zynqmp_disp_...layer_enable(9)

💅 zynqmp_disp_blend_layer_enable — a NAME moment

okay bestie, welcome to the Kernel API Manual ✨ and today's main character is zynqmp_disp_blend_layer_enable, which — spoiler alert — is literally there to enable a layer. that's it. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

void zynqmp_disp_blend_layer_enable (struct zynqmp_disp *disp , struct
       zynqmp_disp_layer *layer );

it returns void, so like… no return value to obsess over, no error code to stress about. it just does the thing and leaves. icon behaviour, honestly. 💅

🫶 ARGUMENTS 🫶

• disp — the display controller. yes, the whole display controller. she's the boss, the main character, the one holding everything together 🌈
• layer — the layer. the one getting enabled. give her a little applause 👑

so this is the part where the manpage goes absolutely feral and links you to, like, the entire driver. no cap. here's the full cast, bestie — Kernel file ./drivers/gpu/drm/xlnx/zynqmp_disp.c and friends:

ngl, if you're poking at the blend layer, you probably also want zynqmp_disp_blend_layer_disable(9) — it's right there in the list, and it's giving "the other half of the story" 💀

🧚 a lil sign-off 🧚

and that's the page, bestie! this one lives in ./drivers/gpu/drm/xlnx and the manual's dated October 2026 — so go forth, enable that layer, and remember: you're literally the layer-enabling main character today. slay 🌸💖🍓
