From fe43cc5bde32d8bba930242f34ad55002ea4819e Mon Sep 17 00:00:00 2001 From: Bibo Mao Date: Tue, 28 May 2024 16:20:53 +0800 Subject: tests/libqos: Add loongarch virt machine node Add loongarch virt machine to the graph. It is a modified copy of the existing riscv virtmachine in riscv-virt-machine.c It contains a generic-pcihost controller, and an extra function loongarch_config_qpci_bus() to configure GPEX pci host controller information, such as ecam and pio_base addresses. Also hotplug handle checking about TYPE_VIRTIO_IOMMU_PCI device is added on loongarch virt machine, since virtio_mmu_pci device requires it.
