Please approve this CL. It will be submitted automatically, and its GitHub pull request will be marked as merged. Imported from GitHub PR #25011 New PR to continue the efforts started by @deven-amd in #20709 / #22669 / #24156. This PR aims to refactor StreamExecutor GPU interfaces so it can be shared among CUDA and ROCm. The PR would be the first part of a series of PRs. Based on @timshen91 's inputs, I've refactored logic in #214156 so : - only contains changes in stream_executor/.... - does not remove any stream_executor/cuda/*.h, so that things outside of stream_executor don't break. All the types and functions in the namespace cuda now alias to namespace gpu counterparts. For example, namespace cuda { using CUDADriver = gpu::GpuDriver; }. - all stream_executor/gpu/BUILD targets should be only visible to //third_party/tensorflow/stream_executor:__subpackages__. - target stream_executor/gpu:X should be only used by stream_executor/cuda:cuda_X or stream_executor/rocm:rocm_X, not cuda_Y. For example, cuda:cuda_platform should depend on cuda:cuda_driver, not gpu:gpu_driver.
