amdgpu_vm_ready(9)

✨ amdgpu_vm_ready ✨

okay so this is amdgpu_vm_ready from the Kernel API Manual, and it's basically the vibe check function for your GPU's virtual memory 💅

---

🌸 SYNOPSIS 🌸

bool amdgpu_vm_ready (struct amdgpu_vm *vm );

bestie it takes exactly one thing and hands you back a bool. that's it. that's the whole entry point 🎀

---

🦋 ARGUMENTS 🦋

• vm — the VM you wanna check. that's the one. the only one. the main character VM 🔥

---

💖 DESCRIPTION 💖

so what does it do? it checks if all the VM PDs/PTs are ready for updates ✨ like, it's literally going down the list making sure everything's in a state where you can actually touch it. no chaos, no half-finished nonsense, just a clean little readiness check 🫶

---

⭐ RETURN ⭐

it returns True if the VM is not evicting and all the VM entities are not stopped 💀

so like — if the VM is busy getting evicted, or if any entity is sitting there stopped, you get False, and that's your signal to chill and come back later 🙈

ngl this return value is doing double duty — two separate conditions, both of which have to be happily false-ish for you to get a True. respect the hustle 👑
