Saying that, I do agree that vendors should enable support in customer GPUs and feel that their focus on protecting server sales is going to turn out misguided in the long term. Intel especially disappointed in this area, as they in the past did allow such functionality on their GPUs, but have recently removed that.
AMDs mainstream CPUs supporting server features such as ECC also have proven that such restrictions aren't necessary, and allowing this type of capability on mainstream platforms in no way harms enterprise sales.
That being said, any effort focused on GPU virtualization or drivers impresses me immensly and I very much appreciate the work done on VirGL.
