The DMA Streaming Framework: Kernel-Level Buffer Orchestration for High-Performance AI Data Paths (opens in new tab)

arXiv:2603.10030v1 Announce Type: new Abstract: AI transport libraries move bytes efficiently, but they commonly assume that buffers are already correctly allocated, placed, shared, registered, and safe under completion and teardown pressure. This paper presents dmaplane, a Linux kernel module that makes this missing layer explicit as buffer orchestration. dmaplane exposes a stable kernel UAPI via /dev/dmaplane and composes ring-based command channels, DMA buffer lifecycle management, dma-bu...
