📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_gmc_get_pde_for_bo(9) 💅

okay so bestie, we're in the Kernel API Manual today and the main character of this page is amdgpu_gmc_get_pde_for_bo — say it with me, it's a mouthful, but it eats, fr fr. This is the one that goes and fetches you the PDE for a BO. iconic behavior honestly 🎀

✨ SYNOPSIS ✨

void amdgpu_gmc_get_pde_for_bo (struct amdgpu_bo *bo , int level ,
       uint64_t *addr , uint64_t *flags );

like yes it returns void, no it's not giving you a value back — it fills in your pointers, that's the whole vibe 💅

🦋 ARGUMENTS 🦋

  • bo — the BO you want the PDE for. like, the actual buffer object, bestie. it's the star of the show 👑
  • level — the level in the PD hirarchy. yes, the spelling is hirarchy in the original and we're not touching it, it's iconic in its own way 😭
  • addr — the resulting addr. this one's an output, so it gets written for you ✨
  • flags — the resulting flags. also an output, also gets filled in, no cap 🫶

🌸 DESCRIPTION 🌸

lowkey the whole job is this: get the address and flags to be used for a PDE (that's a Page Directory Entry, iykyk). that's it, that's the plot. she's a getter, she gets 🎀

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/gpu/drm/amd/amdgpu/amdgpu_gmc.c — go read it if you're feeling brave, it's giving main character energy 🧚

and here's the whole friend group, like a group chat you got added to:

ok that's the whole page, no filler, we ate and left no crumbs 🍓

that's a wrap bestie!! mwah 💖 this came to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and the page itself is amdgpu_gmc_get_pde_for_bo(9) — slay, goodbye, see you in the next manpage 🦋✨
