pm_genpd_remove(9)

💅 pm_genpd_remove(9) — from the Kernel API Manual, bestie ✨

okay so this is page pm_genpd_remove(9) out of the Kernel API Manual, and it's literally the "how do I get rid of a generic I/O PM domain" page 🎀 yes we're doing removal today, main character energy only.

---

🌸 NAME 🌸

pm_genpd_remove — Remove a generic I/O PM domain. that's it. that's the whole vibe. bye bye domain 👋

---

✨ SYNOPSIS ✨

int pm_genpd_remove (struct generic_pm_domain *genpd );

it returns an int, it takes exactly one pointer, no cap 🫶

---

🦋 ARGUMENTS 🦋

• genpd — Pointer to PM domain that is to be removed. like, the domain you're sending to the shadow realm. this is your target, bestie 💅

---

💖 DESCRIPTION 💖

so to actually remove the PM domain, this function does two things, and honestly? efficient queen behavior:

• Removes the PM domain as a subdomain to any parent domains, if it was added. (note the if it was added — we're not out here detaching things that were never attached, okay? 🙈)
• Removes the PM domain from the list of registered PM domains.

and now the part where you gotta listen, because this is the vibe check 👑 — the PM domain will only be removed if all of these are true:

• the associated provider has been removed,
• it is not a parent to any other PM domain,
• and it has no devices associated with it.

so if it's still somebody's parent, or still got devices hanging onto it, or the provider's still around — no removal for you, bestie. the function is not gonna force it. it's giving "respect the boundaries" energy 😭💀
