Description Chester Lin 2023-09-25 03:32:34 UTC 
Plan to submit a new package arm64laptop-firmware-dt in hardware:boot and then openSUSE:Factory, which installs sc8280xp-lenovo-thinkpad-x13s.dtb on ESP since the Lenovo X13s' ACPI doesn't support Linux and its UEFI FW has to preload the DTB file from ESP and then apply some runtime DT overlays before booting to grub2 and then Linux. Without preloading the DTB, the system wouldn't boot since the UEFI FW does not contain a default DTB.

Do you plan to add device tree files for other laptops or this is
only for Lenovo X13s? If this just for one laptop arm64laptop sounds
to generic to me.

I expect that this package will cover X13s and all other laptops that need this kind of DTB installation at present or in the future. [e.g. The next gen of X13s]

Ping.

Could any maintainer of hardware:boot review this SR? Thanks.
Comment 6 Chester Lin 2023-10-20 08:29:08 UTC 
Refreshed to V4. [Revoked v3 due to code alignment issues]

The arm64laptop-firmware-dt package has been accepted by the factory. The next step is to have this package in installation-images.

Hi Steffen,

I have created a PR here, could you please help to review it? Thanks.
