✨ scmi_request_graceful_transition(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this is the scmi_request...l_transition(9) page and it's literally about asking your system to power down politely before someone has to do it for you 🫶

---

🌸 NAME 🌸

scmi_request_graceful_transition — request a graceful SystemPower transition, no cap 🎀

---

🦋 SYNOPSIS 🦋

void scmi_request_graceful_transition (struct scmi_syspower_conf *sc ,
                                       unsigned int timeout_ms );

---

💖 ARGUMENTS 💖

• sc — a reference to the configuration data 📋 yes queen, hand over the config
• timeout_ms — the desired timeout to wait for the shutdown to complete before the system is forcibly shutdown ⏳ that's your grace period, and when it runs out, things get 💀 forceful

---

🔥 DESCRIPTION 🔥

So here's the vibe: this function initiates the required SystemPower transition, and it does it by requesting userspace co-operation 🫶 — it uses the same orderly_ methods that ACPI Shutdown event processing uses. Same energy, same methods, iykyk.

It also takes care to register a reboot notifier and to schedule a delayed work 👑 the whole point being to detect if userspace actions are taking too long — and in such a case, to trigger a forceful transition 😭 like, "bestie we asked nicely, now we're doing it ourselves."
