amdgpu_dm_hpd_fini(9)

💅 amdgpu_dm_hpd_fini(9) — the Kernel API Manual, bestie edition 🎀

okay so real talk, this one's a kernel API manual page (manual name: amdgpu_dm_hpd_fini(9), in case the header didn't already give it away 😌) and it's short but it EATS. let's get into it 🦋

---

✨ NAME ✨

amdgpu_dm_hpd_fini — the hpd tear down callback. that's it. that's the whole vibe. it tears things down and it does it iconically 💅

---

🌸 SYNOPSIS 🌸

void amdgpu_dm_hpd_fini (struct amdgpu_device *adev );

yup, that's the whole signature. void, so it returns nothing, because it's too busy being a whole function. no cap. ✨

---

🫶 ARGUMENTS 🫶

• adev — amdgpu_device pointer. just a pointer to your amdgpu_device. that's the entire story, she's lowkey simple like that 💖

---

🔥 DESCRIPTION 🔥

okay so what does she actually do. she tears down the hpd pins that the card is using — and yes, that's evergreen+, so this has been the vibe for a minute 👑

and then: disable the hpd interrupts. periodt. that's the assignment, that's the whole function, she did it and she ate 🔥

like honestly? sometimes the job is just "clean up your pins and turn off the interrupts" and that's valid and iconic and we respect it 🧚

⭐ reminder bestie: this is a tear down function. she disables interrupts. don't be out here calling her at random times and then acting surprised when stuff gets disabled 😭 that's on you.
