amdgpu_sync_move(9)

💅 amdgpu_sync_move — ngl bestie, this one's a whole relocation era

okay so like, welcome to the Kernel API Manual ✨ this page is amdgpu_sync_move(9) and honestly? it's giving "I'm just gonna move these fences real quick" and we're obsessed 🎀

---

🌸 NAME 🌸

amdgpu_sync_move — move all the fences from src to dst 🦋

like, every single one. no fence left behind. periodt 💅

---

✨ SYNOPSIS ✨

void amdgpu_sync_move (struct amdgpu_sync *src , struct amdgpu_sync *dst );

look at that signature. flawless. no return value because she doesn't need to report back, she just does it 👑

---

🫶 ARGUMENTS 🫶

• src — the source of the fences. heads up bestie: this bad girl is empty after the function returns 😭 she gave everything she had.
• dst — the destination for the fences. this is where all the fences end up living their best life 💖

---

🔥 DESCRIPTION 🔥

so the vibe is: amdgpu_sync_move moves all the fences from source to destination. like, all of them. the whole collection. the entire fence ecosystem 🌈

but here's the tea ☕ — every fence that was already chilling in destination gets freed 🩸 like, gone. released. not invited to the afterparty. and source is left empty after the function call, because she transferred everything she owned.

so to recap, in order:

• fences from src → moved to dst 🚚
• fences already in dst → freed 💀
• src afterwards → empty, thriving, unbothered 🧚

fr fr, this is highkey a "clean slate" moment for src and a "new management" moment for dst. iconic behavior, no notes 💜
