The PASID allocator is global (not per-device), so the PASID is intended to be the same for all devices. I only need to find a device for the kfd2kgd interface pointer. In a multi-GPU system it doesn't matter which one. They all share the same PASID allocator. Technically, I think different devices could use different PASIDs for the same process. But it would make the driver more complicated and there is no reason to do this. Regards, Felix
