Use this skill when the user is doing hands-on DOCA DMA programming — bringing up a doca_dma context, configuring the single doca_dma_task_memcpy task type, sizing buffers via the doca_dma_cap_task_memcpy_* queries, setting LOCAL_READ_ONLY / LOCAL_READ_WRITE permissions on source / destination doca_mmap regions (plus doca_mmap_export_* for cross-peer copies), driving the progress engine, or debugging DOCA_ERROR_* returns. Trigger even when the user does not explicitly mention "DOCA DMA" or…
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 DMA ## Examples - **"Memcpy a host buffer to BlueField without using the CPU."** — this is in scope. Use the shipped DMA sample and `doca_dma_task_memcpy`. - **"Copy returns NOT_PERMITTED on first submit."** — check mmap permissions and `doca_dma_cap_*` before changing the task type. ## Instructions Follow Loading order below. Open the tasks companion for configure / build / run. Open the capabilities companion for the memcpy task and path-selection vs RDMA. Do not open every companion file. **Where to start:** This skill assumes DOCA is already installed and the user is doing **hands-on DMA work** on a BlueField / ConnectX / host with DOCA. 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 DMA express* on this version. If the user has not installed DOCA yet, route to `doca-setup/SKILL.md` first. If the user is not sure DMA is even the right library — the data has to traverse the network, or the flow is small messages between two processes — read the path-selection rule in ## Capabilities and modes before configuring anything. …

How to install
mdr add nvidia/skills/doca-dma@sha256:01aad66441f111fbThe line at the top of this page pins the label git:20261028.3d06e7e, 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.
