Hey, looks like with the 12.9 beta AMD finally did it!
I am able to run OpenCL applications without running X server!
Just some issues I have now with ADL:
* fan speed cannot be set without running X server (temperatures can be obtained though)
* device strings cannot be obtained using ADL without X
Are there any plans to document that GPU rings feature?
Also COMPUTE variable is not working anymore and since without X obviously DISPLAY cannot be used too, there is no way to control that (currently).
