The VirtIO spec states that "Upon receipt of a VIRTIO_CONSOLE_CONSOLE_PORT message, the driver SHOULD treat the port in a manner suitable for text console access and MUST respond with a VIRTIO_CONSOLE_PORT_OPEN message, which MUST have value set to 1". See https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html#x1-3330002. The current driver implementation, however, does not comply with that and only sends PORT_OPEN messages upon receipt of PORT_OPEN messages. This causes a problem in platforms like Apple's Virtualization Framework, where PORT_OPEN messages are not sent back to the driver after CONSOLE_PORT messages are received by the device, a behaviour that is compliant with the VirtIO specification. This patch addresses this issue by always responding CONSOLE_PORT messages with PORT_OPEN messages. Signed-off-by: Pedro Tôrres <t0rr3sp3dr0@gmail.com> |
