I have replaced my RX 570 with Vega 56. I have reinstalled drivers to use rocm ones, but clinfo still returns Number of platforms 0.
Card itself is detected (lspci | grep VGA returns one entry).
I have also AMD APP SDK 3.0 installed on this machine.
Seems to be related to clinfo crashes - libamdoclsc64.so is missing clinfo in /opt/amdgpu-pro/bin crashes on my machine for the same reason
