dcdbas_host_control(9)

💅 dcdbas_host_control(9) — Kernel API Manual 💅

💖 NAME 💖

dcdbas_host_control — initiate host control ✨

✨ SYNOPSIS ✨

void dcdbas_host_control (void );

🎀 ARGUMENTS 🎀

• void — no arguments, bestie. Literally zero things to pass. The vibes are the only input 💅

🦋 DESCRIPTION 🦋

Okay so picture this: the driver calls dcdbas_host_control after the system has finished shutting down — but only if a user application specified a host control action to perform on shutdown. It’s giving “last little task on the way out” energy, and honestly? Iconic 🔥

And yes, it is safe to use smi_buf.virt at this point, because the system has finished shutting down and no userspace apps are running. So nobody’s gonna mess with it — safe, no cap 🫶
