amdgpu_vm_pt_level_shift(9)

✨ NAME ✨

Okay bestie, welcome to the Kernel API Manual page for amdgpu_vm_pt_level_shift 💅 — and the job is literally in the name: return the addr shift for each level ✨ no cap.

✨ SYNOPSIS ✨

unsigned int amdgpu_vm_pt_level_shift (struct amdgpu_device *adev ,
unsigned int level );

✨ ARGUMENTS ✨

• adev — amdgpu_device pointer 🫶
• level — VMPT level 🌸

✨ RETURN ✨

The number of bits the pfn needs to be right shifted for a level 🔥

Like, that’s the whole tea: you pass in the level, and it gives you back the shift amount. Iconic behavior, honestly 👑.
