I was thinking using this to update our graphics software, but then I realized I need to backup GPU states (textures, for example) and recover them before and after the update.

lots of the servers are now using gpus for deep learning, may be adding gpu support to the framework is a good feature.

If such states are preserved while the process that used them is still running then there is nothing to do: They will still be available to the updated program.

I was thinking about memory mapped resources, like memory mapped io. and resource references.

maybe you are right, there might be no problem. I need to read the paper to understand better.

Yes, memory mappings should be preserved, so I can't immediately think why it wouldn't work.
