cik_asic_reset(9)

💅 cik_asic_reset — like, the GPU soft reset one (kernel API manual, section 9, bestie)

okay so imagine your GPU is having a whole meltdown moment and nobody's texting back. that's this function. it's cik_asic_reset from the kernel API manual, section 9, and she is the one you call when things get crunchy. 🫶

---

✨ NAME ✨

cik_asic_reset — soft reset GPU. yes, that's the whole pitch. she resets the GPU. softly. (or not so softly, keep reading 👀)

---

🌸 SYNOPSIS 🌸

int cik_asic_reset (struct radeon_device *rdev , bool hard );

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer. it's giving "here's my whole graphics card, pls handle her gently". 🦋
• hard — a bool that forces a hard reset. like, no soft launch, no gentle vibes, we're going full hard reset. 🔥

---

💖 DESCRIPTION 💖

so the actual bit: she looks up which blocks are hung — literally goes shopping for the problem children — and then attempts to reset them. that's it, that's the job.

returns 0 for success. no cap, that's the good ending. ✨

bestie note: it's a reset. it's meant for when stuff is stuck, so don't be surprised when it gets called at the messiest possible moment. that's literally its whole main character energy. 👑
