Re: AMD OpenCL support

Show all headers | View raw

Hello,

Disclaimer: I have no AMD graphic card and have not personally tested
what is describe below

Right now with an AMD/ATI graphic card in Debian, the only OpenCL run-
time loader (ICD) present in the offical repos is the mesa one (mesa-
opencl-icd) that you have already installed.

If it not already installed, install the clinfo package and run clinfo
to have more informations about the status of your OpenCL setup.

Perhaps your claim of not having OpenCL support is erroneous and what
happens actually is you have uncomplete/unsufficent support for your
use case: a typical example is Darktable not having OpenCL image
support, this requiring more recent OpenCL implementation that the Mesa
one.

Then you would probably have to either:
- revert to use the proprietary amdgpu-pro driver (including an AMD
ICD) instead of the free amdgpu one
https://www.amd.com/en/support/kb/faq/amdgpu-installation
- or continue using the free amdgpu driver but install ROCm (AMD ICD)
https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation-Guide.html
- or continue using the free amdgpu driver but install the ICD subset
of the proprietary driver
