💖 rte_dma_inter_domain_param 💖

okay bestie, so this is a page from the Library Functions Manual — lowercase girlies call it rte_dma_in...main_param(3). It's a struct. A whole little struct. And we're gonna get to know her, because she's the glow-up you need if you're shipping DMA across processes or operating systems. 🦋

✨ NAME ✨

rte_dma_inter_domain_param — no cap, that's the whole name, that's the whole vibe.

🌸 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]

🌈 Detailed Description 🌈

bestie, this is the glow-up struct that holds all the parameters for inter-process or inter-OS DMA transfers. ✨ literally the plug for cross-domain movement.

⚠️ Warning — EXPERIMENTAL: this API may change without prior notice. it's giving undefined situationship, not committed relationship. guard your heart (and your build). 💀

So here's the tea: this structure defines the params you need to do DMA transfers across different domains — like between processes, or between operating systems. it carries the domain type plus the handler identifiers for both the source and the destination domains. main character energy for sure. 👑

When the domain type is RTE_DMA_INTER_DOMAIN_NONE, both source and destination handlers are invalid, and the DMA operation is confined within the local process. staying in your lane, staying cozy, staying home. 🏠

But for DMA transfers going from the local process or OS domain to another process or OS domain, valid source and destination handlers must be provided. no ghosting your handlers, they have to actually show up. 💅

🍓 uint16_t src_handler

Source domain handler identifier. the origin story. 🌱

🦋 uint16_t dst_handler

Destination domain handler identifier. where we're headed, the final boss location. 🗺️

⭐ uint64_t reserved[2]

Reserved for future fields. it's saving seats at the table for future eras, we love forward planning. not me being obsessed with a placeholder array. 🙈
