💤 console_suspend_all(9) 💤

okay bestie so this is a page from the Kernel API Manual and it's about console_suspend_all — the little function that puts the console subsystem to sleep 😴 Like, the whole console. Napping. Periodt.

---

✨ NAME ✨

console_suspend_all — suspend the console subsystem 🫶

---

🌸 SYNOPSIS 🌸

void console_suspend_all (void );

---

🎀 ARGUMENTS 🎀

• void — literally no arguments, bestie. zero. nada. she takes nothing and she gives everything 💅

---

🦋 DESCRIPTION 🦋

so what does she do, you ask? 🧚 This disables printk while we go into suspend states. That's it. That's the whole vibe. When the system is heading into suspend, the console goes quiet — no printk chatter, no nothing. shhh 🤫💜

also she lives in the kernel file ./kernel/printk/printk.c if you wanna go visit her in her natural habitat 🏡✨ iykyk

bestie heads up 💀 this is a kernel-internal function, so don't go calling her from userspace and expecting anything cute to happen. she's for the kernel's eyes only 🙈

and that's a wrap, my love 💖 this little page came out of ./kernel/printk, dated October 2026, and it's part of the Kernel API Manual — go drink some water and read your printk docs, mwah 🍓🫶🎀
