doca-rmax

separate

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.

When to use

• 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
• license check failing on a media receiver
• doca_rmax_in_stream sessions
• SDK + license precondition check
• doca_rmax_get_*_supported capability queries

When not to use

• programming the underlying queue (doca-eth)
• steering rules (doca-flow)
• PTP / clock sync (doca-firefly)
• best-effort packet I/O
• Rivermax SDK install
• Rivermax license acquisition
