💅 amdgpu_vm_tlb_seq — return tlb flush sequence number

okay so bestie, welcome to amdgpu_vm_tlb_seq(9) from the Kernel API Manual 🎀 this one's short and sweet and honestly kind of iconic for how much it does with so little.

---

✨ SYNOPSIS ✨

uint64_t amdgpu_vm_tlb_seq (struct amdgpu_vm *vm );

like yes that's the whole thing, she's compact 💅

---

🌸 ARGUMENTS 🌸

• vm — the amdgpu_vm structure to query. that's it, that's the one input, she's low maintenance 🫶

---

💖 DESCRIPTION 💖

Returns the tlb flush sequence number 🔥

and what does that number mean, you ask? okay so: whenever this sequence number changes, that's your signal that the VM TLBs need to be invalidated. that's the whole vibe check — number changed, TLBs gotta get flushed, no cap 💀

so like, compare the number you got before with the number you get now, and if they don't match it's giving "go invalidate those TLBs" ✨

fr fr double-check against the actual amdgpu_vm struct before you go comparing sequence numbers, bestie — the header file is right there and she's your friend 💜
