💅 sdma_v3_0_vm_copy_pte(9) — kernel API manual, but make it make sense 🎀

okay so bestie, welcome to the Kernel API Manual ✨ this one's a function page, sdma_v3_0_vm_copy_pte(9), and honestly? it's giving "small function, big responsibilities." let's get into it 🦋

✨ NAME ✨

sdma_v3_0_vm_copy_pte — update PTEs by copying them from the GART 💫

🌸 SYNOPSIS 🌸

void sdma_v3_0_vm_copy_pte (struct amdgpu_ib *ib , uint64_t pe ,
       uint64_t src , unsigned count );

no return value, no drama, just vibes and a void. periodt 💅

🎀 ARGUMENTS 🎀

  • ib — the indirect buffer you're filling with commands. this is your canvas, your little command scrapbook 🖌️
  • pe — addr of the page entry. yes, addr, the manpage said it, we respect it 🫶
  • src — src addr to copy from. the origin point, the source material, the main character 🌟
  • count — number of page entries to update. how many PTEs we're touching, bestie — don't lose track 😤

💜 DESCRIPTION 💜

Update PTEs by copying them from the GART using sDMA (CIK).

that's literally it, that's the whole thing — but like, think about it? you're copying page table entries straight out of the GART with sDMA, and it's the CIK generation doing it. lowkey iconic 🔥 no cap, this is the "just copy the PTEs" girlie of the sdma_v3_0 family and she knows her job 💖

the kernel file lives right here, go say hi to it 👋

  • ./drivers/gpu/drm/amd/amdgpu/sdma_v3_0.c

and now, the whole friend group — the entire sdma_v3_0 squad, in the order the page lists them, because we do NOT skip anyone in this house 🏠✨

twenty-three siblings and one file path, and we listed every single one 💀 iykyk 🌈

ngl bestie, this one's short but she's specific — PTE copying via the GART with sDMA on CIK. memorize the arg order and you're golden 👑

and that's a wrap!! 🎬 signed off from ./drivers/gpu/drm/amd/amdgpu, October 2026, on the sdma_v3_0_vm_copy_pte(9) page itself — slay, go fill that indirect buffer 💖✨🎀🦋🌸💅🫶
