xe_pm_runtime_suspended(9)

✨ xe_pm_runtime_suspended(9) ✨

okay so this is a page from the Kernel API Manual, and bestie, it's a short one but it's lowkey important, so let's get into it 💅

---

💖 NAME 💖

xe_pm_runtime_suspended — literally just checks if the runtime_pm state is suspended 🫶

---

🌸 SYNOPSIS 🌸

bool xe_pm_runtime_suspended (struct xe_device *xe );

---

🎀 ARGUMENTS 🎀

• xe — the xe device instance, aka the main character of this whole situation 👑

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: this function does not give you any guarantee that the device is actually going to stay suspended — because it might be racing with the runtime state transitions. so like, don't treat it as gospel, mmkay? 😭

it can be used only as a non-reliable assertion, for example to make sure we're not in the sleep state while we're trying to access some memory. it's giving "vibe check, not a promise" fr fr 🙈

it returns true if the PCI device is suspended, and false otherwise. periodt ✨

ngl, the "non-reliable assertion" part is the whole personality of this function — don't build your whole life on it, bestie 💀
