I'm running a rig with mixed AMD Polaris and Navi GPUs in the following hardware:

PRIME Z390-P motherboard intel i3 8100 CPU 8 GB RAM Ubuntu 20.04.2 kernel 5.11.0-44-generic

Ubuntu detects all the cards:

I installed the last version (21.40.2) of amdgpu pro with the following command:

sudo amdgpu-install -y --accept-eula --usecase=rocm,lrt,opencl,openclsdk,hiplibsdk --opencl=rocr,legacy

the output of clinfo displays:

I tried installing several versions of amdgpu and I still get the same result.

In other forums they suggest to change the following file but no success after changing it:

edit:

sudo nano /etc/OpenCL/vendors/amdocl64_40000.icd

and change:

libamdocl64.so
to:

/opt/rocm/opencl/lib/libamdocl64.so

I have a HiveOS different environment and I noticed that teamredminer detects 2 different OpenCL platforms when teamredminer starts with a mixed Polaris and Navi GPU rig:
