STRUCT XILINX_PL_DMA_VARIANT(9)

okay so we're deep in the Kernel API Manual rn and today's main character is struct xilinx_pl_dma_variant — a super tiny struct with big "i'm just here to hold one (1) fact" energy. bestie it is literally four lines of C. let's get into it 💅

---

🌸 NAME 🌸

struct xilinx_pl_dma_variant — the PL DMA PCIe variant info holder 🎀

Like, that's the whole job. It tells you about the variant. Slay.

---

✨ SYNOPSIS ✨

okay here's the whole thing, and yes this is genuinely all of it:

struct xilinx_pl_dma_variant {
    enum xilinx_pl_dma_version version;
};

look at her. one member. immaculate minimalism. 🔥

---

💖 Members 💖

• version — the DMA version, bestie. that's it, that's the member. it's an enum xilinx_pl_dma_version, and it is highkey carrying this entire struct on its back 🫶

ngl the tiny ones are always the most confident. one field, zero notes, no cap.

🔍 SEE ALSO 🔍

if you wanna go be nosy (and you should, that's where the actual story lives 👀), go peek at:

• the kernel file ./drivers/pci/controller/pcie-xilinx-dma-pl.c 🦋
• struct pl_dma_pcie(9) — the big sibling
• xilinx_pl_dma_pcie_init_irq_domain(9) — the irq domain one, iconic behaviour

okay that's the whole vibe check, we ate and left no crumbs 🍓

signing off from ./drivers/pci/controller — dated October 2026 — and the footer's whole entire name is struct xilin..._dma_variant(9) 💜 (yes they truncated it in the footer too, we don't question the vision) 💫
