Are there plans to support Image operations? Or is this missing because of the kernel driver of 4.18?

Image support is supplied by a closed-source component of the ROCr runtime (libhsa-ext-image64.so) that is part of the hsa-ext-rocr-dev package.

Ah ok, that works. Are there plans for an Open Source implementation?

Hi @cryptomilk

Our goal for the ROCm project is to provide all of our software as open source products. That said, the HSA image extension library is (I believe) our only remaining closed source project. Getting this through our open sourcing processing has been quite a bit more effort. It's still on our list of goals, but I cannot give you a solid timeline on when it will happen.

Thanks. Is is possible to report bugs for the closed source component?
