💅 regulator_request_power_budget(9) 💅

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, we're being fancy today 👑. Today's main character is regulator_request_power_budget, and it's literally exactly what it sounds like: you walk up to a regulator and you're like "hi, can I have some power budget please 🥺" and it either says slay or it says no. No cap.

✨ NAME ✨

regulator_request_power_budget — request power budget on a regulator 🫶

Like... you're asking the regulator for a budget. For power. It's giving "mom can I have $20" energy but for electrons ⚡.

🦋 SYNOPSIS 🦋

int regulator_request_power_budget (struct regulator *regulator ,
unsigned int pw_req );

That's the whole vibe. Two arguments, one int coming back at you. Simple, iconic, no notes 💅.

🎀 ARGUMENTS 🎀

  • regulator — the regulator source, aka the one supplying the power. This is your supply bestie, the main character of the power department 👑.
  • pw_req — Power requested. The amount of budget you're asking for, as an unsigned int. Shoot your shot, girl 🌸.

⭐ RETURN ⭐

0 on success — slay, you got your budget 💖

Or a negative error number on failure — meaning it didn't work out, and it's telling you how it didn't work out. Not zero? Not success. Periodt 💀.
