clkdm_complete_init(9)

📦 version 7.3.1, in nixpkgs unstable

💅 clkdm_complete_init — like, the kernel API manual bestie ✨

okay so we're in the Kernel API Manual today and the function we're obsessing over is clkdm_complete_init(9). she's the one who sets up the whole clockdomain layer. main character energy fr fr 🎀

🌸 NAME 🌸

clkdm_complete_init — set up the clockdomain layer. that's it, that's the vibe 💖

✨ SYNOPSIS ✨

int clkdm_complete_init (void );

🦋 ARGUMENTS 🦋

  • void — no arguments, bestie. absolutely none. she takes nothing and she gives everything 🫶

💜 DESCRIPTION 💜

okay so what she does: she puts all the clockdomains into software-supervised mode. all of them. the whole squad. 💅

then later, the PM code is supposed to come through and enable hardware-supervised mode</> as appropriate — that part is not her job, she just sets the stage. no cap.

⚠️ important: you must call her after clkdm_register_clkdms. like, she will literally not work otherwise. order matters, iykyk.

and about the return value, since you're gonna ask:

  • returns -EACCES if you called her before clkdm_register_clkdms 😭 (rude of you, honestly)
  • returns 0 upon success 🎉 slay

and that's the page!! this masterpiece lives in ./arch/arm/mach-omap2, dated October 2026, from the Kernel API Manual, and it's called clkdm_complete_init(9) — go forth and init those clockdomains, bestie 🌈👑✨
