Timestamps are made up of multiple results from the different subqueues, decided by the target stage for the timestamp. Afterwards, when the timestamp query is copied, those individual results will be combined into the final result. For the computation of the final result, each timestamp query also has a separate info field, containing the info required to perform the copy. Timestamps inside a renderpass which cover the fragment subqueue need to be deferred until after the RUN_FRAGMENT job. This happens via a linked list of timestamps in the subqueue context. Once in each primary command buffer, the syncobjs of the queries completed so far are signalled. The list of those queries is part of the subqueue context as well.
