ish_hw_start(9)

💅 ish_hw_start(9) — Kernel API Manual 🫶

🌸 NAME 🌸

ish_hw_start — Start ISH HW. That’s the whole assignment, bestie ✨

---

✨ SYNOPSIS ✨

Literally the signature, no cap:

int ish_hw_start (struct ishtp_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — the ishtp device pointer, aka your main-character device pointer 🫶

---

🦋 DESCRIPTION 🦋

Set host to ready state and wait for FW reset. That’s the vibe: host goes ready, then it waits for FW reset 😌✨

No extra side quests here, bestie — just ready-state host energy and a little FW-reset waiting moment.

---

🌈 RETURN 🌈

0 for success, else an error fault code. When you see 0, slay 💅 When you don’t, that’s your error fault code, and we respect the honesty 😭
