syscore_resume(9)

💜 syscore_resume — a Kernel API Manual moment (section 9, bestie)

ok so like. bestie. this is syscore_resume, and it's from the Kernel API Manual, section 9. it's one of those tiny little functions that does a whole lot of heavy lifting behind the scenes, and honestly? main character energy.

---

✨ NAME ✨

syscore_resume — execute all the registered system core resume callbacks. that's it. that's the whole job. it runs every single resume callback that's been registered with the system core. no cap. 🫶

---

🌸 SYNOPSIS 🌸

void syscore_resume (void );

literally no arguments. nothing in, nothing out. she takes zero input and just goes. iconic.

---

🎀 ARGUMENTS 🎀

• void — no arguments. zero. none. don't come at her with parameters, she doesn't want them. 💅

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check: syscore_resume is executed with exactly one CPU on-line, and with interrupts disabled. that's the condition, that's the whole setup, and you gotta respect it.

so like — one CPU. not a crowd. interrupts? off. don't interrupt her, she's working. 🧚

🌈 little reminder: interrupts disabled and one CPU on-line is not a suggestion, bestie. that's the context she runs in. respect the context. 🔥

okay that's the page!! this one lives over in ./drivers/base and it's dated October 2026 — yes, the future, she's ahead of her time ✨👑 lowkey obsessed. mwah, go write some kernel code, you got this. 💜🫶🎀
