it does feel too many that it should be included by default, not sure why the rest of the tty/serial drivers are not included, or how come this one is not scoped under usb/hid, it is fairly small, and built on arm64 only i think, thus it is useful to include by default - as at best it is unlikely to impact initrd sizes much, and expanding support of generic kernels on arm64 is very much in scope for Ubuntu.

However, this requires the qcom_geni_serial driver to operate. That driver is available as a built module already, but only on the rootfs. It is not included in the initramfs by default. The problem with this is that the console is activated quite late in boot, which reduces it's usefulness in debugging kernel/boot issues. Also, when it finally does come up, the console cannot operate as a login interface (no login prompt is provided) because the interface is initialized after systemd is operational. I can manually add the module to the initramfs by adding "qcom_geni_serial" to /etc/initramfs-tools/modules and running update- initramfs, however this is quite inconvenient. It requires me to remove the storage from the platform, and modify it on another system. Given that the default initramfs already contains a large number of serial drivers, it feels like qcom_geni_serial should be included by default which would give an optimal "out of the box" experience on a number of Qualcomm based platforms.
