Actual Behavior

$ sycl-ls
[opencl:cpu][opencl:0] Intel(R) OpenCL, Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz OpenCL 3.0 (Build 0) [2026.21.3.0.31_160000]

Expected Behavior

See a level zero GPU with sycl-ls

Reproduction Rate

Always reproduces - 100%

Steps to Reproduce

Is this a regression?

  • Yes, this is a regression - functionality that previously worked is now broken

Additional Notes

We have a system with an Intel(R) Core(TM) i7-8700 CPU and the integrated UHD Graphics 630 GPU. We want to use sycl and oneAPI on the GPU (for our CI system), but with sycl-ls, we couldn't see a level zero GPU.

Could you help?
