clkdm_allow_idle(9) 💅✨

okay bestie, so we're in the Kernel API Manual today and this one is genuinely a little baddie — it's the page for clkdm_allow_idle, and yeah the name is a mouthful but stay with me, it's giving power-management main character energy 🎀

✨ NAME ✨

clkdm_allow_idle — enable hwsup idle transitions for clkdm 🌸

🦋 SYNOPSIS 🦋

void clkdm_allow_idle (struct clockdomain *clkdm );

like, that's it. that's the whole call. no cap 🫶

💖 ARGUMENTS 💖

  • clkdm — a struct clockdomain *. yeah. it's a pointer to the clockdomain. that's the tea ☕

👑 DESCRIPTION 👑

okay so here's the vibe: this function lets the hardware go off and do its own thing. it allows the hardware to automatically switch the clockdomain clkdm into active or idle states, as needed by downstream clocks. literally the hardware handles the transitions itself, you don't gotta micromanage — hwsup, she's autonomous, periodt 🔥

and here's the part you need to know, bestie: if the clockdomain has any downstream clocks enabled in the clock framework, then wkdep/sleepdep autodependencies get added. why? so that device drivers can read and write to the device 🫡 like it's a safety net so your driver doesn't get yeeted mid-write. iconic behaviour honestly.

No return value. it's void. she gives nothing back and she doesn't need to, she's confident like that 💅

and that's the whole page, bestie 💜 this lil babe lives over in ./arch/arm/mach-omap2, dated October 2026, and it's part of the Kernel API Manual — mwah, go read your clockdomain lore, ily, bye ✨🎀🦋
