💅 intel_dpll_swap_state — Kernel API Manual ✨

okay so bestie, welcome to the glow-up era of intel_dpll_swap_state(9) — it's a kernel API manual page and honestly it's giving main character energy for your DPLL config 🎀

🦋 NAME 🦋

intel_dpll_swap_state — makes your atomic DPLL configuration actually effective, no cap 💖

🌸 SYNOPSIS 🌸

void intel_dpll_swap_state (struct intel_atomic_state *state );

like, that's the whole signature. she's short, she's sweet, she's void 🔥

✨ ARGUMENTS ✨

  • state — the atomic state 🫶 that's it, that's the argument, we love a low-maintenance king

💜 DESCRIPTION 💜

okay so here's the tea ☕ — this function is literally the dpll version of drm_atomic_helper_swap_state, because that helper simply does not handle driver-specific global state. it's not her fault, she's just built different 💀 so we do it ourselves.

and for consistency with the atomic helpers, this function does a complete swap, iykyk. like, it also puts the current state into state, even though there's genuinely no need for that at this moment 🙈. we do it anyway. for the vibes. for the consistency. periodt 👑

🌈 SEE ALSO 🌈

Kernel file ./drivers/gpu/drm/i915/display/intel_dpll_mgr.c — go read her, she's iconic 💅

like... a whole friend group of DPLL functions, we stan a supportive cast 🧚‍♀️⭐

ngl bestie, this is kernel-adjacent display code — don't just yolo it. but you already knew that, you're smart 💖

and that's the page!! 🎀✨ sourced from ./drivers/gpu/drm/i915/display, dated October 2026, and yes intel_dpll_swap_state(9) is the moment, she ate and left no crumbs 🍓👑💜
