rte_dma_in...main_param(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💖 NAME 💖

rte_dma_inter_domain_param — bestie, this is the page for that struct, and yes it's from the rte_dma_in...main_param(3) page in the Library Functions Manual, so you're in exactly the right place 🫶

✨ SYNOPSIS ✨

#include <rte_dmadev.h>

🎀 Data Fields 🎀

  • enum rte_dma_inter_domain_type type
  • uint16_t src_handler
  • uint16_t dst_handler
  • uint64_t reserved [2]

🌸 DESCRIPTION 🌸

Okay so this struct is literally the param bundle for inter-process or inter-OS DMA transfers — like when your DMA needs to travel between domains and not just vibe in its own lane 💅

⚠️ Warning: EXPERIMENTAL — this API may change without prior notice. So don't get too attached, she's still figuring herself out 😭

This structure defines all the parameters you need to pull off DMA transfers across different domains, like between processes or between operating systems. It's giving main character energy: it carries the domain type plus the handler identifiers for both the source domain and the destination domain 🔥

When domain type is RTE_DMA_INTER_DOMAIN_NONE, both the source and destination handlers are invalid, and the DMA operation stays confined within the local process. No cap, it's a homebody 🏠

For DMA transfers going from the local process or OS domain out to another process or OS domain, you must provide valid source and destination handlers. Both of them. Periodt ✨

🌈 uint16_t src_handler

Source domain handler identifier — the little name tag for where your data is coming from 🎀

Definition at line 637 of file rte_dmadev.h.

🌈 uint16_t dst_handler

Destination domain handler identifier — the name tag for where it's going 🛬

Definition at line 639 of file rte_dmadev.h.

🌈 uint64_t reserved[2]

Reserved for future fields 👀 (the struct's way of saving a seat for someone who hasn't shown up yet)
