zynqmp_disp_layer_enable(9)

💖 zynqmp_disp_layer_enable 💖

okay so bestie, welcome to the Kernel API Manual — this is the glow-up page for zynqmp_disp_layer_enable, and honestly it's short but it matters. Let's get into it ✨

---

🌸 NAME 🌸

zynqmp_disp_layer_enable — Enable a layer. that's it, that's the whole vibe 💅

---

🎀 SYNOPSIS 🎀

void zynqmp_disp_layer_enable (struct zynqmp_disp_layer *layer );

no return value, no drama, she just does the thing 🫶

---

🦋 ARGUMENTS 🦋

• layer — The layer. like, the actual layer you're enabling. that's the one. the main character 👑

---

⭐ DESCRIPTION ⭐

So what actually happens here? This function enables the layer in the audio/video buffer manager and in the blender. both of them, together, slay 🔥

⚠️ but bestie, important: the DMA channels are not started here. nope. they get started separately by zynqmp_disp_layer_update. so don't come for this function about the DMA channels, she's not that girl 🙈
