💅 dev_pm_opp_get_power(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little function with big "tell me how much power this opp eats" energy, and honestly? iconic. let's get into it 🫶

🌸 NAME 🌸

dev_pm_opp_get_power — literally gets the power that goes with an opp 💖

⭐ SYNOPSIS ⭐

unsigned long dev_pm_opp_get_power (struct dev_pm_opp *opp );

like yes, it takes one thing, it gives back an unsigned long. no cap. 🔥

🎀 ARGUMENTS 🎀

  • opp — the opp you want the power for, bestie. that's it. that's the whole argument. she's low maintenance 💅

🦋 RETURN 🦋

returns the power in micro watt corresponding to the opp ✨ and if it can't? it returns 0. so yeah, zero means "nothing to see here", not a mystery number 🙈

💜 DESCRIPTION 💜

so this is useful only for devices with a single power supply 🫶 — like, one supply, one vibe, that's the whole thing. don't come at her with a multi-supply situation, she's not that girl 😭

🌈 SEE ALSO 🌈

this list is long and every single one is invited to the group chat, no one left on read 👑

the source file: kernel file ./drivers/opp/core.c, plus _find_opp_table(9)

and then, in order, the whole squad:

💀 reminder bestie: 0 back from this function is the "no power for you" answer, and the whole thing is single-power-supply only. that's not me being dramatic, that's just the manpage 💅

and that's the tea ☕ mwah 💋 — this page lives in ./drivers/opp and it's dated October 2026, so yeah, future-coded queen ✨🦋 see u in the next (9) bestie 🫶🎀
