zynqmp_dp_max_rate(9)

✨ zynqmp_dp_max_rate(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a little function from the Xilinx ZynqMP DisplayPort corner of the kernel, and honestly? she's a math girlie. let's get into it 🎀

---

🌸 NAME 🌸

zynqmp_dp_max_rate — calculate and return available max pixel clock 💅

like, she does the math and hands you back the biggest pixel clock your link can handle. no cap.

---

🦋 SYNOPSIS 🦋

int zynqmp_dp_max_rate (int link_rate , u8 lane_num , u8 bpp );

three args in, one int out. she's lowkey efficient like that ✨

---

💜 ARGUMENTS 💜

• link_rate — the link rate, measured in Kilo-bytes / sec. yes bb, kilobytes per second, that's the unit, write it down 📝
• lane_num — number of lanes. how many little highways we're working with 🛣️
• bpp — bits per pixel. the color depth vibe check 🌈

---

👑 RETURN 👑

max pixel clock (KHz) supported by the current link config 🫶

that's it, that's the whole return. she gives you the ceiling and you go live your life 💫

ngl this is the kind of function that just answers the question and dips. iconic.
