doca-rmax
DOCA Rivermax (doca_rmax) receive streams for timing-precise media over IP (SMPTE ST 2110 video / audio, market data, scientific feeds) on a target BlueField DPU (DOCA Rivermax apps run only there), once the Rivermax libraries and license are installed; getting them is doca-setup / doca-public-knowledge-map territory. Trigger on "ST 2110 receive isn't getting frames", "sub-microsecond jitter on my media receiver", "NOT_SUPPORTED from doca_rmax_init", "no recv events after stream start", or "license check failing on a media receiver", even without naming Rivermax. Covers doca_rmax_in_stream sessions, the SDK + license precondition check, doca_rmax_get_*_supported capability queries, pairing with doca-eth queues and doca-flow steering, and DOCA_ERROR_* from Rivermax calls. Refuse and route elsewhere for programming the underlying queue (doca-eth), steering rules (doca-flow), PTP / clock sync (doca-firefly), or best-effort packet I/O.
Why this skill is useful
Adds specific commands and workflows for setting up and debugging DOCA Rivermax sessions that are not covered in public documentation.

What this skill does
DOCA Rivermax Examples "ST 2110 receive isn't getting frames." — this is in scope after Rivermax SDK + license are already present. "How do I obtain / install the Rivermax SDK and its license?" — out of scope for this skill. Say so, give no install or licensing steps, and route: DOCA packages to doca-setup/SKILL.md, the Rivermax SDK + license to the public DOCA Rivermax guide via doca-public-knowledge-map/SKILL.md. Come back here once both are present. "NOTSUPPORTED from docarmaxinit." — run the docarmaxgetsupported queries before changing stream setup. Instructions Follow Loading order below. Open the tasks companion for configure / stream / debug. Open the capabilities companion for Rivermax preconditions. Do not open every companion file. Where to start: This skill assumes DOCA is already installed on the target BlueField DPU (DOCA Rivermax apps run only on the target DPU), AND that the Rivermax libraries (doca-sdk-rmax / libdoca-sdk-rmax-dev from the DOCA repo) are installed with a valid Rivermax license present on the DPU. The agent's FIRST action on any Rivermax question is to confirm both — without the Rivermax libraries + license, doca-rmax cannot function regardless of how clean the DOCA-side code is, and this is the #1 first-app confusion (the Rivermax license, and the driver per the Rivermax SDK page, are obtained separately from 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 DOCA Rivermax express on this version + this Rivermax install. If the user has not installed DOCA yet, route to doca-setup/SKILL.md first; for the Rivermax SDK + license install itself, route to the public DOCA Rivermax guide (slug DOCA-Rivermax) via doca-public-knowledge-map/SKILL.md. …
