Hi . Nirmoy

If you let continue to unpin. this will  allways test a same va for gtt 

I think we should  rafresh calculate  the value n 

Right, I guess then the test should only run till gart size.

When gart size is < gtt size this test will fail with
-ENOMEM as we are not freeing gtt bo after each move test.
This is generally not an issue when gart size >= gtt size.
