dce8_latency_watermark(9)

dce8_latency_watermark(9) — Kernel API Manual ✨

okay bestie, welcome to the dce8_latency_watermark page 💅 this one lives in the Kernel API Manual and it’s giving “small helper, big display-energy” vibes 🫶

🌸 NAME 🌸

dce8_latency_watermark — get the latency watermark 💖

✨ SYNOPSIS ✨

u32 dce8_latency_watermark (struct dce8_wm_params *wm );

🎀 ARGUMENTS 🎀

• wm — watermark calculation data. That’s the whole assignment bestie: it’s the data used for the watermark calculation 🍓

🦋 DESCRIPTION 🦋

Calculate the latency watermark (CIK) ✨. It’s used for display watermark bandwidth calculations, and it returns the latency watermark in ns. No cap, that’s the whole function and it ate 💅
