   After a bit of research it seems that no implementation in Mesa actually 
respects pQueuePriorities; therefore I have reverted that part of the change. 
We might want to revisit this in the future.
   
   As for VkQueueGlobalPriorityEXT, it's mostly meant for real-time use cases 
that requires GPU preemption, e.g. compositors, and requires process privileges 
for any higher-than-normal priority settings. Since most TVM workload is 
non-interactive, it's better to just not use it, or even if we use it, we would 
set the priority to LOW.
   
   Also see the reply to the [code 
comment](https://github.com/apache/incubator-tvm/pull/6662#discussion_r502926030).
