Activate OpenCL for Darktable

Hello
Iam running open SUSE Tumbleweed

I have AMD Ryzen 9 3950x and AMD Sapphire RT 7900XTX graphics card.

I am runing both KDE and GNOME

I WONDER how to make Darktable use OpenCL AND How Suse use OpenCL!

Well The funktion is there but it’s greyout

The Question is how to enable OpenCL on my system??
Because my AMD RX7900XTX card does support it!

the question is whitch one works with Darktable

@Sjostrand ROCm?

https://build.opensuse.org/package/show/science:GPU:ROCm/aomp

How do you activate, so it make it run, because Darktable is not activate

@Sjostrand Add the repository temporarily and install aomp…

zypper ar -f -g -n "Science-GPU-ROCm" https://download.opensuse.org/repositories/science:/GPU:/ROCm/openSUSE_Factory/ Science-GPU-ROCm
zypper ref
zypper in aomp

**Disable**
zypper mr -d -F Science-GPU-ROCm"

is it then sudo zypper install Science-GPU-ROCm???

the opencl is still grey out after the install!! Did i miss something ?? a setup or something??

@Sjostrand so did you install aomp?

Please show the output from;

zypper se -si -r Science-GPU-ROCm

i+ | aomp | paket | 18.0.0-1.39 | x86_64 | Science-GPU-ROCm

@Sjostrand also install the following (probably need a reboot);

**Enable**
zypper mr -e -f Science-GPU-ROCm

zypper in amd-opencl rocminfo

**Disable**
zypper mr -d -F Science-GPU-ROCm

Then test Darktable, if still not working what is the output from the command rocminfo

The output

@Sjostrand So that all looks good, so nothing in darktable I assume? If so then it probably needs building to support ROCm…

Oki then i know.

Question how do i uninstall all of this now

@Sjostrand So enable the repository and check what was installed with;

**Enable**
zypper mr -e -f Science-GPU-ROCm
zypper se -si -r Science-GPU-ROCm

From that output, create a list and then zypper rm your list and then disable the repo and remove if you want).

Thanks you for the help and all

@Sjostrand So is clinfo installed? If you run that what does it say?

clinfo [ sökväg: /usr/bin/clinfo, förråd: https-download.opensuse.org-9a68c55f ]

  • clinfo [ sökväg: /usr/bin/clinfo, förråd: https-download.opensuse.org-b070b340 ]
  • clinfo [ sökväg: /usr/bin/clinfo, förråd: repo-oss ]

@Sjostrand so looks like you need to install, zypper in clinfo
