  "message": "vfio-pci: Add KVM INTx acceleration\n\nThis makes use of the new level irqfd support enabling bypass of qemu\nuserspace both on INTx injection and unmask.  This significantly\nboosts the performance of devices making use of legacy interrupts (ex.\n~60% better netperf TCP_RR scores for an e1000e assigned to a Linux\nguest and booted with pci\u003dnomsi).  This also avoids flipping mmaps on\nand off to simulate EOIs, so greatly improves performance of device\naccess in addition to interrupt latency.\n\nSigned-off-by: Alex Williamson \u003calex.williamson@redhat.com\u003e\n",
