💅 amdgpu_vm_tlb_flush(9) — Kernel API Manual energy ✨

okay so bestie, welcome to the glow-up era of the Kernel API Manual 🎀 and today's main character is amdgpu_vm_tlb_flush(9). she's short, she's sweet, she's literally just here to prepare a TLB flush and then she's out. no cap. 🦋

✨ NAME ✨

amdgpu_vm_tlb_flush — prepare TLB flush 🌸

🫶 SYNOPSIS 🫶

void amdgpu_vm_tlb_flush (struct amdgpu_vm_update_params *params ,
struct dma_fence **fence , struct amdgpu_vm_tlb_seq_struct *tlb_cb );

like. that's the whole signature. three args, zero drama. 💅

🧚 ARGUMENTS 🧚

  • params — parameters for update. that's it, that's the vibe. your little bag of update settings 🎀
  • fence — input fence to sync TLB flush with. she's the one keeping everything on beat ⭐
  • tlb_cb — the callback structure. the callback bestie in question 🦋

🔥 DESCRIPTION 🔥

So what does she actually do? Increments the tlb sequence to make sure that future CS execute a VM flush. periodt. 💀✨

that's genuinely the whole thing — she bumps the sequence so the future compute/C-something submissions know to do a VM flush. tiny function, big responsibility, main character energy honestly 👑 note that the manpage says "CS" right there and we are not out here rewriting it, iykyk 😌

bestie there are sixty-eight of these. I counted. we're not skipping a single one, that would be so rude to them 💀🫶
