🦋 amdgpu_vm_free_mapping(9) — Kernel API Manual 🦋

okay so bestie, this is the amdgpu_vm_free_mapping(9) page from the Kernel API Manual, and it’s literally the “free a mapping” helper. Short page, iconic energy, every detail intact. 💅

🎀 NAME 🎀

amdgpu_vm_free_mapping — free a mapping.

✨ SYNOPSIS ✨

void amdgpu_vm_free_mapping (struct amdgpu_device *adev , struct
amdgpu_vm *vm , struct amdgpu_bo_va_mapping *mapping , struct dma_fence
*fence );

🧚 ARGUMENTS 🧚

• adev — the amdgpu_device pointer. device bestie energy.
• vm — the requested vm. requested vm, exactly as it says.
• mapping — the mapping to be freed. We’re freeing this one, periodt.
• fence — the fence of the unmap operation. unmap fence, noted.

🌸 DESCRIPTION 🌸

So this function frees a mapping and makes sure to decrease the PRT usage count if applicable. That’s the whole vibe: mapping gets freed, PRT usage count goes down when it applies. 🫶
