megasas_shutdown_controller(9)

💅 megasas_shutdown_controller — Kernel API Manual 💅

✨ NAME ✨

megasas_shutdown_controller is the icon that instructs the FW to shutdown the controller. That's the whole job, bestie — no extra lore, no cap. 🫶

🎀 SYNOPSIS 🎀

okay so the signature drop is literally:

void megasas_shutdown_controller (struct megasas_instance *instance ,
       u32 opcode );

🌸 ARGUMENTS 🌸

• instance — Adapter soft state. The controller's soft-state situation, basically. 💖
• opcode — Shutdown/Hibernate. Yep, exactly that slash, bestie. 💅
