💅 dce_v10_0_average_bandwidth_vs_available_bandwidth(9) 💅

okay so this is a page straight out of the Kernel API Manual bestie, and tbh it's a short one but it's giving essential. buckle up 🎀

✨ NAME ✨

dce_v10_0_average_bandwidth_vs_available_bandwidth — literally the vibe check between your average bandwidth and your available bandwidth 💖

🌸 SYNOPSIS 🌸

bool dce_v10_0_average_bandwidth_vs_available_bandwidth (struct
dce10_wm_params *wm );

that's it. that's the whole flex. a bool comes back out, one struct goes in. iconic. ✨

🦋 ARGUMENTS 🦋

  • wm — the watermark calculation data 🫶 like, this is the lil bundle of info the function needs to do its math. it's a struct dce10_wm_params *, no cap.

💜 DESCRIPTION 💜

so what does it actually do? it checks whether the display's average bandwidth fits inside the display's available bandwidth (CIK). that's the whole assignment. 💅

it's used for display watermark bandwidth calculations — so it's like a supporting character in the watermark math but lowkey important.

and the return value? super simple bestie:

  • returns true if the display fits ✅ slay
  • returns false if it does not ❌ not slay

periodt. no extra params, no side quests, just a yes/no on whether the bandwidth situation is gonna work out. 🧚

🔥 SEE ALSO 🔥

and the friend group (aka the related manpages, all of them, in order, no skips 💖):

quick reminder bestie: this is a bool function, so like… don't go looking for an error number. you get true or false and that's the whole tea. 🍓

and that's the page!! 🌈 source path ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — mwah, go read the other bandwidth manpages, ily, bye 💋👑
