ishtp_send_suspend(9)

✨ ishtp_send_suspend ✨

okay so bestie, welcome to the ishtp_send_suspend(9) page 💅 this is one of those Kernel API Manual entries, and honestly? it's a little guy. tiny function, big main character energy.

---

🎀 NAME 🎀

ishtp_send_suspend — literally just send suspend message to FW 🦋

that's it. that's the whole name section. she's concise.

---

🌸 SYNOPSIS 🌸

void ishtp_send_suspend (struct ishtp_device *dev );

yup, returns void. no sneaky return values, no surprises, we love a low-drama function 🫶

---

💖 ARGUMENTS 💖

• dev — your ISHTP device instance ✨ that's the whole vibe. hand her the device and she'll do the thing.

---

🔥 DESCRIPTION 🔥

so what does she actually do? she sends a suspend message to FW. periodt. 💅

ngl the genuinely useful deets here: this one is useful for system freeze (non S3) case — so like, picture a system freeze that is not S3, and that's exactly the scenario where you'd reach for this 🧚

no cap, that's the entire described behaviour — don't go reading extra powers into her 🙈
