board/qemu/aarch64-virt/linux.config: enable PCIe and PCI host generic driver Add the CONFIG_PCI symbol due a change in kernel 5.0 [1]. The option was previously enabled by default (default y). "PCI: consolidate PCI config entry in drivers/pci There is no good reason to duplicate the PCI menu in every architecture. Instead provide a selectable HAVE_PCI symbol that indicates availability of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the rest in drivers/pci." Qemu aarch64 provide a PCIe Host bridge but it require CONFIG_PCI_HOST_GENERIC enabled in the kernel. With CONFIG_PCI_HOST_GENERIC enabled PCIe host bridge is detected: $ dmesg pci-host-generic 4010000000.pcie: host bridge /pcie@10000000 ranges: pci-host-generic 4010000000.pcie: IO 0x3eff0000..0x3effffff -> 0x00000000 pci-host-generic 4010000000.pcie: MEM 0x10000000..0x3efeffff -> 0x10000000 pci-host-generic 4010000000.pcie: MEM 0x8000000000..0xffffffffff -> 0x8000000000 pci-host-generic 4010000000.pcie: ECAM at [mem 0x4010000000-0x401fffffff] for [bus 00-ff] pci-host-generic 4010000000.pcie: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [bus 00-ff] pci_bus 0000:00: root bus resource [io 0x0000-0xffff] pci_bus 0000:00: root bus resource [mem 0x10000000-0x3efeffff] pci_bus 0000:00: root bus resource [mem 0x8000000000-0xffffffffff] pci 0000:00:00.0: [1b36:0008] type 00 class 0x060000 $ lspci 00:00.0 Host bridge: Red Hat, Inc.

board/qemu/aarch64-virt/linux.config: enable VIRTIO_FS driver virtio-fs allow sharing a directory between the host and the guest. It require virtiofsd daemon running before starting Qemu. The wiki [1] recommand to enable the following kernel options: CONFIG_VIRTIO CONFIG_VIRTIO_FS CONFIG_DAX CONFIG_FS_DAX CONFIG_DAX_DRIVER CONFIG_ZONE_DEVICE But virtio-fs works fine with only VIRTIO_FS. Note: ZONE_DEVICE can only be enabled on aarch64 since kernel >= 5.7. ARCH_ENABLE_MEMORY_HOTREMOVE support is missing for previous kernel [2].
