🌸 dce_v8_0_data_return_bandwidth(9) — Kernel API Manual 🌸

okay so bestie, welcome to the section 9 glow-up of dce_v8_0_data_return_bandwidth ✨ this is a Kernel API Manual page and it's literally about figuring out how much data return bandwidth your display is working with. tiny page, immaculate vibes, let's get into it 💅

🎀 NAME 🎀

dce_v8_0_data_return_bandwidth — get the data return bandwidth 👑

Like, that's the whole job. It gets the bandwidth. It returns it. Main character behavior fr fr.

✨ SYNOPSIS ✨

u32 dce_v8_0_data_return_bandwidth (struct dce8_wm_params *wm );

That's the signature, keep it exactly like that, no cap 🫶 she takes one pointer and hands you back a u32.

🦋 ARGUMENTS 🦋

  • wm — watermark calculation data 💧 like, this is the struct carrying all the watermark math ingredients, and you're passing it in so the function has something to chew on.

💖 DESCRIPTION 💖

So what does she actually do? She calculates the data return bandwidth used for display (CIK) 🔥 that's the whole assignment.

This one's used for display watermark bandwidth calculations, so she's part of the watermark pipeline — iykyk 🌈

And the return value? She returns the data return bandwidth in MBytes/s ⭐ that's megabytes per second, bestie, don't forget the units.

👀 SEE ALSO 👀

The kernel file lives at ./drivers/gpu/drm/amd/amdgpu/dce_v8_0.c — that's her home address 🏠

And here's the whole friend group, all the section 9 besties she hangs out with:

periodt. that's the entire guest list 💀

ngl bestie, everything above is the whole page — every argument, every unit, every single SEE ALSO reference is right here. nothing skipped, nothing invented 🧚

and that's a wrap! 🎀 this icon came to you from the source ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — go drink some water and go read dce_v8_0.c 💜🫶
