Description js333031 2024-12-16 15:35:35 UTC 
I would like to use my A770 Intel GPU card for media processing and AI tasks within Digikam. OpenCL hardware detection finds iGPU on my Intel 8700 i7 CPU but my system also had an A770 

"Help->Components Information->OpenCV Configuration" is pasted below. 

OpenCL Device" data sees the iGPU (UHD Graphics 630) but not the A770.
OpenCL platform->Intel OpenCL Graphics sees the A770. 
Task Manager shows iGPU activity but no usage on A770. I can use A770 with other apps though.

Comment 1 js333031 2024-12-16 16:37:54 UTC 
Some experimentation results:
1. Disable iGPU in Windows Device Manager and connect HDMI cable to A770 allows Digikam to select the A770. I don't know how to confirm that accelerated compute using OpenCL+A770 is in effect after doing this though
2. After doing above, re-enable iGPU while the HDMI cable is still connected to the A770. Digikam OpenCV configuration shows A770 still

I restarted Digikam before each of the tests above.
Comment 2 js333031 2024-12-16 16:39:17 UTC 
So I guess the request is that if dGPU is not the primary system device, allow digikam to allow user to select the specific OpenCL/dGPU device
