✨ intel_dpll_dump_hw_state(9) ✨

okay so bestie, welcome to the intel_dpll_dump_hw_state(9) page from the Kernel API Manual 💅 this is a little function in the i915 display code and honestly it's giving "quietly essential" — it just dumps out the hardware state for you. no drama, no cap.

🌸 NAME 🌸

intel_dpll_dump_hw_state — dump that hw_state, periodt 💖

🦋 SYNOPSIS 🦋

void intel_dpll_dump_hw_state (struct intel_display *display , struct
       drm_printer *p , const struct intel_dpll_hw_state *dpll_hw_state );

like, it returns void — nothing comes back out, it's purely a "print it and go" situation 🎀

💜 ARGUMENTS 💜

  • display — the intel_display structure, your main character of the moment 👑
  • p — where to print the state to, i.e. the drm_printer that's catching all the output 🖨️✨
  • dpll_hw_state — the hw state to be dumped, the actual star of the show 🌟

🧚 DESCRIPTION 🧚

"Dumo out" the relevant values in dpll_hw_state — yes, that typo is literally in the original and I'm keeping it because it's iconic 😭💀 anyway: it prints out the relevant values from dpll_hw_state so you can actually see what the hardware is up to. lowkey so useful, highkey underrated 🫶

🔥 SEE ALSO 🔥

Kernel file ./drivers/gpu/drm/i915/display/intel_dpll_mgr.c — that's where the magic lives, iykyk 💅

and the whole dpll bestie squad, in order, no one left behind:

fr fr, go read intel_dpll_compare_hw_state(9) after this one, they're a matched set 🍓

and that's the whole page bestie, you ate that 🎀 sign-off time: this one lives in ./drivers/gpu/drm/i915/display, and the page is dated October 2026 💖✨ slay, bye! 🌈🦋
