STRUCT XILINX_AXIDMA_TX_SEGMENT(9)

💅 struct xilinx_axidma_tx_segment(9) — from the Kernel API Manual, bestie ✨

okay so picture this: we're in the Kernel API Manual and this is the page for struct xilinx_axidma_tx_segment, aka the actual descriptor segment. she's little, she's important, she holds a hardware descriptor and she's in a list. main character energy fr fr 🎀

🌸 NAME 🌸

struct xilinx_axidma_tx_segment — Descriptor segment. that's it, that's her. one segment, doing segment things. 💖

✨ SYNOPSIS ✨

here's the whole vibe, exactly as written, no cap:

struct xilinx_axidma_tx_segment {
    struct xilinx_axidma_desc_hw hw;
    struct list_head node;
    dma_addr_t phys;
 };

🦋 MEMBERS 🦋

three members, three little besties, let me introduce them 🫶

• hw — Hardware descriptor. the actual hardware-y part, she's the whole point lowkey 👑
• node — Node in the descriptor segments list. this is how she links up with all her other segment girlies 💅
• phys — Physical address of segment. yes it's a dma_addr_t, yes it's the physical address, and yes we stan a typesafe address, periodt ⭐

🔥 SEE ALSO 🔥

okay so there are a LOT of friends in this extended universe, and we are NOT skipping a single one — every name below, exactly as it appears, because they all ate and they all deserve their flowers 🌈

and that's the page!! 🧚 from ./drivers/dma/xilinx, dated October 2026, and the footer still calls her struct xili...a_tx_segment(9) because the truncation is iconic and we respect it 💀💜 mwah, go read the other 60-something pages, ily, bye 🍓
