Description

refs #3211

Previous driver didn't work with 6.8.0-147-generic. This driver should.

Codex computed the SHA-256 from NVIDIA’s official installer at url, and ran sha256sum on it to get a7781b2e1c2d65c6580914c76e79ed454d02945df84711c033070a092a9ab49d.

- Line 113: suggestion: Add the checksum provenance to the PR description. The
matrix contract requires the owner to state how `DRIVER_SHA256` was obtained and
asks reviewers to recompute it.

The PR currently states only the kernel compatibility motivation.
([github.com](https://github.com/NVIDIA/cuda-python/pull/3295)) Record the exact
installer URL and the command used to calculate the hash. The hash itself
matches NVIDIA's published checksum, so do not change the value.

Summary by CodeRabbit

• Chores
  • Updated the NVIDIA driver version used in the Linux CUDA 13.4.2 test configuration.

The Linux amd64 Python 3.12 CUDA 13.4.2 nightly-numba-cuda matrix row now uses driver 580.126.18 and its updated installer SHA-256.

Changes: CUDA test matrix

Layer / File(s)	Summary
Update CUDA driver matrix entry ci/test-matrix.yml	The CUDA 13.4.2 nightly-numba-cuda row changes its driver from 580.65.06 to 580.126.18 and updates the installer SHA-256.

Priority: Low

Change: Bug fix

Merge Risk: Minimal · up to f6db7

The driver update has no established runtime or deployment risk; checksum provenance remains an unverified documentation concern.

- [ ] Autofix · Keep fixing CodeRabbit findings and required CI, and resolving merge conflicts

codex GPT-6.1-Sol ultra:

No actionable findings in PR #3295 at f6db77f.

• The driver pin update preserves R580 compatibility coverage and flows correctly through the installer.
• I independently recomputed the installer’s SHA-256; it matches the committed value and NVIDIA’s published checksum.
• Remaining validation gap: successful installation on kernel 6.8.0-147-generic still needs a live nightly run. The passing PR checks do not exercise that path.
