Hello. I'm trying to get OpenCL working on Linux Ubuntu 20.04.1 LTS on my 6900XT. I've tried these combinations:
1)
ubuntu kernel 5.4.0-54
amdgpu driver 20.45-1188099 with included rocr dkms
result: GPU is detected but clinfo hangs part way through displaying the info. My opencl code hangs trying to create a context
2)
ubuntu kernel 5.4.0-54
amdgpu driver 20.45-1188099 with --no-dkms and rocm 4.0.0.40000-23 (rocm-opencl 3.6Beta-17-g875c1f8-rocm-rel-4.0-23)
result: GPU is not detected. clinfo shows the platform AMD Accelerated Parallel Processing but has 0 devices
3)
upstream kernel 5.10.0-051000
rocm 4.0.0.40000-23 (rocm-opencl 3.6Beta-17-g875c1f8-rocm-rel-4.0-23)
result: rocminfo sees the GPU fine, clinfo hangs after displaying some of the data for the GPU just like in 1)
Here's the GPU data for rocminfo:

<clinfo hangs here>Has anyone gotten OpenCL working? Am I doing something wrong? I got this card specifically for a compute research project I'm doing so any help I can get on this is appreciated. I'm happy to provide any other info I can. Thanks!
