💅 dce_v10_0_dm...st_bandwidth(9) — bestie's guide to the Kernel API Manual ✨

okay so real talk, we're in the Kernel API Manual today and the page name is literally dce_v10_0_dm...st_bandwidth(9) — yes the middle is all squished with dots, that's not me being lazy, that's the actual header, iykyk 😭. The function we're actually fangirling over is dce_v10_0_dmif_request_bandwidth, and she is a whole vibe. let's get into it 🎀

✨ NAME ✨

dce_v10_0_dmif_request_bandwidth — get the dmif bandwidth 🫶

like, that's her job. that's what she does. she gets the dmif bandwidth and she does it flawlessly.

🌸 SYNOPSIS 🌸

u32 dce_v10_0_dmif_request_bandwidth (struct dce10_wm_params *wm );

okay copy that exactly pls, spaces and all — she's particular about her signature 💅. she returns a u32 and takes one pointer, that's it, low maintenance queen 👑.

🦋 ARGUMENTS 🦋

  • wm — watermark calculation data. that's the whole tea 🍓. it's a struct dce10_wm_params * and it's holding all the watermark calculation data so she can do her math. give her the data and she'll give you the bandwidth, no cap.

💖 DESCRIPTION 💖

okay so the actual moment you've been waiting for: she calculates the dmif bandwidth used for display (CIK). that's the whole assignment, she ate and left no crumbs ✨.

and what's it for? it's used for display watermark bandwidth calculations — so like, she's part of the bigger watermark pipeline, doing her little part, main character energy fr fr 🌈.

and the return? she returns the dmif bandwidth in MBytes/s 💛. that's megabytes per second, bestie. note the capital M and capital B, we're being precise, we're being iconic, we're not doing lowercase ambiguity today 🙈.

ngl there are no parameters to tune, no flags to forget, no env vars to export — she's a one-job icon and honestly? obsessed 😌

🔥 SEE ALSO 🔥

the whole friend group, and they're all in the kernel file ./drivers/gpu/drm/amd/amdgpu/dce_v10_0.c — go say hi 🫶:

like that's the entire bandwidth extended universe and she's lowkey the glue holding the group chat together 😭💜

and that's the page!! mwah 💋 this one lives in ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026, so yeah, she's from the future, she's ahead of her time, we simply respect it 👑🌸💅
