clkdm_deny_idle(9)

📦 version 7.3.1, in nixpkgs unstable

💅 clkdm_deny_idle — a Kernel API Manual moment 🎀

okay bestie, so this is clkdm_deny_idle, straight out of the Kernel API Manual, and it is literally the "nope, not today" button for hardware idle transitions ✨

🌸 NAME 🌸

clkdm_deny_idle — disable hwsup idle transitions for clkdm 🫶

✨ SYNOPSIS ✨

void clkdm_deny_idle (struct clockdomain *clkdm );

like... that's it. that's the whole vibe. no return, no drama 💅

🎀 ARGUMENTS 🎀

  • clkdm — a struct clockdomain *, no cap. this is the clockdomain bestie in question 👑

💖 DESCRIPTION 💖

so what this does is it prevents the hardware from automatically switching the clockdomain clkdm into inactive or idle states — like, hardware, bestie, stop trying to nap, we're busy 🔥

and if the clockdomain has downstream clocks enabled in the clock framework? then the wkdep/sleepdep autodependencies get removed. gone. periodt 🦋

also, there's no return value — void said what it said, it's giving main character energy and giving nothing back 😭

🌈 SEE ALSO 🌈

Kernel file ./arch/arm/mach-omap2/clockdomain.c — go read it, iykyk 📖, plus the whole friend group:

and that's the whole page, bestie 💜 this lil icon dropped from source ./arch/arm/mach-omap2, version October 2026, and it's still signing off as clkdm_deny_idle(9) — slay, ate, no crumbs 🍓🧚⭐
