Comment:
Hey,
awesome work so far. For my purposes I built and installed `rocm-opencl-runtime` and `rocm-hsa-ext`. I used `LD_LIBRARY_PATH=/opt/rocm/lib <cmd>` to run `clinfo`, `blender`, `hashcat` and `darktable` with a vega64.
- `blender` cycles "works"
- Too slow to be usable
- AMDGPU-PRO drivers are several times faster
- `darktable` works
- I can't make out a difference to the AMDGPU-PRO drivers
- Depending on your card you may need to set `opencl_avoid_atomics=true` in `~/.config/darktable/darktablerc`
- `hashcat --benchmark` fails with `clCreateCommandQueue(): CL_OUT_OF_HOST_MEMORY`
- might be unrelated, can't get the benchmark to run with AMDGPU-PRO, too
- maybe some algorithms work, but I didn't test. This is the case fore AMDGPU-PRO
- `clinfo` output:
