What's the plan here? I see that this is a draft PR, but this (using PAL vs ROCR on Windows) looks like it should be using a feature flag:

• https://github.com/ROCm/TheRock/blob/main/docs/development/flags.md
• https://github.com/ROCm/TheRock/blob/main/FLAGS.cmake

I see that this is a draft PR, but this (using PAL vs ROCR on Windows) looks like it should be using a feature flag:

This is to test ROCr backend as default at runtime. Changes here make sure components use GPU_ENABLE_PAL=0 env variable correctly to validate ROCr backend.
The feature flags mentioned by you are build flags not runtime flags.
I want to keep the current build setup (build both PAL/ROCr) unchanged, but just test the runtime behavior by setting ROCr as default backend
