💅 amdgpu_vm_bo_find(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is amdgpu_vm_bo_find(9), and she is literally here to find the bo_va for a specific vm & bo. no cap, this one is short but important 🎀

🌸 NAME 🌸

amdgpu_vm_bo_find - find the bo_va for a specific vm & bo

✨ SYNOPSIS ✨

struct amdgpu_bo_va * amdgpu_vm_bo_find (struct amdgpu_vm *vm , struct
       amdgpu_bo *bo );

🫶 ARGUMENTS 🫶

• vm — requested vm. the vm in question, the one you're searching inside 💖
• bo — requested buffer object. the buffer object you're looking for 🦋

💅 DESCRIPTION 💅

Find bo inside the requested vm. periodt. it searches inside the bos vm list for the requested vm.

Returns the found bo_va or NULL if none is found. so if it's not there, you get NULL — not a meltdown, just a NULL 😭

⚠️ real talk, bestie: Object has to be reserved! this is not a vibe-check-optional situation, okay? reserve the object first, fr fr 💀

🎀 RETURN 🎀

Found bo_va or NULL. that's the whole return vibe: found bo_va, or NULL 🫶
