I was talking with SuiChi about checking this. He says that HSA_PROFILE_FULL should be set if the pointters are usable https://alt-doc-doc-test.readthedocs.io/en/latest/ROCm_API_References/ROCr-Runtime.html#group__agentinfo_1gacafd4247e2a04cbe0ac0b3998c127532. This is apparently how it's used in rocm-info https://github.com/ROCm/ROCR-Runtime/blob/master/src/core/runtime/amd_gpu_agent.cpp#L115. So you need to query agent info with the profile as an argument.
