This RFC comes from the recent discussion on buffer sharing [1],
specifically about the need to share resources between different
virtio devices. For a concrete use case, this can be used to share
virtio-gpu allocated buffers with the recently proposed virtio video
device [2], without the need to memcpy decoded frames through the
guest.

[2] https://markmail.org/thread/yb25fim2dqfuktgf
Changes v1 -> v2:
Rename exported resource to exported object
Rename the virtio-gpu export command
David Stevens (2):
content: define what an exported object is
virtio-gpu: add the ability to export resources

Wrong list- this belongs on virtio-comment.
dev is for implementation discussions.
