Guix port

[phodina]

NVIDIA Driver Version
Hi,
I'm porting 515.43.04 nvidia open gpu kernel module for Guix. However I face some issues in compiling the kernel module.

GPU
NVIDIA Corporation TU117GLM

Describe the bug
The build fails.
First if I don't override the build phase it fails to find the utils.mk file as
it does not run the make command from the root of the repo.

That links to second issue where the linux kernel version of the driver fails:

make -C kernel-open modules
make[1]: Entering directory 
'/tmp/guix-build-nvidia-gpu-linux-module-515.43.04.drv-0/source/kernel-open'
make[2]: Entering directory 
'/gnu/store/gcwhb3632xh588ihsddi2ss3y3v45zlz-nvidia-gpu-linux-module-515.43.04/lib/modules/5.17.5/build'make[2]:
 *** No rule to make target 'modules'. Stop.

To Reproduce
Install guix and attempt to build the package

Expected behavior
The package builds and the module is loaded into the kernel

Guix by default doesn't allow closed firmware. If you get it to build you still need a way to fetch the installer for the firmware and closed source userspace

[YusufKhan-gamedev]

I would have to guess that this driver works without the firmware anyway.

[aritger]

Thanks for your interest. I'm afraid none of us from NVIDIA have much experience with guix to be able to provide assistance. I'm going to convert this issue to a discussion, and hopefully others with more guix familiarity can help you.

[phodina]

@princesstwi Guix by default no but there are channels that support Nvidia drivers such as nonguix

Today a lots of components in the laptop/PC require firmware unfortunately.

However, it's great that the driver is now released as open source as this would mean no more fiddling with the mesa and nvda libs.

My question in general is how to build it for Guix or Nixos which are non standard distros due to their nature of using symlinks and placing everything in one location of a store to overly simplify this.

The driver might not go into official upstream but into nonguix repo.

Try running cd / && find . -name utils.mk.
