Public bug reported:
[Impact]
jammy:linux-gke does not have the nvme driver built-in. The ARM64 CPU platform
on GCE, Ampere Altra, only supports the NVMe storage interface, meaning we
cannot boot arm64 images without initramfs. The initramfs is used only to load
the nvme driver module.
[Fix]
Set CONFIG_BLK_DEV_NVME=y and CONFIG_NVME_CORE=y for arm64.
[Test]
Check that nvme is built-in, e.g., grep nvme.ko /lib/modules/$(uname
-r)/modules.builtin
[Where problems could occur]
Unlikely to have any issues apart from an increased arm64 kernel image size.
