At image bind time, if an image's addresses can be placed into the aux-map without causing conflicts with a pre-existing mapping, do so. The code aux management code in the binding function operates on a per-plane basis. So, use the per-plane CCS memory range from the image rather than the CCS memory region for the entire BO. Another way to avoid aux-map conflicts is to rely solely on having a dedicated allocation for an image. Unfortunately, not all workloads change their behavior when drivers report a preference for dedicated allocations. In particular, 3DMark Wild Life Extreme does not make more dedicated allocations and such a solution was measured to perform ~16% worse than this solution. With this solution, I did not measure a loss of CCS on that benchmark.
