dce8_dmif_request_bandwidth(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

dce8_dmif_request_bandwidth — okay so this is the one that gets the dmif bandwidth, bestie ✨ (and yes it's a section 9 Kernel API Manual page, very official, very demure)

✨ SYNOPSIS

u32 dce8_dmif_request_bandwidth (struct dce8_wm_params *wm );

🫶 ARGUMENTS

  • wm — the watermark calculation data 🎀 like, that's the whole vibe, it's the struct that holds all the watermark math stuff

🎀 DESCRIPTION

So what this does 💖 it calculates the dmif bandwidth that's used for display, and it's specifically the CIK flavour of that whole situation. Not me explaining it perfectly, but here we go:

  • it's used for display watermark bandwidth calculations 🌸
  • it returns the dmif bandwidth in MBytes/s 🔥 and that's, like, the entire point

Literally that's it, it's giving "small function, big responsibility" energy, main character behaviour honestly 👑

🌈 SEE ALSO

okay so this list is iconic — it's lowkey the whole CIK/DCE8 friend group, and every single one of them is invited 🫶💖

First up, the source file:

  • Kernel file ./drivers/gpu/drm/radeon/cik.c

Then the whole squad, no cap 🔥

like, read them all, they're literally all connected, iykyk 🌈💀

okay bestie that's the page 💜 it came from ./drivers/gpu/drm/radeon, dated October 2026, and it's filed under dce8_dmif_request_bandwidth(9) in the Kernel API Manual — slay, go calculate some bandwidth, periodt 🎀🦋✨
