reserve_bo_and_vm(9)

okay so bestie, this is reserve_bo_and_vm(9) from the Kernel API Manual — yes, the page name and function name are twinning, main character energy. ✨

💖 NAME 💖

reserve_bo_and_vm — reserve a BO and a VM unconditionally. Not “maybe”, not “if the vibe is right” — unconditionally, periodt. 💅

✨ SYNOPSIS ✨

The signature is right here, bestie — copy it exactly, no autocorrect shenanigans:

int reserve_bo_and_vm (struct kgd_mem *mem , struct amdgpu_vm *vm ,
       struct bo_vm_reservation_context *ctx );

🦋 ARGUMENTS 🦋

• mem — KFD BO structure. That’s the BO, bestie. 🫶
• vm — the VM to reserve. Yes queen, that VM. 👑
• ctx — the struct that will be used in unreserve_bo_and_vms. It’s the context bestie for the unreserve side, iykyk. 💅
