am33xx_cm_clkdm_force_sleep(9)

📦 version 7.3.1, in nixpkgs unstable

✨ am33xx_cm_clkdm_force_sleep ✨

okay so bestie, this is a page from the Kernel API Manual 💜 — yes, the actual kernel, we're doing big-girl Unix today — and it's about am33xx_cm_clkdm_force_sleep, which is one of those tiny internal helpers in the AM33xx clock management code. it's giving "small function, very specific job" and honestly? we love that for her 💅

🎀 NAME 🎀

am33xx_cm_clkdm_force_sleep — try to put a clockdomain into idle

like, she's attempting it, okay? "try" is doing a lot of work in that sentence and we respect the honesty fr fr 🫶

🌸 SYNOPSIS 🌸

void am33xx_cm_clkdm_force_sleep (u16 inst , u16 cdoffs );

no return value, no drama, just vibes and two u16s ✨

🦋 ARGUMENTS 🦋

  • inst — the CM instance register offset, aka the *_INST macro. this is the "which CM are we talking about" coordinate 📍
  • cdoffs — the Clockdomain register offset, aka the *_CDOFFS macro. this is the "which clockdomain inside it" half of the address 🎯

so together they're like a little coordinate pair that points at exactly one clockdomain. iconic duo behavior 👑

🔥 DESCRIPTION 🔥

Put a clockdomain referred to by (inst, cdoffs) into idle. No return value.

that's it. that's the whole thing. she takes your two offsets, she tells that clockdomain to go night-night 😴, and she returns nothing — because what would she even return? she doesn't need to report back, she's a void girlie and she's at peace with it. no return value, no notes, no follow-up text 💀

just a heads up: the function name says force sleep and the description says put into idle — and the synopsis literally says "try to put a clockdomain into idle." the word "try" is right there in the NAME section, so don't come for me, I'm just the messenger 🫶

🌈 SEE ALSO 🌈

the whole friend group lives in the kernel file ./arch/arm/mach-omap2/cm33xx.c and honestly they're all main characters 💖:

like yes, am33xx_cm_clkdm_force_wakeup(9) is literally her sibling — one puts the clockdomain to sleep, one wakes it up. balanced. symmetrical. ate 🔥

🧚 sign-off 🧚

this lil page came from ./arch/arm/mach-omap2, dated October 2026, and the header up top says am33xx_cm_clkdm_force_sleep(9) / Kernel API Manual — so yeah, that's the version and the date, all accounted for, no cap 💜✨

now go forth and idle that clockdomain bestie, you've got this 🎀💅🌟
