Description
### Which component impacted?
_No response_
### Is it regression? Good in old configuration?
None
### What happened?
When we want to dump a surface from GPU to CPU side, the vaGetImage()/vaPutImage() pair performance is lower than then the manner using vaDeriveImage().
So far as we know, the vaGetImage()/vaPutImage() pair should be the first choice for downloading and uploading the surface from CPU to GPU side, especially on the DGPU mode. And when we use vaGetImage()/vaPutImage() to implement surface mapping, we can provide the direction and read only, write only hint to optimize the mapping performance.
But currently, the vaGetImage()/vaPutImage() performance is about 20% lower than the vaDeriveImage() when mapping the same surface.
On TGL+ platform.
