- Add VirtIO input device driver (device ID 18) reading from eventq - Translate Linux keycodes (WASD, arrows) to InputEvent - Kernel probes for VirtIO input device, falls back to UART - Add -device virtio-keyboard-device to run-gui Makefile target - input-qemu tries VirtIO first, falls back to UART
