| std::vector<DmaDoneEvent> Pl111::dmaDoneEventAll |
All pre-allocated DMA done events.
The PL111 model preallocates maxOutstandingDma number of DmaDoneEvents to avoid having to heap allocate every single event when it is needed. In order to keep track of which events are in flight and which are ready to be used, we use two different vectors. dmaDoneEventAll contains all DmaDoneEvents that the object may use, while dmaDoneEventFree contains a list of currently unused events. When an event needs to be scheduled, the last element of the dmaDoneEventFree is used and removed from the list. When an event fires, it is added to the end of the dmaEventFreeList. dmaDoneEventAll is never used except for in initialization and serialization.
