The XIVE (External Interrupt Virtualization Engine) is a new interrupt controller present in IBM's POWER9 processor. It's a very powerful, very complex device using queues and shared memory to improve interrupt dispatch performance in a virtualized environment. This yields a ~10% performance improvment over the XICS emulation mode, measured in both buildworld, and 'dd' from nvme to /dev/null. Currently, this only supports native access. MFC after: 1 month |
