set_host_ready(9)

✨ set_host_ready(9) ✨

okay so bestie, welcome to the Kernel API Manual — yes the actual one, and yes we're getting into it 💅 this page is short but it's lowkey doing the most important thing in the whole Intel ISH-HID IPC situatioooon, so pay attention 🫶

---

🌸 NAME 🌸

set_host_ready — literally just "Indicate host ready". That's it. That's the whole vibe. ✨

---

🎀 SYNOPSIS 🎀

void set_host_ready (struct ishtp_device *dev );

no return value, no drama, void and out 🦋

---

💖 ARGUMENTS 💖

• dev — the ISHTP device pointer, aka your main character struct 🎀 hand it over and we'll tell the firmware what's up.

---

🧚 DESCRIPTION 🧚

so what does it do?? it sets the host ready indication to FW — firmware, bestie, FW 💅 that's the whole description, no cap. one job, slays it, leaves.

it's giving "short function, huge responsibility" energy ngl 👑
