amdgpu_vm_get_task_info_vm(9)
π amdgpu_vm_get_task_info_vm(9) β bestie edition
okay so this is a page straight outta the Kernel API Manual, and it's about one tiny little function that fishes task info out of a VM. short page, but it's important, so let's go π«Ά
β¨ NAME β¨
amdgpu_vm_get_task_info_vm β literally extracts task info for a vm. that's the whole job. no cap.
πΈ SYNOPSIS πΈ
struct amdgpu_task_info * amdgpu_vm_get_task_info_vm (struct amdgpu_vm
*vm );
π ARGUMENTS π
vmβ the VM to get info from. like, this one, the one you're pointing at. hand it over and it'll spill the tea π
π¦ DESCRIPTION π¦
okay so here's the vibe: it returns the reference counted task_info structure. read that again β reference counted, bestie, which means you do not just take it and walk away like it's yours.
you gotta reference it down with amdgpu_vm_put_task_info. that's the deal. take the info, but clean up after yourself or it's giving leak energy π

your girl did not skip a single one of these, i promise. first up, the source file itself:
