Arch linux is definitely not supported.

cmake version in arch repo is extra/cmake 4.2.2-2.

Building throws this error initially

Compatibility with CMake < 3.5 has been removed from CMake. Update the VERSION argument value. Or, use the ... syntax to tell CMake that the project requires at least but has been updated to work with policies introduced by or earlier. Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

updating the minimum version fails to build llvm_project

I'm also not sure if this is just the case moving forward for rocm 7+ but I'm on cachy and in the last month or so I haven't been able to run rocminfo seems related to dmabuf changes or 7+ demanding stricted checks... containers still works. that said I did let codex just have free reign so 🤷 who knows lol -- can provide gpt chat logs if further context required

I need a couple modifications for the dockerfiles I don't think we're building rocm from source like we need to but there's a few hours gone into the arch ones there if you'd like to try
