ENUM DRM_PANTHOR_VM_STATE(9)

💖 enum drm_panthor_vm_state(9) — VM states 💖

okay so this is the Kernel API Manual page for enum drm_panthor_vm_state, bestie, and it's literally all about VM states. It's giving kernel lore, but make it cute. 🫶

✨ NAME ✨

enum drm_panthor_vm_state — VM states. Lowkey the whole personality of this page is "what state is your VM in?" 💅

🌸 SYNOPSIS 🌸

enum drm_panthor_vm_state {
    DRM_PANTHOR_VM_STATE_USABLE ,
    DRM_PANTHOR_VM_STATE_UNUSABLE

};

🎀 Constants 🎀

DRM_PANTHOR_VM_STATE_USABLE — VM is usable ✨

This VM is usable, periodt. New VM operations will be accepted on this VM. Slay. 💖

DRM_PANTHOR_VM_STATE_UNUSABLE — VM is unusable 💀

VM is unusable. Something put the VM in an unusable state (like an asynchronous VM_BIND request failing for any reason). Not cute. 😭

Once the VM is in this state, all new MAP operations will be rejected, and any GPU job targeting this VM will fail. UNMAP operations are still accepted, bestie — at least there's that.

The only way to recover from an unusable VM is to create a new VM, and destroy the old one. No cap: there is no in-place glow-up for this one. 💅
