- CoastalCoder 3y agoAre there GPUs that allow enough internal state to be dumped / reloaded for a migration like that to work? (I'm asking from pure ignorance.)
- monocasa 3y agoYou can do it in the vfio driver by just keeping the bookkeeping information around as resources are created.
- tryauuum 3y agoI'm also ignorant about this topic, but it's certainly accomplishable. There's a (quite old) video with demonstration: https://youtu.be/jjkcPn19fcs https://youtu.be/jjkcPn19fcs
