zynqmp_disp_setup_clock(9)

💅 zynqmp_disp_setup_clock(9) 💅

okay so welcome to the Kernel API Manual, bestie — this one's a little function with main character energy: it sets up the pixel clock rate for the display controller. that's it, that's the vibe 🎀

---

✨ NAME ✨

zynqmp_disp_setup_clock — configure the display controller pixel clock rate 🕰️

like, literally it configures the pixel clock rate of the display controller. no cap.

---

🌸 SYNOPSIS 🌸

int zynqmp_disp_setup_clock (struct zynqmp_disp *disp , unsigned long mode_clock );

that's the whole signature, copy it exactly, don't be weird about it 🫶

---

🦋 ARGUMENTS 🦋

• disp — the display controller. your main character struct 💖
• mode_clock — the pixel clock rate, in Hz. yes, Hz, not MHz, not vibes, Hz 🔥

---

⭐ RETURN ⭐

0 on success, or a negative error clock otherwise 😭

that's exactly how the page says it — "a negative error clock" — so that's what i'm telling you, word for word. don't come for me, i just work here 💀
