XIVE2 has the concepts of a Group of interrupts and a Crowd of interrupts (where a crowd is a group of Groups). These patch sets are associated with: - NVGC tables - Group/Crowd level notification - Incrementing backlog countets - Backlog processing - NVPG and NVC Bar MMIO operations - Group/Crowd testing - ESB Escalation - Pool interrupt testing
