doca-flow-dpa-provider
Use this skill when the user is doing hands-on DOCA Flow DPA Provider work — exporting a `doca-flow` pipe or external resource (index-selector/memory) into BlueField DPA address space so a DPACC-built kernel can read counters, mutate hash-pipe entries, and update/read memory or index-selector resources inline with Flow. Covers per-port `doca_flow_dpa_ctx`, three queue types (general/resources-write/resources-read), the order-sensitive export handshake (`_export_prepare` → add entries → `_export` → `_get_device_addr`), and DPA-side device API. Trigger even when the user does not say "DOCA Flow DPA Provider" — implicit phrasings include "DPA kernel never sees entries in the exported pipe", "BAD_STATE from `_pipe_export`", "how do I disable a hash entry from a DPA kernel", "DPA memory read returns no value", or "DPA-side post keeps returning AGAIN". Refuse and route elsewhere for `doca-flow` pipe construction, generic host-side DPA (`doca-dpa`), or DPA-side kernel-writing — those belong to other skills.

What this skill does
DOCA Flow DPA Provider Where to start: This skill assumes DOCA is already installed, the user has a BlueField with a DPA processor that the host can see through DOCA, the user already programs DOCA Flow from the host (doca-flow) and already runs DPA kernels from the host (doca-dpa / DPACC compiler), and the user is doing hands-on DPA Flow Provider work — i.e. using doca-flow-dpa-provider to export an existing DOCA Flow pipe or external resource into the DPA address space so a DPA kernel can manipulate it inline. Open TASKS.md if the user wants to do something (configure / build / modify / run / test / debug); open CAPABILITIES.md when the question is what can the provider express on this version + this BlueField generation. If the user has not installed DOCA yet, route to doca-setup first; if the user has not stood up a host-side Flow pipe yet, route to doca-flow first; if the user has not stood up host-side DPA execution yet, route to doca-dpa first. Example questions this skill answers well The CLASSES of DPA Flow Provider questions this skill is built to answer, each with one worked example. The agent should treat the class as the load-bearing piece — the worked example is a single instance. "Is this library even the right tool for what I want?" — worked example: "I want my DOCA Flow pipe to be readable from a DPA kernel, OR I want to do something fancier than the host-side doca-flow API exposes". Answered by the decision rule in CAPABILITIES.md ## Capabilities and modes ("three-program model: when this library is the right surface vs pure host-side Flow vs pure DPA"). Most first-time askers do NOT need this library; the skill's first job is to confirm they do. "How do I export an existing DOCA Flow pipe to the DPA side?" — worked example: "I have a Flow pipe with a counter on every entry; I want a DPA kernel to read those counters inline and decide what to do next". …
