💅 NAME 💅

rte_event_dma_adapter_runtime_params — bestie, this is the runtime config glow-up container for the DMA adapter 💖

It lives in the Library Functions Manual corner of the world, page rte_event_...ime_params(3), and yes we are absolutely gonna get into it.

✨ SYNOPSIS ✨

#include <rte_event_dma_adapter.h>

🎀 Data Fields 🎀

  • uint32_t max_nb
  • uint32_t rsvd [15]

🌸 DESCRIPTION 🌸

Okay so. rte_event_dma_adapter_runtime_params is a struct holding the adapter runtime configuration parameters — that's the whole vibe, that's the whole job.

It's defined at line 198 of the file rte_event_dma_adapter.h, in case you need receipts. 🧚

👑 FIELD DOCUMENTATION 👑

💜 uint32_t max_nb

The adapter is allowed to return early once it's processed at least max_nb DMA ops. But listen — this is not a hard requirement, no cap. Because of batching, the adapter may literally process more than max_nb DMA ops. It's giving "guideline, not a limit." 🙈

The callback function you pass to rte_event_dma_adapter_create_ext() configures the adapter with a default value of max_nb.

Then rte_event_dma_adapter_runtime_params_set() lets you re-configure max_nb during runtime — but only after you've added at least one queue pair. Order matters, bestie, do not skip steps. 💅

Heads up: this is only valid for the devices without the RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_OP_FWD or RTE_EVENT_DMA_ADAPTER_CAP_INTERNAL_PORT_OP_NEW capability. If your device has those caps, this field is not the moment. 🫶

Defined at line 199 of the file rte_event_dma_adapter.h.

🌈 uint32_t rsvd[15]

Reserved fields for future expansion — aka the spare room where DPDK keeps its future plans. Don't touch, don't poke, just let it vibe. ✨
