💖 dce_v8_0_dmif_request_bandwidth(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this is the page for dce_v8_0_dmif_request_bandwidth(9), and it's literally about getting the dmif bandwidth. lowkey niche, highkey iconic. 🫶

🌸 NAME 🌸

dce_v8_0_dmif_request_bandwidth — get the dmif bandwidth 💅

🦋 SYNOPSIS 🦋

u32 dce_v8_0_dmif_request_bandwidth (struct dce8_wm_params *wm );

No cap, that's the whole call. 💖

🎀 ARGUMENTS 🎀

• wm — watermark calculation data. That's the vibe: it's the watermark math basket you're handing over. 🧺✨

💜 DESCRIPTION 💜

So the function Calculate the dmif bandwidth used for display (CIK). Not me being obsessed with display bandwidth math, but here we are. 😭

It's Used for display watermark bandwidth calculations. And then — the main character moment — it Returns the dmif bandwidth in MBytes/s. periodt. 🔥
