subsystems to proven capable developers.)

(All that said, I haven't taken a look at the sources to find out exactly what NVidia is doing; whether they open sourced just a shim, or a full kernel driver with any closed source blobs running on the GPU only.  I don't have any NVidia hardware, and prefer OpenCL over CUDA anyway, so it does not affect me right now.)

It would be darned nice to have a computing ASIC, preferably one with a large number of cores able to do 4-component Euclidean and homogenous coordinate vectors and basic vector algebra (dealing with anything 3D) and basic real and complex algebra using double precision floating-point at full speed, and a memory model with extremely fast read-only "global" memory access (data lookup) and read-write "local" memory accesses; perhaps some kind of "page" per core..  Forget about trigonometric and special functions, just super-fast, basic mathy cores in parallel.  That is what could give us a new order of magnitude of efficiency in many simulations (MD, FEM, most 3D non-field/QM stuff).  Do note that graphics doesn't need double precision; single precision suffices for human vision related stuff, but not really for the kinds of simulations I'm talking about.

That is mainly a problem caused by the Linux kernel developers by changing internal structures at will without really thinking things through. From a software maintenance perspective the Linux kernel is a hot mess so I am very gratefull for any commercial hardware vendor to have Linux support. It is not a thankfull job to keep shooting at a moving target.

To be honest, it wouldn't surprise me if every new kernel version has the same number of new bugs as the number of bugs that are fixed / features added. One example I ran into many years ago: I had a problem with a SOC that wouldn't always come out of a system reboot (reboot command). Turns out that the code to reset the power management to a voltage level where the processor could run at default speed was removed in the kernel version I happened to be using (some developers thought it was a good optimisation). It could happen the voltage regulator got set at a lower voltage just before the processor was reset through software causing the processor to get stuck (voltage too low for the frequency). Turns out this bug actually affected a few PC platforms as well.

As I just explained, "without really thinking things through" != reality.  It is actually a very common, very silly misconception.

If the Linux kernel developers did not change internal structures as needed, it would not have the capabilities or support it does have today.  Simply put, the lack of any rigid internal structure is the cost of being so versatile.  Feel free to disagree, but the above is the actual reason among Linux kernel developers; the people who actually do this stuff day in day out.

As to SBCs and Linux running on SoCs, I still haven't seen a clean, well-ordered toolchain/kernel sdk from a commercial vendor.  They look more like Linux newbie development trees, and not something put together with a sensible design.  Routers are a perfect example.  Just compare a "plain" OpenWRT installation to say Asus router images or Realtek SDK to see for yourself.  The latter are laughably messy, like something put together by a high-schooler.  Which is also the reason why I wish more people –– especially the ones who might become integrators, building such images, at some point –– would learn LinuxFromScratch, git, and historical stuff like Linux Standard Base and Filesystem Hierarchy Standard, Unix philosophy and software minimalism, and the technical reasons why so many core developers dislike systemd.  It is not that hard to do Linux integration properly; it is just that newbies (with a proprietary software background) make the same mistakes again and again.

Kernel bugs do occur, of course –– but that is because most developers today, Linux kernel developers included, are more interested in adding new functionality and features than fixing bugs and making things robust.  Userspace-breaking stuff gets reverted –– and the language Linus used to use to berate authors making such breaking changes is what so many people complained about! Pity, I liked the sharpness! ––, so it turns out that for least maintenance work, you want to be able to upgrade to newer vanilla kernels, but recommend LTS kernels you test and help maintain yourself.  It is minimal work compared to testing and maintaining your own kernel fork.

It might be that NVidia is feeling pressure on this front from the HPC field.  It is well known nowadays that if you do e.g. CUDA stuff, bug-wise you're on your own; nobody outside NVidia can actually help you.  (There is a related tale of the "tainted flag" Linux kernel uses when a binary-only driver has been loaded, and how the users who think Linux kernel developers should be telepathic and clairvoyant and be able to fix bugs even when the kernel data structures have been accessed by unknown code, believed that it should not apply to NVidia drivers, and is "just offensive"...  :palm:  See the first paragraph describing this in the Linux kernel documentation, and consider the precise and gentle language used.  Heh.)

The fact that desktop support is "alpha quality" is a big hint ;)

I think it's not only HPC but also big "machine learning" farms, particularly "cloud" ones made available for hire. They must feel at least a little uneasy about security implications of allowing network-facing applications or applications written by total strangers to call into a proprietary blob in the kernel. And of course, maintaining a tainted kernel is an extra headache too.
