reserve_bo_and_cond_vms(9) 🎀

okay bestie, this one is from the Kernel API Manual and it's lowkey a whole reservation moment: reserve a BO and some VMs conditionally. the way it's giving kernel internals but make it cute? obsessed. 💅

✨ NAME ✨

reserve_bo_and_cond_vms — reserve a BO and some VMs conditionally. 🦋

🌸 SYNOPSIS 🌸

int reserve_bo_and_cond_vms (struct kgd_mem *mem , struct amdgpu_vm *vm , enum bo_vm_match map_type , struct bo_vm_reservation_context *ctx );

🦋 ARGUMENTS 🦋

• mem — the KFD BO structure. 💖
• vm — the VM to reserve. If it's NULL, then all VMs associated with the BO is used. Otherwise, a single VM associated with the BO. 🫶
• map_type — the mapping status that will be used to filter the VMs. ✨
• ctx — the struct that will be used in unreserve_bo_and_vms. 🎀

💜 DESCRIPTION 💜
