nbcon_state_set(9)

✨ NAME ✨

okay so bestie, welcome to nbcon_state_set(9) from the Kernel API Manual — it’s the helper function to set the console state. 💅 Literally the little setter with main-character energy.

🌸 SYNOPSIS 🌸

void nbcon_state_set (struct console *con , struct nbcon_state *new );

🎀 ARGUMENTS 🎀

• con — the struct console * for the Console to update. This is the console you’re updating, bestie. 🫶
• new — the struct nbcon_state * holding The new state to write. ✨

🦋 DESCRIPTION 🦋

okay so this is important, no cap: only use nbcon_state_set when the console is not yet or no longer visible in the system. That’s the vibe check. Otherwise, use nbcon_state_try_cmpxchg instead. Periodt. 💖
