amdgpu_vm_assert_locked(9)

💖 NAME 💖

okay so welcome to amdgpu_vm_assert_locked(9) from the Kernel API Manual, bestie. The name is literally amdgpu_vm_assert_locked — check if VM is correctly locked. That's the whole assignment, and it's honestly kind of iconic that a function can be this direct. ✨

✨ SYNOPSIS ✨

the signature is short, sweet, and ready for the group chat:

void amdgpu_vm_assert_locked (struct amdgpu_vm *vm );

🎀 ARGUMENTS 🎀

• vm — the VM which schould be tested (yes bestie, that's the original spelling, and we're preserving the typo like a little vintage charm 💀).

💅 DESCRIPTION 💅

this one is a pure vibe check for locking: Asserts that the VM root PD is locked. no cap, that's the whole job. it returns void, so it's not handing you a value back — it's just there to assert the lock situation on the VM root PD. periodt. 🔥
