Title:
arm64: Build stubble kernel
Status in linux package in Ubuntu:
New
Status in linux source package in Questing:
New
Bug description:
For arm64 we want our default signed kernel to be bundled with stubble and
dtbs.
This bug tracks progress on the integration work needed.
stubble will allow us to load device trees automatically as part of an
EFI boot stub on Qualcomm Snapdragon laptops and have them
signed/verified with UEFI secure boot. A more detailed explanation for
how and why we plan this is available in the form of a spec at
https://discourse.ubuntu.com/t/spec-stubble-a-secure-boot-friendly-
device-tree-loading-efi-stub/66560
