Except the relay backend changes everything is reusable for Texture support in Relax. |
Motivated form the fact that textures can be allocated over a clBuffer object and the size of backing clBuffer can be computed based on hardware image pitch alignment. This optimizes the overall memory allocation on device and helps greately the models with large memory requirements. Improvised the graph memory planner to not differentiate buffer and texture storage tokens and reuse them across. The texture pool in OpenCL runtime is rebranded as memory pool that handles allocation for both buffer and image objects. NDArray to DeviceAPI interface is extended with AllocDataSpaceView and FreeDataSpaceView. These new API's acommodates accessing same physical memory as clBuffer / clImage objects.
