amdgpu_vm_bo_map(9)

💖 NAME 💖

amdgpu_vm_bo_map — map bo inside a vm.

Okay bestie, this is the amdgpu_vm_bo_map(9) page from the Kernel API Manual, and it’s giving “kernel mapping but make it cute” ✨

🌸 SYNOPSIS 🌸

int amdgpu_vm_bo_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. The device vibe check 👑
• bo_va — bo_va to store the address.
• saddr — where to map the BO.
• offset — requested offset in the BO.
• size — BO size in bytes.
• flags — attributes of pages (read/write/valid/etc.). Basically the page’s personality settings 💅

🦋 DESCRIPTION 🦋

Adds a mapping of the BO at the specefied addr into the VM.

🚨 Object has to be reserved and unreserved outside! This call is not out here doing that for you, bestie. Handle it outside, okay? 🫶

🔥 RETURN 🔥

• 0 for success — slay ✅
• error for failure — not slay, but at least it tells you 😭

Cute lil sign-off: this page lives under ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it’s still amdgpu_vm_bo_map(9) from the Kernel API Manual. Bye bestie! 💖🎀🦋
