Hi all, I boot vm with the virtio keyboard on aarch64. It looks UEFI lacks support for the virtio keyboard, so I can't do any keyboard input before the linux kernel driver loads, i.e. edit the grub boot menu. Is there any plan to support it? I find UsbKeyboardDevice attach on UsbIO which implements its protocol interface structure(such as UsbGetInterfaceDescriptor, UsbAsyncInterruptTransfer) defined by UEFI spec, but virtio not. So is there some way to implement similar interfaces?
