This v9 series adds S4 (hibernation) support for the virtio-gpu driver across 3 patches: freeze/restore hooks, object tracking/restoration, and a PM notifier. The architecture is sound — PM_HIBERNATION_PREPARE sets a flag, freeze unrefs all tracked objects to clean the host side, and restore re-submits them to a freshly started QEMU. The series has been through extensive review already (v9), and the core design is solid.
There are a few issues worth raising: missing error recovery in the freeze path (leaving DRM suspended on timeout), an unnecessary include, use of `int` instead of `bool` for the `no_cb` parameter, and VRAM objects silently not being restored. None are showstoppers, but the error recovery gap in freeze is worth fixing.
