From bd36adb8df5d62a2b4d4ded6357fb50b69a508fa Mon Sep 17 00:00:00 2001 From: Jagannathan Raman Date: Fri, 29 Jan 2021 11:46:19 -0500 Subject: multi-process: create IOHUB object to handle irq IOHUB object is added to manage PCI IRQs. It uses KVM_IRQFD ioctl to create irqfd to injecting PCI interrupts to the guest. IOHUB object forwards the irqfd to the remote process. Remote process uses this fd to directly send interrupts to the guest, bypassing QEMU.
