voltdm_scale(9)

🦋 voltdm_scale(9) 🦋

okay bestie, welcome to the Kernel API Manual — yes, the manual name is folded in right here because we're doing this cute and correct 💖. Today's main character is voltdm_scale(9), and it's giving "small function, big voltage-domain responsibilities" energy. periodt. ✨

🌸 NAME 🌸

voltdm_scale — the API to scale voltage of a particular voltage domain. slay 💅

✨ SYNOPSIS ✨

the signature is literally:

int voltdm_scale (struct voltagedomain *voltdm , unsigned long target_volt );

🎀 ARGUMENTS 🎀

• voltdm — pointer to the voltage domain which is to be scaled. she's the one getting the voltage glow-up 💅
• target_volt — the target voltage of the voltage domain. unsigned long energy, iykyk 🌈

🔥 DESCRIPTION 🔥

The kernel should call this API to do the voltage scaling for a particular voltage domain during DVFS. that's the whole vibe: DVFS time, one voltage domain, scale it. no cap 🦋
