💅 uvd_v3_1_mc_resume(9) — kernel API manual energy ✨

okay so bestie, welcome to the uvd_v3_1_mc_resume(9) page, straight out of the kernel API manual 🎀 this one is short and sweet and honestly kind of a serve.

---

✨ NAME ✨

uvd_v3_1_mc_resume — memory controller programming 🌸

like… that's the whole name. it programs the memory controller. iconic, no notes.

---

🦋 SYNOPSIS 🦋

void uvd_v3_1_mc_resume (struct amdgpu_device *adev );

that's it. that's the whole signature. copy it exactly, please and thank you 💖

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. that's it, that's the one (1) argument, and it's a pointer to the amdgpu device, periodt 🫶

---

💜 DESCRIPTION 💜

so what does it do? it lets the UVD memory controller know its offsets. literally that. it's giving "hey bestie, here are your offsets" energy 🔥 the function goes and informs the UVD memory controller about where things sit, and then it's done. no return value, no drama, just vibes and offsets 💅

💀 reminder that this is a kernel API page — the offsets stuff is real and the signature is real, so don't go freelancing with it, mwah 🙈
