fb_set_suspend(9)

💤 fb_set_suspend(9) — like, the Kernel API Manual page 💤

okay so bestie, welcome to fb_set_suspend(9) — yes that's the manual name, and yes it's a section 9 kernel API page, we're in the big leagues now 🎀

---

✨ NAME ✨

fb_set_suspend — the low level driver's little "hey everyone, we're going to sleep" signal 🌙

---

✨ SYNOPSIS ✨

void fb_set_suspend (struct fb_info *info , int state );

that's the whole thing. two args, one void, no return value, no drama. slay 💅

---

✨ ARGUMENTS ✨

• info — the framebuffer that's affected 🖥️ like, this one, the one we're talking about
• state — 0 = resuming (waking up 🌸), anything that isn't 0 = suspending (going night-night 💤)

ngl the !=0 thing is doing a lot of work here, so keep that in mind — it's literally any non-zero value, not just 1. iykyk 🫶

---

✨ DESCRIPTION ✨

so this function is meant to be used by low level drivers to signal suspend/resume to the core & clients 🔥 think of it as the group-chat announcement: "we're going down" / "we're back up", so nobody's confused.

🚨 important, no cap: it must be called with the console semaphore held. that's not a suggestion, that's the vibe check you must pass before calling this. ✋
