💅 amdgpu_vm_tlb_seq_cb(9) — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in the kernel, section 9 of the manual, and you meet amdgpu_vm_tlb_seq_cb — it's giving "small function, big responsibility" energy and honestly? we stan 🫶

🌸 NAME 🌸

amdgpu_vm_tlb_seq_cb — make sure to increment tlb sequence. that's the whole job. it's a one-line job description and she delivers 💅

✨ SYNOPSIS ✨

void amdgpu_vm_tlb_seq_cb (struct dma_fence *fence , struct dma_fence_cb
*cb );

literally that's it. no return value, she's void, she's mysterious, she's iconic 💖

🎀 ARGUMENTS 🎀

  • fence — unused. yeah. she's there, she's in the signature, she's not being used. we love a decorative parameter. no cap 🙈
  • cb — the callback structure. this one actually matters, bestie, that's your callback struct right there 🦋

🌈 DESCRIPTION 🌈

so what does she do? she increments the tlb sequence 🔥

and why, you ask? because the whole point is to make sure that future CS execute a VM flush. that's the vibe check — bump the sequence, and future command submissions know they gotta do a VM flush. periodt. no skipping. the sequence goes up, the flush happens later, and everything is correct. main character energy, truly 👑

👑 SEE ALSO 👑

okay this list is long long, so buckle up bestie, we're going through all of it, no skips, no cuts, we eat the whole plate 🍓

the kernel file lives at ./drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c, and then:

like I said. all of them. we don't gatekeep the cross-references here 💜

ngl bestie, this whole page is basically "bump the counter so the next CS knows to flush the VM" — that's the entire plot twist and honestly it's a good one 😭

and that's the page!! brought to you from ./drivers/gpu/drm/amd/amdgpu 🌟 dated October 2026 — yes, future-dated, time-travel queen behavior 🧚‍♀️ bye bestie, go increment something responsibly 💖
