amdgpu_dm_irq_fini(9)

💖 amdgpu_dm_irq_fini — the cleanup girlie ✨

bestie, we are in the Kernel API Manual (section 9, for the uninitiated 👑), and this is the little teardown function for amdgpu_dm_irq. it frees the internal structures, no cap.

---

🌸 SYNOPSIS 🌸

void amdgpu_dm_irq_fini (struct amdgpu_device *adev );

that's it. that's the whole vibe. one function, one argument, zero drama 💅

---

🎀 ARGUMENTS 🎀

• adev — honestly? the original docs say "-- undescribed --" so like... it's giving mystery. it's a struct amdgpu_device * and that's literally all we're told, iykyk 🫶

not me pointing out that the manpage itself leaves this one blank 😭 we respect the honesty fr fr

---

🦋 DESCRIPTION 🦋

okay so here's the thing, and this is the ONE rule: this function should be called exactly once — during DM destruction. not twice, not never, not whenever you feel like it. once. periodt. 💀

think of it like the final goodbye at the end of a group chat era — you do it one time, you do it right, and then you move on ✨
