 connor (burnt/out) (UTC-8) | Got the majority of redists in https://github.com/nixos-cuda/cuda-legacy/pull/1; still need to verify stuff builds and add more redists to the older package sets
Everything being as-is is nice, I don’t have to care nsight_systems uses an old version of Qt with known vulnerabilities | 01:28:19 |
 hacker1024 | If anyone happens to be using datacenter drivers, be aware the the GSP firmware is not loading. This might lead to unexpected performance problems.

 Daniel Fahey | Anyone with a phat rig (16+ cores 100+ GB RAM) able to test building this fix? https://github.com/NixOS/nixpkgs/pull/455364 | 20:57:01 |
 Gaétan Lepage | Yes | 22:26:21 |
| Gaétan Lepage | python313Packages.vllm built successfully with cudaSupport! | 23:13:09 |
| Gaétan Lepage | I started an extensive nixpkgs-review with cudaSupport = true but it will take a while to complete. | 23:15:33 |

| Daniel Fahey | Thanks! I think it's ready to merge then, I've marked the PR ready to review | 12:43:44 |
| Gaétan Lepage | I was away from my computer, but I managed to run nixpkgs-review successfully. Good job Daniel Fahey!
I've seen that happysalade merged the PR. | 18:17:00 |
| Daniel Fahey | No problem, thanks for running nixpkgs-review and good to know TorchRL and KServe are OK | 18:24:42 |
| Daniel Fahey | btw I'm having a quick look into https://hydra.nixos-cuda.org/build/1784 | 18:29:42 |
| Gaétan Lepage | Oh good! | 18:48:06 |
 asa | is there a reason packages like tensorrt require a manual installation and then running nix-store --add-fixed sha256 TensorRT-10.9.0.34.Linux.x86_64-gnu.cuda-12.8.tar.gz to put them in the nix store? | 21:41:07 |
| asa | as opposed to directly downloading the tarball (eg. from https://developer.nvidia.com/downloads/compute/machine-learning/tensorrt/10.9.0/tars/TensorRT-10.9.0.34.Linux.x86_64-gnu.cuda-12.8.tar.gz) under the relevant license | 21:41:45 |
| Daniel Fahey | IDK I'm just guessing licensing? | 21:42:17 |
| asa | yeah it seems like a weird "nvidia requires you to sign in and agree to their eula" thing | 21:42:41 |
| asa | but i don't think(?) it violates their license if private groups that already have agreed to the eula override the tensorrt package to fetch from the url anyway | 21:43:18 |
| Daniel Fahey | They relaxed a lot of their law fare bullshit recently | 21:43:38 |
| asa | a related question - it appears the tensorrt in nixpkgs is labelled only for x86_64 (possibly because nvidia only offers generic linux binaries for x64), but they offer a tarball for ubuntu 24, would i just be able to override the source for the arm build and let patchelf handle the rest? | 21:44:53 |

| Daniel Fahey | Try it out, looks like it needs a new maintainer anyway. I nominate you https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/python-modules/tensorrt/default.nix | 21:46:58 |
| asa | sounds good, perhaps i'll try to figure out how to use nixpkgs' cuda infra first | 21:49:07 |
