rdma-core provides the userspace layer for the Linux kernel's RDMA (Remote Direct Memory Access) drivers. It offers libraries like libibverbs and librdmacm, enabling applications to leverage RDMA capabilities for high-performance communication. The core problem addressed is the need for a standardized interface to the kernel's RDMA drivers, simplifying application development and management. It supports a wide range of RDMA drivers, including bnxt, efa, and others, and implements daemons for managing these drivers.
rdma-core offers a comprehensive set of userspace tools for managing RDMA devices, including libraries and daemons. The project supports a broad range of RDMA kernel drivers, enhancing compatibility and flexibility. It utilizes a CMake-based build system for easy compilation and deployment.
