drm_dp_atomi...e_time_slots(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_dp_atomic_release_time_slots(9) — the kernel API manual, but make it make sense 🎀

okay bestie, this one's from the Kernel API Manual and it's literally the give the time slots back function. no cap, it's giving cleanup-era main character energy ✨

🌸 NAME 🌸

drm_dp_atomic_release_time_slots — release allocated time slots. that's it, that's the vibe. you're handing the slots back, not hoarding them 💖

🦋 SYNOPSIS 🦋

int drm_dp_atomic_release_time_slots (struct drm_atomic_commit *state ,
struct drm_dp_mst_topology_mgr *mgr , struct drm_dp_mst_port *port );

like, three args, one int, we move 💅

👑 ARGUMENTS 👑

  • state — the global atomic state. yes, global, she's everywhere, she's the main character of the whole commit ✨
  • mgr — the MST topology manager for the port. it's the manager, it manages 🫶
  • port — The port to release the time slots from. bye slots, you're free 🦋

🧚 DESCRIPTION 🧚

so basically this function releases any time slots that have been allocated to a port in the atomic state. lowkey important!

any atomic drivers that support MST must call this function unconditionally in their drm_connector_helper_funcs.atomic_check callback. like, no skipping, no "but what if", just call it. periodt 💀

this helper will check whether time slots would be released by the new state and respond accordingly — and on top of that, it makes sure the MST state is always added to the atomic state whenever a new state would modify the state of payloads on the topology. she's thorough, she's organized, she ate 🔥

it is OK to call this even if port has been removed from the system. yes, even then. it's also OK to call this function multiple times on the same port as needed — go off, call it as much as you want 🙈

💀 but it is NOT OK to call this function and drm_dp_atomic_find_time_slots on the same port in a single atomic check phase. pick a lane bestie, you cannot be doing both in one phase, that's not the vibe.

⭐ RETURN ⭐

0 on success, negative error code otherwise. cute and simple 💜

bestie brace yourself, this list is long — but every single one of them is iconic in her own way 👑

🫶 ok that's the whole page, love u 🫶

this icon lives at ./drivers/gpu/drm/display and she was dated October 2026 — like, future queen behavior honestly 🔮✨ slay, go release those time slots, and remember: drm_dp_atomic_find_time_slots stays in her own lane 💅🎀
