Abstract

Apparatuses, systems and methods for routing requests and responses targeting a shared resource. A queue in a communication fabric is located in a path between the requesters and a shared resource. In some embodiments, the shared resource is a shared address translation cache stored in an endpoint. The physical channel between the queue and the shared resource supports multiple virtual channels. The queue assigns at least one entry to each virtual channel of a group of virtual channels where the group includes a virtual channel for each address translation request type from a single requester of the multiple requesters. When the at least one entry for a given requester is de-allocated, the queue allocates this entry only with requests from the assigned virtual channel even if the empty entry is the only available entry of the queue.
