doca-gpunetio SKILL.md skillA
doca-gpunetio from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use this skill when the user is doing hands-on DOCA GPUNetIO programming — wiring a CUDA kernel on an NVIDIA GPU to a doca-eth queue via doca_gpu_eth_rxq / doca_gpu_eth_txq, standing up the per-CUDA-device doca_gpu context, designing the persistent CUDA kernel that drains the GPU-visible queue, running the dual capability check (DOCA cap-query plus cudaGetDeviceProperties), registering cudaMalloc pools via doca_buf_arr_create_*, or debugging DOCA_ERROR_* returns from the GPUNetIO API.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DOCA GPUNetIO ## Examples - **"CUDA kernel reading packets directly from the NIC."** — this is in scope. Stay on `doca_gpu_eth_rxq` / `_txq` and the persistent kernel; do not rewrite it as host-CPU Ethernet. - **"DOCA_ERROR_DRIVER on doca_gpu_create."** — check CUDA device match and dmabuf / `nvidia-peermem` registration before changing queue type. ## Instructions Follow Loading order below. Open the tasks companion for configure / build / run. Open the capabilities companion for GPU vs host path selection. Do not open every companion file. **Where to start:** This skill assumes DOCA is already installed, the CUDA toolkit is installed and matched to the DOCA install, and the user is doing **hands-on GPUNetIO work** — i.e. wiring a DOCA network queue into a CUDA kernel on an NVIDIA GPU. Open the tasks companion if the user wants to *do* something (configure / build / modify / run / test / debug); open the capabilities companion when the question is *what can GPUNetIO express* on this version + this GPU. If the user has not installed DOCA yet, route to `doca-setup/SKILL.md` first; if the user has not set up the underlying Ethernet RX/TX queues yet, that is a …

How to install
mdr add nvidia/skills/doca-gpunetio@sha256:23e637cfa132ef2dThe line at the top of this page pins the label git:20261022.a4cf47e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
