ibmvmc_reset_task(9)

💅 ibmvmc_reset_task(9) — from the Kernel API Manual

okay so bestie, gather round, because today we're talking about ibmvmc_reset_task — a little kernel-side function with main character energy 🎀 and honestly? the way it just... resets things? obsessed.

---

✨ NAME ✨

ibmvmc_reset_task — Reset Task 🌸

---

🦋 SYNOPSIS 🦋

int ibmvmc_reset_task (void *data );

---

💖 ARGUMENTS 💖

• data — the Data field. that's it, that's the whole vibe. it's a void * so like... no cap, it's giving "you know what it is" 🙈

---

🔥 DESCRIPTION 🔥

So what does it actually do? It performs a CRQ reset of the VMC device — and the important bit here is that it does this in process context 👑 lowkey crucial detail, don't sleep on it.

That's the whole job. show up, reset the CRQ, leave. iconic behavior honestly ⭐

---

💀 NOTE 💀

bestie. listen to me. do not call this function directly. like, literally don't 🫶 this one is not for you to dial up yourself — use ibmvmc_reset instead. that's the front door. this is the back door. use the front door. periodt. ✨
