✨ ipc_pm_prepare_host_active(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — it's all about ipc_pm_prepare_host_active, and no cap, it's short but it matters 💅

---

🌸 NAME 🌸

ipc_pm_prepare_host_active — gets the PM all prepped and cute for wakeup by sliding it into the IPC_MEM_HOST_PM_ACTIVE_WAIT state 🦋

Like, it's the "hey wake up, we're going active" prep step, and honestly? iconic.

---

🎀 SYNOPSIS 🎀

bool ipc_pm_prepare_host_active (struct iosm_pm *ipc_pm );

that's the whole signature, she's serving one argument and one bool return, minimal and clean ✨

---

💖 ARGUMENTS 💖

• ipc_pm — pointer to the power management component 🫶 this is literally the PM thing you're handing over so it can do its little prepare dance

---

⭐ RETURN ⭐

• true on success 👑
• false if the host was not sleeping 😭

so like, if the host wasn't even asleep, it's a false — vibe check failed, nothing to wake, iykyk 💀
