Re: [virtio-dev] [PATCH] virtio-gpu: add shared resource feature

Interesting; what's the use case for this? Do we already have a mechanism to import memory to virtio-gpu via importing a bo handle from somewhere else?

Yep, none of the 3D commands is in the specs, thats why
RESOURCE_CREATE_3D_SHARED isn't there too (but, yes, it exists).
