💖 rte_dma_conf(3) 💖

okay so bestie, we're looking at rte_dma_conf — it lives over in the DPDK Library Functions Manual and it's literally just a lil struct, but she's important. no cap. let's get into it 🫶

---

✨ NAME ✨

rte_dma_conf — a struct that holds the config for your DMA device, and yes she's the whole personality 💅

---

🌸 SYNOPSIS 🌸

#include <rte_dmadev.h>

🎀 Data Fields

• uint16_t nb_vchans — how many virtual DMA channels you're setting up
• uint64_t flags — the config vibe check flags

---

🦋 DETAILED DESCRIPTION 🦋

A structure used to configure a DMA device.

that's it, that's the whole serve. she's a config struct, she configures a DMA device, she knows what she is 👑

See also: rte_dma_configure — go read her too, she's the one who actually uses this struct, iykyk ✨

💜 FIELD DOCUMENTATION 💜

🌈 uint16_t nb_vchans

the number of virtual DMA channels to set up for your DMA device, periodt. 🧚

BUT — and this is the important part, don't skip it — this value cannot be greater than the max_vchans field of struct rte_dma_info, and you get that from rte_dma_info_get(). so like, ask nicely first, get your rte_dma_info, and then respect the limit. going over is giving delulu and it will not slay 😭

🌈 uint64_t flags

DMA device configuration flags, defined as RTE_DMA_CFG_FLAG_*. go check those macros for the actual menu of options 💖
