I feel like the "why" is missing. This appears to start to explain how gem->open() might be useful for the driver, but does not seem to complete explaining the connection to the driver. From the code changes, it looks like using gem->open() simplifies the code by allocating the vpu_addr in one place for all BOs. If that is the goal, I feel that it should be mentioned here.
