Hello Murray, OpenCL is currently not exposed by the nv50 driver — the one used by your 9400 GT as well as the 9800 GT when using Nouveau. It is a work-in-progress though and I could give you some instructions on how to get it going, but bear in mind that you will need to build a custom version of Mesa and it is still failing some of the basic OpenCL-CTS tests.
OpenCL status can now be followed via mesamatrix.net, though you will need to scroll down past OpenGL and Vulkan to see it: https://mesamatrix.net/#OpenCL. As you can see there, nv50 is not listed as supported. Best, Pierre On 2021-07-30 — 17:43, Murray Van Luyn wrote: > Hi, > > Prolly not the most on-topic post, so I'll keep it brief.
