Nvidia cuối cùng đã mã nguồn mở một số trình điều khiển GPU của mình. Làm thể nào để biết cái gì ẩn sau vỏ
Trong nhiều năm qua, người dùng Linux đã ghét NVIDIA, công ty dẫn đầu thế giới về Đơn vị Xử lý Đồ họa (GPU). Tại sao? Bởi vì sau nhiều năm mọi công ty khác đã mã nguồn mở trình điều khiển của họ, NVIDIA từ chối làm như vậy. Họ cũng không cung cấp dữ liệu cho các nhà phát triển kernel Linux để xây dựng trình điều khiển mã nguồn mở cho họ. Điều này khiến người dùng Linux bị mắc kẹt với trình điều khiển độc quyền, chất lượng kém. Nay, NVIDIA cuối cùng đã giới thiệu mã nguồn mở cho trình điều khiển GPU của mình.
Chủ đề hôm nay là sự kiện ngày hôm nay
For more years than I care to recall, Linux users have hated NVIDIA, the world’s leading Graphics Processing Unit (GPU) company. Why? Because years after all the other companies open-sourced their drivers, NVIDIA refused to do so. Nor would it give the Linux kernel developers the data they needed to build open-source drivers for them. That left Linux users stuck with proprietary, second-rate drivers. Now, NVIDIA has finally opened up its GPU driver code.
Hate wasn’t too strong a word. In a famous interview, a frustrated Linus Torvalds said, “I’m also happy to very publicly point out that Nvidia has been one of the worst trouble spots we’ve had with hardware manufacturers, and that is really sad because then Nvidia tries to sell chips – a lot of chips – into the Android Market. Nvidia has been the single worst company we’ve ever dealt with. (Lifts middle finger) So Nvidia, f**k you.“

And, lest we forget, in 2022, the Lapsus$ ransomware gang threatened to leak Nvidia’s GPU files if the company refused “to COMPLETELY OPEN-SOURCE (and distribute under a foss license) their GPU drivers for Windows, macOS and Linux, from now on and forever.” This was not your usual ransomware demand.
That didn’t work, but NVIDIA is transitioning fully towards open-source GPU kernel modules as it closes in on a three-trillion-dollar market cap. This marks a major change in its long-standing — and frankly wrong-headed — policy.
This transition began in May 2022 with the release of the R515 driver, which included a set of Linux GPU kernel modules as open source with dual GPL and MIT licensing. Initially, this release targeted data center compute GPUs, with GeForce and Workstation GPUs in an alpha state.
Over the past two years, NVIDIA has worked diligently to improve these open-source modules, achieving equivalent or better application performance than their closed-source counterparts. The company has also added substantial new capabilities, including:
- Heterogeneous memory management (HMM) support
- Confidential computing
- Support for the coherent memory architectures of NVIDIA’s Grace platforms
These features won’t help much with getting the best possible gaming performance, but they could assist cryptocurrency miners or artificial intelligence (AI) developers.

With the upcoming R560 driver release, NVIDIA will complete its transition to open-source GPU kernel modules. This move is expected to benefit the Linux community by allowing for better integration with the operating system and enabling more robust community development and support.
However, it’s important to note that this transition doesn’t apply to all NVIDIA GPUs. The open-source modules are mandatory for cutting-edge platforms like NVIDIA Grace Hopper or NVIDIA Blackwell. NVIDIA recommends switching to open-source modules for GPUs from the Turing, Ampere, Ada Lovelace, or Hopper architectures. Older GPUs from the Maxwell, Pascal, or Volta architectures will continue using the proprietary driver, as they’re incompatible with the open-source modules.

This move by NVIDIA is a step towards creating a more open ecosystem for Linux users and developers. It also puts NVIDIA in a better position to compete with AMD, which has long been known for its open-source-friendly approach in the Linux space.
While this is a significant development, let me remind you that NVIDIA’s transition to open-source is currently limited to the kernel modules. The driver’s userspace components remain proprietary, which means that full open-source integration, particularly for gaming applications, may still be some way off.
As the tech community digests this news, many hope this could begin a broader shift towards open-source practices at NVIDIA, potentially leading to improved compatibility and performance for Linux users.
