So it means amdvlk already supports ray tracing?

I think it's just the closed source Vulkan driver for now.

I see, thanks. Just curious, why does AMD still have a split between open and closed compilers for amvdlk / amdvlk-pro?

AFAIK it was more work to cut the Windows performance tweaks from our in-house shader compiler (which are felt to be a source of competitive advantage) than to patch in the already-open LLVM-based compiler.

The open source AMD Vulkan driver is still maintained as a closed-source cross-OS code base and sanitized for each release... and apparently sanitizing the compiler code wasn't a good fit with automation and so would eat a lot of compiler engineer time for each new release.

Another factor was that at the time we were looking hard at replacing the in-house shader compiler with an llvm-based one for all OSes, so this was a good way for the closed-source teams to get some familiarity with the llvm compiler. Not sure what current status of that is though.
