ROCm OpenCL with openSUSE Tumbleweed

EDIT 20200622:
With ROCm 3.5, the easiest way is to use zypper.

- Add repository:
sudo zypper addrepo --no-gpgcheck http://repo.radeon.com/rocm/zyp/zypper/ rocm
sudo zypper ref

- Install packages:
sudo zypper in rocm-opencl3.5.0 hsa-ext-rocr-dev3.5.0

- Update lib path (if necessary). ROCm 3.5 is installed under "/opt/rocm-3.5.x". Create a symbolic link "/opt/rocm -> /opt/rocm-3.5.1". Check the lib path in /etc/ld.so.conf.d and make sure these are listed

  - /opt/rocm/lib
  - /opt/rocm/lib64
  - /opt/rocm/hsa/lib
  - /opt/rocm/opencl/lib

If not, create a new file (e.g. rocm.conf) and add the above paths.  Then run "sudo ldconfig".

Run both "/usr/bin/clinfo" and "/opt/rocm/opencl/bin/clinfo" to check if OpenCL is working.


EDIT 20200110:
(0) As of 2020-01-05, running "clinfo" with openSUSE Tumbleeweed 20200103 and these  ROCm packages will cause null pointer dereference errors.
(0) Things are working again with Tumbleeweed 20200108.
(1) The user needs to be member of the "video" group.  Run this command to add yourself to the group "sudo usermod -a -G video $LOGNAME"
(2) The site now has RPM packages for openSUSE.  Go the http://repo.radeon.com/rocm/zyp/zypper/ to download the packages instead.  Also, no need to specify "--nodeps" when installing the packages

With Tumbleweed running Linux kernel 5.0, it is easy to install ROCm OpenCL with upstream kernel.

- Go to http://repo.radeon.com/rocm/zyp/zypper/ and download the latest version of following packages:

hsakmt-roct
hsa-rocr-dev
rocm-opencl
rocm-opencl-devel
rocminfo-1.0.0

(EDIT 20200126) With ROCm 3.0, you also need to install these packages (due to an issue):
comgr
rocm-smi-lib64

- Install them without checking dependencies, assuming you already have libc etc packages installed, e.g.:

sudo rpm -ivh comgr-1.6.0.121-cbb02f9-Linux.rpm hsakmt-roct-1.0.9-319-g02e2b30.x86_64.rpm hsa-rocr-dev-1.1.30100.0-local-build-ecafeba1-Linux.rpm rocm-opencl-2.0.0--8f28d95ad-Linux.rpm rocm-opencl-devel-2.0.0--8f28d95ad-Linux.rpm rocm-smi-lib64-2.2.0.8.local-build-0-a246aac.rpm rocminfo-1.0.0.0.local_build-0-a134847.rpm

- That's it! Optionally, install clinfo with zypper to check the available platforms.  Or you can just use the one installed by rocminfo (under /opt/rocm*/bin). If you have been using Mesa OpenCL, you may want to uninstall it.

This is not working.

I can't see any openCL in Blender or with hashcat.

Thanks for posting this helpful ROCm on Tumbleweed guide! It works in LibreOffice with your mentioned corrections.

I do not have AMDGPU-PRO installed. Is this required?
Any ideas.

Thank you in advance!

i also don't have amdgpu-pro. Just using the open source amdgpu.

Make sure you have amdgpu module loaded. Also, check that you have kernel-firmware-amdgpu and xf86-video-amdgpu installed.
