Nvidia Transitioning To Official, Open-Source Linux GPU Kernel Driver (phoronix.com) 102

Nvidia is publishing their Linux GPU kernel modules as open-source and will be maintaining it moving forward. Phoronix's Michael Larabel reports: To much excitement and a sign of the times, the embargo has just expired on this super-exciting milestone that many of us have been hoping to see for many years. Over the past two decades NVIDIA has offered great Linux driver support with their proprietary driver stack, but with the success of AMD's open-source driver effort going on for more than a decade, many have been calling for NVIDIA to open up their drivers. Their user-space software is remaining closed-source but as of today they have formally opened up their Linux GPU kernel modules and will be maintaining it moving forward. [...] This isn't limited to just Tegra or so but spans not only their desktop graphics but is already production-ready for data center GPU usage.

    So it's still non-free software. RMS wouldn't use it, and neither will I.

      Honestly, I never thought we'd see the day when Nvidia open-sourced anything in their drivers. Maybe this means we'll see non-fucked-up support for Optimus in Linux without having to deal with all kinds of stupid shit.

        No, it most definitely does not.
        As someone who has been using Optimus on an open-source AMD chip, I can say hands down NVIDIA's implementation has been better.
        If anything, perhaps this will spur the open source AMD driver to not suck at it.

        The problem, ultimately, is that "Optimus" is complicated.
        There are hardware switches, and then there are software sink/sourcing through the iGPU.
        The former is easy for everyone. The latter is a bit finicky, and requires environment variables to be set before running something on the dGPU.
        On an NVIDIA system, you just setup the binary you want to run in the control panel for the app, and you're done.

        I get the impression you're not actually a regular driver of a system with a dGPU and an iGPU. I am. Both AMD and NVIDIA.

                Perhaps you missed it but the discussion here is about "Optimus". Optimus is an NV technology where you have an integrated GPU and a discrete GPU which can be switched between for power efficiency or computing performance. There is no Linux + AMD laptop shipping with such a feature. I understand that, if you completely ignore the context of the discussion, the statement that there are no laptops shipping with Linux + AMD is incorrect but it's a little difficult to participate in a discussion if you ignore t

                    AMD calls their "Optimus" solution Hybrid Graphics, and yes, they shell tons of them. Just no Linux-focused laptops do so. Being one who, like I said, uses the OSS DRI_PRIME implementation of Hybrid Graphics with a radeon on one of their laptops, I can tell why. This isn't AMDs fault. You can (with much trouble) install Catalyst drivers still, and they work similar to NV. The problem is the OSS stack sucks ass.

                      This is flatly false. The fastest RDNA2 APU there is (6900HS) is slower than the NVIDIA 1650 Max-Q, the a bottom barrel dGPU.
                      This isn't high end. This isn't a diss on the APUs- for integrated graphics, they're fucking phenomenal, but at the end of the day, they're simply lower power than even low-mid-end dGPUs.
                      For sub-1K laptops, you generally don't get a dGPU at all, so I'm not even sure how that's relevant.

                      Well where are you setting the goalposts? First it was dGPU, then you moved them so say it was dGPU system less than 5kg, now you have moved them again to say it's dGPU system with a price arbitrarily lower than $3.7k.

                This is correct. Difficulty isn't in installing it, difficulty is with how shitty the stack is for iGPU+dGPU pairing via sink/source. DRI_PRIME sucks.

                Finally, you have Intel laptop with intel integrated GPU, AMD laptops with APU, you have intel and amd laptops with nvidia ... intel cpu and amd GPU is possible, but a waste, as you can get the same performance with the APU, but in a much cheaper and less complex setup

                This is just ridiculous.
                AMD dGPU solutions are far more powerful than their APU solutions. An APU is not a replacement for a dGPU. It's an alternative where you don't need as much power, and a good one. If you're not looking to pay more power for a dGPU, and AMD CPU is a no-brainer in terms of iGPU performance.

                having said that, i had a old lenovo laptop that had intel and amd card and dGPU and iGPU worked fine in all kernel and mesa versions... but both cards were weak (15fps in war thunder in the intel, about 22 fps in the amd , this on the time war thunder version, still using the old opengl4 version, much slower than today vulkan engine )

                      Second, when the kernel change, i do not need to change anything, because intel and amd open source drivers are already in the kernel, the kernel is not released until all the included drivers are in sync with any API change ... so all the work is done behind the scene

                    You don't compile the closed driver, that's why it's closed rather than open. You don't have the source code for the closed driver so you can't compile it. If you are trying to feed the closed binary to the compiler then I'm not surprised you're having problems.

Making your drivers entirely open source exposes these cheats. Their cheats have repeatedly been exposed, for decades. If they're moving away frm this practice, good.

            But you can't cheat games, if they did well in synthetic benchmarks but poorly in real world games then that would be clear. The fact is the driver does contain application-specific optimizations regardless of what that application is. Yes there are optimizations for benchmarks but that's because there are also optimizations for games and content creation applications.

              In this case, NVidia may or may not be more guilty of cheating than AMD. But publishing drivers as open source can make cheating, or previous cheating, more apparent, and provides motivation to keep the drivers closed..

If the driver is closed and in the kernel, it could do anything. If the driver is open but the firmware is closed, then the driver is at least auditable, and without its cooperation the device can only do what the IOMMU permits it to do.

    Lets all check the temperatures over there.

    It's just the kernel module. The place where the real stuff happens, the xorg drivers, nvidia will probably never open source.

    This does make things easier for them though. You still need to check whether the xorg driver supports the xorg or wayland version you're using.

    One half truth is one whole lie. Here's the whole truth: without the userspace stuff, the kernel module is still completely useless.

    • the user side is the easiest to hammer together with any examples IF you have the kernel side. not many will attempt to make a driver from scratch and to use wayland and xorg either or?

    • by Anonymous Coward

      There's already nvidia support in the user-space, but because you couldn't change clock speeds, using open source drivers were incredibly slow. Open sourcing the kernel side allows changing the clock speeds, so this is a huge deal.

      That is true - the userspace is probably a more critical part of a 3D graphics stack now.

      After all, most of the processing heavy lifting happens in the userspace and application side - the kernel driver is pretty much reduced to feeding the beast.

      Think about things like Vulkan - compiling shaders and such to run on the chip is a userspace task - your Vulkan application feeds the shader code to the compiler (supplied by GPU vendor), and gets back a compiled binary. It then engages with the kernel driver to load the binary onto the GPU hardware. At which point which side did more work - the kernel loading stuff into memory on the GPU or the userland which took the shader code from the application and compiled it?

      Modern GPUs are basically highly micro-programmed parallel processors - there are fewer and fewer fixed-function blocks and more of the graphics pipeline is handled by chunks of code.

      It wouldn't surprise me if most of the open-sourced parts was stuff you had to write to manage the card hardware, and very little of it manages the actual graphics pipeline.

      In other words, nVidia moved most of the heavy lifting and binary stuff out of the kernel into userspace, letting them get rid of the binary blob that's probably doing very little on modern hardware. The rest is either handled by the firmware on the GPU or binary executables running in userspace.

    This is, IMHO, also a somewhat too little, too late...

    You were pushed to it by the DMA-BUF (by the lack of access to, due being closed source and DMA-BUF a GPL-only feature), by losing many big projects due to the lack of open drivers (steam deck, game consoles, big clusters and even datacenters), by looking bad for all these years where AMD and Intel had both open drivers (and even all ARM gpu companies are doing it already) and AMD open driver actually being better than the close source (so nullify the idea that open drivers are always much weaker than close source)... but the lack of proper open user space, still years before being merged in the kernel (if ever, needs open source user space using it to even qualify and pass all code reviews) and being 7 years late is still bad...

          Of course, this reorganization also paves the way for distribution inclusion. linux-firmware package contains lots of unmodified binary redistribution allowed content.

          Quality wise it sounds like they aren't ready for that yet, but it is a model consistent with a lot of other devices with proprietary hot-plug firmware.

          So while not perfect, it's pretty consistent with most hardware that has proprietary on-device code executing, including hard drives, network chips, even the processors themselves.

    Can't say I care all that much. Even aside from the fact that the userland portion of the driver (i.e. most of it) is still closed-source proprietary binary blob, this new kernel module requires Turing (e.g. RTX 20xx series cards) or newer.

    My current nvidia video cards are a 1060, a 970, and couple of 750s (Turing was too expensive to bother with, and Ampere was even worse). They won't be supported, and I've already decided that unless there's some major fuckup with the pricing or availability of next-gen cards, my next GPU upgrade will be to RDNA3's low-end Navi 33 - a 7600 or 7700 or whatever they end up being called.

    Given that a low-end navi 33 is supposed to be roughly comparable in performance to a current high-end 6900 XT or RTX 3090, that will be a massive performance boost compared to my current 1060 6GB. That will be overpowered for what I currently need, as I have a 1440p 60Hz monitor and won't be upgrading to a 4K monitor for quite some time.

    • Most important comment in the thread. Only the latest and previous generation cards will be supported. 16xx/20xx are both using Turing.
    • Can't say I care all that much. Even aside from the fact that the userland portion of the driver (i.e. most of it) is still closed-source proprietary binary blob

      More critically the userland portion of the driver is where 95% of everything happens. Every time a new game is released NVIDIA don't push out a new game ready driver because something fundamentally changed the way the kernel needs to talk to the hardware. No it all happens a level above.

      An open source driver in this case is kind of like running Windows inside a VM on a Linux kernel and talking about how OSS friendly you are.
