hi, I had make virtio_console work OK on my environment（armv8）, But I meet two question when I add virtio net with virtio_console meanwhile. Question1: "add_io_port_range@io.c:111 Requested ioport range 0x6200-0x6600" for VIRTIO CON overlaps with existing range 0x6200-0x6600 for VIRTIO PCI NET According to the print above: common_make_virtio_con(virtio_emul_vm, vm->pci, vm->io_port, VIRTIO_IOPORT_START, VIRTIO_IOPORT_SIZE, VIRTIO_INTERRUPT_PIN, VIRTIO_CON_PLAT_INTERRUPT_LINE, backend); common_make_virtio_net(virtio_emul_vm, vm->pci, vm->io_port, VIRTIO_IOPORT_START + 0x1000, VIRTIO_IOPORT_SIZE, VIRTIO_INTERRUPT_PIN, VIRTIO_NET_PLAT_INTERRUPT_LINE, backend); a、above two function，I found they use the same VIRTIO_IOPORT_START， I modify VIRTIO_IOPORT_START of common_make_virtio_net to （VIRTIO_IOPORT_START + 0x1000）, is it OK? b、I also found（VIRTIO_CON_PLAT_INTERRUPT_LINE == VIRTIO_NET_PLAT_INTERRUPT_LINE）,is that OK? Whether it should be make interrupt line different ? Question2: "_utspace_split_alloc@split.c:272 Failed to find any untyped capable of creating an object at address 0xc0001000 Failed to find device cap for 0xc0001000" According to the print above: a、my PCI region define as below: #define PCI_CFG_REGION_ADDR 0xC1000000 #define PCI_IO_REGION_ADDR 0xC0000000 #define PCI_CFG_REGION_SIZE 0x1000000 #define PCI_IO_REGION_SIZE 0x1000 #define PCI_CFG_BAR_MASK 0xFFFFFFFF I found 'virtio_net_init' and 'virtio_console_init' will call the same function 'install_virtio_vpci_device', net and console will have the same PCI_IO_REGION_ADDR ? is it OK? b、If I want to support two or muti virtio device, which should I add a new macro define for virtio_net in a? for example add PCI_IO_REGION_ADDR for net or add PCI_CFG_REGION_ADDR ? c、Can you give me some list file to change for support for support net and console meanwhile? Thank you very much.
