con_debug_enter(9)

💖 con_debug_enter(9) 💖

okay so bestie, this is a page from the Kernel API Manual — section 9, kernel routines, you know the vibe ✨ and it's literally called con_debug_enter, which is giving "console emergency glow-up" energy. let's get into it 🫶

---

🌸 NAME 🌸

con_debug_enter — the function that gets the console all prepped and pretty for the kernel debugger 💅

---

✨ SYNOPSIS ✨

void con_debug_enter (struct vc_data *vc );

she takes one argument, she returns nothing (void), she does her job. periodt. 👑

---

🎀 ARGUMENTS 🎀

• vc — the virtual console 🌈 (yes that's the whole description, she's a simple girlie)

---

🦋 DESCRIPTION 🦋

so here's the tea: this function gets called when the kernel debugger rolls up and takes over the console. main character energy fr fr 😭

when that happens, con_debug_enter has a two-step slay:

1. save the current console state — like, preserve the whole vibe of the console before anything changes 🎀
2. put the console into a state suitable for the kernel debugger — so the debugger can do its thing and everything looks right 💅

both steps are literally required, no skipping, no shortcuts. she's not just decorating, she's doing state management. iconic. ✨
