It was noted that we made the same mistake for VM_ID as for object handles, whereby we ensured that we only allocated a single handle for one ppgtt. This has the unfortunate consequence for userspace that they need to reference count the handles to avoid destroying an active ID. If we allow multiple handles to the same ppgtt, userspace can freely unreference any handle they own without fear of destroying the same handle in use elsewhere.
