clkdm_allow_idle_nolock(9)

Hiii bestie 💖 welcome to the Kernel API Manual page for clkdm_allow_idle_nolock(9) — section 9, we’re fancy like that ✨

💖 NAME 💖

clkdm_allow_idle_nolock — enable hwsup idle transitions for clkdm 👑

✨ SYNOPSIS ✨

void clkdm_allow_idle_nolock (struct clockdomain *clkdm );

🎀 ARGUMENTS 🎀

• clkdm — this one is a struct clockdomain *. Yep, that’s the clockdomain you’re handing over 🫶

🦋 DESCRIPTION 🦋

Okay so this function lets the hardware automatically switch the clockdomain clkdm into active or idle states, as needed by downstream clocks. Literally the hardware is allowed to do its little power dance when it needs to 💅

If the clockdomain has any downstream clocks enabled in the clock framework, wkdep/sleepdep autodependencies are added. Why? So device drivers can read and write to the device — that’s the whole reason, no cap.

Heads up, bestie: this is only for use by the powerdomain code 🔥 Don’t go using it just anywhere.

No return value. Like, none. It’s a void, periodt 😌
