doca-devemu SKILL.md skillA
doca-devemu from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nvidia/skills/doca-devemu@git:20261022.a4cf47ePins git:20261022.a4cf47e in mdr.lock. Pin the fingerprint instead.

Use this skill when the user is doing hands-on DOCA Device Emulation on a BlueField DPU — exposing a custom emulated PCIe device the host sees as a real peripheral while DPU-side code runs the backend, picking the sub-library (PCI Generic, virtio-net, virtio-fs), wiring the per-sub-library Core context plus doorbell / DMA primitives, querying `doca_devemu_*_cap_*`, or debugging DOCA_ERROR_* from a `doca_devemu_*` call. Trigger even when the user does not say "devemu" — typical implicit…
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 Device Emulation ## Examples - **"Expose a custom PCIe device from BlueField to the host."** — this is in scope. Pick PCI Generic / virtio-net / virtio-fs; do not stand up SNAP or Virtio-net Service here. - **"lspci does not show my emulated device."** — confirm the firmware emulation type and host driver before changing DPU-side code. ## Instructions Follow Loading order below. Open the tasks companion for configure / emulate / debug. Open the capabilities companion for sub-libraries and cap queries. Do not open every companion file. **Where to start:** This skill assumes DOCA is already installed on the host AND on the BlueField, the user is doing **hands-on emulated-PCIe-device work** from the DPU side (writing the backend that the host's kernel driver will talk to over the emulated PCIe surface), and the user knows which CLASS of emulated device they want to build. 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 Device Emulation express* on this DOCA version + this BlueField generation + this firmware. If the user has not …

How to install
mdr add nvidia/skills/doca-devemu@sha256:8357ad64f23034e1The 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.
