amdgpu_vm_pt_start(9)

📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_vm_pt_start(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the AMDGPU driver, you need to walk the page directory / page tables, and you need somewhere to start. That's literally this function. It's the lil "go" button for a PD/PT walk, and it lives in the amdgpu_vm_pt.c corner of the kernel fandom. iykyk ✨

🌸 SYNOPSIS 🌸

void amdgpu_vm_pt_start (struct amdgpu_device *adev , struct amdgpu_vm
*vm , uint64_t start , struct amdgpu_vm_pt_cursor *cursor );

it's giving: void, four args, no return value, no drama. returns nothing because the cursor is the whole point. periodt. 💅

🦋 ARGUMENTS 🦋

  • adev — a amdgpu_device pointer. hi bestie, this is your GPU device, the main character of the whole situation 👑
  • vm — the amdgpu_vm structure. the virtual memory vibe holder 🌈
  • start — the start address of the walk. the literal coordinate where your little walk begins 📍
  • cursor — the state to initialize. this is the thing getting set up so the walk can actually happen — iconic, honestly 💖

✨ DESCRIPTION ✨

so basically: this initializes an amdgpu_vm_pt_cursor so you can start a walk. that's it, that's the gig. it doesn't do the walk, it just sets you up so the walk can be done. think of it as the pre-game, not the party 🫶 no cap, that is the entire description, and honestly? we respect the brevity. ate and left no crumbs 🍓

🔥 SEE ALSO 🔥

first up, the source file itself, so you can go read the real thing:

  • ./drivers/gpu/drm/amd/amdgpu/amdgpu_vm_pt.c

and now the whole friend group — all of these are (9) kernel functions, go say hi:

like, that's the whole squad. the DFS girlies, the free girlies, the update girlies — everyone's here 🧚💜

ngl there's no bugs section and no warnings here, so you're chilling. just a clean little init function living its best life 🌸

that's the whole page, bestie — no crumbs left behind 💫 this lil gem spilled out of ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026, filed under amdgpu_vm_pt_start(9). mwah, go walk some page tables 😭💖🎀
