* @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
