ROCm 1.9 runs OpenCL on GPU on top of mainline kfd and seems stable. However:
- CPU is not detected as a compute device (rocminfo attached)
- Performance, at least in darktable, is quite low (the "bench.SRW" benchmark
in OpenCL on GPU takes more than 3 times longer than on CPU without OpenCL).
The problem could be that memory buffers are too small, clinfo reports:
"Max memory allocation                           268435456 (256MiB)"
which seems quite small to me (?).

Are these problems a result of incorrect information in CRAT?

Best regards
