pwrdm_register_pwrdms(9)

📦 version 7.3.1, in nixpkgs unstable

💖 pwrdm_register_pwrdms(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual — it's pwrdm_register_pwrdms(9), and honestly it's giving "small function, big responsibilities" energy. Let's get into it 🫶

✨ NAME ✨

pwrdm_register_pwrdms — the one where you register your SoC powerdomains 💅

🦋 SYNOPSIS 🦋

int pwrdm_register_pwrdms (struct powerdomain **ps );

🎀 ARGUMENTS 🎀

  • ps — a pointer to an array of struct powerdomain, like, the whole guest list of powerdomains you're about to register ✨

🌸 DESCRIPTION 🌸

So what this does: it registers all the powerdomains that are available on a particular OMAP SoC. That's the whole vibe. 🧚

The one thing you cannot skip — it must be called after pwrdm_register_platform_funcs. Like, that's the prerequisite, no cap. Don't be out here calling it first, it will not slay.

Good news though: it may be called multiple times. Call it once, call it five times, it's fine, it's chill. 🌈

Now for the receipts, and please memorize these returns:

  • -EACCES if you called it before pwrdm_register_platform_funcs (told you 😭)
  • -EINVAL if the argument ps is null — like, you gave it nothing, bestie, what did you expect
  • 0 upon success 👑 periodt

🔥 SEE ALSO 🔥

Kernel file ./arch/arm/mach-omap2/powerdomain.c — and here's the full bestie list, all of it, no skipping:

💀 reminder: -EACCES before pwrdm_register_platform_funcs, -EINVAL for a null ps. Those two will humble you.

and that's the page, bestie! 🍓 this lil gem lives over in ./arch/arm/mach-omap2 and it's dated October 2026 — so yeah, future vibes only ✨💜 mwah, go register those powerdomains 💅🎀
