STRUCT XILINX_CDMA_TX_SEGMENT(9)

✨ NAME ✨

struct xilinx_cdma_tx_segment — Descriptor segment 💅

okay so this is your girl's page out of the Kernel API Manual, section 9 (the header up top is just struct xili...a_tx_segment(9) getting its whole name cut off — tragic, honestly, she deserves the full thing). Anyway. It's a descriptor segment. That's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

struct xilinx_cdma_tx_segment {
    struct xilinx_cdma_desc_hw hw;
    struct list_head node;
    dma_addr_t phys;
 };

like… three fields. That's her. Lowkey minimalist queen 👑

🎀 Members 🎀

• hw — the Hardware descriptor, aka the actual hardware-facing bit of the whole operation 🔥
• node — the Node in the descriptor segments list. she's linked in, she's got connections, main character energy fr fr ✨
• phys — the Physical address of segment. yes bestie, an actual address in physical memory, no cap 🫶

💖 SEE ALSO 💖

before you go, the kernel file for all of this lives at ./drivers/dma/xilinx/xilinx_dma.c — go read it, it's giving ✨documentation✨

and like… the whole extended friend group, okay, they all get a mention, i'm not skipping anybody 🙈 (yes this is the entire list, don't @ me):

bestie i know that's a lot of names but that's literally all of them, i counted, i'm not dropping a single one 😭 the group chat is huge and they're all iconic okay 💜

and that's the whole page!! ✨ signed off from ./drivers/dma/xilinx, dated October 2026 — mwah, stan this struct, she ate 💅🎀
