Did anybody already succeeded to make darktable running on ARM64 with OpenCL? If so, could the winning route be shared?
I installed darktable in the chrooted Linux running on my phone with the Snapdragon 870 CPU and Adreno 650 GPU. I did just a few tests, but was really surprised how fine and fast it works. Well, at least in comparison with my old PC with 6 core AMD CPU and OpenCL GPU support which I still use for darktable. But for the real live developing at least of the RAWs coming from the phone camera the OpenCL GPU support would help in terms of speed. Unfortunately I didn't manage to make OpenCL GPU support available in the chrooted system on ARM64. Only the OpenCL support for CPU, which is useless for darktable. Was anybody already more successful than me? After installing the clinfo the libOpenCL library is available and detected by darktable. But it still doesn't work: $ darktable-cltest [dt_detect_cpu_features] Not implemented for this architecture. [dt_detect_cpu_features] Please contribute a patch.

My guess is that the problem is the graphics driver which is probably missing at all as the desktop is available via vnc only. I don't have any experience in making the OpenCL working in such kind of setup. I will be glad for any kicking me in the right direction. ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org
