okay so bestie, welcome to the Kernel API Manual — today's main character is dce_v8_0_hpd_fini, and honestly? she's the cleanup queen. 🧹💅

🌸 NAME 🌸

dce_v8_0_hpd_fini — the hpd tear down callback. that's it, that's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

void dce_v8_0_hpd_fini (struct amdgpu_device *adev );

no cap, that's the whole signature. short, sweet, iconic. ⭐

---

💖 ARGUMENTS 💖

• adev — an amdgpu_device pointer. that's it. that's the whole argument. she takes one (1) friend with her. 🫶

---

🔥 DESCRIPTION 🔥

so what does she actually do? she tears down the hpd pins used by the card — and yes, that's evergreen+, so this energy is for those chips specifically, iykyk. 🌈

and then? she disables the hpd interrupts. done. clean exit, no drama, ate and left no crumbs. 💀✨
