STRUCT XILINX_DMA_TX_DESCRIPTOR(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, this is struct xilinx_dma_tx_descriptor(9) from the Kernel API Manual, and she is literally the per-transaction main character 💅✨

💖 NAME 💖

struct xilinx_dma_tx_descriptor — Per Transaction structure. That's the whole assignment, no cap.

✨ SYNOPSIS ✨

Here's the struct in all her glory — copy it exactly, don't freestyle the fields:

struct xilinx_dma_tx_descriptor {
    struct dma_async_tx_descriptor async_tx;
    struct list_head segments;
    struct list_head node;
    bool cyclic;
    bool err;
    u32 residue;
};

🌸 Members 🌸

okay so the fields, one by one:

  • async_tx — Async transaction descriptor. The async-tx icon herself.
  • segments — TX segments list. All the TX segments, chillin' in a list.
  • node — Node in the channel descriptors list. Her little spot in the channel descriptor lineup.
  • cyclic — Check for cyclic transfers. Cyclic-transfer check energy.
  • err — Whether the descriptor has an error. The error flag, periodt.
  • residue — Residue of the completed descriptor. The completed-descriptor residue, exactly.
