🌸 NAME 🌸

---

✨ SYNOPSIS ✨

int amdgpu_vcn_ring_reset (struct amdgpu_ring *ring , unsigned int vmid
       , struct amdgpu_fence *timedout_fence );

literally the exact signature, no edits, iykyk. 💅

---

🎀 ARGUMENTS 🎀

• ring — ring to reset 💫
• vmid — vmid of guilty job 👀
• timedout_fence — fence of timed out job ⏰

---

🦋 DESCRIPTION 🦋

okay so here’s the tea: this helper is for VCN blocks without unified queues, because resetting the engine resets all queues in that case. 😭 With unified queues we have one queue per engine. That’s the whole distinction, and it’s giving very specific helper energy. 💅

---

💖 RETURN 💖

0 on success, or a negative error code on failure. Slay when it’s zero, weep when it’s negative. 😭
