💖 amdgpu_vm_bo_replace_map(9) — Kernel API Manual 💖

okay so bestie, welcome to the amdgpu_vm_bo_replace_map(9) page 💅 this is straight out of the Kernel API Manual and it's genuinely such a mood. grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

amdgpu_vm_bo_replace_map — map a BO inside a VM, but like, replacing the mappings that are already chilling there 👑

🦋 SYNOPSIS 🦋

int amdgpu_vm_bo_replace_map (struct amdgpu_device *adev , struct
amdgpu_bo_va *bo_va , uint64_t saddr , uint64_t offset , uint64_t size ,
uint32_t flags );

🎀 ARGUMENTS 🎀

  • adev — amdgpu_device pointer, i.e. the whole device situation 🖥️
  • bo_va — the bo_va that's gonna store the address, lowkey the main character here
  • saddr — where to map the BO 📍
  • offset — the offset you're requesting in the BO
  • size — BO size in bytes, fr fr
  • flags — attributes of the pages (read/write/valid/etc.) 🏷️

🌸 DESCRIPTION 🌸

so what it does: it adds a mapping of the BO at the specified addr into the VM ✨ and because it's an icon, it replaces the existing mappings while it's at it. like, out with the old, in with the new, no cap.

⚠️ bestie listen — the object has to be reserved and unreserved outside! that's not optional, that's the vibe check. don't come for this function without doing that first 🫶

⭐ RETURN ⭐

0 for success, error for failure. that's it, that's the whole mood 😭💀
