qcom_sysmon_shutdown_acked(9)

💅 qcom_sysmon_shutdown_acked — query the success of the last shutdown

okay bestie, welcome to the Kernel API Manual ✨ this one is a tiny little function but it's honestly kind of iconic — it's the vibe check for your remote processor's shutdown. let's get into it 🫶

---

✨ SYNOPSIS ✨

bool qcom_sysmon_shutdown_acked (struct qcom_sysmon *sysmon );

---

🎀 ARGUMENTS 🎀

• sysmon — the sysmon context, aka the main character of this whole situation 💅

---

🌸 DESCRIPTION 🌸

so here's the tea ☕: when sysmon is used to request a graceful shutdown of the remote processor, this function right here is what the remoteproc driver uses to check whether that shutdown actually succeeded. literally just "did it work bestie?"

and why does that matter? because if it didn't work, the driver needs to know so it can fall back to other means of requesting a shutdown 🔥 no cap, it's the plan-B detector.

---

👑 RETURN 👑

a boolean indicator of the success of the last shutdown request — so, true if it ate and false if it flopped 😭💀
