Any updates? 🙄

There's no stable release to package yet. The open-source kernel driver 515.43.04 is currently in alpha (for desktop use) ¹ and requires matching userspace components that are in beta ².

515.48.07 was released today as the first stable open source NVIDIA driver. I hope to see it in the repositories soon (:

I'll look at making it an option. For now, I think we'll continue to ship the proprietary kernel modules due to their wider hardware support.

The proprietary flavor supports the GPU architectures Maxwell, Pascal, Volta, Turing, Ampere, and forward.

The open flavor of kernel modules supports Turing, Ampere, and forward. The open kernel modules cannot support GPUs before Turing, because the open kernel modules depend on the GPU System Processor (GSP) first introduced in Turing.

It would be nice.

[abenson]

Out of curiosity, what GPU do you have, and are you on an Optimus system?

I am using a desktop GTX 1660 Super, it is supported by open source drivers. I use Sway and the old driver (current in Void repositories) causes artifacts when using it. In Arch Linux, thanks to the new driver, Sway works fine.

Is there any progress with this?

currently i am trying (i have no deep knowledge of DKMS or void-packages) to package this and have no clue how to make it build the modules if it requests a existing kernel

If I am not mistaken, you need to export KERNEL_UNAME. Here's how it's done in KISS Linux.

[sewnie]

the way xbps-src works is it is built in a chroot or a different system from the host system.
doing this is impossible,

kiss(1) and makepkg(1) both use the host system as the builder.

edit: i really can't seem to figure out a way to make this build for the system's kernel. @abenson can you help?

[sewnie]

it seems i am getting somewhere:

~  $ doas dkms install -m nvidia-open -v 515.49.06                                 

Kernel preparation unnecessary for this kernel.  Skipping...
