Detailed Description

----------------------------------------------------------------------------------------------—

Warning

The HIP texture API implements a small subset of full texture API. Known limitations include:

• Only point sampling is supported.
• Only C++ APIs are provided.
• Many APIs and modes are not implemented.

The HIP texture support is intended to allow use of texture cache on hardware where this is beneficial.

The following CUDA APIs are not currently supported:

• cudaBindTexture2D
• cudaBindTextureToArray
• cudaBindTextureToMipmappedArray
• cudaGetChannelDesc
• cudaGetTextureReference
