Just out of curiosity, will this also work with desktop GPUs on x64 architecture in the future? Any possibility? |
It may run on some Intel GPUs, but it's not optimized for them. For desktop GPUs, there are already plenty of well-optimized backends available |

This PR adds support for the OpenCL backend. Currently, this support is limited to Adreno GPUs. With the current ggml submodule, only Adreno 7xx series GPUs are supported. However, a previous PR that synced ggml will also enable support for Adreno 6xx series GPUs.
I'll update Local-Diffusion to use the latest ggml-opencl for those who don't want to bother with compiling and using adb
EDIT: kinda works with this patch ggml-org/ggml@8606b82. Performance is 2× slower than the CPU. I don't think it's worth adding this backend at the moment
