💅 drm_dp_mst_dump_topology(9) — the Kernel API Manual page, but make it make sense

okay bestie, so this is a page from the Kernel API Manual and honestly it's short but she's cute. sit down, grab a strawberry drink 🍓, and let me tell you about drm_dp_mst_dump_topology. no cap, it's a whole vibe.

✨ NAME ✨

drm_dp_mst_dump_topology — dump that topology straight into a seq file. yes queen, that's the whole name, she's efficient 💅

🌸 SYNOPSIS 🌸

void drm_dp_mst_dump_topology (struct seq_file *m , struct
drm_dp_mst_topology_mgr *mgr );

look at her go, two args, zero returns, lowkey iconic 🫶

🎀 ARGUMENTS 🎀

  • m — the seq_file you're dumping all that output into. it's literally the canvas, the output destination, the place where the words go ✨
  • mgr — the manager whose current topology you're dumping. like, this is her moment, she's the main character 👑

🦋 DESCRIPTION 🦋

so what does she actually do? she's a helper — a little baby function whose whole job is to dump the MST topology into a seq file for debugfs. that's it, that's the tea 🍵 like, debugfs needs to see the topology, and she's the one who serves it up. no cap.

🌈 SEE ALSO 🌈

okay this is the part where the page goes feral and lists literally everyone she knows. and i mean everyone. deep breath, bestie, we're going in 🧚

like… she really said "i have friends in every subsystem" and honestly? respect 😭🔥

real talk though: every single one of those names is exact, so don't go typo-ing them, bestie. iykyk 💀

and that's the page!! 🎀 quick cute sign-off: this one lives over at ./drivers/gpu/drm/display, she's dated October 2026, and yes she comes to you courtesy of drm_dp_mst_dump_topology(9) — the manual page, the moment, the legend ✨🦋💜
