This is an implementation of single-character virtio-console. Part of the patch is based on barebox implementations.
To test the patch, we can build qemu_arm64_defconfig target. Enable CONFIG_VIRTIO_CONSOLE. And run qemu-system-aarch64 with -device virtio-serial-pci,id=virtio-serial0 \ -chardev file,id=charconsole0,path=/tmp/serialconsolelog \ -device virtconsole,chardev=charconsole0,id=console0 \
With this command, it still uses the on-board UART but not virtio-console. Would you please post test instructions on using virtio-console as the U-Boot serial console? Thanks!
When in U-boot console, type "dm tree" and we should be able to see the virtio-console device.
