STRUCT ZYNQMP_DISP(9)

💖 NAME 💖

struct zynqmp_disp — the Display controller, bestie. That's the whole vibe. It's the struct that runs the show (literally, it's a display controller). No cap. ✨

🌸 SYNOPSIS 🌸

Okay so here's the shape of it, and yes you're gonna want to read it carefully because every field is doing its own little job:

struct zynqmp_disp {
    struct device *dev;
    struct zynqmp_dpsub *dpsub;
    void __iomem *blend;
    void __iomem *avbuf;
    struct zynqmp_disp_layer layers[ZYNQMP_DPSUB_NUM_LAYERS];
 };

That's it. That's the whole struct. Five fields, main character energy, absolutely ate. 🫶

🎀 Members 🎀

Alright bestie, field-by-field, let's get into it 💅

• dev — the Device structure. This is the device's whole identity, its little passport. 🦋
• dpsub — the Display subsystem. The bigger picture this display controller lives inside. Think of it as the group chat and this struct is one very important member.
• blend — Register I/O base address for the blender. Not a smoothie blender, babes — the register base address. 🍓
• avbuf — Register I/O base address for the audio/video buffer manager. Yes it's a mouthful. Yes it's iconic.
• layers — Layers (planes). Yep, the manpage literally says "planes" in parentheses — iykyk, they're the same thing here. 🌈

Okay so the kernel file for all this lives at ./drivers/gpu/drm/xlnx/zynqmp_disp.c, and there's an enum and a whole entourage of related functions and structs, so let me just list them all because I refuse to leave anyone out 😤

Okay that's the page!! Signing off with the boring-but-important bits: this one's from ./drivers/gpu/drm/xlnx, dated October 2026, and the page itself is struct zynqmp_disp(9). Love that for us. Byeee 💜✨
