For instance, Gunyah vCPUs are exposed to the host as a resource. The Gunyah vCPU function will register a resource ticket and be able to interact with the hypervisor once the resource ticket is filled. Resource tickets are the mechanism for functions to acquire ownership of Gunyah resources. Gunyah functions can be created before the VM's resources are created and made available to Linux. A resource ticket identifies a type of resource and a label of a resource which the ticket holder is interested in. Resources are created by Gunyah as configured in the VM's devicetree configuration. Gunyah doesn't process the label and that makes it possible for userspace to create multiple resources with the same label. Resource ticket owners need to be prepared for populate to be called multiple times if userspace created multiple resources with the same label.
