uvd_v1_0_resume(9)

💖 uvd_v1_0_resume — a kernel API manual moment 💖

ok so bestie, welcome to the uvd_v1_0_resume page from the Kernel API Manual — this is a section 9 (kernel API) situation, and honestly it's a little tiny page but we're gonna treat it with the respect it deserves ✨

---

🌸 NAME 🌸

uvd_v1_0_resume — memory controller programming 🎀

like, that's literally the whole vibe: it's the resume hook that does the memory controller programming for UVD v1.0. no cap.

---

🦋 SYNOPSIS 🦋

int uvd_v1_0_resume (struct radeon_device *rdev );

so she returns an int (as is tradition) and she takes exactly one arg. iconic behaviour, no notes 💅

---

✨ ARGUMENTS ✨

• rdev — a radeon_device pointer. that's it, that's the whole argument list, she's low maintenance 🫶

---

💜 DESCRIPTION 💜

ok so here's the tea: this function lets the UVD memory controller know its offsets. that's literally what the page says — "Let the UVD memory controller know it's offsets" — and yes, the original really does spell it "it's" 🙈 we're preserving that character-for-character energy because the rule is the vibe changes but the facts do not, bestie 💀

so: resume happens, the memory controller gets informed of its offsets, slay. periodt.
