STRUCT MSGDMA_SW_DESC(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct msgdma_sw_desc(9) — like, the kernel API manual but make it make sense 🎀

okay so bestie, welcome to the glow-up of the struct msgdma_sw_desc page — it lives in the Kernel API Manual and honestly it's giving "small struct, big responsibilities" energy ✨

🌸 NAME 🌸

struct msgdma_sw_desc — it implements a sw descriptor, no cap 🫶

✨ SYNOPSIS ✨

here's the whole vibe, character for character, don't touch it:

struct msgdma_sw_desc {
    struct dma_async_tx_descriptor async_tx;
    struct msgdma_extended_desc hw_desc;
    struct list_head node;
    struct list_head tx_list;
 };

like… four members and every single one of them is carrying the team 😭👑

🦋 Members 🦋

  • async_tx — this is the support for the async_tx api. the icon that it is 💖
  • hw_desc — the associated HW descriptor. your hardware bestie fr fr 🔥
  • node — the node you use to move from the free list to the tx list. it literally commutes, main character energy 🌈
  • tx_list — the transmit list node. it's on the list, it's thriving 💜
