Unable to allocate RAM for VRAM when VRAM is full

NVIDIA Open GPU Kernel Modules Version

nvidia-open-dkms 595.58.03

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.

Operating System and Version

Cachyos

Kernel Release

Linux-LTS 6.18.19

Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.

• I am running on a stable kernel release.

Hardware: GPU

NVIDIA GeForce RTX 4060 Ti OC 8GB

Describe the bug

When running games or applications, if the VRAM becomes full apps will freeze up or crash. Also when trying to open anything with the VRAM full those programs will crash upon opening them. When checking the logs it appears that there is many failures related to the allocation of the RAM.

To Reproduce

Just try to use as much VRAM as possible by running things like Memtest Vulkan alongside something else like a game or other apps. I find that it triggers at 7.8-7.9 GB usage.

More Info

I have a friend who has an AMD GPU running on CachyOS that seems to handle full VRAM just fine, sure it has some graphical bugs here and there, but I feel that it would be better then crashing at least. Also unable to test this with the proprietary driver because CachyOS no longer properly supports it. Edit: I can't get the NVRAM errors to happen anymore since the update. Not sure if it because that I am now using a hybrid APU GPU set up now, but the rest of the issues such as the crashing still exist.

Start by reviewing the attached nvidia-bug-report.log.gz and reproducing the issue with Memtest Vulkan alongside a game or other applications until VRAM reaches about 7.8–7.9 GB. Check whether the allocation failures and application crashes can still be reproduced after the reported update and hybrid APU setup; done means applications no longer freeze or crash when VRAM is full.
