Abstract
In an aspect, an apparatus that includes a first security domain and at least a second security domain obtains, at a virtual machine of the first security domain, a stream identifier associated with the second security domain. The apparatus generates, at the virtual machine of the first security domain, a command to map the stream identifier associated with the second security domain to a first address translation context. The apparatus maps, at a hypervisor device, the first address translation context to a second address translation context that is associated with the second security domain of the stream identifier. The apparatus processes a stream of memory access transactions that includes the stream identifier based on at least the first address translation context or the second address translation context.
