Now that the driver for the Bochs VGA card emulated by QEMU is no longer
limited to x86 architectures [1], this series enables it on arm and
arm64 virtual machines to provide a graphical interface. In line with
that series this also enables console buffering and USB keyboard.
Tested with the Debian 12 installer using GRUB EFI:
$ tools/buildman/buildman -o build/qemu_arm64 --boards=qemu_arm64 -w
$ cd build/qemu_arm64
$ curl -L -o debian.img \
https://cdimage.debian.org/debian-cd/current/arm64/iso-cd/debian-12.0.0-arm64-netinst.iso
$ qemu-system-aarch64 \
-machine virt -cpu cortex-a53 -m 4G -smp 4 \
-bios u-boot.bin \
-serial stdio -device VGA \
-nic user,model=virtio-net-pci \
-device virtio-rng-pci \
-device qemu-xhci,id=xhci -device usb-kbd -device usb-tablet \
-drive if=virtio,file=debian.img,format=raw,readonly=on,media=cdrom
And with one using extlinux.conf:
$ [...]
$ curl -L -o head.img.gz \
https://deb.debian.org/debian/dists/bookworm/main/installer-arm64/current/images/netboot/SD-card-images/gtk/firmware.none.img.gz
$ curl -L -o partition.img.gz \
https://deb.debian.org/debian/dists/bookworm/main/installer-arm64/current/images/netboot/SD-card-images/gtk/partition.img.gz
$ zcat head.img.gz partition.img.gz >debian.img
$ [...]
Both can get to a graphical installer just fine, in addition to U-Boot
video console showing up in a GTK window.
