zynqmp_disp_...global_alpha(9)

✨ zynqmp_disp_...global_alpha(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a function page, and it's short and sweet — we're talking global alpha blending on the ZynqMP display controller. let's get into it 🎀

---

🌸 NAME 🌸

zynqmp_disp_blend_set_global_alpha — configure global alpha blending ✨ literally what it says on the tin, no cap.

---

🦋 SYNOPSIS 🦋

void zynqmp_disp_blend_set_global_alpha (struct zynqmp_disp *disp , bool
enable , u32 alpha );

that's it. that's the whole signature. returns nothing (void), takes three things, done. ate and left no crumbs 🔥

---

💖 ARGUMENTS 💖

• disp — the display controller, aka the main character of this whole operation 👑
• enable — true to enable global alpha blending. flip it on, babe 🫶
• alpha — the global alpha value. heads up though: it's ignored if enabled is false, so don't come crying if you set it while blending is off 😭
