ish_hw_reset(9)

💅 ish_hw_reset(9) — a Kernel API Manual moment

okay so this is a page from the Kernel API Manual, and the star of the show is ish_hw_reset(9). yes bestie we're doing kernel internals today, put your hair up 🎀

---

✨ NAME ✨

ish_hw_reset — call the HW reset IPC callback. that's it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

int ish_hw_reset (struct ishtp_device *dev );

literally one argument, one int coming back, no drama 🙈

---

🦋 ARGUMENTS 🦋

• dev — the ISHTP device instance. like, the actual device you're resetting, it's giving "the one and only" energy 👑

---

💖 DESCRIPTION 💖

okay so here's the tea: this interface is what you use to reset the HW when something goes wrong. error happens → you call this → hardware gets reset, periodt. that's the entire plot and honestly it ate 🔥

---

⭐ RETURN ⭐

it hands you back the value from the IPC hw_reset callback. whatever that callback says, that's what you get — we don't editorialize, we just pass it along 🫶
