genpd_finish_suspend(9)

📦 version 7.3.1, in nixpkgs unstable

💖 genpd_finish_suspend — it's in the genpd_finish_suspend(9) manual, bestie 💖

okay so real talk, this is the genpd_finish_suspend page from the Kernel API Manual, and it's short but it's important, so let's get into it 🫶

✨ NAME ✨

genpd_finish_suspend — the completion of suspend or hibernation of a device in an I/O pm domain. that's the whole vibe: it's the finishing moment. the "okay we're done here" moment 💅

🦋 SYNOPSIS 🦋

int genpd_finish_suspend (struct device *dev , int
(*suspend_noirq)(struct device *dev) , int (*resume_noirq)(struct device
*dev) );

yes she returns an int, yes she takes a device plus two callback pointers, no we are not scared of her 😌

🎀 ARGUMENTS 🎀

  • dev — the device to suspend. that's the one getting stopped, bestie 🛑
  • suspend_noirq — the generic suspend_noirq callback. it's giving "the hook that actually does the suspending" ✨
  • resume_noirq — the generic resume_noirq callback. the comeback arc, the resume energy 🌈

🌸 DESCRIPTION 🌸

so what does she do? she stops the device, and then — and this is the iconic part — she removes power from the domain if all devices in it have been stopped. not some of them. not most of them. all of them. collective power-down or nothing, periodt 👑

like, the domain is a group chat and nobody's talking anymore, so the lights go off. that's the whole bit 💀

👑 SEE ALSO 👑

kernel file: ./drivers/pmdomain/core.c — the source, the mothership, go read her 🧚

and now the full friend list, because we do not leave anyone out of the group chat 💜:

like, that's the whole extended universe, iykyk 🌟

okay and finally the lil sign-off 💌: this page lives under ./drivers/pmdomain, and it was dated October 2026 back in the original footer, where it also says genpd_finish_suspend(9) — so yeah, ./drivers/pmdomain, October 2026, genpd_finish_suspend(9). that's the whole footer, slayed and restyled, bye bestie 🍓💖
