Our timelines are more than just a seqno. They also provide an ordered list of requests to be executed. Due to the restriction of handling individual address spaces, we are limited to a timeline per address space but we use a fence context per engine within. Our first step to introducing independent timelines per context (i.e. to allow each context to have a queue of requests to execute that have a defined set of dependencies on other requests) is to provide a timeline abstraction for the global execution queue.
