[sycl-ls] Arrow Lake integrated gpu detected as Meteor Lake

[mateuszpn]

Describe the bug

lscpu: "Intel(R) Core(TM) Ultra 7 265"
sycl-ls: "Architecture: intel_gpu_mtl_u"

Even though intel_gpu_arl_u and intel_gpu_mtl_u are aliased to the same architecture ID (0x0000000311800400), sycl-ls should detect and print the correct specific variant based on the actual hardware, using additional device information

To reproduce

Run sycl-ls --verbose on any Arrow Lake machine and check Architecture entry of integrated gpu

Environment

• OS: [e.g Windows/Linux]
• Target device and vendor: [e.g. Intel GPU]
• DPC++ version: [e.g. commit hash or output of clang++ --version]
• Dependencies version: [e.g. the output of sycl-ls --verbose]

Additional context

No response

@mateuszpn thanks for the report. Two architecture names with the same GMDID currently can't be distinguished between each other as they technically the same architecture, this is a known limitation of design/implementation.
Tagging @gmlueck just for awareness.

Yes, MTL-U, ARL-U, and ARL-S are all the same architecture. Level Zero identifies all of these identically, so SYCL cannot distinguish them. I think we could improve the sycl-ls output, though, by printing something like:

sycl-ls: "Architecture: intel_gpu_mtl_u / intel_gpu_arl_u / intel_gpu_arl_s"

Thanks guys. If you think the improved output will be useful, I am for it. If you don't think there is any issue, I don't mind if you close it.
