Adreno iGPU - usable for dt and OpenCL?

Hardware
1

I see that some of the HP notebooks comes with an Adreno integrated GPU (Snapdragon CPUs). Can linux-based dt and Open CL run on those?

It seems to run on Mali w/ OpenCL. Don’t know about the exact state of Adreno Linux drivers unfortunately, and note that very few distros have good (or any) OOTB support for the Snapdragon X platform in general ATM. Looks like Ubuntu has made the best effort so far (see Index of /~platform/images/ubuntu-concept for a more recent image)…

Even if you get it to work, the benefit might be marginal

@g-man: Would you care to explain a little why that is so?

In my little insight in hardware I compare this to @Tamas_Papp’s comment in:

Perhaps Tamas can share the export results of an image with xmp processed in his laptop using -d perf with and without Opencl. This way you could judge how many seconds it helps. Ideally the xmp includes the typical modules you the OP use.

Will do, but you have to wait a bit, my main laptop’s charging USB-C connector broke, and now I am on another machine. I will definitely get back here though once it is repaired.

This. I have Iris Xe and the benefits are sometimes negligible. Plus there are some OpenCL artifacts here and there.
