rosidl_buffer_backends

Vendor-specific storage backends for rosidl::Buffer, enabling ROS 2 publishers and subscribers to share accelerator-accessible memory without copying when supported, with automatic fallback to the default CPU path.

Packages

cuda_buffer_backend – CUDA buffer backend packages for zero-copy GPU memory sharing using CUDA VMM IPC.
qc_buffer_backend – Qualcomm buffer backend packages for HTP-CPU zero-copy sharing using dma-buf memory.
libtorch_vendor – Vendor package that downloads and installs the pre-built LibTorch C++ distribution.
tensor_msgs – DLPack-aligned ExperimentalTensor.msg definition.
torch_conversions – Header-only helper library that converts between tensor_msgs/ExperimentalTensor and at::Tensor and exposes DLPack import / export. Replaces the older torch_buffer_backend plugin approach with a plain message + bridge library that rides on top of whichever rosidl::Buffer backend is registered (CUDA when available, CPU otherwise).

rosidl_buffer_backends

Vendor-specific storage backends for rosidl::Buffer, enabling ROS 2 publishers and subscribers to share accelerator-accessible memory without copying when supported, with automatic fallback to the default CPU path.

Packages

cuda_buffer_backend – CUDA buffer backend packages for zero-copy GPU memory sharing using CUDA VMM IPC.
qc_buffer_backend – Qualcomm buffer backend packages for HTP-CPU zero-copy sharing using dma-buf memory.
libtorch_vendor – Vendor package that downloads and installs the pre-built LibTorch C++ distribution.
tensor_msgs – DLPack-aligned ExperimentalTensor.msg definition.
torch_conversions – Header-only helper library that converts between tensor_msgs/ExperimentalTensor and at::Tensor and exposes DLPack import / export. Replaces the older torch_buffer_backend plugin approach with a plain message + bridge library that rides on top of whichever rosidl::Buffer backend is registered (CUDA when available, CPU otherwise).

rosidl_buffer_backends

Vendor-specific storage backends for rosidl::Buffer, enabling ROS 2 publishers and subscribers to share accelerator-accessible memory without copying when supported, with automatic fallback to the default CPU path.

Packages

cuda_buffer_backend – CUDA buffer backend packages for zero-copy GPU memory sharing using CUDA VMM IPC.
qc_buffer_backend – Qualcomm buffer backend packages for HTP-CPU zero-copy sharing using dma-buf memory.
libtorch_vendor – Vendor package that downloads and installs the pre-built LibTorch C++ distribution.
tensor_msgs – DLPack-aligned ExperimentalTensor.msg definition.
torch_conversions – Header-only helper library that converts between tensor_msgs/ExperimentalTensor and at::Tensor and exposes DLPack import / export. Replaces the older torch_buffer_backend plugin approach with a plain message + bridge library that rides on top of whichever rosidl::Buffer backend is registered (CUDA when available, CPU otherwise).
